HDPE Dredge Pipe Manufacturers

HDPE dregde pipe

HDPE pipe has been more & more preferred & used by our customers for dredge works. The HDPE dredge pipes are assembled with flanges at the both ends. By using steel bolts/nuts to fix the the whole HDPE dredge pipe, it can be easily assembled or disassembled.

SUNPLAST HDPE dredging pipe has been a ideal replacement of steel pipe for dredging works, due to superior performance & characteristic that it has:

※ Corrosion resistance: high resistance to attach from various types of chemicals, no electrochemical corrosion, so HDPE dredge pipe can be used for sea water without worry about corrosion problem.

※ High toughness: fracture extension rate of HDPE dredging pipe, commonly more than 500%. As to the uneven settlement of the base, its adaptive ability is very strong, good aseismic performance.

※ Light weight: by comparing steel pipe, the HDPE dredge pipe is only 1/5 of steel pipe on the weight, less pipe floats be needed

※ Easy to assemble or dis-mountable: The HDPE dredge pipe welded with flanges can be assembled or disconnected very easily.

※ Excellent flexible and resistance to scratches ability: HDPE dredging pipe is more flexible than steel pipe, so less rubber hoses be required.

※ Good wear resistance, low wall friction coefficient, small flow resistance, excellent conveying ability: HDPE dredging pipe has a good toughness, smooth wall allows the pipeline has good wear resistance & high flow rate.

※ Low system cost, less maintenance costs, can dramatically reduce the cost for the project: HDPE dredge pipe is much lower price than steel pipe, at the same time more durable use when it is used for sea water.

※ Long service life: HDPE dredging pipe can service longer lifetime in sea water.

※ Recyclable and environment-friendly: HDPE material can be reused, complete with the concept of efficient environmental protection which our state advocates

SUNPLAST HDPE dredge pipe can be supplied from dn110mm to 1200mm, with various SDR ranges. The customers can always find the right pipe for their dredge work.

The steel flanges, which are assembled at both ends, can be drilled into EN1092 standard, or customized-made.

SUNPLAST HDPE dredging pipe is regularly provided in 5.8m or 11.8m length, which is suitable for container loading. Other length also available as per customer needs.

When HDPE dredge pipe is used for dredge work, it normally assembled together with dredge pipe floats & suction/discharging rubber hoses. The pipe floats provide sufficient buoyancy to support the whole dredging pipeline above the water, while rubber hoses can reduce wobble caused by sea wave.

SUNPLAST is a integrated provider of HDPE dredging pipe, dredge pipe floats & rubber hoses.

HDPE DREDGING PIPE

Dredge pipe floats

Dredge pipe floats are designed & manufactured in barrel shape that can absorb or reduce the energy from vessel collision of sea wave impacting. The dredge pipe floats consists two-halves, each halves can be placed on the HDPE dredge pipe, fixed by steel bolts & nust or bandages.

The dredge pipe floats are by rotational molding technology. One-time rotational molding made outer shell is made of LDPE or MDPE with high wear resistance & inside filled with high strength polyurethane closed-cell foam, which is free of water absorption.

SUNPLAST can provide various dimensions of dredge pipe floats for options, based on the size of HDPE dredge pipe that be used:

Floater I.D. （HDPE Dredge Pipe O.D.) (mm)	Floater O.D. (mm)	Floater Length (mm)	Thickness Of MDPE Shell (mm)	Net Buoyancy (kg/pcs)
