The forming methods of manufacturing large-diameter longitudinally welded pipes include UOE forming method, roll forming method (CFE), CE forming, and so on. For most of the farming methods, the latter process is to perform a full-length expansion of the welded tube blank to improve the welded steel

The difference between casing and drill pipe:

In the process of producing straight seam steel pipes, the temperature must be strictly controlled to ensure the reliability of welding. If the temperature is too small, the welding position may not reach the temperature required for welding. When most of the metal structure is still solid, it is di

Can carbon steel pipes and stainless steel pipes be directly welded? Carbon steel pipes/tubes and stainless steel pipes can be welded directly. However, it is important to note that due to the significant differences in their chemical composition and physical properties, adjustments must be made during the welding process to avoid welding defects and other issues.

Controlling the wall thickness of straight seam steel pipes is a difficult point in the production of steel pipes.1. Tube billet heatingThe heating should be average to prevent the rapid rise and fall of the temperature. The temperature of each rise and fall should be steady and slow, and the temper

Advantages of square tube:

Most merchants did not use the straight seam steel pipe soon after purchasing it. So is there anything we need to pay attention to in the storage of straight seam steel pipes? The staff of the straight seam steel pipe manufacturer reminded us that the correct storage method of the straight seam stee

To determine whether the size of seamless carbon steel pipes meets standard requirements, the following inspections are required:
