Spiral welded pipe production process
Spiral welded pipe is also a type of welded pipe equipment. Its strength is generally higher than that of straight seam welded pipe. It can use narrower billets to produce welded pipes with larger diameters. It can also use billets of the same width to produce welded pipes with different diameter...Read more -
What should be done at the end of cooling large diameter steel pipes
(1) When the cooling of the large diameter steel pipe ends, that is, when the temperatures of the surface layer and the core are all consistent, the elastic deformation of the surface layer and the core will all disappear and return to the original state. Although instantaneous thermal stress is ...Read more -
Technical requirements for steel bending pipe and analysis of factors affecting elbow quality
Steel bending pipes are produced step by step and then made into finished products. During the entire production process, there are requirements that the pipes must be bent. In addition, the bending of the pipes requires certain techniques, and the degree of bending is also different. So What are...Read more -
Technical characteristics of double-sided submerged arc welded spiral steel pipe
1. During the forming process of the steel pipe, the deformation of the steel plate is uniform, the residual stress is small, and there is no scratch on the surface. The processed steel pipe has greater flexibility in the diameter and wall thickness of the steel pipe size range, especially in the...Read more -
Significance of oil casing heat treatment process
In addition to being used for oil extraction, the emergence of oil casing can also be used as a pipeline for transporting raw materials. To enhance the quality of the oil casing, every link in the production process is particularly important, especially the temperature control during the period m...Read more
