Stainless Steel Flanges

We offer wide range of stainless steel flanges like weld-neck, slip-on, socket weld; lap- screwed type joint, blind and screwed type. These conform to ASME B16.5, ASME B16.47, ASMEB16.48, BS EN 1092, BS 4504, API-605, API-590, MSSSP44, DIN 2632 to 2638, DIN 2576, 2642, 2527 and 2566 standards. Procured from reliable vendors, these flanges cover full range of pressure ratings these specifications (150 - 2500 psi for ASME & PN6-PN400 for DIN / EN flanges). Non Standard flanges are made upto a diameter of 4000 mm and the weight not exceeding 5,000 Kg.

Features:

• Corrosion resistance
• Dimensional accuracy
• Chemical resistance
• High strength
• Durability
• Fine finish

Types of Flanges

• Weld Neck Flanges

Application: Weld neck flanges are mainly used on heat coupling of pipes when there is possibility of expansion of the section while bending stress on the coupling.

• Slip on Flanges

Application: These are used in quick assembly to save the cost; these are also used in less strict requirements in terms of length of pipe section.

• Socket Welding Flanges

Application: Socket welding flanges are recommended for orifice flanges. These work as substitute for slip-on flanges in the cases where the diameter of the tube is very small and working pressure is very high.

• Lap joint Flanges

Application: The lap joint flanges are primarily used when quick assembly and disassembly of pipeline section is required under limited working pressure.

• Threaded Flanges

Application: These flanges are used in special requirements to work under high temperature and pressure, making sure no welding joint is made at the assembly.
