How to distinguish the quality of Chinese grade 45 seamless pipe

High quality Chinese grade 45 seamless pipe has strong rigidity and hardness, so it is not easy to fold when using. Even bending is very difficult. However, it is not the case for fake and shoddy products. It may look like thick walled steel pipe on the outside, but the thickness of steel pipe deep may not reach certain standard, and it is easy to fold or bend in weak position. The poor quality grade 45 seamless pipe can be identified by this method.

In addition to these, most of the Chinese grade 45 seamless pipe manufacturers have high production technology, and the production process is relatively advanced, the product surface is very smooth, but some small workshops produced products do not have such characteristics, the surface looks uneven, and even has very obvious defects. That because their rolling workers art is not skilled enough, so this is also a way to identify the quality of Chinese grade 45 seamless pipe.

At the same time, we can also judge the quality of Chinese grade 45 seamless pipe by checking whether there are cracks on the surface of Chinese grade 45 seamless pipe. For Chinese grade 45 seamless pipe, because its strength is relatively large, it is not easy to scratch. These methods can effectively identify the quality of Chinese grade 45 seamless pipe, so we must learn to avoid being deceived and buy fake and inferior steel pipes.
