What is a pipe guide?

February 11, 2011

A pipe guide can be categorized into two types. The first is as a shoesupport attached directly to the pipe with external components which direct thepipe during the thermal deflection cycle. The second type of guide surroundsthe pipe and is attached to stationary structures, allowing the pipe to move.

What is a cold shoe?

A cold shoe refers to a support component which incorporates an insulating material that attaches directly to the pipe and also functions as a load bearing component transferring the load to a point outside of the insulating enclosure.

How does one mount a pipe to the floor?

February 10, 2011

There are numerous ways to mount a pipe to the floor including using u-bolts, hold-down pipe clamps, or pipe shoes. The most applicable of these options depends upon the use of the support whether it be as a load carrying member, guide or anchor.

Why use pipe shoes on un-insulated lines?

November 2, 2010

You can utilize pipe shoes on un-insulated lines simply to support the pipe or transfer the pipe load to other support components.

New Patent for a High Temperature Support for Insulated Pipes
PT&P has developed a high capacity support for insulated pipes which does not rely on the insulation to carry any of the load. The design has several advantages over previous designs:

  • Since the insulation does not carry any mechanical load, it can be chosen solely on the basis of its thermal properties. In particular, cyclic loading, which has caused insulation failure, is not a problem.
  • The support provides effective restraint for all six possible components of loads, X, Y, Z-Rotational and Translational. In particular, axial and torsional loads are readily accommodated. These represent difficulties for supports which rely on the insulation.
  • It is easily installed in the field. It is attached to the pipe with a standard bolted pipe clamp. Thus there is no field welding.

The support consists of a shoe, similar to the PT&P Fig. 4500 Insulated Shoe Support for Hot Pipe (Hot Shoe) and two clamps, similar to the PT&P Fig. 50 Light Two Bolt Pipe Clamp. Each clamp is attached to the shoe by a steel plate which is designed to carry the design load, and is shape optimized to minimize heat flow from the pipe.
