Product Description

Product Description

 

LP Domed ordinary type bursting disc

The bursting pressure of the bursting disc is controlled by the tensile strength of the bursting disc material. The system
pressure acts on the concave surface of the domed casing of the bursting disc. When overpressure occurs to the protected system,
the bursting disc shall be tensioned and the domed casing wall will be thinner until breakage. In this way, the pressure shall be discharged.

Product Parameters

Applicable to gas and liquid mediums.
Applicable to environment of high pressure and high temperature.
Operating pressure ratio70%
After bursting, there are fragments, and don't use it with safety valve in series connection.
It is provided with support and can bear back pressure.
The pressure is more greatly affected by the tensile strength of the material.

LJA, LJB and LJC clamping holders are used with LP rupture disc.

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.
