Influence of water pressure on welded pipe

Influence of water pressure on welded pipe

1. Water pressure is one of the key factors affecting the quality of welded pipe

In the production process of welded pipes, water pressure is an indispensable link. By conducting hydraulic pressure tests on steel pipes, the strength and hardness of welded pipes can be tested, and welding defects and quality problems of the pipe shell can also be discovered. Therefore, when making welded pipes, the requirements for water pressure must be strictly implemented, and it is also one of the key factors affecting the quality of welded pipes.

2. Excessive water pressure will have a negative impact on welded pipe

Although water pressure is an essential part of making welded pipe, excessive water pressure can also have a negative impact on welded pipes. If the water pressure is too high, it will cause problems such as dents and bulges on the surface of the welded pipe, and in severe cases, it will cause the welded pipe to break. Therefore, during the production process of welded pipe, the water pressure must be reasonably controlled to ensure the quality of welded pipe.

3. How to control water pressure and ensure the quality of welded pipe

In order to ensure the quality of welded pipe, when manufacturing welded pipe, realistic hydraulic test pressures should be set based on the requirements and material characteristics of the welded pipe. In addition, the test time and pressurization speed should be controlled during the hydrostatic test to avoid unnecessary damage to the welded pipe due to improper operation. In addition, attention should also be paid to maintaining the cleanliness of the water to avoid other pollutants from adversely affecting the welded pipe.

4. Summary

Water pressure is a very important link in welded pipe manufacturing and has a direct impact on the quality of welded pipe. Therefore, during the production process of welded pipe, we must attach great importance to the control of water pressure, set the hydraulic test pressure reasonably, and pay attention to controlling the operating time and pressurization speed to ensure the quality of welded pipe.
