Square Flange

About Square Flange

Square Flanges are compact flanges designed for hydraulic and pneumatic pipeline systems where space is limited. Manufactured in accordance with JIS B2291 / ISO standards, these flanges are forged from Carbon Steel, Mild Steel, or Stainless Steel to withstand high-pressure conditions. Square flanges are widely used in hydraulic lines, shipbuilding, and machine tool piping because of their robust design, easy installation, and reliable leak-proof performance.
