Snubber Extension Rod Ends

The hydraulic snubber extension rod ends(seen above) were manufactured from carbon steel. Ranging in sizes 1 , 4, 5, and 6, the weight of each increase with size, therefore; the weight of each unit varies. Extension rod ends are used in conjunction with hydraulic snubbers to extend the overall length of an existing snubber. They are applied to piping systems when unrestrained thermal movement must be allowed but must also be restrained during impulsive or cyclic disturbance. The turn around time for these units was 3 weeks.

3 Wedge Action Mechanical Joints for a Suspension Bridge

Three wedge action mechanical joint restraints made of ductile iron materials were utilized to assist in the construction of a suspension bridge. Also, these mechanical joints provide for vertical and axial restraint for the bridge. Each weighs approximately 300 lb. and measures 24” long by 16” wide, and 12” tall for a 6”, 10”, and 12” ductile iron pipe. They are capable of supporting 50,000 lb. In addition, they are designed for seismic conditions with the ability for 7” of axial travel.

Single Cold Shoe

These cold shoes are made of polyurethane for cryogenic pipe lines at a liquid nitrogen gas plant. They measure between 8” to 16” in diameter, 30” long with 4” of insulation. These cold shoes provide insulation in the support area where the regular pipe insulation (foam glass) is not sufficient to support the load.

Alternate View of Sway Struts

Sway struts are used to restrain movement of piping in one direction while providing for movement due to thermal expansion or contraction in another direction. These sway struts are made of ASTM A387 GR22 weighing at 1,485 lbs each. They are 6″ in diameter and 8’2″ long and are used for main steam valve supports with specifically designed spacers, pins, and retainers capable of restraining movement up to 90,000 lbs at high temperatures exceeding 750F. The turnaround time for this was 6 weeks.

Side View of the Cold Shoe

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.

Side View of Pre-Insulated Anchor

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.
