Hot Shoes for a Chemical Plant in Texas
Piping Technology & Products, Inc. designed and manufactured 60 Marinite® hot shoes for a chemical plant in Texas.
These hot shoes are composed of Marinite®(high-density calcium silicate) and carbon steel. They were made for 8 NPS with 7 insulation. These shoes are used on steam lines, effluent lines, and any other process lines where it’s imperative that thermal energy is not lost through the pipe support. Tests were performed to show outer skin temperature at operating conditions.

Insulated Pipe Shoes for Hot Applications
Piping Technology & Products, Inc. supplied both “hot shoes” for high temperature lines and “cold shoes” for cryogenic lines in this new plant. The shoes sit on the steel beams of the pipe rack and support the insulated pipe. The bottom photograph shows several of the shoes prior to shipment. The two large cold shoes in the foreground are lined with PUF (polyurethane foam) which functions both as an insulator and as a load bearing member at temperatures as low as –300oF. Hot shoes are lined with calcium silicate or Marinite which can function up to 1200oF.

Pipe Shoes for Hot Temperature Applications
Pipe Shoes for Hot Temperature Applications
The pictures above show insulated pipe supports designed for two very different temperature applications. The top picture shows an inspector checking “hot” shoes for high temperature piping. They have one 180 degree section of the insulation made of foam glass and the other 180 degree made from calcium silicate. Some components are chosen for their insulating properties only, other must both insulate and support the load of the pipe. The bottom picture shows a 54 inch “cold” shoe of galvanized steel with PTFE slide plates on the bottom. Inside the galvanized steel is bonded a layer of polyurethane foam which has been coated with a white vapor barrier. This polyurethane layer provides both insulation and support of the load at cryogenic temperatures.
