Anmerican Standard Flanges

Pipe Flanges are widely used as a popular category of pipe fittings. A flange is used to mechanically connect two pipes together. It can also be used to mechanically connect a pipe to a tee, valve, choke or any other piece of equipment. Flanges are available in round, square, and rectangular shapes. In some cases, flanges are usually in the shape of a ring or a plate to form a rim at the end of a pipe when fastened to the pipe. This is an example of closet flange. A flange can also be a plate for covering or closing the end of a pipe. This is a blind flange. Thus, flanges are considered to be projecting or internal components which are used to support mechanical parts. They are like rims which are used to strengthen the mechanical part or they are a means of attaching that part to another part or surface.

Designs of flanges:
A wide variety of flange designs are available. They are available in various shapes and sizes. Some of the popular designs are as follows:

  • Butt weld
  • Socket weld
  • Captive
  • Split
  • Square
  • Round
  • Rectangle etc.

Custom shapes and sizes are also manufactured by numerous manufacturers. Various pipe flanges include machining details such as gasket surfaces, facing details, non-standard drilling, bevel and radius edges, o-ring grooves and raised or recessed faces. Some typical designs on flanges faces are shown below.

ASTM A182 F321H Blind Flange is a high-strength, corrosion-resistant carbon steel blind flange that adheres to the specifications outlined in ASTM A182, which is a standard for wrought austenitic stainless steel pipe flanges and related components. The "F321H" designation indicates that the material has been alloyed with higher levels of nickel and molybdenum compared to the base F304 grade, providing enhanced resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking in harsher environments.

Key features of ASTM A182 F321H Blind Flange include:

1. Material: Austenitic stainless steel, specifically 321H (UNS S32109) – a 18-8 type stainless steel with higher nickel and molybdenum content.
2. Corrosion resistance: Improved resistance to chloride-induced pitting and crevice corrosion, as well as better resistance to sulfuric acid and hydrochloric acid environments.
3. Heat treatment: The material can be heat-treated to achieve higher strength levels than F304 without significant loss of toughness or ductility.
4. Mechanical properties: Provides excellent mechanical strength, creep resistance, and weldability.
5. Applications: Commonly used in industries such as chemical processing, oil and gas, petrochemicals, power generation, and marine environments where harsh chemicals or elevated temperatures are present.

When selecting an ASTM A182 F321H Blind Flange, it's essential to consider the specific application requirements, including temperature, pressure ratings, and the chemical compatibility of the service medium. Proper selection and installation are crucial for ensuring the integrity and longevity of the component.
