Cryogenic Trunnions with Permali Blocks Designed for Ethylene Loss Recovery Lines
May 20th, 2013
Comments off
PT&P designed cryogenic trunnion supports for ethylene loss recovery lines at a plant in Texas. The trunnions were fabricated from 2″ dia. stainless steel pipes and have a maximum height of 3′. They include 6″ x 6″ permali blocks measuring 2″ thick each. The permali block isolator is a laminated phenolic material from layers of wood impregnated under vacuum and heat with synthetic resin. The temperature range for these supports is from ambient to -300°F.
