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.

Positive Anchor Hot Shoe for Oil Refinery

The hot shoes were constructed using high temperature insulation made from calcium silicate, lined with a ceramic fiber blanket in a steel cradle (A36 Carbon Steel). The shoes were designed for 1500 F and a vertical load range between 25,000 lbs and 32,000 lbs, and the BOP was 10″. The overall diameter including 7″ of insulation is 49 7/8″. Belleville washers are used to hold bolt tension in pipeline with high frequency vibration.

Pre-insulated Pipe Supports

Piping Technology & Products, Inc. custom designed and manufactured 86 pre-insulated pipe supports for a customer. The pipe supports are specifically designed for use in cryogenic lines using polyurethane insulation that can withstand temperatures as low as -51° F. The supports weigh between 17 & 36 lbs. each and are designed for pipe sizes ranging from 2 to 4 in diameter. The clamp and base used with this pipe support are fabricated from A36 carbon steel. Upon customer’s request, a three layer customized paint was applied to the clamp and base.

6000 lb. Load Hot Shoe with Adjustable Lateral Stops for an Oil Refinery

Drawing of Custom Hot Shoe

Piping Technology & Products, Inc. recently assisted in the design and fabrication of a special hot shoe with adjustable lateral stops for an oil refinery in LA. The shoe assembly is designed to support loads up to 6000 lb. and to guide pipes that may reach up to 1200°F. The hot shoe consists of a 12 thick mineral wool insulation, an inner clamp surrounded by four load transfer plates, an outer guiding clamp, and four guide assemblies with PTFE, 25% glass filled, slide plates. The load transfer plates provide support and prevent damage to the insulation between the inner and outer guiding clamp.

The guide assemblies (comprised of the four guides on the shoe and the adjustable stops) are designed to account for lateral, vertical, and axial movement. PTFE, 25% glass filled, slide plates are used to minimize friction caused by movement between the shoe and the adjustable stops. The adjustable stops are fabricated from a 1 x 12 x 19 carbon steel plate with four rods and two angles. These allow for flexibility in adjusting the distance/gap within each guide assembly to control movement.

PT&P recently designed and manufactured over 1,000 Coldshoes for an LNG Plant in Egypt.  These shoes are designed to support loads up to 75,000 lbs. at an operating temperature of -350°F. They are customized to fit pipe sizes of 20”, 24”, 30”, and 36”. All Coldshoes are composed of stainless steel with a Micarta® insulator.  Micarta® is a woven glass fabric laminated with epoxy resin. It is extremely high in mechanical strength, has low moisture absorption and dissipative factors, and has superior electrical characteristics which are exhibited over a wide range of temperatures and humidities.
