在给水管暗敷中试压问题，若不试压漏水将会很麻烦，PVC管业加盟，好浇注地坪时给管道保压。漏水属于质量问题，按照规范要求进行打压，严把熔接质量关。
The problem of pressure test in the concealed laying of water supply pipe will be very troublesome if there is no pressure test， so it is good to keep the pipe pressure when pouring the floor. Water leakage is a quality problem， according to the specification requirements for pressure，PVC管业生产， strictly control the welding quality.
PPR管施工后须经试压验收后方能封管和使用。PPR管安装主要采用热熔管件，熔接时间和压力不好掌握，工艺随机性较大，在热熔推接过程中易产生堆料从而减小通径，并使熔接处成为不规则的缺陷区，产生应力集中，泉州PVC管业，影响PPR管价格的长期性能；对于PPR管的电熔连接，由于电熔丝主要采用促进PPR降解的铜，会加速PPR管的老化。
PPR pipe can be sealed and used only after pressure test and acceptance.The PPR pipe is mainly installed with hot-melt pipe fittings. The welding time and pressure are not well mastered， and the process is random. In the process of hot melt push welding，PVC管业电话， it is easy to generate stacking materials to reduce the diameter， and make the fusion joint become an irregular defect area， which produces stress concentration， which affects the long-term energy of price of PPR pipe; For the electric melting connection of PPR pipe， the aging of PPR pipe will be accelerated because copper is mainly used to promote the degradation of PPR.
