Ductile Iron Pipe

The product categories of ductile iron pipes and fittings mainly include: water supply pipes, drainage pipes, thermal pipes, polyfluoroester lined pipes, argon resin lined pipes, epoxy ceramic lined pipes, PE lined pipes, zinc-aluminum alloy pipes, jacking pipes, drag pipes, self-anchored pipes, sewage pipes and matching pipe fittings.

Zinc plus infrared anti-corrosion coating and high alumina cement internal anti-corrosion coating have good wear resistance and can handle special soils and transportation media. The main application areas are municipal sewage pressure pipe networks with high anti-corrosion requirements. Sewage treatment plants have certain requirements for pressure resistance, and the media contains polyphenols and cyanide, these corrosive substances may harm the industrial sewage pipe network system.

The emergence of horizontal drill rod technology avoids road excavation and damage to other underground pipelines, reducing users' trenchless costs. At the same time, underground pipelines have less impact on traffic and the environment. In addition, it can run underground. In recent years, it has been widely used in the construction of underground pipelines such as municipal, industrial, and electric power. Horizontal drill rods are suitable for medium and small diameter ductile iron pipes. Standards: ISO2531, EN545, EN598. Category: Class K, Class C Connection method: Drag ductile iron pipe Range: DN80-DN2600 Length: 8.15 meters, 6.0 meters, 5.7 meters.

Pipeline jacking is mainly used in special construction projects. Pipelines need to cross obstacles such as roads, railways, rivers, and ground buildings. It is not allowed or difficult to dig trenches on the ground at the construction site.
The use of trenchless technology has been recognized by the majority of users and has solved some construction problems encountered in special projects.

The self-anchored pipe adopts a special mechanical design to weld the ring to the socket end to achieve reliable anchoring performance, while retaining the flexibility of the joint, with good flexural performance, which can replace the function of the constraint block and realize the design without constraint blocks. It is mainly used in situations where space, time or economic conditions are not suitable for setting restrictive blockades; there is a certain foundation settlement, or the slope of the pipeline laid on the ground exceeds 20% or the slope of the underground pipeline exceeds 25%. The axial stress at the end of the sleeve is transmitted to the sleeve through the sleeve retaining ring, flange, bolts, etc., thereby realizing the transmission of axial stress and making the interface have

The GT type interface is shown in the figure below. Its sealing principle is similar to that of the T type. As the internal pressure of the pipeline increases, the closer the contact surface between the rubber ring sealing cover and the socket is, the better the sealing effect. Standard: ISO2531, EN545, EN598 Category: K, C Type Joint type: GT type Joint range: DN80-DN2600 Length: 8.15 meters, 6.0 meters, 5.7 meters, can be customized according to customer requirements Application: drainage of water supply projects, sewage irrigation, water pipelines, etc. Internal coating: Portland cement mortar lining; sulfate-resistant cement mortar lining; high-alumina cement mortar; fused epoxy coating; polyurethane lining
