This oil and gas piping listing identifies a ring type joint gasket, or RTJ, with an ASME B16.20 reference. The available option records generic Stainless Steel rather than an exact alloy or ring designation. Establish the required ring and mating flange details before treating the listing as a complete joint specification.

Identify the ring and its matching groove

Supply the ring designation, required profile and the flange or equipment drawing. Confirm the dimensions and tolerances that govern seating in the actual groove. The 10 mm pipe-size option does not establish the ring thickness, section or sealing diameter, and the separate 1/16 hole entry lacks a stated unit.

Ask the supplier to explain the generic Female and Equal fields against the selected RTJ design. Smooth wording does not specify a numerical surface finish. Review ring dimensions, groove condition and any finish requirements together, using the actual joint specification rather than a general visual resemblance.

Check material and pipeline duty

Obtain the stainless alloy, material condition, relevant hardness evidence and traceability for the proposed ring. The listing does not identify a specific stainless grade. Confirm the applicable ASME B16.20 edition, marking and inspection requirements against that ring, including any project requirements beyond the standard reference.

Describe the transported oil or gas, water and contaminants, pressure, temperature and operating cycles. High-pressure resistant wording supplies no allowable numerical limit. Pipe Class 125 also does not establish an assembled RTJ joint rating, and the broad corrosion-resistant label does not demonstrate sour-service or hydrogen qualification.

Agree joint acceptance and supply records

Review the mating flange, groove and bolting requirements with the responsible specification. Obtain dimensional inspection and material documentation before approving supply. Confirm quantity, preservation, marking and delivery timing, and agree any assembly procedure for the actual components rather than using a universal tightening value.
