Cold Shoes to be Shipped to Puerto Rico

Cold Shoes to be Shipped to Puerto Rico

Cold Shoes to be Shipped to Puerto Rico

Normal pipeline insulation is not designed to support the pipe or its contents. When insulated pipes are supported, the weight of the pipe, the contents, the operating temperature, and the amount of energy loss must be considered.  In order to support the pipe and minimize energy loss from heat transfer, a pre-insulated pipe support is necessary.   If the material in the pipe is high temperature such as high pressure steam or heating oil, then high temperature insulation is required, and these supports are called hot shoes.  If the material is cold, such as liquefied natural gas, cooling water or ammonia, then low temperature insulation is needed, and these types of supports are called cold shoes.

PT&P received the order to fabricate 140 cold shoes from a contractor in Puerto Rico. The overall weight of the order was 11,000 lbs and was produced in 8 weeks. The shoes were designed to support 8, 10 and 12 inch pipe sizes with 2 inches of insulation. They were designed using our Pipe Shields Division and correspond to the following model numbers: B2000, B4000,and C4100. These can be seen on our Pipe Shields website or you can request a catalog.

Cold Shoes Being Assembled

These pre-insulated pipe supports were manufactured for a Houston based engineering and construction company to complete an on-going project in South Africa. The polyurethane foam insulation is wrapped with a vapor barrier to prevent moisture, and the ends are coated with a monolar mastic paint to seal the pores. The carbon steel fabrication that surrounds the insulation has an elaborate three-coat paint system to help protect the steel from corrosion. This design allows for an integral combination of insulation and structural support in one pipe support assembly. It also minimizes labor in the field in regards to the installation of insulation.

Pre-Insulated Cryogenic Supports with PTFE, 25% Glass Filled, Slide Plates

Measuring Overall Length of the Support

Fifty Pre-Insulated Cryogenic Supports with PTFE, 25% Glass Filled, Slide Plates were manufactured for a 36” stainless steel piping system. The steel portion of the Cryogenic Supports is fabricated from ASTMA 240 Grade 304L stainless steel. The insulation used for the Slide Plate is Micarta, capable of supporting temperatures as low as -300°F. Each Pre-Insulated Cryogenic Support is 72” in length and weighs 2,000 lbs. It is designed to support the pipeline and accommodate 45” of axial travel at each support. They are used as Cryogenic Pipe Supports for a piping system that crosses a 1,000 foot suspension bridge.

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.

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.
