This metal ring joint gasket listing references ASME B16.20 for pipeline flange enquiries. Class 125 appears in both the title and table, while the available material is generic Stainless Steel. Confirm the actual ring and flange combination before relying on the source wording for a purchase specification.

Reconcile the flange designation and ring selection

Provide the mating flange standard, designation and groove drawing together with the required ring identification. Check the ring profile, dimensions and tolerances against that actual groove. Class 125 wording alone does not identify a compatible combination, and it must not be read as a 125 psi pressure limit.

Clarify the role of the 10 mm pipe-size option and the unit and meaning of the 1/16 mounting-hole entry. Neither provides the complete sealing dimensions. The generic Female and Equal fields also need explanation against the approved ring drawing rather than interpretation as a defined connection geometry.

Establish material and conformity evidence

Request the exact stainless alloy, material condition and hardness requirements for the selected ring. Obtain traceability, dimensional inspection and marking records. Confirm the applicable ASME B16.20 edition and requirements for the proposed design; the standard reference in the title is not a product conformity certificate.

Seamless and Smooth wording does not establish the required production evidence or numerical finish. Agree the sealing surface criteria and inspect the mating components according to the actual specification. Do not assume that a general stainless material label determines every property required by the joint design.

Define service and assembled joint acceptance

State the conveyed fluid, contaminants, pressure, temperature, cycles and design loads. High-pressure seal wording gives no allowable envelope or guaranteed leakage result. Review the flange, ring and bolting requirements together, then confirm the assembly specification, acceptance documents, quantity, preservation and delivery. Broad resistance labels require assessment for the selected service.
