Wuxi stainless steel pipe factory 310S Stainless steel seamless pipe Processing technology

? one Wuxi stainless steel 310S stainless steel produced by pipe factory Seamless pipe The preliminary preparation work of

? ? Every time a batch of stainless steel billets (round bars) are purchased to the factory, they must be checked strictly in quantity and inspection. In addition to checking the technical parameters in the quality guarantee according to the national standards, we also have to take samples and test the materials to check whether the chemical elements of the materials meet the values in the quality guarantee, At the same time, advanced testing equipment such as metallographic microscope with camera function, continuous zoom stereo microscope and other advanced testing equipment were used to check whether the toughness of the material meets the requirements of national standards. Only when the data is complete and correct and the corresponding test and test reports are written, can the acceptance and warehousing work be completed.

? ? When a customer orders 310S stainless steel seamless pipe, according to the customer's requirements, the planning department of the enterprise shall establish the project, the technical department shall draw up the product drawing and process drawing, and formulate the process card, and then the production management department shall organize the production. After receiving the instructions, the processing department takes the stainless steel billet from the warehouse to the vehicle according to the procedure, and then enters the early batching and initial processing stage.

? ? The general operation procedure of the enterprise's preliminary work is as follows: firstly, according to the requirements put forward in the process card of the technical department, the round bar is cut into a specified length, and then peeled on the lathe. After that, the hole is drilled on a horizontal drilling machine with a taper at one end, forming a V shape, and the rest is a small straight cylindrical hole.

? ? After machining, the stainless steel ingot must be tested. According to the test results, the stainless steel ingot shall be grinded to remove burr, draw marks and small pits until the specified size and surface requirements are met. Then, according to the product specification requirements, the stainless steel ingots will be sent to the corresponding processing site according to the price. The following are steel rolling branch plants, waiting for the processing of subsequent parts.

? ? 2. Process key: 310S stainless steel seamless tube forming

? 310S stainless steel seamless pipe has been widely used in industry for its strong pressure bearing capacity, high temperature resistance, corrosion resistance and long service life. Especially in recent years, with the increase of long distance and cross sea transportation of liquefied gas, natural gas and liquid, the progress of communication technology (submarine cable laying), the rapid development of chemical industry, air conditioning and refrigeration machinery and environmental protection equipment, and the development of 310S stainless steel seamless pipe with square shape and round inner hole in nuclear industry, The 310S stainless steel seamless pipe has become the favorite of the times, the market is rising day by day, and the industry is booming. In the field of foreign trade, despite the strong cold current of anti-dumping in recent years, many foreign trade industries have shown weakness, while 310S stainless steel seamless pipe still maintains a good export momentum. In particular, it is sold to Saudi Arabia and other Middle East oil producing countries. The annual sales volume accounts for a large share of the total demand there. Over the years, the products are reliable in quality, timely in supply, in place in service, and cheap in quality. Therefore, it has won a good reputation in the Middle East. In the days to come, if all kinds of manufacturers can develop and innovate, constantly introduce some new products, constantly optimize the manufacturing process and reduce the production of wood, then the market space will be greater. It is completely believed that with the progress of science and technology and the development of industry, the prospect of 310S stainless steel seamless pipe will be more and more beautiful.
