Dredging Pipeline

Julong dredging pipeline including HDPE pipe,Floaters,Rubber Hose,Self-Floating Rubber Pipe and relative fittings, we have own customized factory to make Julong Dredging Pipeline permanently, which could confirm stable delivery time, good quality control and beautiful price.

The weight of HDPE pipe is light, The pipes are connected with flanges, which makes the assembly, disassembly and transportation easier. The HDPE pipe has good flexibility, It doesn't break after folding, extruding, or internal or external force impact. The bending degree of 4 to 8 pcs of pipes can be 360 degrees. It is of good resistance of storm and waves. The HDPE pipe has good wear-resistance, The material is of high corrosion resistance to be able to float in sea water for 50 years. Also it is uvioresistant, anti-aging and it can be used for 5 to 8 years according to the amount of sediment.

The shell of polyethylene floaters is made of middle density polyethylene with excellent toughness. The inner part is filled with high-strength polyurethane. It has reasonable structure and excellent performance, excellent toughness, high impact resistant performance, especially suitable for offshore construction. Light-weight, convenient for assembly and transportation, low transportation cost. Corrosion resistance, anti-aging, long working life.



When the rubber hose is tested under 1.5 times of the specifified operating pressure, there should be no abnormal situations like leakage or partly gas bubbling. When the deformation test of rubber hose is taken, its length and outer diameter change rate should meet the standard specififications.

Self-Floating Rubber Pipe has the features of anti-storm, corrosion resistance, automatic flfloating performance, high operating pressure, long work life and quick assembly etc. With special foam flfloating layer, the percentage above water is no less than 25%. The bending angle at work varies from 0 degree to 50 degree. With simple transportation and quick assembly, it is a fabulous replacement pipe for traditional discharge pipe.
