Lightweight Flange Suppliers for Offshore Platforms

Offshore platform design lives and dies on weight, and the Desflex Compact Flange was built with exactly that constraint in mind, offering up to 88 percent weight saving compared with an equivalent ANSI flange of the same rating. For a 6 inch, 2500lb rated connection, that means moving from around 783lb for a standard ANSI flange with bolting down to roughly 188lb for the equivalent Desflex flange, a saving in the region of 76 percent on that single joint alone. Multiplied across the hundreds of flanged connections on a typical topside module, that weight saving translates directly into reduced structural steel, smaller cranes for installation, and lower transport costs getting the module offshore in the first place. The flange still meets ASME VIII Div 1 and Div 2 and carries Type Approval and a passed API fire test, so the weight saving does not come at the cost of code compliance or safety verification. Standard and swivel weld neck versions are both available in carbon, stainless, alloy or duplex steel to suit platform process conditions.
