Product Description
HDPE Hollow Bar (also called PE bar stock with through-hole) is a thick-wall extruded hollow profile used as raw material for machining custom valve bodies, bearing housings, sleeves and chemical-process components. PE100 grade gives chemical resistance and dimensional stability comparable to high-end engineering polymers at a fraction of the cost.
Advantages and Characteristics
1. Through-hole reduces machining time vs. solid bar by avoiding deep boring.
2. PE100 raw material — same properties as our pressure pipe.
3. Available in OD 50 mm – 500 mm with various wall thicknesses.
4. Stress-relieved during slow-cool to minimise warpage during turning.
5. Custom OD/ID combinations on request for project-specific machining.
Typical Applications
1. Machined valve bodies, ball-valve seats and end-fittings.
2. Bearing sleeves and dock-fender bushings.
3. Custom flange backers and stub-end blanks.
4. Wear-resistant components in dredging and slurry equipment.
5. Replacement parts for chemical plants where weld-fabricated PE is impractical.

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.
