STYLE R
nnnnThe Ring Type Joint was initially developed for
nnnnhigh pressure/temperature applications found in
nnnnthe petroleum industry and is primarily used in
nnnnthe oil field on drilling and completion
nnnnequipment. However, today this product range
nnnncan also be found on valves and pipework
nnnnassemblies, along with some high integrity
nnnnpressure vessel joints.
nnnnStandard Style R Ring Type Joints are
nnnnmanufactured in accordance with both API 6A
nnnnand ASME B 16.20 size/ratings. Available in
nnnnboth oval and octagonal configurations, both
nnnntypes are interchangeable on the modern
nnnnoctagonal type grooved flanges.
nnnnAs with all solid metal Ring Type Joints including Style R, it is
nnnnrecommended to replace the ring when flange connection is
nnnnbroken.
