Composite plastic pipe

Abstract

Provided is a composite plastic pipe. An outer layer is a PP-R pipe body, a wound layer is arranged on the inner wall of the PP-R pipe body and is formed by a high-strength yarn wound in the PP-R pipe body, strength and rigidity of the plastic pipe are enhanced, high-temperature and pressure resistance of the pipe is improved, the service life of the plastic pipe is prolonged, the plastic pipe has good shock resistance, and superiority of the composite plastic pipe is fully embodied.

Description

technical field [0001] The invention relates to a composite plastic pipe. Background technique [0002] After long-term struggle and opening up to the world, China's plastics industry has formed a relatively complete industrial system and has become a basic material industry that keeps pace with steel, cement, and wood. As a new type of material, its application fields have far exceeded the above three. Since the entry of this material into the 21st century, China's plastics industry has made remarkable achievements and achieved a historic leap. As one of the pillar industries of the light industry, the plastics industry has maintained a growth rate of more than 10% in recent years. While maintaining a relatively fast development speed, the economic benefits have also improved. The total output value of enterprises above designated size in the plastic products industry ranks third among the 19 major industries of light industry, achieving a product sales rate of 97.8%, whic...

AI Technical Summary

Problems solved by technology

Existing plastic pipes are generally simple plastic pipes with relatively low strength. Moreover, this kind of plastic pipe has a large expansion coefficient under certain conditions, and the pipe is easy to soften and deform, so it is not easy to be widely used.
