During my study abroad, I visited some manufacturers. The largest stainless steel production line I have ever seen belongs to a set of automatic production lines imported from Germany. The basic link of the production line has the following points: 1. It is the hoisting area: that is, you should not have a crane and other machinery, hoisting steel belt in the first production link. Two, sent into the molding machine. Moulding machinery includes 2 sets of main equipment, 1: modeling mold, 2: is an argon arc automatic welding machine. In this way, a semi-finished stainless steel profile can be produced. Three, it is automatic cutting area: this is a equipment connected with the semi-finished product line, in your own size and length can complete the automatic cutting equipment. Four, semi-finished polishing equipment: the production of rough semi-finished products can be polished, the production of finished products. Five, is the label, packaging. The production process described above is my personal point of view. I don't know how big the large production line you need can be and what kind of products you can produce. If you can ask more accurately, I can give you a more complete equipment configuration according to the production line you need. I hope I can help you.

Seamless stainless steel pipe is widely used in high pressure, low temperature and corrosion resistance environment piping, mechanical properties, process performance and corrosion resistance are three important indicators to measure the quality of steel pipe, but also to ensure the important guarantee of safe navigation of ships. In the real ship application, a stainless steel chemical ship, after the first voyage, the deck cargo piping leakage was found, the pressure test found more than 10 holes leakage. During the manufacturing process of an ethylene Marine cargo tank, it was found that many problems were found on the inner surface of the tank penetrator, including pitting and surface cracks. So how can these problems be fundamentally solved? According to the production flow chart of stainless steel seamless tube (Figure 1), round steel billet is made into seamless steel tube through perforation, cold drawing/cold rolling, solid solution, straightening, pickling and other major processes. Each pipe making link is complementary to each other, especially for the quality control of raw materials and intermediate products. It is an important guarantee to ensure that the finished pipe's chemical composition, surface quality, mechanical properties, process performance and corrosion resistance meet the specifications and standards.
