904L stainless steel plate is a kind of pipe fittings, which carries out a circle of argon arc welding between the stainless steel pipe and the pipe fittings along the butt joint, usually welding. According to the edge welding part of 904L stainless steel plate, there are three types of 904L stainless steel plate: groove extension, step edge extension and no extension. The socket welding specification is generally DN15-DN100.

Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel S690QL steel not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.

The advantages of flame cutting are simple cutting and low cost. The disadvantage of flame cutting is that when cutting thin plates, cutting deformation problems are prone to occur, and the materials that can be cut have certain limitations. The advantage of CNC cutting is that it can cut S690QL steel and any complex parts with high cutting accuracy. The disadvantage of CNC cutting is that there are certain operational and technical requirements.
