Effect of steel pipes drawbacks for whole quality

by Na Huang SEO

We all know that there are high demands for seamless steel pipe when they are applied for the oil and gas transportation. However, we should figure out the basic drawbacks for the whole quality of the steel pipes so that we can choose the right one for our daily life usage.

 

Sickle bend, wave-shaped, longitudinal nibbling would be some common drawbacks for steel pipes due to the incorrect production methods. Sickle bend and wavy usually appear in the cold-rolled strip rolling process, which is formed by the control of the amount of rolling down properly. In the pipe forming process, the sickle bend and wavy strip will lead to the deviation or overturning, thus the simple weld weld occurs, and it finally affect the impact of pipe quality. The bite of the strip (for example, the jagged edge of the strip) is usually present on the slitting strip because of the blunt or unscrupulous slitting of the slitting disk blade. Because of the bite of the strip, there is a lack of local meat with time going on, so that when the strip is easy to crack in the welding, cracks affect the stability of the weld quality.

 

As manufacturer, we should avoid these situations and provide high quality products for customers.
