"ERW steel pipe" refers to a high-frequency straight seam resistance welded pipe, abbreviated as ERW, that is used to transport oil, natural gas, and other vapor-liquid objects and can meet various high and low-pressure requirements. The field is critical.

1. Welded pipe refers to standard "submerged arc welded steel pipe," denoted by the letter "SC" in electrical engineering. It is relatively thick and can be used as a water gas pipe or a threading pipe.

2. The line pipe is also the wire pipe, which is represented by the letter "T" and can only be used as a threading pipe.

3. ERW pipe is an abbreviation for "high-frequency resistance welded steel pipe." It differs from the welding process used for standard welded pipes. The weld seam is formed by melting the steel strip body's base material, and its mechanical strength is greater than that of ordinary welded pipes.

"LSAW steel pipe" is the main technical characteristics of straight seam submerged arc welded steel pipe:

1 The deformation of the steel plate during the forming process of the steel pipe is uniform, the residual stress is low, and the surface does not produce scratches. Processed steel pipes have greater flexibility in the diameter and wall thickness ranges of steel pipes, particularly in the production of high-grade thick-walled steel pipes, particularly large-diameter thick-walled pipes. In terms of steel pipe specifications, users have more demands.

2. After pre-welding, the process of internal and external welding (finish welding) can realize welding at the best position, and it is not easy to have defects such as wrong edge, welding deviation, and incomplete penetration, and it is easy to control the welding quality.

3 Overall mechanical diameter expansion can effectively improve the dimensional accuracy of steel pipes and improve the distribution of internal stress in steel pipes, thereby avoiding damage caused by stress corrosion, and it is also advantageous to on-site welding construction.

4 Carry out 9 100% quality inspection items on steel pipes, so that the entire steel pipe production process is effectively inspected and monitored, effectively ensuring product quality;

5 The entire production line's equipment is networked with the computer data acquisition system to achieve real-time data transmission and the production is controlled by the central control room.

"High-frequency straight seam welded pipe" straight seam steel pipe is a steel pipe with a weld seam that runs parallel to the steel pipe's longitudinal direction. Metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe, and so on are the most common types. Straight seam welded pipe manufacturing is simple, with high production efficiency, low costs, and rapid development.
