5 Inch Threaded Class 150 Carbon Steel Flanges

Twinco Industrial lists Weld Neck, Slip-On, Blind, Lap Joint, Socket Weld, Threaded, and API flange types. The available product information also identifies Flanges & Blinds as the product type. Customers can request assistance comparing the connection style, pressure class, material, and applicable standard for a specific piping, testing, or maintenance requirement.

The product information lists both rental and purchase ownership options. Rental can support hydrostatic testing, maintenance, shutdown, and construction activities where equipment or components are needed for a project. Purchase may suit recurring industrial piping requirements. Availability and commercial terms are not specified, so customers should request a quote for the required configuration.

The listed certification standards and product information reference the ASME B16 Series, including ASME B16.5 and ASME B16.47 Series A and B, as well as API Standards. The correct standard depends on the flange type, size, pressure class, and project specification. Confirm the governing requirement before ordering or using the component.

The listed material options include Carbon Steel, Stainless Steel, Alloy Steel, Duplex, and Nickel Alloys. Material selection should reflect the piping medium, operating conditions, corrosion considerations, design requirements, and project specification. This page focuses on Carbon Steel flanges, while other material options may be available across the broader flange range.

Twinco Industrial lists flange sizes from ½″ through 72″ and ASME pressure classes of 150, 300, 400, 600, 900, 1500, and 2500. API ratings from 2,000–15,000 PSI are also listed for applicable products. Confirm the exact size, class, flange type, standard, and material required for the application before requesting availability.

Yes. Hydrostatic testing is specifically listed as an application, along with pipeline work, industrial piping, maintenance, and construction. Threaded flanges may be selected for compatible piping configurations, while blind flanges and related components can support isolation requirements. Twinco Industrial also lists rental options, allowing customers to request a configuration suited to the testing or maintenance task.
