Installation of trench pipe will encounter a lot of failures, such as tap water leakage, clamp axial tear, after compression is not right angle and so on. Although the groove pipe fittings can solve many of the traditional welding connections exist, but in the installation process must pay attention to remove some of the failure, otherwise it will affect the performance of the use.
Groove pipe leakage problem is more common, the main reason is the improper operation of the installation. Specific may be due to the installation of lubricants, friction caused by excessive accumulation of rubber ring, resulting in pipe joints to reduce the pressure, resulting in water leakage. But the pressure can not be too much, more than a certain limit will lead to more serious leakage or clamp axial fracture. This is generally caused by the uneven bolt tightening caused by the force to break the bar.
The above is a common fault analysis of the installation of grooved pipe fittings, if the installation does not pay attention to the details of the performance will result in the weakening, and even the impact of the entire system.
