Product Description

Product Description

 

SM Graphite type bursting disc device

It is a bursting disc device which takes graphite material as the base.

Product Parameters

 

If no pressure fluctuation, operating pressure ratio 80%. If there is pressure fluctuation, operating pressure ratio 60%.
There are fragments after bursting. It cannot be used with safety valves in series connection.
It is of fully opened design.
Applicable temperature: -50ºC~200ºC.
It can be lined with PTFE or FEP.
It can be either separately installed between the flanges or used coordinately with clamper.
Applicable to various mediums of stronger corrosion.

Burst Disc Pressure Specifications (MPa)

Pressure Range	0.01-3.0MPa
Pressure Tolerance	For burst pressure <0.05 MPa: ±25%
	For burst pressure 0.05-0.3 MPa: ±15%
	For burst pressure 0.3-3.0 MPa: ±10%

Highest Applicable Temperature of Bursting Disc Materials:

Bursting Disc Material	Highest Applicable Temperature  ( ºC )
Aluminum	100
Copper	200
Nickel	400
Austenitic stainless steel	400
Copper-nickel alloy(Monel)	430
Hastelloy	480

Graphite	200
Note: When the surface of the bursting disc is coated with sealing lining or protection lining, the influence from the coating material to the applicable temperature shall be accounted.

 

Note:The technological parameters of the protected equipment are the basis for selection of rupture disosafety device models. Whether the parameters are accurate is directly related to the effect of product modelselection, the realization extent of product technical characteristics and the service cycle.

Application

Chemical & Petrochemical Industry
* Reactor/Pressure Vessel Protection: Prevents overpressure explosions caused by uncontrolled chemical reactions or abnormal temperature rises.
* Pipeline Systems: Isolates different pressure sections to avoid pressure fluctuation propagation.
* Storage Tank Relief: Protects liquefied gas or toxic substance tanks from overpressure risks.
Energy & Power
* Boiler Systems: Acts as a supplement to safety valves, rapidly releasing steam pressure.
* Gas Turbines/Nuclear Plants: Prevents pressure surges caused by cooling system failures
Pharmaceutical & Food Industry
* Sterile Production Lines: Provides leak-tight protection for sterilization tanks or fermentation vessels to avoid contamination risks.
Aerospace
* Fuel Tanks: Releases pressure under extreme temperature or pressure variations to ensure flight safety. Environmental Protection & Fire Safety
* Dust Explosion Protection: Used for explosion relief in dust collectors, cyclone separators, etc.
* Firefighting Systems: Suppresses shockwaves from combustible gas explosions.
 

Our Advantages

Our company is a science & technology-oriented enterprise specializing in rupture disk safety devices, rooted in Chinese aerospace engineering technology. The development of our first rupture disk for aerospace applications began in 1959. In 1981, this specialized technology was successfully adapted for civilian use, resolving long-standing domestic production challenges of industrial safety devices across multiple sectors in China. In 1986, the company obtained the Manufacturing License for Rupture Disk Devices issued by the Ministry of Labor. In 2000, it was certified as a high-tech enterprise by the Science & Technology Department of Liaoning Province.
