The biaxially oriented PVC pipe extrusion line mainly includes: feeding system equipment, PVC-O pipe extruder, vacuum sizing box, spray cooling tank, traction machine, cutting machine, expanding machine, etc.

PVC-O pipe, the full name is biaxially oriented PVC pipe (Biaxially Oriented PVC Pipe). PVC-O pipe is based on pure formula PVC-U pipe. PVC-O pipe is an innovative pressure-bearing pipe processed by axial and circumferential biaxial stretching process in a specific state of high elasticity.
Compared with traditional pipes, PVC-O pipes show significant advantages. During the biaxial stretching process, the material undergoes subtle changes at the microscopic level. The molecular chains that were originally linear in structure are rearranged and transformed into a stretched mesh structure. This structural transformation fundamentally strengthens the material properties, significantly improves the strength of the pipe, and can withstand greater pressure; the toughness is enhanced, effectively resisting external impact and reducing the risk of damage; the stress cracking resistance is optimized, and the structure remains intact under complex stress environments, greatly extending the service life of the pipe.
With these outstanding properties, PVC-O pipes stand out. As a new generation of pressure-resistant water supply and drainage pipes, they not only meet the current stringent engineering needs, but also show rapid development momentum in both domestic and foreign markets, injecting strong impetus into the optimization and upgrading of water supply and drainage systems, and becoming the focus of industry attention.
PVC-O pipes are primarily used for the transportation of potable water, irrigation, water conservancy projects, landscaping, drinking water supply in rural areas, fire protection systems, factories and mines, chemical corrosion prevention, sewage systems, reclaimed water, and more-specifically for conveying high-pressure water.

Different target markets have different demands for PVC-O pipe extrusion line. For example, the European market prefers to use it in the field of high-pressure water pipes, which have extremely high requirements for the pressure resistance, dimensional accuracy and long-term stability of the pipes. The Asian market focuses on agricultural irrigation pipes, focusing on the cost-effectiveness, corrosion resistance and ease of laying of the pipes.
