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.

Custom Designed Vertical Upthrust Constant

Custom Designed Vertical Upthrust Constant

Pictured is a vertical upthrust constant developed for an application where the traditional horizontal upthrust would not fit.

Our Canadian customer searched to find existing products to support a pressure vessel which was to be located in an area with no additional horizontal space. PT&P developed this design and tested a prototype within one month to meet customer’s schedule.

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.

Four “Ball Type” Flexible Strut Joints

Four “Ball Type” Flexible Strut Joints

Pictured above are four “ball type” flexible strut joints often used to help control vibration. These struts are attached to piping or other equipment to restrain movement in one direction while allowing movement in another direction. Movement may be due to temperature or pressure changes. Piping Technology & Products can furnish strut joints made from various materials and with various finishes depending on the load requirements and the environment where they will be installed.
