Removing a stuck gasket from the flange surface can be a tedious and labour intensive task that can end up damaging the flange surfaces. The amount of time spent on cleaning flanges can be significant, and in many services, the plant must remain off-line longer while the gaskets are removed, resulting in a loss of production Time [min] Time [min] FIRE SAFE PRODUCT Complies to Fire Safe Test DVGW VP 41 By using we enable you to optimize your resources and shorten your maintenance duration. The state of the gasket after opening the joint also shows the superb thermo mechanical properties and fire safety of.
