Each gasket comes with enough bolts and nuts to create a connection between two steel pipe flanges Commonly called full face gaskets they cover the entire face of flat surface pipe flanges and align with the bolt holes They re made from blended aramid fiber Buna N rubber and resist oil water and aliphatic hydrocarbons such as ethylene
Insulating Kits for Bolts of Piping Flanges Insulation kits are designed to prevent galvanic corrosion between flanges of dissimilar metals for example a carbon steel flange bolted to a stainless steel flange A conducting liquid such as water must be present between the two flanges for galvainc corrosion to occur
Bolt Stud Tightening Pattern One of the most difficult jobs is to produce the correct assembly pressure on the gasket low enough to avoid damaging the gasket but high enough to prevent a
