As one of the earliest manufacturers of PP-R pipes in China, we put every effort into product research and development.

Using raw materials, equipment and manufacturing technology imported from Germany, all of our pipes and related fittings meet DIN industrial standards set by that country.

With pipes in diameters from 20 to 160mm available in 4 pressure grades, 3 colors and nearly 300 specifications, these products are marketed under our proprietary "SD" brand.
