Connection and cleaning methods of large-diameter steel pipes
Cleaning methods of large-diameter steel pipes: 1. Shot blasting and rust removal: The blades are driven to rotate at high speed by a high-power motor, so that steel sand, steel shot, wire segments, minerals, and other abrasives are sprayed on the surface of the steel pipe under the action of cen...Read more -
Surface treatment of thick-walled straight seam steel pipes
The uniformity of the pipe wall of thick-walled straight seam steel pipes will directly affect the later processing parts. If the pipe wall of thick-walled straight seam steel pipes cannot be controlled, the overall steel pipe cannot be strictly controlled. Small and medium-sized steel, wire rods...Read more -
Large-diameter straight seam steel pipe welding process and production method
Detailed explanation of large-diameter straight seam steel pipe welding process: Double-wire automatic welding of straight seam steel pipe is a welding technology developed in recent years. In addition to the characteristics of semi-automatic single-wire welding, it also has welding characteristi...Read more -
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
