Austenitic stainless steel refers to stainless steel with austenitic structure at room temperature. When the steel contains about 18% Cr, 8%~10% Ni, and about 0.1% C, it has a stable austenite structure. Austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and high Cr-Ni series steel developed on this basis by increasing the content of Cr and Ni and…
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 MoreSubmerged arc welding (SAW) is one of the most efficient mechanized welding methods today. Its full name is automatic submerged arc welding, also known as automatic arc welding under the flux layer. Submerged arc welding technology is ideal for important applications such as pipelines, pressure vessels and storage tanks, rail manufacturing and large-scale construction. Available in the simplest form…
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…
