1. PVCO Pipes Performance
The pipes are smooth, even inner and outer surfaces, free from noticeable scratches, cracks, dents, visible impurities, or other surface defects that may impair performance.
2. PVCO Pipes Features
-
High impact resistance and compressive strength
PVC molecular chains are distributed in a mesh after biaxial stretching, which has strong impact resistance and pressure resistance. In the event of crushing or mechanical accidents, it can immediately return to its original state. The pipe is more flexible, easy to bend, within a certain bending radius, S-shaped laying can be carried out according to the terrain.
-
Long service life
Tianyuan PVCO pipe adopts biaxial orientation reinforcement technology, which maintains excellent performance in high-pressure water transmission environments. With a design service life exceeding 50 years, they significantly outperform ordinary PVC and metal pipes.
-
Excellent hygiene performance
The superior stretching process of PVCO results in thinner pipe walls, larger inner diameters, and smoother inner surfaces compared to traditional plastic pipes, making scaling and bacterial adhesion significantly more difficult.
-
Good corrosion resistance
Tianyuan PVCO pipe exhibits excellent corrosion resistance due to its unique material structure and process technology. It also does not require any special protection or coating, which can save costs.
-
Easy construction and installation
Tianyuan's PVCO water supply pipes are lightweight, only a small amount of manpower is needed to easily and quickly handle, and the installation of Tianyuan PVCO pipe system only need wire tightener, strapping, and other small tools.
3. Customization
-
Colors
High performance PVCO pipes and durable PVCO fittings are manufactured in standard blue color, but other colors can be produced upon agreement between the supplier and the customer.
-
Lengths
Standard PVCO pipe lengths are 6m, 9m, and 12m, though custom lengths can be negotiated. All other dimensions comply with GB/T 41422-2022 "Oriented Unplasticized Poly(Vinyl Chloride) (PVCO) Pipes and Fittings for Pressure Water Supply.“

01.What is PVC-O pipe?
PVC-O (Oriented PVC) pipe is an advanced plastic pipe made by biaxially stretching PVC to align its molecules, significantly enhancing strength and durability. Compared to traditional PVC, it offers higher pressure resistance, thinner walls, and longer lifespan (typically 50+ years), making it ideal for water supply and infrastructure projects.
02.Why is PVC-O environmentally friendly?
Compared to conventional pipes of the same nominal diameter, Tianyuan PVC-O require less PVC material yet maintain superior strength. Additionally, Tianyuan pipes ensure lower energy consumption throughout their entire lifecycle—from raw material extraction and manufacturing to operational use. By optimizing material efficiency and reducing energy demand, they offer an eco-friendly solution. After milling and processing, the recycled material can be repurposed for manufacturing various plastic applications with lower technical specifications, further enhancing sustainability.
03.What pressure classes and sizes are available?
We offers a comprehensive range of sizes and pressure ratings to meet various project requirements. Our product line includes different grades,such as PVCO pipe Grade 400,PVCO pipe Grade 450,PVCO pipe Grade 500. Please contact us for our detailed product catalog.
04.How does the jointing system work? Is it reliable?
Our pipes primarily use a simple, push-on joint system. This design allows for fast installation without the need for complex tools, welding, or chemicals. The joint is designed to be flexible, accommodating minor ground movements while maintaining a perfect, leak-free seal, ensuring long-term reliability.
05.Where can I get technical support or product specifications?
You can request our full technical documentation and product catalog by contacting us directly through our website or sales team. Our engineering team is also available to provide professional technical support for your specific project needs.
