In which cases insulated flange is required

Usually, there are some dangerous factors in pipeline connection, including leakage, galvanic corrosion and static electricity. These are signs of accidents. Therefore, ordinary flange connection is not enough. It is necessary to use insulated flange with insulation characteristics, which is used in the environment of insulated flange shared by everyone.

In which cases insulated flange is required

The use of insulating flange can be divided into three situations: galvanic corrosion: the contact of different metals will accelerate the corrosion of metals, and the stability is poor, which is called galvanic corrosion. Galvanic corrosion occurs between metal flanges made of different materials. Galvanic corrosion can be eliminated by using a suitable insulating flange kit. Second, cathodic protection: in order to ensure the effectiveness of cathodic protection of stainless steel pipeline, the pipeline must be divided into manageable lengths. The sealing and insulation of stainless steel flange can be ensured by using insulating flange kit. Third, electrostatic isolation: when using pipelines to transport flammable and explosive media, if the explosion conditions are met, it will be ignited due to electrostatic, cathodic protection system or eddy current. The use of insulated flange kits can reduce or eliminate this potential hazard.
