ANSI Flange refers to pipeline flanges manufactured according to standards set by the American National Standards Institute (ANSI), ensuring uniform dimensions, pressure ratings, and performance across industrial fluid systems. These flanges serve as critical connectors for pipes, valves, and equipment, enabling standardized, leak-tight connections in applications ranging from chemical processing to oil and gas industries.

Designed with precise dimensional specifications, Ansi Flanges feature consistent bolt hole patterns, Flange face finishes, and pressure classes (150#, 300#, 600#, etc.), allowing interchangeability between components from different manufacturers. Common types include ANSI Weld Neck Flanges with reinforced necks for high-pressure (300#+) systems, Slip-On Flanges for easy installation in low-pressure (150#) applications, and Blind Flanges to seal pipe ends. Socket Weld Flanges suit small-diameter high-pressure lines, while Lap Joint Flanges offer alignment flexibility.

Materials align with operational demands: carbon steel (A105) for general industrial use with oils, gases, or water; stainless steel (316) for corrosive media in chemical or marine environments; and alloy steel (A182 F22) for high-temperature systems like power plants. Gasket compatibility is critical, with ANSI standards specifying face types (raised face, flat face) to match gasket materials—rubber for low pressure, PTFE for chemicals, or metal for extreme conditions.

In system integration, ANSI flanges ensure seamless compatibility with ANSI-standard components: they pair with ANSI Valves (butterfly, gate) for controlled flow, connect to Bellow Expansion Joints to absorb thermal movement, and work with Flange Adaptors to bridge ANSI and non-ANSI systems. Dismantling Joints with ANSI flanges simplify maintenance in standardized pipelines.

Key advantages include global interchangeability, reliability, and safety. Standardized dimensions reduce installation errors, while pressure-class ratings ensure performance under specified conditions. They facilitate easy component replacement, minimizing downtime. By providing a universal connection framework, ANSI flanges form the backbone of North American industrial networks, ensuring efficient, compliant fluid transport across diverse high-pressure and high-temperature applications.

ANSI Flange

American standard flange is a part used to connect pipes and pipes, usually used in industrial piping systems. ‌ It can be made of carbon steel, stainless steel or alloy steel, and common manufacturing methods include forging and casting. American standard flange is called steel pipe flange in the American system. It is an important connection component in the pipeline system to ensure the sealing and connection of the pipeline. ‌American standard flange plays an important role in industrial applications and is usually used to connect the inlet and outlet of equipment, such as reducer flange. It is connected by bolts and gaskets to ensure the tight connection and sealing between pipelines or equipment. The thickness of flanges and the type of bolts used for different pressures are different. Usually, low-pressure pipelines use threaded flanges, while high-pressure pipelines use welded flanges.

Product Detail

The composition of American standard flange mainly includes flange body, bolts and nuts, gaskets and other accessories (if any). These parts work together to ensure the stability and sealing performance of American standard flanges in pipeline systems.

Used to connect pipes. Metal rings are usually made of steel materials, such as carbon steel, stainless steel or alloy steel, etc. The choice of material depends on the working pressure, temperature and characteristics of the medium.

The gasket is located between the two flanges and plays a sealing role. Gaskets are usually made of rubber, graphite, metal or other suitable materials to ensure an effective seal at the pipe joint.

Studs and nuts are used to connect the two flanges tightly together to maintain the sealing effect of the gasket. Studs and nuts are usually made of high-strength materials to ensure the firmness and reliability of the connection.
