When considering durable piping solutions for residential, commercial, and industrial projects, UPVC (Unplasticized Polyvinyl Chloride) pipes and HDPE (High-Density Polyethylene) pipes have become the preferred choices worldwide.

Ductile iron pipe (DIP) has become the backbone of modern water distribution and wastewater management systems, thanks to its exceptional strength, durability, and cost-effectiveness. Designed to withstand high pressure and environmental stress, ductile iron pipes are widely used by municipalities, utility companies, and construction firms around the world. For decades, this material has consistently proven itself as the optimal choice for infrastructure projects requiring reliability and longevity.

The company focuses on the research, production and sales of ductile iron pipes. It can produce 26 types of centrifugal ductile iron pipes with diameters ranging from DN80 to 2600 mm, and also has the capability to provide supporting products such as mineral resources, casting pipe fittings and casting gaskets. It is one of the manufacturers in China that can provide a wide range of ductile iron pipe products.

Ductile iron pipes are widely used in water and gas transmission due to their excellent strength, toughness, and cost-effectiveness. To withstand the corrosive nature of different conveyed media and environments, their inner walls are protected with various lining materials. Selecting the appropriate lining is crucial.

The core sealing of a gate valve relies on the tight fit between its wedge or parallel disc and the valve seats. In theory, when the disc is fully lowered, it should block the fluid passage. However, in practice, solid particles in the fluid (such as sediment, welding slag, or scale) can easily become trapped between the disc and the seat sealing surfaces. Even very small particles can prevent the disc from fully seating, leaving microscopic gaps on the sealing surface and causing leakage. This phenomenon is particularly common in pipelines with unclean fluids.
