The so-called cold processing production, that is, the cold pull-up process, cold rolling process or cold-rolled-cold pull-out process production and production of stainless steel tubes. At present, my country's stainless steel pipe application field is mainly based on "cold rolling and cold pull -out hot rolling" products, while stainless steel pipes are also widely used in petroleum, chemical industry, boilers, power stations, ships, machinery manufacturing, automobiles, aerospace, energy sources, energy sources , Geology, architecture and military industry and other industries.

Some inferior stainless steel tubes on the market usually have shortcomings such as insufficient size, tube parts are easy to burst, and the surface technology is not precise. So how does the stainless steel pipe produced in cold processing ensure quality and ensure that the product technology is more precise?

The manufacturing process is to use a large -caliber waste tube. It runs between various processes through the combination of cold rolling and cold pull -out, that is, to achieve surface smoothness and wall thickness, and qualifying for mechanical properties, and shorten the process.

In the production of stainless steel pipes, semi -finished pipes will also be exploring through vortex, using machines to detect defects and flaws and eliminate grinding, and then cold rolled to the finished product specifications, so as to ensure the quality indicators of the finished pipes. Avoid the hidden defects inside the stainless steel tube, causing the cracking and even break of the stainless steel tube.

During the production process, the natural gas -controlled solid -soluble furnace controlled by a computer is also used to make the furnace temperature uniform, controlled by the atmosphere, and cooling, and monitor the error values of each section of the pipe parts in real time to adjust the mechanical equipment parameters. Strict and perfect production details determine the final quality level of the pipes.

In order to ensure the unity of the quality of the finished stainless steel pipe, the following measures will also be taken to improve the quality of processing:

1. Fully eliminate the remnants of the lines and concave pits in the waste tube, reduce the twist of the lattice in the finished product, improve the plasticity and toughness of the stainless steel tube, increase the limit of the yield and the impact toughness, and reduce the wall thickness difference in the proximity of the finished product;

2. Machining the finished process mold through the control grinding machine to ensure the smoothness of the finished tube;

3. Use computer -controlled sealing circulatory acid washing grooves to filter out the iron oxide in the acid liquid at any time to avoid iron oxide on the surface of the tube and form a defect in the lower road processing;

4. Using the RFID-MES intelligent management system, the production of products produced from sales contracts, raw materials inspection, product manufacturing, inspection and testing, logistics distribution, product sales and service establishment Essence
