Color-Coded Insulating Components

Color-Coded Insulating Components

The pictures above show pipe supports designed for a system with very cold operating temperatures. The insulating components are polyurethane, which are inside the galvanized steel exterior of the support. At the top left of the picture are the color-coded polyurethane components of a “cold shoe” for a 60” pipe, the top (green) is 14 lb/ft3 density and the bottom (orange) is 20 lb/ft3 density. The higher density material has greater compressive strength but it is a better conductor of heat. The other pictures show finished shoes which have white coating over the polyurethane. Hot shoes, designed for high operating temperatures, are similar but usually have different insulating materials.

Bonding Strength Testing for Low Temperature Application Adhesive

Bonding Strength Testing for Low Temperature Application Adhesive

Bonding Strength Testing for Low Temperature Application Adhesive

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.
