Do flanges need corrosion protection? Especially stainless steel? In fact, stainless steel flanges also need corrosion protection. No one is perfect. No matter what product is, it cannot withstand the rubbing of time. If we don't know how to protect and maintain it, it will accelerate the rust of stainless steel flanges. So what should we do to play the role of corrosion protection? What are the standard processes? Let's see the following analysis for you.

Everything needs corrosion protection, including machinery. 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. 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 corrosion protection 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. The scope of application of large flanges is oil and gas transportation engineering and chemical industry.

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 bottom and are easily corroded. When installing, they are wrapped with heat shrink sleeves. Its anti-corrosion standard is also in accordance with the national standard.
