The matters to be noticed in the model selection of bursting disc:
1, the use of blasting sheet material temperature
2, working medium on the corrosion of materials, the general can do anti-corrosion treatment spraying fluorine plastic layer or increase the protection layer of fluorine plastic as anticorrosive protective film
3, the bursting disc and the safety valve should be selected in series, the release pressure of the bursting disc does not produce fragments of the model.
The bursting disc and the safety valve is generally used in combination with more stringent requirements under the conditions of single use safety valve safety, such as toxic and flammable and explosive, blasting and safety valve used in combination can achieve the sealing of the blasting action after the safety valve can play a role in temporary work.
Bursting disc and the holder is installed in the middle of the flange, the flange and the clamping device between the gasket can play a sealing role, usually copper or PTFE cushions, bursting disc and the holder is not allowed to add any gasket between. The gripper and the bursting disc as a supporting device, usually more than 1 kilograms in pressure vessel equipped with blasting as a pressure relief device are needed to clamp, clamp the general material of carbon steel and stainless steel, such as corrosion can be selected for PTFE holder at the inlet, outlet for carbon steel or stainless steel the holder at the temperature above 260 DEG C, the holder may consider other conditions suitable for use of materials.
Working condition of bursting disc:
1, pressure vessels due to a sharp increase in the reaction pressure, the safety valve at this time is too late to open, the high sensitivity of bursting disc can meet the requirements of pressure vessel.
2, the pressure vessel is easy to crystallize the crystal has a certain viscosity, easy to plug the use of safety valves, to pressure relief requirements, at this time should use the bursting disc as a pressure relief device.
3, medium pressure vessel is toxic and flammable and explosive medium and high corrosion resistance, the selection of safety valve high cost, and the valve core material has certain requirements, the sealing performance may not be able to meet the requirements, you should choose blasting.
