china longitudinal welded steel pipe longitudinal welded

  • china longitudinal welded steel pipe longitudinal welded

  • If the chromium content in china longitudinal welded steel pipe longitudinal welded alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

But for pipes of the same length, the helical welding seam is 30 to 100% longer than the longitudinal welding seam, thus, the welding cost is higher and the welding efficiency is lower.See all results for this question

What is the difference between longitudinal and helical welding?

But for pipes of the same length, the helical welding seam is 30 to 100% longer than the longitudinal welding seam, thus, the welding cost is higher and the welding efficiency is lower. Therefore, longitudinal welding is more used to produce small diameter pipes, while helical welding is always used for pipes of large diameters.See all results for this questionWhat is longitudinal welded pipe?Comparatively speaking, longitudinal welded pipe has simple manufacturing and welding techniques. As the name shows, longitudinal pipe has a straight welding seam on the pipe surface.See all results for this questionWhat Are Differences Between Spiral Welded Pipe and china longitudinal welded steel pipe longitudinal weldedThe test of spiral welded pipes and longitudinally welded pipes has been done that it indicates that the spiral welded pipe has a high impact toughness. When it comes the applications, the spiral welded pipes are popular. Processing process of spiral welded steel pipe is strict as well as the test requirement.

Thus, inevitably, many T-shaped welding seams would appear in this welding process, largely increasing the possibility of welding defects.Difference Between Helical Welded Pipes And Longitudinal china longitudinal welded steel pipe longitudinal weldedAs for longitudinal welded pipes, to meet the required length of pipelines used in industry projects, short longitudinal pipes always need to be jointed and welded into a long enough pipe. Thus, inevitably, many T-shaped welding seams would appear in this welding process, largely increasing the possibility of welding defects.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This china longitudinal welded steel pipe longitudinal welded alloy steel china longitudinal welded steel pipe longitudinal welded still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
