Brief analysis of the processing methods of industrial steel pipes
First, the processing and loading of steel pipes: 1. During the heat treatment process, workpieces that are easy to deform should be heated on a special fixture 2. The workpiece should be placed in the effective heating zone Second, preheating: 1. For workpieces with complex shapes or sharp chang...Read more -
What is the difference between the industrial project straight seam steel pipe and seamless steel pipe
First, different classifications 1. Straight seam steel pipe: divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe 2. Seamless steel pipe: seamless pipe is divided into hot-rolled pipe, cold-rolled pipe, cold-drawn pipe, extruded pipe, top...Read more -
Common defects in the welding area of spiral seam submerged arc welding steel pipe
Defects that are prone to occur in the submerged arc welding area include pores, thermal cracks, and undercuts. 1. Bubbles. Bubbles often occur in the center of the weld. The main reason is that hydrogen is still hidden in the welded metal in the form of bubbles. Therefore, the measures to elimin...Read more -
What is the stress state of the industrial spiral steel pipe during extrusion
(1) During the extrusion process, the temperature of the inner lining of the spiral steel pipe continues to rise as the extrusion process progresses. At the end of the extrusion, the temperature of the inner wall of the lining near the extrusion die is high, reaching 631°C. The temperature of the...Read more -
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
