High Fatigue Performance Flange Suppliers

One of the stated advantages of the Desflex Compact Flange over a conventional ANSI flange is superior mechanical strength and fatigue performance, a benefit that matters most on pipework subject to repeated pressure cycling, vibration or thermal expansion and contraction over its service life. The flange's weld neck construction and patented spherical nut and toe design work together to reduce the stress concentrations and bolt bending that drive fatigue cracking in conventional flanged joints. Destec supplies the flange across the full range of standard sizes and pressure ratings, in carbon, stainless, alloy and duplex steels, so the fatigue performance benefit is available regardless of the specific material or duty the flange is specified for. This makes the Desflex flange a practical upgrade wherever a conventional ANSI flange has a history of fatigue-related failures or where a new project anticipates significant cyclic loading over its design life.
