How to make stainless steel tube? YXH Stainless steel tube mill can do it.

About the production process of stainless steel tube:

Part 1: Rolling & Annealing

It is a metal heat treatment process in which the workpiece is heated to a predetermined temperature, and then slowly cooled after holding for a certain period of time. The purpose of annealing is: 1. Improve or eliminate various structural defects and residual stress caused by steel in the process of casting, forging, rolling and welding, and prevent deformation and cracking of the workpiece.

2. Soften the workpiece for cutting

3. Refine the grains and improve the structure to improve the mechanical properties of the workpiece

4. Prepare the organization for final heat treatment and tube making

Part 2 : Slitting-slitting machine

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 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.

Part 3 : Welding and bead grinding (tube mill)

The most important process of stainless steel tube, stainless steel mainly adopts argon arc welding and plasma welding, argon arc welding shielding gas is pure argon gas, mainly welding stainless steel tube below 3mm, plasma welding has relatively strong penetrating power, mainly welding 5- 8mm stainless steel tube.

In the process of welding stainless steel pipe, it is necessary to carry out corresponding polishing and water cooling treatment on the outer weld bead. After the weld bead is first water cooled, the weld bead is polished until it is flat.

Part 4 : Shaping and cutting (tube mill)

The process of stainless steel welded tube is called extrusion production. All square and rectangular pipes are originally from round pipes. By producing round pipes with the same perimeter, they are then extruded into 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, burrs will be generated and further trimming is required. The other is metal saw cutting, which has relatively good accuracy and no burrs after cutting.

Part 5: polishing (tube polishing machine)

Tube surface polishing includes round tube polishing and square tube polishing, mirror polishing, sanding, etc. Different customers have different requirements for the brightness of the stainless steel tube surface, so the matching polishing materials will also be different.

The above is the production process of stainless steel pipe.
