Does the flange sealing surface need to be coated with grease?

Reply #22021-05-07

It can’t be generalized; there are certain industries or manufacturing processes in which coating is not possible, as grease constitutes an impurity for the product

Regardless of the product, can grease serve as a sealant?

Is it possible to improve sealing without using grease?

Reply #52021-05-08

Grease is often used on metal wound gaskets; it can fill the gaps in these gaskets and improve their sealing performance

It’s not necessary; especially in areas where cleanliness is required and in some chemical plants, it is not allowed to apply grease!
