On the pipe 1216141816202025, is it for 4 points, 5 points, 6 points, 1 inches of ground heating pipe?
(four) excellent resistance to agingA. has good temperature resistance, high density PE working temperature -40~65 DEG C, cross linking PE working temperature -40~95 DEG C.B. anti-aging properties, cold brittle temperature is low, anti ultraviolet, anti-aging ability, in the absence of high heat and strong ultraviolet radiation conditions, 50 years of service life is recognized life time. After the aluminum plastic compound, enables in the withstanding pressure, the shock resistance ability to strengthen.(five) excellent health performance of aluminum-plastic composite pipe lining for the health level of the PE process without any lead such as heavy metal stabilizer, does not contain harmful ingredients and plasticizer, no mildew and microbial breeding, clean sanitation. The intermediate aluminum layer isolates oxygen and the gas permeability is 0.
4., antistatic, easy to flammable fluid delivery;5. good electromagnetic shielding performance;6., good flame resistance, to achieve GB8624 refractory (B1) level;7. good insulation performance.(two) hydraulic performance of aluminum-plastic composite pipe inner surface roughness of thin wall excellent, very smooth, fluid friction resistance is small, no fouling phenomenon which affects the flow of water flux than the metal pipe, and because it has a certain flexibility, can effectively reduce the water supply of water hammer and fluid pressure shock and noise.
Its advantages and disadvantages:(1) good mechanical performance;1., good pressure resistance, shock resistance, rupture resistance2., with a strong plastic deformation ability, can be greater than 5D radius within the arbitrary bending, without heating, not rebound; (D for pipe diameter)3. light weight, same flow diameter composite pipe weight is 1/3 of steel pipe, 1/12 of galvanized pipe;
PEX floor heating pipe joints, pipe fittings are used for special connection with soft star joints, plastic materials are used to connect the machinery.Comparison of advantages and disadvantages between aluminum plastic tube and PEX tubeAluminum tube: plastic composite pipe is a pipe is more popular in previous years on the market, the current market there are relatively well-known HSBC and Kim, due to its lightweight, durable and convenient construction, its flexibility is more suitable for use in the home. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and cold contraction, it will cause the wall of the pipe to be dislocated so as to cause leakage.
