RF Slip-On Flanges in Carbon and Stainless Steel

RF slip-on flanges are used to connect piping components where the flange slips over the pipe and is secured by welding. They support industrial piping systems, pipeline applications, hydrostatic testing, petrochemical projects, construction, welding, and manufacturing maintenance. The correct selection depends on the piping specification, required material, pressure class, dimensions, and applicable ASME or API requirements.

The supplied product information identifies carbon steel and stainless steel for this category. The broader flange inventory also lists alloy steel, duplex, and nickel alloys. Material selection should follow the project specification and service conditions, including compatibility, temperature, pressure, corrosion considerations, and any documentation requirements. Request confirmation of available material grades and documentation with your quotation.

The product information references ASME B16.5 and ASME B16.47 Series A and B standards, along with the ASME B16 Series and API Standards. API ratings from 2,000–15,000 PSI are also identified for the broader flange offering. Confirm the required standard, flange dimensions, pressure class, facing, and material against the project specification before purchase or rental.

The broader flange product information lists sizes from ½″ through 72″ and ASME pressure classes of 150, 300, 400, 600, 900, 1500, and 2500. Availability for RF slip-on flanges may vary by material, size, class, and sourcing option. Provide the required nominal size, pressure class, material, and standard so the appropriate inventory can be checked.

Yes. The product information identifies both rental and purchase options. Rental can support hydrostatic testing, maintenance, shutdowns, construction, and other project-specific requirements, while purchase may suit recurring piping and fabrication needs. Availability depends on the requested specification and inventory. Include quantity, size, material, pressure class, application, and required date when requesting a quote.

Provide the flange type, nominal size, material, pressure class or API rating, applicable standard, quantity, and whether the requirement is for rental or purchase. Also identify the application, such as pipeline work, hydrostatic testing, petrochemical construction, welding, or maintenance. These details help Twinco Industrial review the specification and identify suitable inventory or sourcing options.
