Reverse Acting Buckling Pin Bursting Disc   BT-KUB / BT-KUB-F   This unique reverse acting bursting disc incorporating laser cut buckling pin design features represents the most rugged and versatile bursting disc available in today’s technically driven market.   The buckling pin cut profiles work according to formula calculated by Leonard Euler and enable the lowest possible tolerances.   The BT-KUB can be used in any gas, vapour or liquid media under the harshest of conditions due to its standard operating ratio of 98%, the tightest operating ratio available in the burst disc  industry.   The two layer material design and range of materials of construction offer the greatest flexibility in cost savings while maintaining total corrosion resistance. The disc design comprises of an upstream sealing membrane with a smooth unblemished profile ie; no scorelines, dimples or indentations. This makes the BT-KUB the ideal disc for aseptic and sanitary applications due to their being no available dead space for bacteria or product accumulation.The material selection of the sealing membrane should be specified according to the requirements of the process (possibly corrosive) where the disc is being applied.   Due to the reverse acting compression mode of the disc it is also totally immune to backpressures and vacuum and is ideally suited where CIP/SIP scenarios are used.   Downstream the burst element with its the buckling pin technology is totally isolated from the process and can be confidently specified in standard SST irrespective of any aggressive process media; dependent upon no corrosive vapours being present downstream.   The BT-KUB is totally torque independent when mounted in the IG-KUB Disc Holder. Its response pressure performance (burst rating) is not influenced by the  torque applied. For pressures below 1.0 barg, the BT-KUB can be installed directly between flanges.

Your benefits:

	Easy handling due to outstanding robust design
	Fully torque independent installation
	Extraordinary service life

  BT-KUB-V-Series

   

  With the unique and innovative generation of bursting disc BT-KUB-V-Series for the first time it is possible to perform the Partial Stroke Test (PST) on pressure relief valves (PRV) whilst in plant operation conditions, i.e. “in-situ”. Expensive loss of production due to downtime and costly dismantling/ mounting times are reduced to a minimum. Optimum plant production is maintained.

   

  The concept of the BT-KUBV- Series is both ingenious and convincing: The bursting disc is installed upstream of the pressure relief valve. Apart from the absolute sealing tightness of the process line, the pressure relief valve is now also protected against the effects of corrosion and contamination. On site the pressure relief valve can be lift tested for any possible leakage. The unique back pressure resistance of the BT-KUB-V-Series is achieved by modifying the proven, double-layer KUB design.

   

  The performance characteristics and the flow rate of the pressure relief valve are not influenced by the upstream BT-KUBV- Series bursting disc. Conventional single layer scored bursting discs cannot meet these requirements.

  
  

  Your benefits:

  	Extended lifetime of PRV
  	Enabling selection of standard materials of construction for the PRV
  	Extended maintenance intervals for PRV resulting in massive cost savings

  BT-KUB-G-Series

   

  Providing a unique option, the BT-KUB-G-Series reverse acting disc is the world’s first ever bursting disc manufactured for the challenging demands of geothermal power plant applications, as the endurance of a bursting disc is defined by the extreme temperature and constant corrosion requirements.

   

  Special finishing technology is used to withstand these aggressive effects providing more than double the lifetime of the disc when compared with more conventional “scored” bursting discs.

   

  Needless to say this provides considerable operational cost savings.

  
  

  
  

  Your benefits:

  	Cost-saving operation
  	Easy and quick installation
  	without special tools
  	High operational safety
