Stainless plate flanges

Stainless plate flanges are a type of flange used in piping systems for connecting pipes, valves, fittings, and other equipment. They are flat, circular discs with bolt holes around the perimeter, allowing them to be bolted to the adjoining equipment or piping components. Here’s some information about stainless plate flanges:

  1. Material: Like other stainless steel flanges, stainless plate flanges are made from stainless steel, which offers excellent corrosion resistance, making them suitable for a wide range of applications, including those involving corrosive fluids or environments.

  2. Design: Stainless plate flanges have a flat, circular shape with a raised face or a flat face. The raised face helps to create a smooth sealing surface when compressed against a gasket. The flat face variant is used in applications where the mating flange or gasket does not require a raised surface.

  3. Bolt Holes: Stainless plate flanges have bolt holes drilled around the perimeter. The number and size of bolt holes depend on the flange’s size and pressure rating. These bolt holes allow the flange to be bolted securely to the mating flange or equipment.

  4. Types: Stainless plate flanges can come in various types, including slip-on plate flanges and blind plate flanges. Slip-on plate flanges are slipped over the pipe and then welded in place or bolted, while blind plate flanges are solid plates used to close the end of a pipe or vessel.

  5. Sizes and Ratings: Stainless plate flanges are available in a wide range of sizes and pressure ratings to suit different piping system requirements. They can range from small sizes for residential plumbing to large sizes for industrial applications. Pressure ratings typically conform to standards such as ANSI/ASME B16.5 or EN 1092-1.

  6. Applications: Stainless plate flanges are used in various industries and applications where corrosion resistance and durability are essential. They find applications in industries such as chemical processing, oil and gas, food and beverage, pharmaceuticals, water treatment, and HVAC systems.

  7. Standards: Stainless plate flanges are manufactured according to industry standards such as ANSI/ASME, EN, DIN, JIS, and BS, which specify dimensions, materials, tolerances, and testing requirements to ensure quality and interchangeability.

When selecting stainless plate flanges for a piping system, factors such as the application requirements, pressure and temperature conditions, compatibility with the piping system, and applicable standards should be considered to ensure proper performance and reliability.
