Forged Steel Slip-On Raised Face Flanges

Use a slip-on flange when the piping design calls for a flange that fits over the pipe and is joined through welding. Slip-on configurations are commonly considered for industrial piping, pipeline, construction, and maintenance work. Selection should account for the specified material, dimensions, pressure class, service conditions, welding requirements, and applicable ASME or API standards.

A full-face gasket is generally selected for full-face flange arrangements, while raised face flanges typically use a gasket sized for the raised sealing surface. Using an incompatible gasket can affect compression, sealing, and bolting. Verify the flange facing, gasket type, pressure class, dimensions, and project specifications with the responsible engineer or qualified supplier before installation.

Available material options include carbon steel, stainless steel, alloy steel, duplex, and nickel alloys. The supplied product information identifies carbon steel, stainless steel, alloy steel, and nickel alloys for this category, while the broader inventory also lists duplex. Material selection should follow the piping specification, process conditions, applicable standards, and required documentation.

The product information identifies ASME B16 Series and API Standards as applicable certification standards. It also lists ASME B16.5 and ASME B16.47 Series A and B standards among the available specifications. Confirm the required standard, pressure class, dimensions, facing, material, and documentation against the project material specification before ordering.

Twinco Industrial offers rental and purchase options across its flange and industrial component solutions. Rental can support hydrostatic testing, maintenance, shutdowns, and construction requirements, while purchase may suit recurring or permanent piping needs. Availability depends on the requested configuration, material, size, pressure class, and project requirements, so provide those details when requesting a quote.

These flanges are relevant to pipeline applications, industrial piping systems, hydrostatic testing, petrochemical projects, construction and welding, and manufacturing maintenance. The right selection depends on the connection design, pipe and flange specifications, service conditions, pressure class, material, and applicable ASME or API requirements. Twinco can review the application details when preparing a quote.
