How to connect PEX pipe and PEX fittings
The materials out of which the connecting pipe and PEX fittings:
PVC (polyvinyl chloride) – from the produce disc valves, diaphragm and Taco mixing valves, filters, Taco heating valves. Possible Temperature – 0-60C, the pressure in the pipes made of PVC can be up to 16 bar. PVC pipe is well resistant to chemicals.
PEX – suitable for PEX plumbing, construction of gas pipelines, sewerage. From it we obtain the body, adapters, PEX fittings. This polymer is inexpensive, that does not affect its properties, he enjoys wide popularity.
Possible Temperature from -40 to +70 C, the pressure can reach 10 bar. PEX is a flexible and durable material is also resistant to chemicals. Pipes made of PEX does not overgrow inside, they can freeze and subsequent unfreezing they do not collapse.
PEX – ABS – widely used for PEX fittings, products for the hull and pneumatic systems. The temperature, which can withstand the ABS ranges from -40 to +70 C and withstand the pressure of 15 bar. This material, characterized by resistance.
It should be noted that such properties as impact resistance manifested especially in the high content of butadiene in the ABS. Hardness, luster, rigidity – with styrene, and strength, heat resistance, hardness with acrylonitrile.
PVDF – for the manufacture of valves. The temperature can vary from -40 to +140 C and pressures as high as 16bar. Material resistant to radiation, chemical resistance, resistance to wear. In addition, resistant to ultraviolet.
PEX – a material is an insulator, solid, but it is worth considering that the chromium compound, N2SO4 and HNO3 are destructive to the PEX. To improve properties such as light and heat resistance of PEX added stabilizers. In addition to water use and PEX tubing for heating systems.
CPVC (chlorinated polyvinyl chloride), this material represents a modification of PVC. Because it produces PEX fittings, pipes. At a pressure of 16 bar, temperature washes range from 0 to-100C.
In addition, there is a modification of PEX, the material High strength and can withstand high temperatures.
It may be noted as polycarbonate, but it is used to spetsarmatury, thanks to its strength and hardness.
This material is inexpensive, it is absolutely safe, and economical.
To achieve high performance communication PEX tubing and low accident rate must be complied with the rules of operation, and before this assembly.
