Spiral pipe (SSAW) is also called spiral steel pipe or spiral welded pipe. It is made by rolling a low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain helical angle (called a forming angle), and then welding the tube seams. It can produce large diameter pipes from narrower strips. Spiral pipes are mainly…
Read MoreDue to the increasing bearing pressure of the pipeline, the use conditions are becoming more and more severe, and the service life of the pipeline should be extended as much as possible. In order to improve competitiveness, carbon steel pipe manufacturers should research and innovate in what aspects, and what are the main development directions of spiral welded pipes?…
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 MoreHydraulic test is a method to detect the defects of SSAW steel pipe, which is widely used in the inspection of various pressure steel pipes.When the steel pipe is subjected to the hoop tensile stress during the hydrostatic pressure test, if the performance of the steel pipe does not meet the requirements or has defects, it will bend, crack,…

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…
