SERRATED GASKET (GROOVED GASKET)
Grooved(serrated) metal gasket is also made of cold rolled metal plate, but it has concentric grooves and effective sealing is minimized so as to increase sealing effect. both of these gaskets are extensively used on pipe flanges, valve bonnets, pressure vessel, Heat exchanger at high pressure and temperature
METAL DOUBLE JACKETED GASKET
DONGSUH metal jacketed gaskets are fabricated with Non-Metallic for inner filler as metallic of outer shell. They are widely used in heat exchangers, Boilers, pumps, valves with high pressure, high temperature and severe corrosion conditions for various plants. (Powers, Chemicals, Oil Refineries, Iron Plants) Metal jacketed gaskets fabricate by hand-made to various shapes and sizes as Round, Oval, oblong in order to supplying. Besides, many meterials are able to use according to temperature, pressure and corrosive conditions. Recently for sealing improvment Graphite and PTFE tape glued together on both sides of gasket in view of increasing consumption. Effective is especially high in case of demage caused by corrosion on flange surface
PRESSURE SEAL RING
There are self sealing gaskets employed in high pressure and high temperature valve covers. The gasket receives is initial sealig stress by tightening the bolt, and is then expanded radially by the end force of the fluid to produce the reguired sealing pressure
RING JOINT GASKET
Ring joint gasket is a type of pressure energized gasket used on pipe flanges, pressure vessels, Valve bonnets handling, high pressure steam, gas, hot oil, solvent vapor at high temperature. DONGSUH’s experienced technology offers many different types so that customers may select the most suitable one in accordance with operating conditions.
