Common Defects and Prevention of Welded Pipe
Defects produced in the actual production of high-frequency welded pipes (erw steel pipe) are sometimes not caused by one reason, but are usually the result of a combination of multiple factors. Weldi...
Anti-corrosion Treatment Method for Inner and Outer Walls of Seamless Steel Pipe
Compared with traditional pipes, seamless steel pipes have lighter raw materials, high strength, good durability, can withstand higher internal pressure, are sensitive in production and use, and can b...
Causes of Cracking of Seamless Steel Pipes
Recently, our company’s small partners often encountered customer feedback in the process of talking with customers. In their previous procurement experience, they often encountered the problem of cra...
Causes of Pits on the Surface of Seamless Steel Pipes
The surface problem of seamless steel pipes is the most common one in the process of purchasing seamless steel pipes by all customers. We often encounter customers who conflict with downstream custome...
Influencing Factors of the Inner Hole Finish of Cold Drawn Seamless Steel Pipe
How much smoothness of the inner hole of the cold drawn seamless steel pipe can be achieved? This is mainly based on the customer's product requirements. In the field of hydraulic steel pipes, the inn...
Welding Distortion Correction Method
Generally, the deformation of welded parts does not need to be corrected. Only when the post-weld deformation exceeds the technical requirements, it needs to be corrected. The welding deformation is m...
Weld Treatment of High Frequency Straight Seam Steel Pipe
High-frequency straight seam steel pipe (ERW welded pipe) is based on the principle of electromagnetic induction and the skin effect, proximity effect and eddy current heating effect of electric charg...
Significance of Proximity Effect to the Production of High-frequency Welded Pipes
In addition to the skin effect, the proximity effect is another feature of current. When alternating currents of equal magnitude and opposite directions pass through two adjacent conductors, the curre...
How to Avoid the Quality Defects of Welded Pipe in Sizing Section?
Dimensional tolerance defects, surface defects and straightness defects are common defects of welded pipes in the sizing section.
1. Dimensional tolerance defects
The adjustment difficulty of the ...
The Background and Classification of Upset Tubing
Upset tubing, as the name suggests, is to thicken the tubing to make the tubing more robust and durable. The thickness of a standard pipe is not increased randomly. Increasing randomly may cause crack...
