Surface heat treatment is divided into two categories: one is surface quenching and tempering heat treatment, and the other is chemical heat treatment. Common hardness testing methods are as follows: 1. Surface quenching and tempering heat treatment The surface quenching and tempering heat treatment of seamless steel pipes is usually carried out by induction heating or flame heating. The…
Read MoreCold 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 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,…

Read MoreThe difference between carbon steel seamless tube and stainless steel seamless tube mainly refers to the difference in design rules between carbon steel and stainless steel, which means that the design rules of these two types of steel cannot be used in common. These differences are summarized as follows: Carbon steel 1. Ordinary steel is carbon steel, that is,…
