What Are The Anti-corrosion Work Processes For Stainless Steel Pipe Flanges
Do flanges need corrosion protection? Especially stainless steel? In fact, Sanitary Elbow also needs corrosion protection. If we don't know how to protect and maintain it, it will accelerate the rust of stainless steel pipe flanges. So what should we do to play an anti-corrosion role? What are the standard processes for stainless steel pipe flanges?
Everything needs corrosion protection, including elbow flanges. Even products produced according to standards are no exception. For example, large-diameter stainless steel flanges need to use corrosion protection measures. They need to be oiled or galvanized to be corrosion-resistant. All flanges are no exception.
In fact, corrosion protection measures will be taken in production. In the actual construction process, there are countless cases or experiences. In the production, steel pipe anti-corrosion radiation cross-linked polyethylene heat shrink tape will be added. This kind of corrosion-resistant material can produce good flanges, but large flanges are mainly carbon steel. Large flanges are applicable to oil and gas transportation projects and chemical industries. Such large enterprises cannot be sloppy.
The production process of anti-corrosion flanges is mainly reflected in the four methods of forging, casting, cutting and rolling, which are also necessary steps. However, large flanges are also divided into several types. The standards include threaded steel pipe flanges with necks, GB/T 9115-2010 butt-welded steel pipe flanges, GB/T 9116-2010 flat-welded steel pipe flanges with necks, GB/T 9117-2010 socket-welded steel pipe flanges with necks, and GB/T 9118-2010 butt-welded ring-necked loose-sleeve steel pipe flanges.
Generally, large stainless steel flange covers are buried in the lower part and are easily corroded. When installing, they are wrapped with heat shrink sleeves. Its anti-corrosion standard is also carried out in accordance with the national standard.
