Among the common problems of seamless steel pipes, wall thickness difference (eccentricity) occupies the first place. Wall thickness difference, as the name implies, is the difference between the maximum wall thickness and the minimum wall thickness. As long as it is a seamless steel pipe, there will be wall thickness deviation, but how much can this deviation be controlled? If the wall thickness deviation of seamless steel pipes is too large, what impact will it have on customers’ products?
The impact of uneven wall thickness of seamless steel pipes
In some mechanical processing application fields, the wall thickness deviation of seamless steel pipes is a very important indicator. If the wall thickness deviation is too large, a larger margin is required, which wastes materials and increases costs. It is difficult to take orders and has no market competitiveness.
How to control the wall thickness deviation of steel pipes to help customers save costs
The source of steel pipe production-perforation
- With sophisticated perforation equipment (extended type), the furnace length is equipped with preheating, heating, and high-temperature zones. Natural gas nozzles are used throughout the process, and the temperature is uniform to ensure the perforation quality.
- Using high-quality alloy plugs, the perforation quality is better and more stable.
- Keep sampling records throughout the perforation process, and inspect each tube after perforation to ensure the quality of the tube.
- For general small steel pipe factories (processing workshops), perforated tubes are generally purchased from outside, and the quality of the tubes cannot be controlled and guaranteed from the source.
