Square Flanges is widely manufactured and supplied to countries like UAE, Saudi Arabia, Kuwait, Qatar, Egypt, Turkey, Oman, Africa, Malaysia & many countries in USA & Europe. Since 1992 Pipe Fitting Supplier are providing this effective product service with national and internal standards of procedures for the fulfillment of spreading high quality stainless steel products in various industries like gas, oil, chemical, petroleum and other liquid forms. Our services also enable us to provide any customized forms of these flanges products. The square flanges are made accordance with JIS B2291/JIS F7806 standards which are used between the pipes to pipes components connections. These are mostly used in hydraulic systems where the passages of fluids are made of two different kinds of materials which are pure steel and stainless steel. These are also commonly used and designed for square flanges, SHAB Square Flanges and SSAB Square Flanges. The pressure rates for square flange are available in 210 kg/cm², 280 kg/cm², and 350 kg/cm². It is with a single available socket weld connection that requires the pipe to have plain ends for excellent pipe solution.

Square Flanges Key Features:
- Can be attached to the pipe without welding (sometimes an additional seal weld is used as well)
- Ideal for higher pressure and temperature applications for small pipe sizes
- Not recommended for larger loads, especially when subjected to higher torque
NOTE: This flange is referred to as either threaded or screwed. It is used to connect other threaded components in low pressure, non-critical applications. No welding is required.

ANSI B16.5 Square Flanges Dimensions & Weight Chart:
There are three types of Square Flanges under this standard:
- SHAB – Used with hexagon hex bolts, larger flange body size (Figure 1)
- SSAB – Used with socket cap screw, smaller flange body size than SHAB (Figure2)
- LSA – Oring side only, L shaped internal flow (Figure 3)
