Alloy Insulating Flange Corrosion Category
Dec 16, 2016

Insulating flange is designed to prevent material chemical reaction or is damage caused by physical changes. Alloy flange features so you can avoid material or medium damage. But due to the complexity of the condition can also cause corrosion of the joint, usually so classified:

Alloy insulating flange corrosion damage can be divided into: local metal corrosion or peeling, corrosion, cracking or corrosion products have harmful effects on the environment.

Alloy insulating flange local forms of erosion corrosion, pitting, microcrystalline structure, material is very small areas of selective dissolution or cracking. Most important are uniform corrosion, pitting corrosion, pitting corrosion, crevice corrosion, Crystal, as well as with corrosion-stress generated by the mechanical action of corrosion and corrosion fatigue.

Alloy flange which is most worrying. Vast majority of corrosion pitting. Uniform corrosion usually occurs, but corrosion corrosion consequences rarely.
