Customer requirements for customization
Pro-hydrogen, near-sulfur. Pressure vessels, heat exchangers, hoods, etc.
In industrial production, the leakage occurring during the fluid transportation process causes a great deal of losses and even damages, laying a hidden danger for safety production.
■ Flange preload force loss factors: elastic interaction, temperature change, pressure fluctuation, mechanical vibration
■ Preload loss factors of valve: Temperature change, pressure fluctuation, aging of packing, mechanical vibration
■ Preload is too large
■ Excessive strength of flange fasteners: Causes excessive pressure and exceeds the strength limit of gasket material
■ Valve packing pre-tightening force: Causes pressure to exceed the elastic limit of the packing or cause the valve to lock
■ Application of WDF901H in flange cover of heat exchanger
Case: Reforming the heat exchanger, temperature 500 degrees Celsius, pressure 19 Bar, medium: gasoline, H2
■ Application of WDF901N on the furnace flange
Case: Acting Inlet Flange Temperature 580°C - 650°C, Pressure: 2.5 Bar, Medium: Flue Gas Mixture
