A pressure relief device (PRD) protects a pressurized container from rupture due to over pressurization – preventing a catastrophic event that can harm people and damage equipment. Regardless of your background (extensive to some or no experience with PRDs) this webinar will help you advance your knowledge of this important topic.
CGA Technical Manager Jerry Sameth will kick off the webinar with a look back at the genesis of pressure relief devices from 1680 to 1913 when the Compressed Gas Association was founded. He’ll also review the current landscape for pressure relief devices – exploring their applications for industrial, medical, and specialty gases.
Next, John Piscitelli with Sherwood Valve will discuss pressure relief devices on compressed gas cylinders. He’ll review incoming inspection and testing of various PRDs specified in CGA S-1.1, Pressure Relief Device Standards-Part 1-Cylinders for Compressed Gases (CG1, 2, 3, 4, 5, and 7) including disks, fuse metal and springs, along with assembly and process testing of finished assemblies to ensure leak tightness, burst pressure, as well as start to discharge on CG7s.
Tom Drube with Chart Industries will then provide an overview of pressure relief devices on portable and stationary tanks. He’ll examine vital information from CGA S-1.2, Pressure Relief Device Standards-Part 2-Portable Containers for Compressed Gases and CGA S-1.3, Pressure Relief Device Standards-Part 3-Stationary Storage Containers for Compressed Gases, including the basis for relief device sizing, comparison with other codes, the significance of Gi, Gu, A^0.82, the reference temperatures of 1200F and 590F, as well as a discussion of valve chatter.
John Eihusen with Hexagon Composites will follow with a discussion of pressure relief devices on composite overwrapped pressure vessels (COPVs), including configuration and operational differences from other types of PRDs. He’ll also explore applications in large tubes and vehicle applications including hydrogen, compressed natural gas (CNG), helium, and marine operations.
Jerry Sameth will close the presentations with an exploration of CGA’s ongoing commitment to pressure relief devices – including incorporation by reference (IBR), testing conducted, ongoing interactions with U.S. Department of Transportation (DOT), ISO, and the UN/ECOSOC Sub-Committee of Experts on the Transport of Dangerous Goods (UNSCETDG).
A lively panel discussion will follow.
- Non-technical, entry-level (little to no knowledge of the topic is required)
- Intermediate (basic knowledge and understanding of the topic)
- Advanced (extensive knowledge and experience with pressure relief devices)
The two-hour webinar will have opportunities for Q&A with the audience, so come prepared with your questions.
