MACHINED END CAPS
DUPLEX and SUPERDUPLEX
Pressure Rating : 1200 psi (82 bar) with schedule 40s pipe (special alloys) with cut groove only – all sizes.
Description
Duplex 2205 and Super Duplex 2507 conform to ASTM A240
Duplex +
Duplex stainless steel is highly resistant to chloride corrosion because of its metallurgy and microstructure. Used for high pressure couplings for seawater installation our duplex alloy is made of two metallurgical phases with each their role to play in the efficiency of the couplings.
The two phases are homogenized to form a metallic composite analogue to epoxy/glass composite. Our duplex is highly resistant to corrosion and offers twice the tensile and yield strength compared to stainless steel 316. Our duplex alloy is CE8MN and offers better mechanical properties when compared to conventional 316L stainless steel.
Super Duplex +
Our couplings can also be produced using a super duplex material, whichoffers even higher corrosion resistance than duplex, and is very similar to alloys 2507 and Zeron 100 which are commonly used for seawater piping.
Made of super duplex stainless steel CE8MN alloy, our couplings are austenitic-ferritic stainless steel and highly resistant to chloride stress corrosion. Super duplex grade of stainless also offers higher strength and better mechanical properties than duplex stainless steel
Option
As an option, these end caps can be specified with CE3MN super duplex material, which offers a slightly higher Pitting Resistance Equivalent Number (PREN).
