The quality inspection method of spiral pipe (ssaw) is as follows: 1. Judging from the surface, that is, in visual inspection. Visual inspection of welded joints is a simple procedure with various inspection methods and is an important part of finished product inspection, mainly to find welding surface defects and dimensional deviations. Generally, it is observed by naked eyes…
Read MoreSpiral welded pipe (ssaw) is a kind of steel pipe that combines low-carbon and environmentally friendly alloy structural steel and low-alloy structural characteristics into pipe material and electric welding. How can the reliability of the spiral pipe be improved in the process of adoption? When we store it, we need to ensure the upper block and the lower pad,…

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 MoreSpiral 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 MoreLow temperature carbon steel pipe is a medium carbon structural steel. It has good performance in cold and hot heating, good mechanical properties, low price and wide source, so it is widely used. Its biggest weakness is low hardenability, and workpieces with large cross-sectional dimensions and relatively high requirements should not be used. Cold steel running at low temperature…
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…
