PVC-O Technology Grades

PVC-O pipes have three most commonly used material grades

MRS Class	Temperature (°C)	Hoop Stress (MPa)	Time (h)
PVC-O 400	20 °C	52 MPa	10 h
PVC-O 450	20 °C	60 MPa	10 h
PVC-O 500	60 °C	65 MPa	10 h

How Molecular Orientation Works

The science behind PVC-O technology

1

Raw Material

PVC compound pellets are prepared with specific additives

2

Extrusion

PVC compound is extruded into a pipe billet at controlled temperature

3

Orientation

Biaxial molecular orientation aligns PVC molecules in circumferential and axial directions

4

Finished Pipe

High-performance PVC-O pipe with superior mechanical properties

The molecular orientation process reorganizes the randomly distributed PVC molecules into an oriented structure. This biaxial orientation dramatically improves the pipe's mechanical properties: tensile strength, impact resistance, and crack propagation resistance are all significantly enhanced compared to conventional PVC-U pipes.

Pipe Material Comparison

PVC-O vs PE vs PVC-U pipe parameters

On our homepage, the performance advantages of PVC-O pipes compared to other pipes have already been listed. Now, let's take the Dn315-PN16 pipe as an example to illustrate the economic advantages that PVC-O pipes have over other types of pipes. This is also the advantage of the PVC-O technology that sets it apart.

Category	PVC-O 500	PVC-U	PE100
Raw materials	PVC	PVC	PE100 (Expensive)
Pipe wall thickness	7.7 mm	9.7 mm	28.6 mm
Pipe weight	Light	Medium	Heavy
Based on the price of the raw materials and the weight of the pipes, it can be concluded that the PVC-O technology can give you an extraordinary competitive edge in the pipe industry.

What Our Customers Say

World-leading PVC-O technology empowering manufacturers across regions

Customer testimonials shown are representative examples based on typical project feedback.

“

Licensing Webon's PVC-O 500 technology gave us regional leadership in large-diameter high-pressure pipes. Our yield rates for DN450+ at 2.0 MPa far surpass any competitor — the technology literally created our market position.

Khalid Al-Mansouri

Technical Director

“

We started with PVC-O 400 technology and progressively upgraded to 450 and 500. Webon's technical guidance throughout was comprehensive — from installation to commissioning and ongoing training. The full-grade coverage let us scale without changing suppliers.

Andrei Popescu

CTO

“

The joint venture model worked perfectly for us. Webon brought the technology and equipment, we brought local market access. Together we built a PVC-O plant that now supplies the entire country. The cooperation model is genuinely win-win.
