China LF Bursting Disc:
LF Bursting Disc is the conventional domed seamed bursting disc.
Structure features:
This type of bursting disc shall have one or more layers at least one of which shall have slits or slots so as to reduce its strength and to control the bursting pressure.
Technical features:
1. Applied to gas, liquid medium and the operating conditions of low bursting pressure;
2.When the coincident temperature is determined, the applicable temperature of sealing film shall be taken into account;
3.Maximum operating pressure can reach 80% of the bursting pressure;
4.Fragments may arise in bursting, so the serial usage with the safety relief valve is not recommended.
5.LF bursting disc with large diameter may gain extremely low bursting pressure, applicable in dust pressure-relief and explosion-suppression occasions;
6.Code of Products without support is LF, and the code of products with support is LFT.
