2 Threaded 150# Raised Face Flanges

A two-holed flange generally refers to a flange with two bolt holes or a two-hole drilling arrangement. The term can be used informally and may not fully define the flange standard, size, or bolt pattern. Confirm the flange dimensions, pressure class, facing, and applicable specification before ordering or mating it with another flange.

Bolt size is determined by the flange standard, nominal pipe size, pressure class, bolt-hole diameter, and mating flange configuration. A reference to a “2-flange” alone is not enough to identify the correct bolting. Confirm the complete flange specification and consult the applicable dimensional standard or Twinco Industrial sales team before purchase.

150# raised face flanges are used to join and seal sections of industrial piping systems. The raised face provides a gasket seating surface, while the threaded design connects without welding. Applications listed for this category include pipelines, industrial piping systems, hydrostatic testing, petrochemical projects, construction and welding, and manufacturing maintenance.

The listed material options include carbon steel, stainless steel, alloy steel, and nickel alloys. Material selection should match the piping service, operating conditions, corrosion requirements, and project specification. Twinco Industrial product information also identifies duplex among its broader flange material options, so availability should be confirmed for the required configuration.

Yes. The product information identifies both rental and purchase options. Rental can support temporary hydrostatic testing, maintenance, shutdown, construction, or isolation requirements, while purchasing may suit recurring industrial piping and project needs. Confirm the required size, material, pressure class, facing, quantity, and availability when requesting a quote.

The listed certification and specification data includes the ASME B16 Series and API Standards. Product information also identifies ASME B16.5 and ASME B16.47 Series A and B for the broader flange offering. Confirm the applicable standard for the specific threaded, raised face, 150# configuration and project requirements before placing an order.
