HDPE Mining Pipe
Heavy-wall PE100 for slurry, tailings and dewatering lines. Wear allowance on the wall, flanged transitions to pumps, and couplers for field repair.
Tell us the size and quantity — price, lead time and loading plan back in one working day
Dial in the pressure class first, then the diameter. If you are unsure, send the working pressure and we will recommend the SDR.
SDR9 to SDR17 — how much wall you actually need
Slurry lines are usually sized on velocity and wear, not only pressure. Lower SDR buys more abrasion allowance at the cost of weight and price.

e = OD ÷ SDR, mass at 955 kg/m³ (calculated). Confirm against the ISO 4427-2 / ISO 4437 thickness table before publishing; OD above 630 mm and SDR33/41 on request.
Sizing notes for slurry lines
- Keep velocity above the settling threshold but below the abrasion spike
- Add one SDR step of wall for high-solids tailings
- Flanged spools at pump connections simplify replacement
- Spare couplers and a short repair section travel with the order
What ships with the order
- Mill certificate with resin batch and lot number
- Wall thickness and weight check per lot
- Fusion parameter chart by diameter
- Packing list per item for mixed containers
Send flow, solids and head
Tell us the pump pressure and the run length — we will propose wall and jointing.
Questions on this product
How do I choose the wall for a slurry line?
Start from velocity and solids, then add wall for wear. Send the flow rate, solids content and head and we will come back with an SDR recommendation.
Do you supply flanged sections?
Yes — flanged spools and stub ends can be fused or supplied loose for site assembly.
Is hydrostatic testing available?
On request, per lot, with the report attached to the shipping documents.
What is the lead time?
[To confirm — heavy-wall runs usually need a production slot.]
