With the continuous development and progress of society. More and more stainless steel pipe products are known and utilized by everyone. So how is the stainless steel tube produced step by step?
Customers also have certain doubts about the production process of stainless steel pipes. They believe that ordinary smelting of stainless steel pipe raw materials can produce stainless steel pipes. In fact, it is not the case. There are slight differences in the process used in the processing and production of stainless steel pipes according to different types of stainless steel pipes. Next, the stainless steel pipe manufacturer Huiyingsteel will briefly introduce the production process of stainless steel pipes.
1. Rolling annealing of stainless steel pipe workpieces
It is a metal heat treatment process that heats the stainless steel pipe workpiece to a predetermined temperature and slowly cools it after a certain period of time. The purpose of annealing stainless steel pipe workpiece is to:
1) Improve or eliminate various structural defects and residual stress caused by steel in the process of casting, forging, rolling, and welding, and prevent the deformation and cracking of stainless steel pipe workpieces.
2) Soften the stainless steel pipe workpiece for cutting.
3) Refine the grains and improve the structure to improve the mechanical properties of the stainless steel pipe workpiece.
4) Prepare the organization for final heat treatment and tube making.
2. Slitting of stainless steel pipes
The slitting of stainless steel coils is to cut the stainless steel coils into corresponding widths for further deep processing and pipe making. During the slitting process, attention should be paid to the scratches of the slitting knife on the coils, the width, and the errors of the slits. In addition, the slitting is related to the pipe-making process, and the cloak and burr of the slitting are very important for the pipe-making process.
3. Welding and grinding of stainless steel pipes
Welding is the most important process for stainless steel pipes. Stainless steel mainly adopts argon arc welding and plasma welding. The shielding gas for argon arc welding is pure argon gas. It mainly welds stainless steel pipes below 3mm. Plasma welding has strong penetrating power and is mainly used for welding. 5-8mm stainless steel tube.
In the process of welding stainless steel pipe, the surface weld bead needs to be polished and water-cooled accordingly. After water-cooling the weld bead, the weld bead is directly ground with a water mill until it is flat, and the weld bead is ground and trimmed.
Four, stainless steel tube shaping and cutting
The process of stainless steel welded pipe is called extrusion production. All square and rectangular pipes are originally round pipes. By producing round pipes with the same perimeter, they are then extruded into the corresponding square and rectangular pipes. Mold shaping and straightening.
The process of making and cutting stainless steel pipes is relatively rough. Most of them are cut with grinding wheels. After cutting, a cape will be produced, which needs to be further trimmed. The other is the band saw cutting, which has relatively good accuracy. The tube needs to be brightly heat treated to make the ductility of the tube reach a higher level.
Five, stainless steel pipe polishing
The usual product pipes and decorative pipes have several processes for surface treatment. Polishing is divided into 400#, 600#, and 800#, while stainless steel pipe sanding is divided into round sand and straight sand, including 180#, 240#, 400#, 600#, and 800# are suitable for the needs of customers at different levels.
Well, the above is the whole content of the production process of stainless steel pipes brought to you by Huiyingsteel today. I believe that everyone has an understanding of the production process of stainless steel pipes after reading the whole text. I hope the above content will be helpful to you.
