Duplex Header Plugs are high-performance sealing components engineered for use in extreme industrial environments where mechanical strength, corrosion resistance, and long service life are critical. These plugs are primarily used to seal tube sheet and header openings in heat exchangers, pressure vessels, and high-pressure piping systems.
Manufactured from advanced duplex stainless steel alloys, duplex plugs combine the best properties of austenitic and ferritic stainless steels. This dual-phase microstructure provides superior tensile strength, excellent resistance to pitting and crevice corrosion, and outstanding performance against stress corrosion cracking.
Jade Alloys supplies precision-engineered Duplex Steel Header Plugs that conform to international quality standards and are suitable for aggressive chemical, marine, offshore, and high-temperature applications. Our duplex plugs are widely used where conventional stainless steel plugs fail due to corrosion or pressure limitations.

Duplex Steel Header Plugs Grades
Our most widely supplied grade is:
Duplex 2205 Header Plug (UNS S32205 / UNS S31803)
Duplex 2205 Header Plugs are the industry standard for applications requiring higher mechanical strength and superior resistance to chloride-induced corrosion compared to conventional austenitic stainless steels. The dual-phase microstructure (austenitic + ferritic) of Duplex 2205 provides excellent resistance to stress corrosion cracking, pitting, and crevice corrosion.
