Title:
SYNTHETIC RESIN MULTI-PIPE HAVING UNEVEN INTERFACES
Document Type and Number:
WIPO Patent Application WO/2019/132225
Kind Code:
A1
Abstract:
The present invention provides a multilayer, synthetic resin pipe for a water supply pipe, wherein the pipe comprises an outer layer, an intermediate layer, and an inner layer, with each interface therebetween having an irregular cross section, whereby the synthetic resin pipe has enhanced physical properties in terms of impact strength by diffusely reflecting a shock wave generated at the inside/outside thereof and tensile force thanks to the irregular cross sections so that the pipe is prevented from being twisted or broken by external impacts or vibrations, ground subsidence, etc. Further, employing a CPVC resin, the synthetic resin pipe is also improved in heat resistance and thus can be used as a heat-resistant pipe.
