Butt Weld Pipe Fittings

The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors. WHAT IS ANSI? ANSI-approved flanges are used for the industrial market which handles gas, air and steam process systems. Originally formed in 1918, the American National Standards Institute is headquartered in Washington, DC, and is widely recognized as the American organization responsible for overseeing the national standards and conformity assessment system for products, services, processes, systems, and personnel. ANSI works domestically with American government agencies and organizations, as well as with international entities, to make ANSI standards useful around the world. Prior to the creation of ANSI, standards for engineering and equipment such as flanges were developed by the American Institute of Electrical Engineers (AIEE or IEEE), the American Society of Mechanical Engineers (ASME), the American Institute of Mi...

The American National Standard Institute, ANSI, has been overseeing guidelines and standards for products manufactured through several sectors. ANSI-approved flanges are used for the industrial market which handles gas, air and steam process systems. Series A 150 & 300 Blind Flange Series A 400, 600 & 900 Blind Flange ANSI Series A Weld Neck Flange Series A 400, 600 & 900 Weld Neck Flange Purpose Flanges are used to attach a series of pipes or other flanges together. Some flanges, such as in the oil and gas sector, are required to sustain under high amounts of pressure. ASNI provides standards to flange manufactures to test flanges before they can be marketed to a particular sector. Significance ANSI provides standards on flanges depending upon pressure in pounds per second per inch (PSI), according to size in inches of the flange. Pressure and size are dependent upon whether the flange is welded to the pipe, threaded or bolted. Considerations Depending on the material the ...
