Cylinder Pipe Guides for a Power Plant

Cylinder Pipe Guides on Shipping Floor

Piping Technology and Products, Inc. designed and fabricated cylinder pipe guides (aka spider guides) for pipes ranging from 1” to 20” in diameter with 1” to 4” of insulation.

Cylinder Pipe Guides

These guides are designed to control lateral pipe movement and maintain the alignment of the piping through its axial and contraction cycles. A single piping run uses multiple spider guides to avoid a fulcrum or an imposed lateral deflection on critical components.

Components of these guides include carbon steel plates, stock clamps, angles and hot-dipped galvanized pipes. The outer shields have diameters ranging from 6″ to 29-1/2″. The maximum design temperature for the spider guides is 750°F.

In addition to spider guides, over 40,000 lbs. of material were supplied for this project including variable springs, constants, and miscellaneous structural items.

These cold shoes are used for anchoring pipelines against movement caused by thermal expansion and by fluid flow in the pipe. The total weight of the 10 cold shoes is 8,336 lbs. They have 4 1/2″ of insulation and are made to fit a 12″ pipe. Their length varies between 18″ to 24″ for 6″ to 12″ of axial movement. The cold shoe is made of polyurethane insulation and A36 carbon steel. They are drop-in-place anchors that only need to be welded into the pipe run and fastened to the pipe rack. They were manufactured to specific design loads and movements for an LNG plant in Georgia.

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:

Pipe Shoe

Pipe Shoe

  • 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.
