Product Description

Product Description

 

LC-Domed grooved type bursting disc

On the domed casing of the bursting disc, a "+"or annular groove is machined. When over pressure occurs to the protected system,
the bursting disc shall break along the groove to discharge the pressure.

Product Parameters

 

Applicable to gas and liquid mediums.
Operating pressure ratio70-80%
After bursting, there are no fragments and it can be used with safety valve in series connection.

 

LJA clamping holder is used with LC rupture disc.

 LCI can process pressure range: minimum/maximum burst pressure 22ºC Unit: MPa

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.
