(Summary description)In the actual trade environment, the quality of Jiangsu seamless steel pipes is uneven, and there are many fake and shoddy products, so how to identify the thick wall of seamless steel pipes? The following is an introduction:
The surface of fake and inferior seamless steel pipes often has pockmarks.
The flat surface refers to the irregular raised defects on the surface of Jiangsu seamless steel pipe due to severe groove wear. This is because Jiangsu seamless steel pipe production enterprises pursue profits excessively, and the groove rolling process has not been replaced.
The surface of fake and inferior seamless steel pipes is easy to form scars
There are two reasons for this situation: on the one hand, the quality of Jiangsu seamless steel pipes with poor quality is uneven, and there are many impurities; Scar on the surface of the stainless steel pipe.
The surface of fake and inferior wood is prone to cracks
The reason for the cracks is that the green body is adobe, and the adobe has large pores. The adobe is affected by thermal stress during the cooling process, and it is easy to crack, which makes the stainless steel tube crack after rolling.
