Weld Neck Flanges
Application: Used for high-stress conditions, especially where bending stresses may occur due to thermal expansion or external forces.
Slip-On Flanges
Application: Ideal for quick assembly and cost-effective installations where tight length tolerances are not critical.
Socket Weld Flanges
Application: Recommended for orifice installations and suitable where the pipe diameter is small and the working pressure is high.
Lap Joint Flanges
Application: Used where frequent assembly and disassembly is required, typically under low to moderate pressure.
Threaded Flanges
Application: Suitable for environments involving high temperature and pressure, especially where welding is not feasible or allowed.
Spade/Spacer & Spectacle Blinds
Application : Forged Spectacle Blinds & Spades/Spacers are used in piping systems to isolate a pipeline during maintenance, inspection, or testing. The spade blocks the flow completely, while the spacer allows normal flow. They are commonly used in oil & gas, petrochemical, and power plants for safe shutdown and maintenance of equipment.
As one of India’s leading flange manufacturers, CHW Forge is committed to delivering reliable, high-quality products tailored to your industry requirements.
