UPVC S6.3 national standard pipeline Product Overview
UPVC S6.3 industrial piping is manufactured from high-purity rigid polyvinyl chloride, compliant with GB/T 10002.1 standards. It features nominal outer diameters ranging from 20 to 250mm, with an operating temperature range of -10°C to 45°C. The 20mm specification supports pressures up to 2.5MPa, making it an ideal choice for low-pressure industrial fluid transmission.
UPVC S6.3 national standard pipeline Key Features
Resists corrosion from 20% sulfuric acid and 30% sodium hydroxide solutions. Achieves flame retardancy B1 grade with an oxygen index ≥40%. Internal wall roughness of only 0.01mm reduces fluid resistance by 25% compared to steel pipes. Weighs one-sixth of steel pipes, boosting installation efficiency by 40%. Meets GB/T 17219 hygiene standards, balancing durability and cost-effectiveness.
UPVC S6.3 national standard pipeline Manufacturing Process
Premium UPVC resin with polymerization degree 1200-1600 undergoes twin-screw extrusion at 165-185°C, vacuum sizing (±0.2mm precision), segmented spray cooling at 22-26°C, and online inspection. Each pipe passes 1.8 times nominal pressure hydraulic testing before cutting and packaging.
