What is the point of a seamless elbow in order to be a national standard elbow?
1. The problem of the length of the elbow, when the length of the seamless elbow is not reached, then the elbow elbow is not reached, and the most affected is that the elbow pressure is directly affected.
2. The problem of elbow thickness, seamless elbow deviation wall thickness is within the scope of the national standard. The deviation wall thickness of 0.875 is allowed by the state. When we purchase, we must see whether the actual thickness reaches the deviation of 0.875 GB.
3.
