A694 Carbon Steel Flanges Both carbon and alloy steel parts and materials for fittings, pipe flanges, and valves are covered under the A694 Specification standard. These parts are designed for high-pressure support by the department.
The Standard Specification of flanges is A694. The flanges involve carbon and alloy steel material for moderate and high-temperature services. In addition, it covers steel fittings of seamless and welded types. Flanges are applied in pressure pipelines and pressure vessel fabrications. The A694 Carbon Steel Flanges are covered with wrought carbon steel.
Also, it includes alloy steel fittings of seamless and welded construction. As we know, ASTM A694 Carbon steel pipe flanges are utilized in pressure piping and vessel fabrication during services at moderate and elevated temperatures. The most popular grade material is used for medium and high-temperature pipelines. W stands for weldable, P stands for pressure, and B stands for grade b, which refers to the minimum yield strength. It has a designation that covers wrought carbon steel and alloy steel fittings of seamless and welded construction.
It is generally used for pressure piping systems of moderate and high-temperature services. ASTM A694 is the standard of butt welding materiality, indicating the material properties of carbon steel and alloy steel. Carbon Steel Flanges are one of the steels in this standard. A694 Carbon Steel Flanges have a butt welding end and will be welded with stainless steel pipes. Also, the welded pipe of A694 Carbon Steel Flanges means the large flanges that are piece welded. Flanges are different types of weld neck flanges, slip-on flanges, blind flanges, socket weld flanges, weld joint flanges, etc.
Uses Of A694 Carbon Steel Flanges:-
The flanges are often used across the following applications: subsea oil and gas, hard work and cryogenic, gas injection, high temperature, and nuclear applications.
