Cromwell Distribution is a Dominant and Expert Stockist of high quality ASME/ANSI/DIN industrial Square flanges . We offer immediate delivery programs for standard size of carbon steel Square flanges and stainless steel Square flanges. Square Square flanges in special stainless steel grades, nickel alloy and alloy steel can be supplied with just in time programs.
Commonly referred as blanking flanges, Square pipe flanges are widely used in high pressure applications. Square flanges are generally used to seal the end of a piping system to prevent flow of liquids or gases. The use of Square flanges allows ease of access to a piping system once it has been closed.
Our Square flanges are available with raised or RTJ faces and also with female threads. Square flanges can be supplied with or without hub as per the customer requirements. We offer Square Square flanges at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.
Square Flange made in accordance to JIS B2291 standard is a connecting piece that links JIS (Japanese Industrial Standards) nominal bore size pipes together and has a working pressure of up to 210kgf/cm2. This is equivalent to 210 Bar, or 21MPa. They are usually used in high-pressure systems such as hydraulic and steam lines for up to 3,000 PSI working pressure. There 3 types of Square flanges i.e. SHAB, SSAB, LSA.
