Hardware & Machinery
HDPE welding machines (butt fusion, electrofusion, socket fusion) plus HDPE hollow and solid bars for jobsite pipe joining and machining.
HDPE Butt-Fusion Welding Machine
Manual (SPA series) and automatic (W series) butt-fusion welding machines for jointing PE / PP / PVDF pipes from DN63 up to DN1200 mm. Heated-plate butt fusion produces homogeneous, monolithic joints stronger than the parent pipe — the dominant jointing method for HDPE water, gas and mining pipelines. Compliant with ISO 21307 / DVS 2207 / ASTM F2620 welding procedures and ISO 12176-1 machine certification.

Electrofusion Welding Machine
Automatic multi-function electrofusion welding units for jointing PE and PP pipes through electrofusion fittings. Barcode scanner reads each fitting's welding parameters; the machine then regulates output voltage and timing with energy-output compensation for ambient temperature, ensuring repeatable, certified joints. Suitable for trenchless installations, gas networks where butt fusion is impractical, and remote service connections.

Socket-Fusion Welding Machine
Hand-held socket-fusion welding machines for small-diameter PP-R / PE / PB / PVDF plumbing and chemical-process pipework. Pure aluminium heating plate with electrostatic-spray finish; imported hydraulic power unit. Two welding ranges available — DN20-63 (residential plumbing) and DN63-160 (commercial / industrial). Commonly used for indoor PP-R hot/cold water plumbing.

Questions about our product range
Sizing, customisation, MOQ and documentation — the most common pre-quote questions.
How many product lines does Primepoly offer?
41 products across 6 categories: HDPE pipes (10), HDPE fittings (6), PVC pipes (7), PVC fittings (12), hardware & machinery (5), PP fittings (1). New SKUs are added when market demand justifies it — typically 2–4 per year.
Can I order a custom OD, SDR, colour or marking?
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.
What is the minimum order quantity (MOQ)?
Standard MOQ varies by product: roughly 1 ton for HDPE pipe, 500 kg for PVC pipe, and one full container for export orders. Custom MOQ is available for sample or pilot projects — contact our sales team for confirmation.
Do products come with documentation?
Every shipment includes the mill certificate, hydrostatic test report, certificate of origin and the relevant ISO 4427 / AWWA C906 / WRAS / NSF 61 compliance documents. SGS / BV third-party inspection reports are available on request at the buyer's cost.
Can I get free samples?
Yes for low-DN PVC fittings and pipe-fitting samples. For HDPE pipe samples we typically ship a 0.5–1 m offcut at our cost; the buyer covers DHL / FedEx airfreight. Email sales@primepolypipes.com with the spec you want to sample.
