Steel skeleton rubber ring pre-disposed PVC-O pipe and straightening and flaring forming process thereof
By using a straight flaring molding process for pre-installed PVC-O pipes with steel-reinforced rubber rings, the problems of unstable rubber ring assembly and poor flaring compatibility in PVC-O pipes have been solved, thereby improving sealing reliability and yield, making it suitable for high-pressure pipeline projects.

AI Technical Summary
The existing rubber ring assembly method for PVC-O pipes is unstable, resulting in poor sealing reliability. The traditional flaring process is also poorly adaptable, leading to joint leakage and low yield.
The PVC-O pipe with pre-installed steel-reinforced rubber ring is adopted. Through the flat flaring pre-forming process and the integrated pre-installation of the steel-reinforced sealing rubber ring, combined with the continuous automated production of a special flaring forming machine, the rubber ring is accurately positioned and the sealing reliability is achieved.
It improves the pull-out resistance and sealing performance of the interface, simplifies the installation process, increases the yield and service life, adapts to complex working conditions, and reduces construction costs.
