Read MoreAccording to the standard requirements, the dimensional inspection of seamless steel pipes mainly includes the wall thickness, outer diameter, length, curvature, ovality and end face shape of the steel pipe. (1) Wall thickness inspection The tool used for wall thickness inspection is mainly a micrometer. During inspection, use a micrometer to measure the wall thickness of the steel pipe…
Read MoreA seamless steel pipe for fluid (fluid pipe) is a steel pipe with a hollow section and no welds from the beginning to the end. It is mainly used for conveying fluid pipelines in engineering and large-scale equipment. Fluid seamless pipe production process: Round tube billet→heating→piercing→three-roll skew rolling, continuous rolling or extrusion→tube removal→sizing (or reducing)→cooling→billet tube→straightening→hydraulic test (or flaw…
Read MoreStructural seamless pipe (GB/T8162-2008) is a kind of seamless steel pipe used for general structure and mechanical structure. The fluid seamless steel pipe standard applies to seamless steel pipes that transport fluids. In addition to carbon (C) elements and a certain amount of silicon (Si) (generally no more than 0.40%) and manganese (Mn) (generally no more than 0.80%, higher…
Read More1. Use of seamless steel pipes for structures: seamless steel pipes for such structures are now more suitable for general structures and their mechanical equipment structures. Compared with others, the quality of such seamless steel pipes is There are some practical differences. 2. Use of seamless steel pipe for fluid transportation: This type of seamless steel pipe is widely…
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…
