Super Duplex Header Plug

These header plugs are commonly installed in heat exchanger header boxes to close or isolate individual tubes. They are useful during maintenance operations when a leaking tube needs to be taken out of service, while also providing access for inspection and cleaning. Their robust construction makes them suitable for demanding pressure and temperature conditions.

At Unifit Metal Alloys, we supply Super Duplex Header Plugs in various sizes, dimensions, shoulder designs and thread configurations. Standard products as well as customized components can be supplied according to header box dimensions, tube specifications, customer drawings and project requirements. Our Super Duplex Header Plugs are used across oil and gas, offshore and marine, chemical processing, petrochemical, refinery, power generation and heat-transfer industries. They are particularly suitable for systems where conventional materials may not provide adequate resistance to chloride-containing or highly corrosive environments.
