Cold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
Read MoreWelding problems are sometimes encountered during the installation of carbon steel tubes. So, how to weld tubes? What should we pay attention to when welding carbon steel tubes? 1. Gas welding Gas welding can be used for welding, which is to mix combustible gas and combustion-supporting gas together, use it as the heat source of the flame, and then…
Read MoreLow carbon steel is a type of carbon steel. Carbon is present in all steels, and as long as carbon is the predominant alloying element in this steel, the alloy is considered carbon steel. “Low carbon” steel is another name for low carbon steel, and there are other carbon steels with different carbon contents. Which one is better depends…
Read MoreThe billet used in the production of steel pipes is called tube billet. Usually high-quality (or alloy) solid round steel is used as the tube billet. According to different production methods, carbon steel seamless tubes have billets made of steel ingots, continuous casting billets, forging billets, rolled billets and centrifugally cast hollow billets.Since the quality of the tube billet…

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 MoreAlloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr,…
