Specification of Flange 

The specified ASTM Standard Specification for Nickel Alloy 400 Flanges is ASTM B 564 with manufacturing standard such as ANSI/ASME B16.5, B16.47, BS4504, B 16.47 Series A & B, BS 10, EN-1092, DIN, etc.

According to  application and uses in pipes and tubes Alloy 400 flanges are broadly grouped into different sort, for example, Welding Neck Flange(WNF) & Long Welding Neck Flange(LWNF), Slip-on Flange(SOF), Lap Joint Flange(LJW), Blind Flange, Socket Welding Flange (SWF), Threaded Flange(THW), Plate Flange.

Monel 400 Flange for the most part has different  face type, for example, Flat Face (FF), Raised Face (RF), Ring Type Joint (RTJ), blind flange, with various class rating as 50 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16,din 2.4856 , 25, 40 & ANSI B16.5.

Specification of Fittings
