Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene sewage pipes, in particular to a polypropylene sewage pipe with an underground connection structure. Background Art

[0002] Polypropylene pipes are products used in the chemical, petroleum, chlor-alkali and other industries. Polymer-type PP materials have lower heat deformation temperature, low transparency, low gloss, and low rigidity, but have stronger impact strength. The impact strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP is 150°C. Due to the high crystallinity, this material has good surface stiffness and scratch resistance. PP does not have the problem of environmental stress cracking.

[0003] In the daily sewage discharge process of polypropylene sewage pipes, they are generally buried deep underground for sewage discharge. When installing polypropylene sewage pipes, welding technology is generally used. When the length of the polypropylene sewage pipe is too long, since the polypropylene sewage pipe is welded, its overall length may be too long. Therefore, an additional supporting structure is required to prevent the polypropylene sewage pipe from shaking during operation. The strength of the polypropylene sewage pipe after welding is not as high as its integrity. After long-term use, leakage may occur at its interface, and an additional supporting device needs to be installed after welding. The overall installation operation is more cumbersome.
