Product Description
HDPE Dredging Pipe is used to transport sand, mud, gravel and slurry over long distances during dredging operations. It is far lighter than steel, easy to relocate as the dredge advances, and resistant to abrasion from solids and chemical attack from saline or contaminated water.
Advantages and Characteristics
1. Lightweight: about 1/8 the weight of steel pipe of equivalent size, drastically lower handling cost.
2. Floating capability: HDPE pontoon floaters in safety yellow or orange let pipes span open water without barges.
3. Strong abrasion resistance: thick-wall PE100 / PE4710 stands up to silica sand and gravel for years of service.
4. Long single-strip lengths: 11.8 m strips and butt-fusion joints minimise field welds and maintenance points.
5. Quick-couple flange ends: ductile-iron backing rings and stub-end flanges allow rapid connection and dismantling between sections.
6. Saltwater resistant: immune to galvanic corrosion in marine environments.
Typical Applications
1. Harbour and channel deepening — discharge lines from cutter-suction dredgers.
2. Land reclamation projects: pumping sand fill from offshore borrow pits.
3. River and lake desilting and ecological restoration.
4. Sand and gravel washing plants — tailings discharge.
5. Mining tailings disposal where lightweight, relocatable lines are required.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for HDPE / PVC pipe?
Standard MOQ varies by product — generally 1 ton for HDPE pipe, 500 kg for PVC pipe, and one full container for export orders. Custom MOQ is available for sample / pilot projects — contact our sales team for confirmation.
What is the typical lead time?
For stocked sizes, 7–10 days from order confirmation; for custom OD / SDR / colour, 25–35 days. Production capacity exceeds 2,000 t/month — large project orders are scheduled in batches.
Which certifications does Primepoly hold?
ISO 9001, ISO 4427, AS/NZS 4130, ASTM F714, AWWA C906, WRAS and NSF 61. Documentation accompanies every shipment, and third-party inspection (SGS / BV) is welcome at the buyer's request.
Do you offer OEM and private-label manufacturing?
Yes — we manufacture pipes and fittings to customer-specified OD, SDR, length, colour, marking and packaging. MOQ for OEM orders typically starts at 5 tons or one full container.
How are pipes packaged for export shipping?
Pipes are bundled with PE film / steel strap and stowed by length: short pipes (≤6 m) ship in 20'/40' containers; long pipes (>12 m) ship by break-bulk vessel or flat rack. Coil rolls are shrink-wrapped and palletised. Free OBL with shipping documents.
