Square Flanges Manufacturer

Specialized Square Flanges Manufacturer, SHAB, SSAB, KAB Square Flange Dimensions.

Marcel Piping Projects Supply PVT LTD is one of the oldest manufacturers, stockists, suppliers, and exporters of Square Flanges in India. Square flanges are used in hydraulic systems to connect a pipe to element or a pipe to pipe connection. As the name implies, square flanges are exactly shaped. It makes in accordance to different norms based on varied countries, square flanges come in different pressure range in order to fulfill their purpose. A complete set of square flanges correspond of the female flange, male flange, and bolts. The female flange is associated as part A. The male flange is linked as part B. And the complete set is AB.

With Square Flange, you can insure seamless inflow of liquid through pipe or other hydraulic system. Square flanges come in different sizes from 1/4 inch to 6 inch. The normal sizes for system installation are 1/2 to 2 inches. Square Flange made in accord to JIS F7806 and JIS B2291 standard is a connecting piece that link JIS nominal snooze size pipes together and has a working pressure of up to 210 kgf / cm2. This is other to 210 Bar, or 21 MPA. They’re generally used in high pressure systems like as hydraulic for up to PSI working pressure.

Square flange end connection is welding type and it’s called as socket weld. The pipe has to fit in to the recessed area of the steel flange, so as to have plain end. Other connections can be customized upon request. A complete set of square flanges included 5 important parts. It’s 1 piece of female side, marker as A side, 1 piece of male side, marker as B side, 4 pieces of hexagon cap screws, 1 piece of NBR70 /90 oring and 4 pieces of hexagon nut. Hexagon nuts are paired with hexagon bolts to use in tensing up both male and female sides.

Square Flange Dimensions
SHAB, SSAB, LSA

  • SHAB Flange: it is the most common used in the industry, it works in maximum pressure 210kg/cm² and it is used together with hexagon bolts.
  • SSAB Flange: it works under pressure 210kg/cm² too. However, the body is smaller compared to SHAB and it is used together with Allan cap screws.
  • KAB Flange: It has similar configuration to SHAB but having a main difference of higher pressure rating for either 280kg/cm² and 350kg/cm².
  • Square Blind Flanges are used to close the end flow of the system connection.
