Why is it important to protect the flange face?

The flange face is the gasket sealing surface of a flanged connection. That connection can be on a pipe spool, valve, vessel, and a multitude of other mechanical equipment. This surface is typically a machined surface where the gasket seats and seals the piping system connection.

Flange types

The most common type of flange is a RF or Raised Face Flange. There are several other types of flanges like an RTJ or Ring Type Joint, GrayLoc or CofferLok style flanges, and of course a flat face flange. While the design and application of each of these are different, they all have one thing in common. The machined surface of the gasket seating area is one of the most critical elements of your piping system and must be protected from mechanical damage and corrosion.

Preventing Flange Damage

A scratch, dint, ding, or excessive rust in this area can cause a failure of the flanged connection if not corrected before final bolting. It is not uncommon for thousands of flanges to need to be resurfaced on a project costing millions of dollars. But the greatest impact of flange damage on these projects is the delays to the construction schedule costing the owner-operator weeks, months, and sometimes years of lost revenue opportunity.

Protection of your flange faces is essential to your project's success. It’s where the magic happens. Get it right and you’ll be the Hero delivering your project on schedule. Get it wrong and you will be looking at project delays, cost overruns, and an unhappy client.
