Oriented Polyvinyl Chloride(PVC-O) Pipe

There are many benefits to pipes and fittings made of PVC-U. They are a safe option for transporting drinking water, are lightweight, easy to handle, and affordable. Technical properties include high mechanical properties, high durability (min. 100 years for underground pipes), high chemical resistance and resistance to UV radiation.

Description of Oriented polyvinyl chloride(PVC-O) pipe

In 1970, York shirelm perial Plastics (Uponor) in the United Kingdom developed the PVC-U. In the early days, the "off-line" processing technology (two-step processing method) was used to extrude and cool the PVC-U pipe. The segments (thick blanks) are oriented within the mold by expansion to the desired dimensions by heat and pressure. PVC-O has extraordinary performance according to the experimental studies and practical applications. However, because of the "off-line" processing technology has low production speed and high equipment investment. It is difficult to use in mass production.

Later, it can be produced continuously beacuse of the orientate "in-line" during the extrusion process. The production process is a one-step processing method, on the pipe extrusion production line, the extruded PVC-U pipe (thick blank) is biaxially oriented by radial expansion and axial stretching, and then cooled and shaped to become PVC-O pipe. The production efficiency been improved and manufacturing costs reduced by the "in-line" biaxially oriented production process. Make it more competitive compare with other pipes.

PVC-O can be used in water supply pipeline, drainage pipeline, mine pipeline, trenchless laying and repairing pipeline, gas pipeline networks, etc.

PVC-O connection method include flexible interface, threaded fitting and flange connection.

Def pipeline is the ideal piping solution with the safty and reasonable price.

Advantages of Oriented polyvinyl chloride(PVC-O) pipe

• 1. It has impact resistance: The damage caused by the impact and collision of foreign objects is minimized during pipeline installation, water testing and even operation.​​
• 2. It has super high strength: The wall thickness of PVC-O pipe is only half of ordinary PVC-U pipe while strength is 4 times.​​
• 3. Excellent elasticity: The deformation of the pipe endured in the diameter direction reaches 100% of the inner diameter. When the pipe is extruded, it can restore to its original shape, thereby minimizing the risk of damage caused by sand and gravel extrusion or mechanical impact during construction. At the same time, the excellent toughness makes the PVC-O pipe suitable for the laying of S-shaped pipelines.​​
• 4. It has good low temperature brittleness resistance: The ability to absorb shock does not change much even under -25 ℃. Make sure it can be used in more areas.
• 5. Excellent anti-cracking ability: PVC-O pipe is not sensitive to gaps, and the mesh pipe wall structure can effectively prevent the extension of cracks and scratches, and the damage points caused by the outside world to the pipe body will not expand.​​
• 6. Excellent water hammer resistance: The wave speed is much lower than traditional pipes and 4 times lower than cast iron pipes, which means that the water hammer caused by changes in water pressure and water volume is reduced, thereby reducing or even eliminating the opening and closing of water. At the same time, when the water network is running, it also forms protection for various parts of the water network.​​
• 7. Convenient connectivity: The PVC-O pipe adopts flexible connection, which is simple and fast in construction and installation, make sure the joint will not shift after the pipeline is installed. The pipeline has good water tightness and less leakage.​​
• 8. It is environmentally friendly and energy-saving: The wall of the PVC-O pipe is only half of the traditional plastic pipe, which increases the inner diameter and the cross-sectional area of ​​water delivery. The excellent production equipment and technology make the inner wall of the PVC-O pipe much larger than the metal pipe. The PVC-O pipe with the same outer diameter can increase the water flow by 15-40% compared with the traditional pipe.​​
• 9. It has excellent hygienic performance: The realization of the molecular biaxial orientation technology of PVC-O pipe is based on high-quality raw materials. No coating is required inside and outside the pipe since it's corrosion-resistant. There is no migration of other substances to the water during the delivery, water quality remains unchanged during transportation.
