Calendering and annealing
A metal heat treatment process in which the workpiece is heated to a predetermined temperature, held for a certain period of time, and then slowly cooled. The purpose of annealing is:
• Improve or eliminate steel in the casting, forging, rolling and welding process caused by various structural defects and residual stress, prevent the workpiece deformation, cracking.
• Soften the workpiece for cutting.
• Refine the grain, improve the structure to improve the mechanical properties of the workpiece. (4) prepare the organization for the final heat treatment and piping
The most important process of stainless steel tube is argon arc welding and plasma welding. The shielded gas of argon arc welding is pure argon. The stainless steel tube under 3mm is mainly welded.
Weld bead grinding
In the process of stainless steel pipe welding, it is necessary to polish and water cool the weld bead on the surface accordingly. After the weld bead is first cooled by water, directly polish the weld bead to flatness with a water mill. Generally, 3-5 groups of water mill are added according to the thickness of the stainless steel pipe to polish and repair the weld bead.
The process of stainless steel welded tubes is called extrusion production. All square and rectangular tubes are originally from circular tubes, which are produced with the same circumference and then extruded into corresponding square and rectangular tubes. Finally, they are shaped and straightened with molds.
Stainless steel pipe cutting process is relatively rough, most are cut with grinding wheel, cut will produce cape, need to be further trimmed; In addition, one kind is band saw cutting, with relatively good accuracy. There is also cloak heat treatment. For tubes for special purposes, bright heat treatment is needed to make the ductility of the tubes reach a higher level.
There are several processes for the surface treatment of common product tubes and decorative tubes, polishing, divided into 400#, 600#, 800#, and drawing sand is divided into round sand and straight sand, there are 180#, 240#, 400#, 600#, 800#, respectively applicable to different levels of customer needs.

Flange, also known as Flange or Flange. A flange is a part that connects the pipe to the pipe and is connected to the end of the pipe. There are holes in the flange and bolts make the two flanges tightly connected. Gasket between flanges. Flanges are threaded connection flanges and welded flanges.
