Insulation for pipes or vessels with low temperature material, usually below freezing.
Check out our most recent article that looks at the history of insulated pipe supports through the past 100 years. Learn about the developments made in the 1950’s and 1960’s that introduced the use of “Foam Glass”, a lightweight material that is manufactured primarily from recycled glass and used in the design of insulated pipe supports. Later, polyurethane was developed to provide greater load carrying capabilities. Read the full article on the:
PT&P manufactured 72″ dia. insulated supports for temperatures as low as -260°F. The insulation is multi-layered comprised of polyurethane foam with a density of 20 PCF, a vapor barrier, an aluminum metal jacket, and acoustic pads. The acoustic pads are installed around the cold shoe to absorb vibration. The base and bearing plates are fabricated from carbon steel. The shoes will be used to support and insulate piping in a receiving & regassification plant and refinery.
The operating temperature for these cryogenic shoes ranges from -290°F to 90°F. They are designed for 56″ diameter pipe and are capable of supporting loads up to 40,000 lb. The insulation is multi-layered comprised of 20 PCF polyurethane, a vapor barrier, an aluminum metal jacket, and acoustic pads. The acoustic pads are installed around the cold shoe to absorb vibration. The base and bearing plates are fabricated from carbon steel.
The hot shoes are fabricated from A-36 carbon steel with 304 stainless steel slide plates. The 18″ dia. hot shoe has a maximum vertical load of 5500 lb. and the 24″ dia. hot shoe is capable of loads up to 13,750 lb. All the supports in this project are designed for temperatures of up to 1200°F. In addition to the insulation, these supports are capable of sliding axially or laterally as part of the piping system.
