PP-R pipe is a new generation of environment-friendly construction material developed in 1990s. Besides plastic pipe merits, such as lightness, corrosion resistance, anti-deposition and long service life, PP-R pipe also have some new advantages, like hygienism, heatresistant, material recycled. In the meanwhile, lower coefficient of heat conductivity can help for energy conservation. The usage of thermosol binding technique can make the process of installation very convenient.

Chlorinated polyvinyl chloride (CPVC) is a unique polymer after polyvinyl chloride chlorination. Ordinary PVC molecular chlorine content is 45%, the chlorinated polyvinyl chloride (CPVC) molecules chlorine content is about 64% to 68%, up tomore than 70%. CPVC tensile capacity is higher than the UPVC, PP, PP - B, PP - R H, PB, HDPE, PE, PE - X RT, etc.

The main raw material of PVC-U piping network is PVC resin, which is added moderate stabilizer, lubricant, fillers, and toner. After the process of mixing, extrusion, sizing, cooling, and cutting, the PVC-U pipe can be made. The PVC-U fittings are made by injection.
The PVC-U material has very good chemical properties and physical property, which can suit for most of the normal fluid delivery conditions. This series of PVC-U drainage pipes and fittings can match the standard ASTM D2665.

This series of fittings can match the BS threaded standard – BS EN 10026-2 and BS 21.

This series of fittings can match the standard TIS 1131. This series of pipes can match the standard TIS 17.

High quality valves were supplied by WIMI, which valves made by qualified raw materials, were produced under strict production flows control and must be passed by strict test of quality.
Quality inspection for key components are carried out, including body processing, valve core processing, and component surface
fine machining processing. Technical test fixtures are designed by ourselves, and used to check the function for valves one by one.

As the series of PVC-U SCH80 piping network products for water supply and drainage with mature technology, pipes and fittings of PVC-U are one of the largest outputs for plastic products in the world, which already had been used widely both at home and abroad.
For WIMI PVC-U SCH80 water supply piping network, the raw materials and finished products are both match or exceed the relative standards.
