Measures to Improve Steel Pipe Wall Thickness Accuracy

Controlling the wall thickness of steel pipes is a difficult point in steel pipe production. Measures to improve wall thickness accuracy during production mainly include the following aspects:

1. Optimize the tube blank heating process

Heating is one of the most important links in steel pipe production. Uneven heating or improper temperature control will affect the wall thickness accuracy of the tube blank. By optimizing the heating process to ensure uniform heating of the tube blank, wall thickness deviation can be reduced.

2. Select appropriate rolling tools

The wear and accuracy of rolling tools have a great impact on the accuracy of steel pipe wall thickness. Regular inspection and replacement of rolling tools, and selection of appropriate rolls and guide plates can effectively improve wall thickness accuracy.

3. Control the quality of mandrel

The mandrel is an important tool in steel pipe production. Problems such as mandrel bending and dimensional deviation will lead to uneven wall thickness of steel pipes. Improving the processing accuracy of the mandrel and selecting appropriate mandrel materials can effectively improve the wall thickness accuracy of steel pipes.

4. Adjust rolling process parameters

By adjusting various process parameters during the rolling process, such as rolling speed, pressure, temperature, etc., the wall thickness accuracy of the steel pipe can be optimized.

5. Use advanced testing equipment

Using advanced online thickness gauges and wall thickness detection equipment to monitor steel pipe wall thickness in real time and adjusting process parameters in a timely manner can effectively ensure the accuracy of steel pipe wall thickness.
