Prithviraj Industries manufactures 6B and 6BX flanges in various sizes & pressure ratings as per API 6A. Most common material is low alloy steel AISI 4130. AISI 410 or UNS 31803 which are used for some of the critical services. Application of CRA (SS 316 or Nickel alloy 625) enhance the corrosion resistance ability of ring groove, thus enhancing the product life.
6B flanges are ring joint type and are not designed for face-to-face make-up. Bolting force acts on the metallic ring gasket. 6B flanges are of through bolted or studded design. R or RX are ring groove type.
Types Of 6B Flanges:
6BX flanges are ring joint type and has a raised face. Joining make-up bolting force acts on the raised face of the flange when the gasket is properly seated. This support prevents damage to the flange or gasket from excessive bolt torque. Therefore 6BX connection has raised face. Type 6BX flanges are of through bolted or studded design. Face-to-face contact is not necessary for the proper functioning of the 6BX flange. 6BX flanges have BX ring gasket groove.
Types Of 6BX Flanges:
