There are many kinds of alloy steel pipes. How do we detect and judge? I will tell you the following points:
1, the production of alloy steel pipe, most are derived from hot-rolled, rarely cold drawn alloy pipe;
2. The face of the alloy steel pipe should have the original header, and the appearance of the header is very vague;
3, the length of alloy steel pipe is generally between 8-12, if you find that the length of the alloy steel pipe is less than 5 meters, we can determine that the cold-drawn alloy steel pipe, cold-drawn alloy steel pipe is the bad point, can not be slightly bent, if There will be small cracks in the microbends.
4, we can use the spectral test, this method is also the most cost-effective way, the basic material of spectral analysis can be tested, but it is difficult to test the mechanical properties of alloy steel pipe.
5, alloy steel tube with G and without G, I give a list of sub: 12cr1movg alloy tube and 12cr1mov alloy tube, their difference:
12cr1movg alloy pipe is a high-pressure alloy pipe, generally used in high-pressure boilers, power pipes and other places where pressure, his pressure will generally be 300-450 kg.
12cr1mov alloy pipe is an ordinary alloy pipe, generally used for special machining, there is no pressure of the pipeline, his pressure is generally within 100-150 kg.
