PVC Pipes

Product Overview

DN 15–400mm, PN 16, blue/gray color. Heavy-wall industrial-grade UPVC pipe for chemical, process, and industrial water systems. Conforms to GB/T 4219.1-2008.

The S6.3 heavy-wall series carries a full PN16 rating across DN15–400 in blue or gray, giving industrial buyers one dimensionally consistent pipe family for process water, chemical dosing and corrosive utility lines where thin-wall plumbing pipe cannot hold the pressure.

Key Features

Full PN16 Rating: Thick S6.3 series walls safely handle continuous 16 bar working pressure for industrial duty.
Excellent Chemical Resistance: Withstands acids, alkalis, salts, and most industrial chemicals without corrosion or scaling.
Blue/Gray Color Coding: Clear visual identification of industrial lines reduces cross-connection risk on site.
Smooth Bore: Low friction inner surface minimizes pressure loss and resists scale build-up over decades of service.
Solvent Cement Jointing: Simple, fast, and leak-proof connections using standard UPVC adhesive.
Widest Industrial Size Span: DN15 instrument branches through DN400 process headers in one S6.3 series, so an entire plant can be piped with matching fittings and pressure class.

Production

Manufacturing Process

Manufactured on high-speed twin-screw extrusion lines with vacuum calibration and online laser diameter monitoring. Each batch is hydrostatically tested to guarantee the full PN 16 pressure rating.

Quality Control & Testing

Every lot is hydrostatically tested at 1.5× rated pressure per ISO 1167; heavy-wall dimensions are 100% checked against S6.3 tolerances, with additional Vicat softening, impact and chemical-resistance spot tests for industrial orders. Mill certificates and batch records are supplied on request.

Raw Material

Industrial-grade virgin UPVC compound selected for broad chemical compatibility and lead-free stabilization; its non-rusting, non-scaling structure is suited to aggressive plant environments and carries a 50-year design life at rated pressure.

Applications

Industrial process water and chemical dosing lines — PN16 headers and metering branches in water-treatment and manufacturing plants, color-coded blue/gray to separate process from utility services.
Electroplating, pickling and wastewater treatment piping — acid- and alkali-resistant runs through plating shops and neutralization units where steel would need repeated replacement.
Cooling water and compressed air systems — smooth-bore PN16 loops feeding chillers, cooling towers and low-pressure air distribution with low friction loss.
Food and beverage plant utility lines — lead-free, scale-free pipework for rinse water, CIP ancillary lines and service fluids around production halls.
