High quality corrosion resistant UPVC water supply and drainage pipe manufacturers wholesale customization
UPVC pipes Features:
Excellent corrosion resistance
Chemical stability: UPVC (unplasticized polyvinyl chloride) can withstand strong acids (such as sulfuric acid and hydrochloric acid with a concentration of ≤30%), strong alkalis (such as sodium hydroxide solution), salts and most organic solvents (such as ethanol and acetone), and is widely used in chemical, electroplating, sewage treatment and other fields.
Anti-corrosion mechanism:The molecular structure is tight, no plasticizer is precipitated, and the chemical medium is blocked from penetrating;
The stabilizer (such as calcium zinc complex) neutralizes the HCl produced by the decomposition of the material to prevent autocatalytic degradation.
Case: After a chemical plant replaced stainless steel with UPVC for hydrochloric acid pipelines, its service life was extended from 3 years to 15 years.
Lightweight and high installation efficiency
Weight advantage: The density is only 1.38-1.55 g/cm³, which is 1/5 of the same specification steel pipe and 1/10 of the cast iron pipe, reducing transportation and hoisting costs by 30%-50%.
Installation technology:Use rubber ring socket connection or adhesive bonding, no welding or flange connection required;
The construction speed is more than 3 times that of metal pipes (for example, the installation efficiency of DN100 pipes can reach 20 meters/hour).
Flame retardant and fire safety
Flame retardant grade: Oxygen index ≥45%, reaching UL94 V-0 standard, low smoke emission during combustion (smoke density level ≤15), suitable for fire prevention scenes such as subway tunnels and hospitals.
Safety features: No combustion-supporting gas is released at high temperatures, and the spread of fire can be effectively delayed in case of fire.
Extra-long service life
Anti-aging performance: By adding ultraviolet absorbers (such as carbon black, titanium dioxide), the outdoor service life can reach more than 30 years (ordinary PVC is only 8-10 years).
Creep performance: 50-year long-term hydrostatic strength retention rate >80% (ISO 9080 standard), maintenance-free buried engineering.
Hygiene and environmental protection
Drinking water safety : Passed NSF/ANSI 61 certification, smooth inner wall (Ra≤0.2μm), microbial attachment rate is 90% lower than that of metal pipes, suitable for direct drinking water systems.
Recyclability : Waste can be crushed and granulated, with a recovery rate of >70%, in line with EU RoHS environmental protection standards.
Excellent insulation performance
Electrical insulation : Volume resistivity ≥1×10¹⁴Ω·cm, withstand voltage strength ≥25kV/mm, can be directly used for 10kV cable protection sleeves.
Anti-electromagnetic interference : Shielding coefficient ≤0.5, suitable for substations, communication base stations and other scenarios.
