Global HDPE & PVC pipe manufacturer — Exporting to 80+ countries
Industry-leading extrusion lines, injection presses, and fusion welders — the machinery behind every Puhui pipe.
Puhui’s daily output of HDPE and PVC pipe systems rests on three categories of production equipment: continuous extrusion lines for pipe, injection-molding presses for fittings, and fusion welders for fabricated assemblies.
Every line is paired with in-line gauges (laser diameter, wall-thickness ultrasonic, eccentricity scanners) and a sampling cell feeding our QA lab — meaning a defect is caught on the line, not at the customer site.
Single & twin-screw extruders, 20 mm – 2000 mm pipe diameters, SDR 7.4 to SDR 41.
Servo-driven presses for butt-fusion, electrofusion, and spigot fittings up to DN 800.
Butt-fusion welders DN 90 – DN 1600 plus electrofusion CNC controllers in-house.
Hydrostatic burst, MFI, oven-aging, density, dimensional comparator — all on-site.
Private labelling, color-keyed batches, drawing-based fittings, and certification packages available on request.
