At present, the proportion of oil and gas transported by longitudinally welded pipes in the world is increasing, accounting for about 75%-95% of the total oil and gas. The scope of transportation is gradually expanding, not only petroleum and natural gas, but also various chemical industries.
Raw materials and products, and the use of longitudinally welded pipes(ERW Steel Pipe) to transport solids has been studied. The development direction of longitudinally welded pipe pipeline transportation points to the direction of large diameter and high pressure.
The use of longitudinally welded pipes to transport fluids has the following advantages
What are the characteristics of welded pipe compared with seamless steel pipe?
The difference between different specifications of straight seam steel pipe
There are many types of steel pipes, which can be divided into straight seam steel pipes and spiral steel pipes according to the welding method. Because the two steel pipes have different welding methods, the performance is also different.Three production processes of welded pipe
This time we mainly introduce welded steel pipe, that is, welded steel pipe. Its production is to bend the tube blank (steel plate and steel strip) into the required cross-section shape and size tube by various forming methods, and then weld the weld by different welding methods to get the steel pipe.The influence of welded pipe blank width consumption
Welded pipe blank is the raw material for manufacturing welded pipe. Its mechanical properties and chemical composition have a far-reaching impact on the quality of welded pipe. Its width is an important factor to determine the weld strength. We usually say that the appropriate width of welded pipe blank refers to the width of a given thickness. The determination of the width is restricted by many factors.
