Stainless steel pipes can not use carbon steel flanges, for carbon steel flange material can not be anti-corrosion, generally are used stainless steel pipe is due to corrosion, the pipe is usually have some stronger corrosion medium flow, can produce corrosion of pipeline, at this time if the carbon steel flange, bad flange, is bound to be corrosion caused leakage accident, So generally speaking, stainless steel pipe can not be used with carbon steel flange.

When can we use carbon steel flanges for stainless steel pipes
However, there are special cases that can be used, such as the following two cases
1. clearly know the pipeline non-corrosive medium, it can use carbon steel flange.
2. In case of emergency, if stainless steel flanges are not used, carbon steel flanges can be temporarily replaced. However, in this case, the non-standard carbon steel flanges can not be used for a long time.

What is the difference between stainless steel flange and carbon steel flange?
Carbon steel flanges and stainless steel flanges have a higher carbon content than other flanges, which gives carbon steel flanges a lower melting point and better ductility. At the same time, carbon steel flange material cost is low, simple production, so the finished product price is relatively cheap, suitable for a large variety of places, mostly used in the pipeline corrosion requirements are not high.
Stainless steel flange made of stainless steel, inherited the corrosion resistance, pollution resistance characteristics of stainless steel, and smooth appearance, good gloss, low maintenance cost, and can withstand greater pressure, can be used in corrosive requirements of the pipeline.
