For our current cities, cement pipes are mainly used for underground drainage systems in our cities. Because it is buried underground and used for drainage and sewage, we have no shortage of pressure test problems when using pipelines in the installation. Whether it is the pressure from the ground or the pressure on the road, the requirements in this regard are very high. So what are the requirements when we test the cement drainage pipe? Let's take a look with the editor of the cement pipe factory!

The sockets are connected by socket-type double O-rings, so each pipe of each device must be suppressed at the socket to check the sealing effect of the double O-rings. Use the pressure test pump directly through the pressure test hole on the top of the reinforced concrete drainage pipe. Stop the pump after adding water to the pressure 1.5 times the working pressure of the pipeline (open the drain valve during operation), investigate for 2 minutes, the pressure drop value does not exceed 5% of the test pressure, and there is no leakage at the nozzle. Nozzle pressure test is qualified.

So no matter what kind of products and equipment, as long as we want to put it into use, we must pass repeated tests to verify whether its products are suitable for our use. This is also a guarantee for our later use.
