ISO4427 standard HDPE dredge/mining pipe,welded with flanges at the both end, available in 6m or 11.8m length,customrized steel backing rings available,high quality at best wholesale price. Contact us for more details of our HDPE dredge pipe from SENPU PIPE.
SENPU PIPE High density polyethylene pipe(HDPE PIPE) takes special polyethylene as the raw material and be extruded by once-shaping technology from a plastic extruder. HDPE pipe can be applied to all dredging project such as river dredging and mine tailing dredging,especially to transport high wearing material. HDPE pipe is your ideal and economical choice for your dredging work.
Performance and Characteristics
※ Corrosion resistance: high resistance to attach from various types of chemicals,no electrochemical corrosion.
※ High toughness: fracture extension rate of HDPE 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 pipe is only 1/5 of steel pipe on the weight.
※ Easy to assemble or dismountable: The HDPE dredge pipe welded with flanges can be assembled or disconnected very easily.
※ Excellent flexible and resistance to scratches ability.
※ Good wear resistance, low wall friction coefficient, small flow resistance, excellent conveying ability.
※ Low system cost, less maintenance costs, can dramatically reduce the cost for the project.
※ Long service life.
※ Recyclable and environment-friendly: HDPE material can be reused, complete with the concept of efficient environmental protection which our state advocates
