About Puhui
Built Around Proven Machinery
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.
Key Equipment Families
HDPE Extrusion
Single & twin-screw extruders, 20 mm – 1800 mm pipe diameters, SDR 7.4 to SDR 41.
Injection Molding
Servo-driven presses for butt-fusion, electrofusion, and spigot fittings up to DN 800.
Fusion Welding
Butt-fusion welders DN 90 – DN 1600 plus electrofusion CNC controllers in-house.
QA Test Rigs
Hydrostatic burst, MFI, oven-aging, density, dimensional comparator — all on-site.
