There are four kinds of flange insulation gasket kits.Type D,E ,O and F.Now,we introduce you more about type D flange insualtion gasket kit.
What is Spiral Wound Gasket (SWG)?Do you know?
Flange Insulation Kits are the most widely used form of controlling losses due to corrosion.They can be used to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants,to increase the effectiveness of cathodic protection systems and confine or eliminate electrolytic corrosion.
Uneven pressing force is caused by a variety of factors, first is the human factor: asymmetric construction of the preload bolt, this factor can eliminate construction; theory on the flange pressed, the sealing surface is absolutely parallel to the practice, however, the centerline of a pipeline can not be absolutely concentric, and thus tighten the bolts on the flange moment, so that the flange discontinuity.
A common improvement is an inner compression ring. A compression ring allows for higher flange compression while preventing gasket failure. The effects of a compression ring are minimal and generally are just used when the standard design experiences a high rate of failure.
A flange gasket is a type of gasket made to fit between two sections of pipe that are flared to provide higher surface area.
