Easy bolt-holealignment

The RSR Swivel-Ring Flange sets consist of a 360°rotation outer ring and ahub, the design make it easy to align the bolt holes when attaching to a matingstandard flange. For subsea applications, this capability is important whenalign and make up the flange connections; it will save much time forinstallation, save time means save money. Swivel-Ring Flanges can be designedfor most size and pressure rating as per ASME B16.5, API 6A, API 17D, MSS SP-44or Norsok L-005. Swivel-Ring Flanges raw materials are available in ASTM A105, A694 F52 toF65, A350 LF2, AISI 4130, and A182 F51 & F53. Also we can supply flangeswith other materials such as A694 F70, AISI 8630 and so on. Reference,dimensional data for ANSI and MSS RTJ Swivel-Ring Flanges are given in thetables below.

Design Specifications

Swivel-Ring Flanges are designed in accordance with ASME Pressure VesselCode, Section VIII, Division 2, DNV OS F101, API 6A and API 17D unlessotherwise specified, and applicable sections of the flange specification towhich it will mate. Finite element analysis: ANSYS FEA to verify the designintegrity before manufacture
