This ASME B16.5 A105 Class 150 carbon steel blind flange enquiry focuses on a specified piping closure. Stainless steel alternatives are also selectable. Confirm the actual centre configuration and material records for the chosen variant before approving a blind flange for service.

Blind face, possible ports and mating dimensions

Request a selected-item drawing showing the required solid centre and any deliberately specified port. A Reducing entry does not establish the intended closure geometry. The gallery contains solid-centre and hubbed open-centre examples, so appearance alone cannot identify the supplied subtype. An NPT entry also does not prove a threaded port in a blind face.

Map the labels 10 mm, 12 mm, 14 mm, 50 mm and 30 mm to actual nominal sizes and flange dimensions. Confirm outside diameter, thickness, facing, bolt circle, hole count and hole diameter against the mating flange. The listed length of 4 inches, height of 9 without a unit and mounting-hole diameter of 0.25 inches need an explicit selected-item relationship.

A105 material evidence and closure service

Obtain the exact material specification, grade and traceability. The A105 carbon steel enquiry does not assign that designation to stainless alternatives or certify every carbon steel selection. Technic Other leaves the actual manufacturing route unqualified; Smooth does not establish measured sealing-face roughness.

Request the applicable complete B16.5 specification edition and dimensional conformity evidence. Evaluate Class 150 and Low Pressure wording with the actual material, temperature, gasket, bolting and closure design. Neither establishes a fixed working pressure. Flexibility, chemical resistance, corrosion resistance and UV resistance require evidence for the actual design and exposure.

Documents for the selected blind closure

Provide the centre and port drawing, nominal size, facing, mating flange and required gasket/bolting details. State operating medium, pressure, temperature and environmental exposure. Request material traceability and relevant inspection records, then assess the proposed closure against the documented piping requirements.
