REHOME PVC-U pressure pipes and fittings are manufactured from high-quality raw materials and processing additives, representing the core product of the company's mature technology. ISO 1452 is the international standard for unplasticized poly(vinyl chloride) (PVC-U) solid-wall piping systems, covering pressure water supply as well as buried and above-ground pressure drainage and sewerage.
Compared with cast iron pipes, PVC-U pipes offer an incomparable long service life and superior corrosion resistance. During construction, they are lightweight, making handling, installation, and connection easy. They are widely used in civil construction, drainage and sewage, chemical drainage and sewage, rainwater, and other fields.
Product Advantages
1. International Standard Certification
ISO 1452 is the international standard for PVC-U pressure pipes. Compliance ensures that the product meets the technical requirements for pressure water supply pipelines in most countries and regions worldwide, making it suitable for international engineering projects.
2. Excellent Pressure Resistance
With explicit pressure ratings (PN6-PN25), the pipes can withstand working pressures up to 25 bar, suitable for municipal water supply mains and building water supply systems under pressure.
3. Superior Corrosion Resistance
Unlike cast iron pipes, PVC-U pipes do not rust or corrode, offering excellent resistance to acids, alkalis, salts, and other chemicals—particularly suitable for chemical drainage/sewerage and coastal applications.
4. Long Service Life
Under normal operating conditions, PVC-U pipes have a design service life of up to 50 years, with extremely low maintenance costs.
5. Lightweight and Easy to Install
Specific gravity is only 1/5 that of cast iron. Handling is convenient, and installation workload is only about 1/2 that of steel pipes, significantly shortening construction time and reducing labor intensity.
6. Low Fluid Resistance
The smooth inner wall and low surface tension prevent scale buildup, providing a fluid conveyance capacity 43.7% higher than cast iron pipes.
