Name: pert to warm the pipe fittings, and construction specifications: 16/20/25/32 ★ light weight, easy to transport and installation of construction ★ has good flexibility, making it convenient and economical laying. Recyclable, environmental compliance; ★ pipe bending stress in the bent portion can quickly get loose, no "rebound" phenomenon, to facilitate construction operations, thus avoiding the use of the process due to the stress concentration caused by pipe bends phenomenon destruction; small ★ pipe friction losses within the transmission fluid capacity than the diameter of the pipe PE-X pipe with a large 10%; ★ embrittlement temperature is low, the pipe has excellent low temperature performance, low temperatures in winter can also construction and no warm-up when bent pipes, which can solve the economic losses due to winter temperatures in northern China is too low caused by construction, the minimum bend radius of 5 times the pipe diameter; ★ good chemical resistance, no corrosion, long service life. After the pipe is generally used for several years, due to severe corrosion of the pipe wall and become rough, and thus greatly reduce the flow resistance increase water capacity; ★ good creep resistance, cross-linked polyethylene pipe creep resistance with temperature change, PE-RT due to raw material without crosslinking special board, after a production-molding creep permanent change; ★ at operating temperature of 70 ℃, pressure of 0.82MPa conditions, the pipeline can be safely used for more than 50 years; ★ pipe in the production process does not add any toxic chemicals, smooth wall, no scaling, no bacteria, can be safely used in drinking water and other transportation; ★ 2 times the impact resistance of PE-X pipe; ★ good thermal performance, thermal conductivity rate of 0.4 W / (? m K), in heating applications can save a lot of energy, the use of PE-RT in the heating field can play to their excellent properties; ★ weldability: after the destruction of the system piping, heat can socket welding or electric welding repair. Low temperature hot water radiant floor heating is a highly desirable way of heating. It is a low-temperature hot water as heat medium, through the plastic pipe buried in the floor of the floor heating, radiant heat evenly to the room, the room is a kind of micro-climate adjusted energy heating system. Low temperature hot water radiant floor heating, successfully solved the problem of a shortage of high heat space, large span, short-window of the building, improve the comfort heating, gives a sense of comfort head cold feet warm, consistent regulate the body's physiology characteristics, promote blood circulation, but also reduce the noise floor to achieve a household compartment automatic temperature control, eliminating the dust and odors cooling equipment, service life of up to 50 years.
