CONVENTIONAL SIMPLE DOMED RUPTURE DISK ( LP TYPE)

The burst pressure of Conventional Simple Domed Rupture Disk is determined by the tensile strength of the material employed. System pressure is subjected to the concave side of rupture disk on normal operating condition. When excessive pressure occurs in the protected system, the dome begins to thin out and the disk bursts, providing a full relief opening.

Types

◆ Simple Rupture Disk (LP): withstand backpressure, non-backpressure or vacuum conditions with disk holders.

◆ Integrated Rupture Disk (LPZ): suitable for super-high pressure conditions.

◆ Welded Rupture Disk (LPH): suitable for high and super-high pressure conditions.

◆ Rupture Disk with Vacuum Support (LPT): suitable for vacuum or backpressure conditions.

  

Features 

◆ Broad range of application, and can choose the corresponding assembly according to different burst pressure and vent area. 

◆ Manufacturing ranges depend much on material strength. 

◆ Designed for gas, liquid service

◆ High temperature and pressure.

◆ Maximum operating pressure equal to or less than 70% of the minimum burst pressure, and not suitable for pressure pulsating conditions.

◆ Fragments on burst.

◆ Short service life and easily cause creep deformation and fatigue damage

◆ Obvious temperature effect may cause burst pressure fluctuation. The temperature goes up while burst pressure declines.
