Standard Flanges (Weld-neck, Slip-on, Socket-weld, Lap-joint, Blind and Screwed Types) are manufactured by Gold Tech Forge to specifications of ASME B16.5, ASME B16.47, ASME B16.48, BS EN 1092, BS 4504, API-605, API-590, MSSSP44, DIN 2632 to 2638, DIN 2576, 2642, 2527, 2566. Flanges cover full range of pressure ratings of these specifications (150 – 2500 psi for ASME & PN6-PN400 for DIN / EN flanges). .
Rolled & Forged Flanges

Gold Tech Forge manufactures various type of carbon steel, alloy steel, stainless steel and duplex steel as per customer recognized material standard (ASME/ANSI/DIN). The flanges are also manufactured as per customer specific requirement/ drawings.
Weld Neck Flanges
Application: These are mainly used on heat coupling of pipes in the most difficult cases, i.e., when bending stress on the coupling, due to expansion of section or to other forces, is foreseen.
Slip on Flanges
Application: Used in quick assembly to save the cost, these are also used in less strict requirements in terms of length of pipe section.
Socket Weld Flanges
Application: 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: These 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.
