Main application fields of stainless steel wedge wire welded pipe
Stainless steel wedge wire welded pipes are mainly used in heat exchanger pipes, fluid pipes, pressure pipes, mechanical structure pipes, urban landscape, and other industries, with annual consumption of about 700,000 tons. The demand for industrial stainless steel welded pipes is relatively high, and the production process is mature. At present, the annual volume of industrial stainless steel welded pipes in China is about 150,000 tons, some of which still need to be imported.
From the point of view of domestic stainless steel pipe products, austenitic steel is the main type of steel; products include: seamless steel pipe including cold-drawn pipe, cold-rolled pipe, hot extrusion pipe, centrifugal casting pipe, spinning pipe; welding pipe including: plasma welding, argon arc welding, submerged arc welding, light speed welding and high frequency welding pipe, etc., can produce stainless steel pipe base. It covers all kinds of standard specifications in the world. The specifications and varieties of stainless steel special-shaped tubes are more than 100 kinds. The products are used in many fields of industry and civil use. But generally speaking, the domestic stainless steel pipe has a certain gap with the market demand in terms of variety, specification, quantity and so on.
