Roller stands are used to support pipelines that expand and contract longitudinally in the axial direction and where vertical adjustment is not necessary. These roller stands are made of stainless steel and designed for a 26″ pipe. They weigh 160 lbs and are capable of supporting 7,500 lbs. Load testing at 1,000F was completed for performance assurance.

Constant support hangers are used to support pipes subjected to vertical movement. The (Fig. PTP 200) constants are designed to support loads from 4,000 lbs to 57,000 lbs. Each weighs approximately 1,500 lbs to 2500 lbs and has a travel of up to 4″ with an adjustable travel stop. Their sizes range from 15 to 100.
The advantage of an adjustable travel stop is that the constant is able to “lock in” at any position within the range of travel for a given constant. This alleviates the need for a total “shut down” of the piping system for temporary conditions such as hydrotesting, repair, or replacement.

These cold shoes are made of polyurethane with an 8″ thick insulation to fit a 30″ pipe. The shoes are capable of insulating and supporting at temperatures as low as -360F. This allows for the LNG to be transported through the pipe at extremely low temperatures. These cold shoes were rushed to our client during a “turnaround” to replace the original supports that had failed.

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.
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.
