How are Stainless Steel Spiral Duct made?
You can make stainless steel spiral ducts by going through the following steps:
First you need to prepare the materials that you need to make the stainless steel spiral duct.
In this case, you will prepare stainless steel 304 or 316 depending on the grade you need.
Cold galvanized Angle steel
Cold galvanizing process is used to protect the metal from corrosion. For this purpose, the coating of zinc filler is used, which is coated on the protected surface by any coating method.
Common Defects of Spiral Welded Pipes
The main cause of the bubbles in the center of the weld bead is hydrogen is concealed within the weld metal as bubbles. Thus, to eliminate this defect, remove the wire and weld the rust, oil, water, moisture, and other things, and then fully dry the flux to remove moisture. Furthermore, a higher current slows the solidification rate of liquid metal, limiting welding speed.
Does Stainless Steel Rust?
Stainless steel is armed with built-in corrosion resistance but it can and will rust in certain conditions—although not as quickly or severely as conventional steels. Stainless steels corrode when exposed to damaging chemicals, saline, grease, moisture, or heat for prolonged periods of time.
