China Detect potential pressure surges in advance to trigger timely relief. Manufacturer, Supplier, Factory

In an era where municipalities and engineering firms face immense pressure to balance cost, durability, and environmental impact, the selection of piping material is a critical long-term decision. For decades, one material has consistently demonstrated unparalleled performance in demanding applications: Ductile Iron Pipe (DIP).

​Beneath our cities' streets lies an unsung hero of urban development - ductile iron pipe. This remarkably durable material has quietly revolutionized water distribution systems since its introduction in the mid-20th century, offering an ideal balance of strength and flexibility that traditional cast iron couldn't match.

The classification of ductile iron pipes first depends on their joint connection types, which directly determine installation methods and engineering adaptability. The most common flexible push-on joints (such as Tyton joints) utilize compressed rubber gaskets to achieve self-sealing, allowing post-installation angular deflection (typically 3-5 degrees) to accommodate ground settlement or thermal movement. Another type, mechanical joints (like K-type or Fastite joints), employ bolted gland rings to compress wedge-shaped gaskets, providing higher sealing integrity suitable for pump station valve connections requiring frequent maintenance. Flanged joints feature steel flanges cast or welded to pipe ends, creating rigid connections via high-strength bolts, specifically designed to withstand high-pressure thrust or interface with industrial equipment.

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.

PE pipes are flexible, freeze-resistant, and ideal for fuel/solvent transport or buried installations, while uPVC pipes are rigid, low-cost, and suited for cold-water plumbing/drainage but brittle in sub-zero temperatures.
