Analysis of Factors Affecting Welding Quality of High Frequency Welded Pipe
The factors affecting the welding quality of high-frequency welded pipes mainly include the following aspects:
(1) Welding pressure
It is one of the main parameters of the welding process and affects ...
Advantages of Spiral Pipes
Spiral pipe has the following advantages:
(1) Steel pipes of the same width can be used to produce steel pipes of different diameters. In particular, large diameter steel pipes can be produced from bi...
Brief Introduction of Spiral Steel Pipe Technology
Brief introduction of spiral steel pipe technology is as follows:
The first: Appearance quality
1. There should be no cracks, knots, folds, and other defects on the surface that exceed the nominal wa...
Spiral Steel Pipe Deformations When Sinking Drawing
After the sinking drawing, the outer surface area of the spiral steel pipe manufacturer is increased, and the surface area of the inner surface is reduced, so a neutral layer appears between the inner...
Processing Technology of Longitudinally Submerged Arc Welding Pipe
The main processing methods for longitudinally submerged arc welding pipe are:
Forged steel: A pressure processing method that uses the reciprocating impact of a forging hammer or the pressure of a pr...
Selection of Straight Seam Submerged Arc Welded Steel Pipe
(1) For pipelines with high peaking requirements, the user's gas consumption is very uneven, the pipeline pressure fluctuates frequently, and the alternating stress of the steel pipe is large. The exi...
Several Welding Processes for LSAW Steel Pipe
The joint formed by the lsaw steel pipe when joining the two connected bodies is called a weld bead. Both sides of the weld are subjected to welding heat during welding, and changes in structure and p...
Extrusion Control in LSAW Steel Pipe Production
In the process of manufacturing lsaw steel pipe, lsaw steel pipe manufacturers need to have very good control of the pressing force. This is because during the welding process, when the temperature of...
How to Prevent the Deformation of Spiral Steel Pipe End
We know that the ports of spiral steel pipes should be round, affecting the installation and use of spiral steel pipes, but due to external factors and other factors, the spiral steel pipes become an ...
Principle Requirements for Spiral Steel Pipe Stacking
1. The principle requirement of spiral steel pipe stacking is to ensure that the code is stable and safe, and that the materials of different varieties should be palletized separately to prevent entan...
