Our product is suitable for use in water supply pipelines, mining pipelines, and pipelines for trenchless installation and rehabilitation, among other applications, within a temperature range of -25°C to 45°C. It is designed to accommodate water pressures ranging from 0.8 MPa to 2.0 MPa.


Blesson PVC-O pipes have half the wall thickness of traditional PVC pipes, making them the lightest in water supply systems and easy to install.
The thinner walls allow for a larger internal diameter, maximizing water flow capacity.
The smooth inner surface resists bacterial and algal growth, reducing energy loss and water delivery costs.
Blesson PVC-O pipes offer excellent resistance to crushing, cracking, and notch propagation, with outer wall damage not extending to the inner wall, minimizing failure risks.
1. PVC-O pipes and fittings are manufactured in a standard blue color, with the option to customize other colors based on customer specifications.
2. The internal and external surfaces of the pipes are smooth and uniform, free from significant scratches, cracks, dents, visible impurities, or any other surface defects that may impair the performance of the pipes.
3. The standard lengths of the pipes are 6 米, 9 米, 和 12 米, with custom lengths available upon customer request. All dimensions comply with the requirements of GB/T 41422-2022 “Oriented Unplasticized Polyvinyl Chloride (PVC-O) Pipes and Fittings for Pressure Water Transmission.

High-performance PVC-O Fittings, made from PVC-U via a specialized stretching process, offer high performance, long life, and lightweight properties. They replace traditional PVC-U and steel-plastic fittings in pressurized systems, costing 15%-30% less and providing significant economic benefits.
