stainless steel flanges


carbon steel flanges

Steel Flanges: ASME, ASTM, BS, DIN, 1/4" TO 60" , CL 150 LB , CL 300 LB , CL 600 LB, TO CL 2500 LB,RF,FF,

Steel flanges are commonly used in a variety of industries to connect or close the ends of pipes, valves or equipment. Flanges are available in different types, sizes and grades to suit specific applications.


Here are some key details about steel flanges:


1. Standards: Steel flanges are manufactured according to different standards including ASME (American Society of Mechanical Engineers), ASTM (American Society for Testing and Materials), BS (British Standards), and DIN (German Institute for Standardisation).


2. Range of sizes: Steel flanges are available in a wide range of sizes, typically from 1/4" to 60" in diameter. This allows for compatibility with a wide range of pipe sizes.


3. Pressure ratings: Flanges are designed to withstand different levels of pressure and are classified accordingly. Common pressure ratings include 150 LB, 300 LB, 600 LB, and up to 2500 LB. Pressure ratings represent the maximum pressure that a flange can withstand.


4. End Types: Depending on the type of connection, flanges can have different end types. The most common types are raised face (RF) and flat face (FF). RF flanges have a raised sealing face, while FF flanges have a flat face.


It is important to note that the specific requirements for flanges will vary depending on the application and industry standards. Factors such as material compatibility, temperature, pressure and intended use should be considered when selecting a flange.
