Self-anchored Ductile Iron Pipe

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 and having good flexural performance.

It can replace the function of the constraint block and realize the design of no constraint block. It is mainly used in cases 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 anti-slip.
