Alloy Steel Compact Flange Suppliers

Destec supplies the Desflex Compact Flange in alloy steel for applications operating at elevated temperature or pressure where carbon or standard stainless steel would not provide sufficient strength or creep resistance over the flange's service life. Alloy steel flanges are available in both standard and swivel weld neck configurations, built to the same ASME VIII Div 1 and Div 2 compliance, Type Approval status and passed API fire test as the rest of the Desflex range. The patented spherical nut and toe design continues to control bolt stress and flange rotation regardless of the base material, so the alloy steel flange delivers the same weight saving and fatigue performance benefits seen across carbon, stainless and duplex versions. Alloy steel Desflex flanges suit high temperature process pipework in refineries, power generation and petrochemical plant, where material creep and long-term strength retention are as important as the initial pressure rating.
