Ideal for pipes made of PEX and PVC chloride

Main advantages of plastic pipes in this case – light weight, smooth walls, corrosion resistance, ease of installation. Such pipes can be cut with a hacksaw simple: networks are easily assembled by hand with bells, couplings and fittings with rubber sealing rings. Web of PVC pipe can be assembled also using adhesives and welding. Companies produce a wide range of fittings: corners, tees, reducers, etc. Another rational scope of polyvinyl chloride pipes – drainage system from the roofs.

Greater versatility than PE pipes, different polypropylene (PP) pipes. Speaking of polypropylene pipes, it should be noted that the quality of such pipes significantly affect the quality of raw materials. The best raw material for polypropylene pipe is copolymer polypropylene Random type 3 (RRR 80), known under the brand name <Fuziolen>. These raw materials used by the largest firm <Aquatherm> exercising device 35% of polymeric pipelines in Europe.

Polypropylene (PP) pipes are harder than plastic, and systems of them are going through fittings: corners, tees, etc. Systems of PP-pipe-detachable. They are assembled by diffusion bonding. To apply for a thin branch from the trunk with a large diameter, there are special fittings. For PP-pipe joints with metal parts (valves, mixers) are made with special fittings are molded them brass elements.

Polypropylene pipes can be used successfully for the internal systems of hot and cold water and heating systems in individual cottage construction. In such cases, the longevity of systems up to 50 years.

In the late 60 – early 70 years. XX. there was one of the most important events in the technology of polymers: appeared transversely crosslinked polyethylene – PEX. Cross-linking of linear molecules of polyethylene increased its heat resistance and strength, but the polymer lost the ability to weld. For cross-linking using high density polyethylene (REND) by merging several techniques using ionizing radiation, peroxides, and organosilicon compounds (silanol merging).

PEX pipes in European countries occupied first place among the plastic pipes. They can operate at temperatures up to 95 ° C and at an operating pressure up to 2 MPa (20 atmospheres). In such settings, PEX pipe can be recommended for water systems (hot and cold), and for heating in apartment buildings.

Pipes: copper, PEX, PEX, steel, installation of heating pipes

Piping for heating systems are its main “blood vessels”. Obviously, the selection and subsequent installation of pipes must be handled with due care.
Pipe

Modern range of pipes for heating, submitted by various manufacturers, is very great. The most common variations of pipelines are:

* Steel, galvanized steel, stainless steel;
* Copper;
* PEX (metal-PEX, polyethylene, PEX reinforced with aluminum).

Copper pipes

Copper tubes for heating, many believe the leader in durability, reliability and maintainability of compounds. Its unique copper pipe is also its very low internal resistance – 40 (!) Times less than that of steel pipe. This factor allows to make copper heating pipes are very thin. The disadvantage of copper wiring is its cost – it is about 2.5 times the cost of wiring for heating PEX.

Copper pipes are good by the fact that they can hide in the walls of the house, followed by incorporation. Installation of copper pipe connection method involves brazing silver-solder. Experts note that the copper pipe – it is virtually the only way to get absolutely reliable system, capable to serve for more than one generation.
Pipe
PEX pipes

PEX is connected with the special equipment, which heats the PEX to the melting temperature, and thus the fitting is welded to the pipe. If the connection is cut crosswise, then the weld is not visible – materials pipes and fittings literally mixed together. This connection is very reliable.

Deficiencies of PEX in comparison with copper: a large thickness of pipes and fittings, a large exposure to temperature deformation, a high degree of aging at high temperatures (over the years, pipelines have become more fragile, like the long lain in the ground a PEX bag). The guaranteed service life of the heating system of PEX is 15 … 30 years.

Pipe cross-linked polyethylene (PEX) is different from PEX only more flexible and way to connect. These pipes extend a special apparatus, are inserted into the fitting, then the apparatus is removed, and the pipe is securely compress fitting. The main disadvantages of such a pipe – a limited lifetime at high temperatures (like PEX), and a very high flexibility. Beautiful outdoor wiring to make such a pipe is practically impossible – it has to hide in the walls.
Metal PEX pipe
pipe

This pipe is a layer cake: the inner layer – cross-linked polyethylene, then a layer of glue, then a layer of aluminum, re-glue, and, finally, the outer layer of polyethylene or other material. In all of these layers superimposed on top brass fittings.

The main advantages of metal pipes for heating are:

* Kislorodonepronitsaemost that can slow the process of corrosion and wear of the heating equipment;
* A low coefficient of linear expansion, which avoids additional compensator mounting highways;
* High mechanical strength;
* Resistance to corrosion and deposition of sediments on the inner surface;
* Antistatic;
* Low hydraulic resistance.

Metal pipes are by pressing or threaded connections without the use of welding. This will reduce the cost of installation and receive an environmentally safe system of heating.
Steel pipes
Steel pipes

Steel pipes are widely represented in the market. The disadvantages of steel pipes should include the need for welding work when installing the system and corrosion processes taking place in their walls. Such defects are deprived of galvanized pipes, if they use the mounting fittings. In this case, both types of metal pipes are heavier, and work with them requires a certain skill.

The most serious shortcoming of steel pipes is their overgrowing the wall coating, which dramatically reduces their capacity and leads to complete overgrowing after several years of operation.

Flow pipes in the heating system of private homes will depend on the selected owner wiring (double-pipe or pipe). Modern heating system, especially for large-area, twin-tube wiring means to regulate the temperature in each heated room with temperature regulators. The only advantage of Single pipe scheme – lower cost.

Cross linked polythene is better choice for warm floors

The word PEX is an acronym for cross linked polythene. The material PEX can be shaped into tubes that can be used for various purposes. Pex tubing can be used at homes or in commercial buildings, under the floors for floor heating, to carry chemical, slurry, sewage, oil and natural gases from off shore. This tubing system can be used instead of PVC or CPVC. It is safe to use for drinking water as it is chlorine resistant. This can also bear high temperature due to which it is highly recommended for floor heating purposes.

As the PEX tubing is highly flexible, it can be easily bent and twisted due to which can be used with few connectors and joints. The problem of leakages is minimized and the installation time is less thereby reducing the cost for plumbing and its maintenance. In order to use PEX tubing, proper tools are required. A proper cutter is required to cut the tube evenly so that it has no rough edges. Some of the essential tools that are required include copper crimp clamp to hold the fittings together. The tubing contracts or expands by one inch with a difference of 10 degrees of temperature.

PEX – Most popular choice of plumbers!

The word PEX tubing has become a common word with people who are into plumbing. It is polythene which is cross- linked and an acronym is used to give it an easier name PEX. It can be molded into tubes that can be used for various purposes. This type of tubing is one of the long lasting materials that are in use for many purposes. The material is chlorine resistant so drinking water can safely be transported in it. PEX tubing has become an alternative to PVC and CPVC pipes in many places. The tubing is used in hydronic radiant heat tubing, in the insulation of high tension electric cables, household water pipe lines etc. Their size may vary from 1/4 inch to 4 inches. The sizes which are predominantly used are 1”, ¾” and ½”.

PEX tubing can be used for off shore natural gas, oil transportation; chemical slurry and sewage can also be transported. The tubing is widely being used for various domestic purposes as well. To use PEX, lesser fittings are required to fit a pipeline. No elbows are needed to turn it at the corners. The flexibility of this tubing system is unbelievable. As PEX tubing can be fixed with lesser fittings, the chances of leakage are minimized. It also has a lesser chance of bursting as it is highly flexible and expandable. As the water freezes or expands due to cold or heat, it can effectively withstand such extreme temperatures. While installing, care should be taken to use the insulating material locally prescribed. PEX tubing can be snapped into any connector and used with ease. There is no need to screw the pipe; it just has to be pushed to fit in.

PEX radiant heating tubing is being used in countries where the temperatures are pretty low; to keep the floors warm. PEX radiant heating tube is placed under the floor to keep it warm. Refrigeration warehouses and Ice rinks are also making good use of this tubing. Hydronic radiant heating systems also use this tubing as it can withstand great heat. The popularity of this tubing is because of its exceptional capacity to withstand heat or cold, its flexibility and ease in handling and non corrosive properties. PEX tubing is available in varied colors. It has become quite common to use blue for cold and red for hot water in homes or places where both hot and cold water is used.

Material PEX Borealis RA-130E

The new material is PEX, Borealis RA-130E is designed specifically for the manufacture of pipes and PEX fittings used in water and heating systems.

Borealis RA-130E is included in the classification of PEX materials under the symbol PP-R-100 (PEX Random Copolymer – PP-R), and in the near future he will be able to displace well-known brand today PEX PP-R-80.

The new material has passed the temperature, strength and hygiene tests in a number of independent organizations. For example, temperature and strength tests at temperatures ranging from plus 20 to plus 110 ° C were carried out in a European center of Bodycote Polymer (Sweden) by methods that meet international quality standard ISO 9080 and in accordance with the instructions DVGW W544 Testing Center German association of industries of gas and water (Karlsruhe).

The following table summarizes the obtained during the test values of the maximum operating pressure (MPa) for PEX RA-130E (PP-R-100). Ibid, for comparison, are the requirements for standard PEX PP-R-80.

The results of comparative tests of PEX Borealis RA-130E (PP-R-100) with four standard values of temperature

Values in the table the maximum operating pressure can be used as input parameters in the calculation of pipelines in the water and heating systems.

During studies at plus 110 C, as a coolant used not only hot water, but superheated steam. During prolonged heat stress were recorded various states of the material, reflecting the dynamics of his condition. The result was a family of “isotherms strength” RA-130E (PP-R-100) at various fixed temperatures. These isotherms represent a set of dependencies, change the maximum operating pressure (pressure stress) as a function of the life of the material at fixed temperatures.

When operating at high temperatures 95-110 C service life of pipelines made of a new modification of PEX will be 25-30% higher than that of pipes made from standard PEX PP-R-80.V water systems should be applied pipelines hygienically safe materials. In European countries, there are a number of normative documents, strictly regulating the procedure for confirmation of the claim. Drinking water, long time in pipelines must not change the taste and smell of purchase. PEX PP-R-80 for thirty years been subjected to independent auditing organizations, and the testimony of impeccable hygienic characteristics of the material is widely used not only in pipelines, but also for food packaging.

Testing center of German industry association of gas and PEX plumbing (Karlsruhe), regularly publishes “worksheets” – quality certificates, which confirm that the tubes made from Borealis RA-130E (PP-R-100), drinking water remains clean.

To date, modification of PEX “Borealis RA-130E” (PP-R-100) has already certified more than 20 countries, including Canada.

Compare plumbing pipes

The latest generation of pipe – a tube made of PEX. Compared to other plumbing supplies, PEX tubing have several advantages:

1) The best raw material for PEX tubing serves random polymer PEX type 3 (RRR 80). This lightweight and durable PEX, referring to the category of thermoPEXs. It is chemically resistant to most solvents – both acidic and alkaline type. Of particular interest is the thermal versatility PEX: the pipe from it operated at temperatures from -10 ° C to +80 ° C. Short pipes can withstand higher temperatures up to +90 ° C. Due to the elasticity of the material, the water in PP tubes can freeze a number of times without destroying them.

2) PEX was obtained by modifying the structure of PEX, that is added to the molecular chain of the ethylene molecule, which improves the mechanical properties of PEX (viscosity, elasticity, high strength).

3) World recognized that this statistical PEX most valuable. It is characterized by the highest strength and durability at elevated temperatures, which resulted in their widespread use in everyday engineering networks. This contributes to the low thermal conductivity of the PPR. Its coefficient of thermal conductivity equal to 0.23 W / m * ° C.

4) PEX does not harm the environment. In his treatment and recycling does not generate environmentally harmful substances. In addition, PEX is suitable for disposal without the addition of environmentally harmful substances.

Usage high density cross-linking plastic

Pipes made of PEX appeared in the mid-50′s. One of the advantages of these tubes is that they are resistant to low temperatures down to -20 C. This makes it possible to operate these tubes and hold them to strip, even in winter conditions. PEX tubing are joined by mechanical means – brass or PEX PEX fittings. Scope of application – mostly cold water. At higher temperatures the strength of PEX decreases, and it goes into PEX-viscous state. PEX is aging rapidly under direct sunlight. Therefore, the use of PEX tubing in outdoor open networks to stabilize, filling the polymer with soot.

At the beginning of 70 years there was a tube of cross-linked PEX, very firm and higher resistance to temperature influences.

Cross-linking of linear molecules of PEX increased its heat resistance and strength, but the polymer lost the ability to weld. For cross-linking using high density PEX, cross-linking is carried out by several methods using ionizing radiation, peroxides, and organosilicon compounds (silanol merging).

Such pipes can already be used in systems for hot water, and pipes, equipped with oxygen barrier and in radiant heating systems.

The next stage of development of the pipe lines are metal-pipe, which are five-layer structure: the main cross-linked PEX tubing, glue layer deposited on its outer surface, a layer of aluminum foil thickness 0,1-0,15 mm, re-bonding layer and outer protective shell PEX. Pipes are made of PEX extrusion, during which the aluminum strip, welded ultrasonically to the joint, is covered on both sides with glue and layers of PEX, suitable thickness.

Metal-pipes are five times lower coefficient of linear expansion and well protected against oxidation. In addition, metal pipes are well bent and hold the shape imparted to them. Of those pipes are well assembled complex on the system configuration, various liner, such as heating appliances. Metal-tube effective in open wiring, especially for connecting various devices (radiators, water heaters, etc.). Unfortunately, the maximum diameter of such tubes to 40 mm, which considerably limits the scope of their application.

Varieties of PEX Fittings

PEX is a cross linked polyethylene substance which is used for manufacturing tubes and pipes. Tubing made from it are known a PEX tubing as they possess unbeatable strength and long lasting durability inherited from PEX. To make use of this tubing suitable for diverse applications they are connected with tolls and devices with the help of PEX fittings. These fittings are units used for connecting PEX tubes with various essential elements. These elements also inherit long lasting durability and adaptability and so are called as PEX fittings.

A diverse assortment of these fittings is manufactured to provide easy installation services for various kinds of applications. Some common types of fittings used are PEX elbows, PEX couplings and tees. These units are used for making installation of PEX tubing easy and less expensive. Among all PEX fittings, most important is PEX elbow, without which the installation of PEX tubing is impossible to carry. These units have been crafted with highly durable materials especially brass so that they can deliver long lasting benefits. Using PEX tubing with PEX fittings reduces the chances of leakage and breakage in order to deliver maximum outcome.

The most common type of PEX pipe fitting is PEX elbow which can be selected from various stores and outlets to serve diverse utilities and functionalities. This type of fitting is used to make right angled joints at specific places. Applications done in larger commercial and residential places involve usage of these types of fittings. One category of PEX elbows is stub out elbows that are mainly used in domestic and potable water applications. Such fittings are particularly used for sinks and basins in kitchen and bathroom. The other category is known as drop ear elbow which are used for water applications requiring direct flow of water. This is especially the case in showers and taps.

A PEX coupling is another most common fitting which is required for the installation applications of PEX tubing. This fitting is used for connecting the two ends of a tube with each other. They benefit in changing the size of pipes and tubes, to turn tight corners and split one tube in two different supply connections. This PEX tube fitting is crafted with robust materials like brass and copper. These materials are coated with an extra layer of polish to make them rust and corrosion resistant. Such PEX fittings are gone through a pre-pressure test to deliver maximum outcome with minimum cost.

PEX fittings are second most important elements for installation after PEX tubing and so it is wise to select appropriate units.

PEX pipe Uponor Wirsbo

PEX manufactured by Uponor Wirsbo in powder form, exposed to deformation to obtain the required grain size. It then weighed on electronic scales and mixed with additives in a mixer using a complex method.

The mixture is placed in a 440-pound (200 kg) vessel. After marking in accordance with the type of pipe, which will be made from this mixture, it is placed in storage for several days.

Finally, the weight is transferred from the vessels into the extruder. 440 pounds (200 kg) of powder is sufficient to produce about 5,000 feet (1,500 m) 3/4-dyuymovyh (20 mm) PEX pipe Uponor Wirsbo-PEX with a wall thickness of 3 / 32 inch (2 mm).

PEX pipe is shaped by extrusion, which holds the raw material in powder form at one end, and, applying heat and high pressure, displaces the tube from the ring-shaped holes on the other end.

During the formation of the pipe occurs and crosslinks. Now it should be noted an important difference between the PEX pipe Uponor Wirsbo-PEX and other PEX pipe made of crosslinked polymers. Crosslinks takes place until the material is in an amorphous state, ie, at a temperature which exceeds the melting of crystals. As a result, eliminated all the crystalline zone, which may have a negative effect on the process of cross stitching. Matching takes place smoothly and without interference.
