One of the prime responsibilities of the process plant is safety. An important aspect of this responsibility is the protection of equipment against failure from overpressure. Apart from all the process control applicable to avoid this overpressure, the final safety element is Pressure relieving device.  

  • Pressure relieving device considered for this course is Safety or Pressure relief valve. Participants will enjoy a through learning of Pressure relief valve right from its Operational basics, design, installation, malfunction, Inspection and Testing, Stamping and VR accreditation procedures.
  • The course will cover ASME Sec I and VIII related to Safety relief valve, API 520 part 1 and 2 followed by API 521, 526 and 576.
  • Requirements and guidelines for the VR accreditation program and become acquainted with the National Board Inspection Code and ASME PTC 25.
  • All above information will be well presented and discuss with animations and actual videos.
