Stainless Steel Industrial Flanges

An SS flange is a stainless steel flange used to connect, isolate, or provide access within piping and process systems. Stainless steel options are included in Twinco Industrial’s flange and blind flange range, alongside carbon steel, alloy steel, duplex, and nickel alloys. Available configurations include weld neck, slip-on, blind, lap joint, socket weld, threaded, and API types.

The product information lists weld neck, slip-on, blind, lap joint, socket weld, threaded, and API flange types. Rental blind flanges are also available with raised face, flat face, RTJ, and seal ring groove faces. The appropriate configuration depends on the piping connection, isolation or testing requirement, pressure class, and project specification.

The listed flange products are available through rental and purchase options. Rental blind flanges are suited to hydrostatic testing, vessel and process system isolation, maintenance shutdowns, and turnarounds. Purchase options support pipeline, industrial piping, construction, welding, and ongoing maintenance requirements. Availability should be confirmed for the required type, material, size, and specification.

The provided range includes sizes from ½ inch through 72 inches. Listed ASME pressure classes include 125#, 150, 300, 400, 600, 900, 1500, and 2500, depending on the product. API-rated options are also listed from 2,000 to 15,000 PSI. Confirm compatibility with the piping system and governing project requirements.

The product information lists stainless steel, carbon steel, alloy steel, duplex, and nickel alloys across the flange range. Rental blind flanges include stainless steel, carbon steel, and exotic material options. Material selection should follow the process conditions, piping specification, pressure requirements, and applicable engineering documentation for the intended application.

Listed applications include pipeline applications, industrial piping systems, hydrostatic testing, petrochemical projects, construction and welding, manufacturing maintenance, vessel and process system isolation, and shutdowns. Stainless steel flanges can support connection and isolation requirements where the specified material and configuration are suitable for the operating system and project documentation.
