SPECIFICATION

Forged & Plate Flange	Blind flange, Lapped Flange, Threaded Flange, Slipon Flanges, Weld Neck Flanges, Socket Weld Flanges.
Flange Material Wise	Titanium flanges, tantalum flanges, nickel flanges, cupro-nickel flanges, zirconium flanges, hastelloy flanges, incolloy flanges, niobium flanges, hr alloy flanges, alloy 20 flanges, monel flanges, inconel flanges, nimonics flanges, stainless steel flanges, duplex steel flanges, super duplex flanges.
Blind Flanges	Specifications : ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range) Applications : Used in quick assembly to save the cost, these are also used in less strict requirements in terms of length of pipe section.
Slip on Flanges	Specifications : ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range) Applications : 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	Specifications : ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range) Applications : 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	Specifications : ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range) Applications : These are primarily used when quick assembly and disassembly of pipe line section is required under limited working pressure.
Threaded Flanges	Specifications : ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range) Applications : These flanges are used in special requirements to work under high temperature and pressure, making sure no welding joint is made at the assembly.
Weld Neck Flanges	Specifications : ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range) Applications : These are mainly used on heat coupling of pipes when there is possibility of expansion of the section while bending stress on the coupling.
