Specially Designed Vertical Constants

Specially Designed Vertical Constants

Specially Designed Vertical Constants

The vertical constant is used when piping stress is critical and pipe is subject to vertical movement in excess of ½ inch due to thermal expansion, and also at locations here it is necessary to avid any transfer of stress from support or onto critical terminals or connecting equipment. These constants are manufactured by Piping Technology & Products, Inc.

Insulated Pipe Shoes for Hot Applications

Insulated Pipe Shoes for Hot Applications

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.

Sway Struts for a 250 MW Power Plant

The picture seen above is a mechanical snubber attached to a rod with a pipe clamp. Below the snubber is a rigid sway strut for 36” pipe and four smaller sway struts. The snubber will dampen sudden shocks and vibrations in the piping system. These show the variety of built by Piping Technology & Products, Inc. for a 250 megawatt power plant.

Color-Coded Insulating Components

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.
