Read MoreIn the production process of spiral steel pipe, if the production process is unreasonable and the machine parameters are not properly set, there will be deviations, especially for large-diameter spiral steel pipes, which is often referred to as the wrong side phenomenon. During the production of spiral steel pipe, the wrong side occurs from time to time, and there…
Read MoreBecause oil and gas pipelines are buried underground for a long time, they are very prone to corrosion problems due to soil, moisture and other factors. At present, pipeline corrosion in the petrochemical industry is mainly divided into two types: 1) External corrosion, the so-called external corrosion specifically refers to the corrosion caused by the connection between the metal…
Read MoreThe hot extrusion process of seamless steel pipe is a pressure forming method, which is to place the tube blank in a pressure-resistant container, and apply external force to cause the tube blank to plastically deform under the state of three-dimensional compressive stress. During extrusion, the tube blank is in a state of three-way compressive stress, so it can…
Read MorePrecautions for seamless tube production: 1. Pay attention to whether the thickness of the capillary wall is uniform. If it is found that the thickness of the capillary wall is uneven, the surface polishing treatment must be performed. In addition, whether the inside and outside of the capillary tube is flat and there are no bumps and defects. Once…
Read MoreTension reduction rolling is the last hot rolling process in the production of seamless steel pipes, which plays a decisive role in the control of product quality. The tension reduction of seamless steel pipe is a continuous rolling process without mandrel. During the rolling process, the outer diameter and wall thickness of the rolled piece are changed by the…
