HDPE Disadvantages of HDPE Pipe and fittings manufacturer
Flanged HDPE pipe is made from wear resistant HDPE mixed with anti-UV material by extrusion molding technology.Shandong Xincheng Pipe Co., Ltd. is a professional manufacture of dredging HDPE pipes with 10years up experiences. HDPE pipes have exceptional properties such as corrosion resistance and light weight that makes them the best choice for dredging contractors.
Structure and Connection of Dredging Connection HDPE Pipe With Bolts,Nuts and Gaskets
1. Enlarged end, or flare end some people call, No welding required.
2. Nodular cast Iron inserts at end to protect it from deformation,breaking and leakage
3. Loose flang rings (carbon steel, galvanized) at both ends
4. Rubber gasket in between when two pipes are connected by bolts and nuts.
