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.
Piping Technology & Products, Inc. designed and fabricated these saddle supports to support FRP pipe or similar plastics in sizes from 2″ to 36″ in diameter. The saddle support is fabricated from a molded density 20 polyurethane block with a load bearing capacity of 150 PSI that allows for high loads for a 36″ diameter line.
The base is bonded to a 20 gauge steel pan that provides a steel to steel resting surface. The foam is extended on each side of the base to allow field strapping of the support to the pipe. These saddle supports are often used in a circulating water service. These particular supports are to be used in a power generating station in the U.S.
Piping Technology & Products, Inc. designed and manufactured eight polyurethane pipe rollers for a gas plant in California. These 24 non-conductive pipe rollers are fabricated from polyurethane. They were pre-tested for an operation load of 6,100 lbs. The purpose of these polyurethane pipe rollers is to support gas piping where a non-conductive support is required.
The two pictures above show two types of polyurethane products produced by Piping Technology & Products, Inc. for piping systems. At the top are cold shoes to support piping at cryogenic temperatures. The polyurethane cradle is bonded to steel shield which is welded to a T-bar. These cradles are produced by pumping the chemical components required into a mold which gives them the correct shape. At the bottom are supports produced by drilling and machining solid polyurethane blocks. Polyurethane provides both insulation and the strength to support pipes at cold temperatures.
In the picture above, a test of the bonding strength of an adhesive designed for low temperature applications is being conducted. Polyurethane strips have been bonded to metal strips which are pulled apart in a load cell which measures the force applied.
Polyurethane is often specified for components of insulated pipe shoes and supports for cold temperature applications. Polyurethane provides both insulation and load carrying capacity for pipes when it is bonded to a metal pipe shoe or support. Piping Technology & Products, Inc. fabricates all types of insulated pipe supports. The type of insulation specified depends on the temperature profile the pipe will experience and the loads and movement at the point of application.
