How to operate anti-corrosion work of marine flange?

The material of marine flange is stainless steel. Stainless steel is a kind of material with good corrosion resistance. This material can make the structural parts keep the integrity of design permanently. So now many building materials are made of stainless steel. Stainless steel flange is widely used in petroleum, chemical industry, nuclear power station, food manufacturing, construction, shipbuilding, papermaking, medicine and other industries. It has different uses in different industries and shows its use value in various industries.

ANSI ASME B16.5 A350 LF2 RF RTJ blind flanges

The marine flange is used in the building valve of the transmission and distribution network with cathodic protection and the buried pipe valve well with potential slice (area) isolation. The cathodic protection situation of each piece (area) of buried transmission and distribution pipe network can be clearly understood by the piece (area) isolation; the cathodic protection piece (area) is evaluated and treated according to different cathodic protection situations; when the protection potential of the adjacent piece (area) is the same (or similar) and meets the protection potential requirements, the two sides of the insulation flange can be connected by straddles for integration 1.

Protection: when the protection potential of adjacent pieces (areas) is quite different and there are pieces (areas) that can not meet the protection potential requirements, the pieces (areas) that can not meet the protection potential requirements can be specially treated until they meet the requirements, and then they can be operated continuously.
