This flange enquiry centres on the ASME B16.5, SS316L and Class 150 requirements named in the source information. The next step is to identify the required construction and connect it to a specific drawing and material record. Flange type, grade and pressure class need separate confirmation before the proposed item can be assessed as part of an assembled joint.
Choose the required flange function
State whether the flange must receive a pipe through a slip-on bore, provide a socket-weld interface or close an opening. Request a drawing of the selected construction instead of choosing from a general image alone. For a pipe connection, include the mating pipe outside diameter, wall dimensions and joining requirements. Explain what the millimetre size option represents and confirm the individual nominal size rather than assuming the option value defines the complete interface.
Match SS316L and the bolted interface
Specify the exact material designation and governing material specification for the stainless-steel requirement. Ask for traceable grade and manufacturing records for that item; the carbon-steel alternatives require their own material assessment. Define the B16.5 edition, required Class 150 and facing, then check flange thickness, bolt circle, hole pattern and mating dimensions together. A generic finish or mounting-hole field cannot establish that the complete pattern matches the adjoining flange.
Assess the complete connection
Provide the fluid, pressure and temperature along with sealing and fabrication requirements. Review the material-dependent rating and joint evidence for the actual configuration, rather than treating a class label as a direct operating-pressure statement. Where forged manufacture is required, request production and inspection records tied to the selected model. This combination of construction, traceable material, mating geometry and duty information gives the enquiry a clear basis for technical acceptance.
