For this DN150 ANSI B16.5 A106 carbon steel polished blind-flange enquiry, verify the offered material before accepting a natural-gas specification. Actual variants list Polypropylene or PP, while the title says carbon steel. The supplied material remains unresolved until the supplier identifies the component and provides traceable records.

Allocate A106 and DN150 to the actual component

A106 appears in the title rather than as a separate material option. Confirm the governing material document, edition, full grade, condition and accepted certification; do not treat that reference as automatic flange conformity. Request production records for the table’s Mould wording.

Both variants have size None. Confirm what DN150 describes, individual availability and an approved closure drawing. The repeated one-eighth-to6-inch entries are not verified overall or bolt-hole dimensions. Specify outside diameter, thickness, facing dimensions/finish, bolt circle, hole count/diameter and tolerances.

Confirm the class basis and mating bolted joint

Identify the B16.5 edition and applicable selected size/material/class provisions. Use the table’s Pipe Class150 to clarify the title’s class wording, with documented confirmation rather than an operating-pressure conversion. Low Pressure is qualitative; obtain the accepted material/document/temperature basis and numerical duty.

Agree the mating flange, gasket and fasteners against the actual drawing. Clarify generic Equal and NPT OR BSPT entries without assuming threaded closure features. Specify polished surfaces and finish inspection criteria rather than inferring corrosion resistance from Polishing wording.

Approve the complete closure for the actual gas

State gas composition, pressure, temperature, cycling, external loads and compatibility requirements. Natural-gas title context does not establish universal approval. Agree installation and relevant leak/inspection criteria, material/manufacturing/dimensional/class documents, marking, confirmed supply, quotation scope and three-year warranty/customization terms.
