At present,There is 2 design of HDPE dredging pipe:
One design is HDPE dredging pipe with flange stub and steel flange for connecting between pipes.
Another design is HDPE dredging pipe with the steel ring inside the neck in China.
The disadvantage of HDPE dredging pipe is the joint part will be rasily broken when the pipe is working for a long time.so we designed a new kinds of pipe joint instead of HDPE flange stub and steel flange.we add the steel ring inside the neck to prevent the broken when the pipe working for a long time,The new design enables the pipe more than 50 years life and have a big prevent in dredging project.
The attached pictures are the HDPE dredging pipe with flange stub and steel flange and HDPE dredging pipe with steel ring inside the neck.
