Large Diameter HDPE Dredging Pipe, Wear Resistant Anti-Corrosion HDPE Dredge

Large Diameter HDPE Dredging Pipe, Wear Resistant Anti-Corrosion HDPE Dredge Pipeline For River Dredging, Sea Reclamation, Sand Slurry Conveying

Product Description:

HDPE Dredging Pipe is a professional thermoplastic pipeline specially developed for solid-liquid mixed slurry transportation in all kinds of dredging engineering projects, manufactured from high-performance high-density polyethylene raw materials via one-step extrusion molding process. Different from traditional steel pipes, cast iron pipes and PVC pipes commonly used in fluid delivery, this series HDPE dredge pipe is optimized targeting the harsh working conditions of long-distance sand pumping, mud conveying, silt drainage and sediment transportation. It can continuously convey sand, gravel, mud, silt, seawater mixed sediment and abrasive granular medium for a long time under underwater buried laying, floating on water surface, offshore floating installation and land trench laying scenarios. Our factory supports customized caliber, wall thickness, single pipe length, connection methods and anti-ultraviolet surface treatment according to the actual construction parameters of overseas dredging contractors, dredging engineering companies and port construction enterprises.

Core Product Features:

• Ultra-high abrasion resistance: Inner wall has smooth low-friction structure, wear resistance is 3-5 times higher than carbon steel pipe, effectively resist scouring of sand, stone and hard sediment particles
• Superior anti-corrosion & anti-scale performance: HDPE material will never rust, immune to seawater corrosion, acid and alkali sewage, sediment chemical erosion; inner wall not easy to adhere mud and dirt, no pipeline blockage during long-term slurry delivery
• Light weight & great flexibility: Only 1/8 weight of steel pipe with same specification, easy hoisting, transportation and on-site splicing; good toughness can adapt to riverbed settlement, terrain fluctuation without cracking
• Impact & low temperature resistant: Keep stable mechanical property under -40℃~60℃ environment, no brittle cracking in cold coastal and northern waters
• Smooth inner wall & low flow resistance: Low hydraulic loss, save pump power consumption, improve slurry conveying efficiency and reduce operating energy cost
• Safe non-toxic material: Food-grade qualified HDPE raw material, no precipitation harmful substances, applicable for freshwater river ecological dredging projects
• Flexible diversified connection: Flange connection, hot melt butt welding, rubber hose clamp connection available, tight sealing, zero leakage for underwater delivery
