High culture landscape works and phyto, as well as new technologies waterproofing basements require the use of flexible plastic drain tubing, hoses. They represent a corrugated hose with a smooth inner surface and drainage system gaps that must be facing up when laying tubes in the ground. For sandy soils, they are available wrapped in a geotextile filter for clay – a surface filter made of coconut fiber, which decays with time, forming an air layer between the clay tubing.
In ventilation systems, air conditioning and smoke extraction and gas hoses used a special kind. They are made of PEX or nylon fabric coated with aluminum or PEX, polyester laminate, thermoplastic rubber, neoprene, thermoplastic polymer poliolefionovogo and reinforced with steel spirals or ply of PEX. They withstand temperatures from -50 to +200 ° C. In comparison with box duct hoses have proven advantages where needed complex geometry laying communications. It is appropriate to their installation between real and false ceilings, as well as in technical areas – basements, garages, where aesthetic requirements are secondary.
Logically, hoses should play the tubing of polymeric materials in the way they connect with each other. Of course, a classic collar, through which the hose is fixed to the transition PEX fittings – a connection less reliable than welded or obtained by crimping. But professionally installed clamp withstands nominal pressure of 8-10 atm. In addition, there are special connectors adapters, reducers, tees, fittings and nozzles that allow connecting hoses to one another and connect them to equipment, as well as the mass of the special accessories that ensure reliable operation of adaptive mobile systems. An interesting know-how owned by a BOW Group. This brass fittings, allowing to connect hoses to the same degree of reliability, which are connected by copper and PEX tubing.
