Uses and functions of large-diameter straight-seam welded steel pipes
1. The uses of large-diameter straight-seam welded steel pipes can be divided into oil well pipes (casing, oil pipes, drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic support pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure fertiliz...Read more -
Forming process of thin-walled welded steel pipe
1. Downslope forming method: Downslope shaping of welded pipe equipment can significantly reduce edge extension. 2. Increase the middle extension of the billet: During the forming process, the reduction of the opening pattern increases, making the gap between the upper and lower rollers slightly ...Read more -
Briefly introduce several common defects and effects of straight seam steel pipes
First, how does the edge gnawing of straight seam steel pipes occur? What is the impact on welded pipes? The edge gnawing of straight seam steel pipes usually occurs on longitudinally cut strips. The edge gnawing of straight seam steel pipes is the phenomenon that the edge of the steel strip is j...Read more -
Rust removal method and production process of large-diameter straight seam steel pipe
Large-diameter straight seam welded pipe is a general term. It is produced by steel strips. All pipes welded by high-frequency welding equipment are called straight seam welded pipes. (It is named because the welding part of the steel pipe is in a straight line). According to different uses, ther...Read more -
What details should thick-walled steel pipes go through before use
The selection of welding methods for thick-walled steel pipes should be based on the material and wall thickness of thick-walled steel pipes. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics. For example, the charact...Read more
