6000 lb. Load Hot Shoe with Adjustable Lateral Stops

6000 lb. Load Hot Shoe with Adjustable Lateral Stops
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.

Cold Shoes with a Load Capacity of 75,000 lbs
September 19, 2003
Cold Shoes with a Load Capacity of 75,000 lbsCold Shoes with a Load Capacity of 75,000 lbs
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.

Cryogenic Supports with Permali® Block
September 16, 2003
Cryogenic Supports with Permali® Block
The above design shows cryogenic supports with Permali® block. Permali® block is a laminated phenolic material from layers of wood impregnated under vacuum and heat with synthetic resin. These pipe shoes can be designed to restrain very high axial, lateral and vertical loads. These shoes are used for LNG pipeline sliding supports with TEF slide plates.

28" dia. Hot Shoes for a Natural Gas Plant
May 16, 2003
28" dia. Hotshoes for a Natural Gas Plant
Piping Technology & Products, Inc. recently designed and manufactured twenty 28″ dia. Hotshoes (high temperature pre-insulated pipe supports) for a natural gas plant in Massachusetts. These supports are assembled with a 5″ thick high-density Calcium silicate insulation layer, in addition to stainless steel, Kaowool, and PTFE, 25% glass filled, slide plate materials. The supports are designed to support loads from 25 kips-50 kips at an operating temperature of 1800 degrees F. The shoes also allow for a travel of 7″ where applicable. PT&P also designed and fabricated rod hangers with variable spring supports for this project.

51,000 lb. load Hot Shoes for a C4 Olefins Complex
December 27, 2002
51,000 lb. load Hot Shoes for a C4 Olefins Complex
Piping Technology & Products, Inc. designed and manufactured 44 shoes consisting of six guided and axial hot shoes, 10 guided hot shoes, and 28 sliding hot shoes. The materials used were calcium silicate, Marinite®, stainless steel plates, and PTFE, 25% glass filled. These shoes were designed for 8″ pipe with 7″ insulation with a load capacity of 5,100 lbs.

Hot Shoes for a Chemical Plant in Texas
November 15, 2002
Hot Shoes for a Chemical Plant in Texas
Piping Technology & Products, Inc. designed and manufactured 60 Marinite® hot shoes for a chemical plant in Texas.
These hot shoes are composed of Marinite®(high-density calcium silicate) and carbon steel. They were made for 8 NPS with 7 insulation. These shoes are used on steam lines, effluent lines, and any other process lines where it’s imperative that thermal energy is not lost through the pipe support. Tests were performed to show outer skin temperature at operating conditions.

Specially Fabricated Pipe Supports

Specially Fabricated Pipe Supports
The photo above shows three different supports fabricated by Piping Technology & Products, Inc. for a petrochemical facility in Indonesia. The smallest support, (lower right) show the interior layer of polyurethane projecting out of the outside layer. This allows the pipe insulation to overlap when installed. These units provide insulation between the very cold fluid inside the pipe and the hot, humid conditions outside. They also support the weight of the pipe and allow for movement due to thermal expansion and contraction. Micarta was used for certain supports which require greater strength.

Insulated Pipe Supports
The photographs above show insulated pipe supports designed for a system being installed in a very cold climate in Russia. The insulating components are inside next to the pipe. The outside components are galvanized steel. In the foreground of the photo at the right are two fixtures which were built for load testing these pipe supports by applying known forces with a hydraulic load cell. Piping Technology & Products, Inc., fabricated prototype units for a Houston Engineering Firm and tested the units. After successful tests a number of similar units were built for shipment to Russia.

Insulated Pipe Shoes for Hot Applications
March 26, 1993
Insulated Pipe Shoes for Hot Applications
Piping Technology & Products, Inc. supplied both “hot shoes” for high temperature lines and “cold shoes” for cryogenic lines in this new plant. The shoes sit on the steel beams of the pipe rack and support the insulated pipe. The bottom photograph shows several of the shoes prior to shipment. The two large cold shoes in the foreground are lined with PUF (polyurethane foam) which functions both as an insulator and as a load bearing member at temperatures as low as –300oF. Hot shoes are lined with calcium silicate or Marinite® which can function up to 1200oF.

Dual Purpose Pipe Shoes for High Temperature Applications

Pipe Shoes for Hot Temperature ApplicationsPipe Shoes for Hot Temperature Applications
The pictures above show insulated pipe supports designed for two very different temperature applications. The top picture shows an inspector checking “hot” shoes for high temperature piping. They have one 180 degree section of the insulation made of foam glass and the other 180 degree made from calcium silicate. Some components are chosen for their insulating properties only, other must both insulate and support the load of the pipe. The bottom picture shows a 54 inch “cold” shoe of galvanized steel with PTFE slide plates on the bottom. Inside the galvanized steel is bonded a layer of polyurethane foam which has been coated with a white vapor barrier. This polyurethane layer provides both insulation and support of the load at cryogenic temperatures.

Color-Coded Insulating Components
January 20, 1993
Color-Coded Insulating Components
The pictures above show pipe supports designed for a system with very cold operating temperatures. The insulating components are polyurethane, which are inside the galvanized steel exterior of the support. At the top left of the picture are the color-coded polyurethane components of a “cold shoe” for a 60” pipe, the top (green) is 14 lb/ft3 density and the bottom (orange) is 20 lb/ft3 density. The higher density material has greater compressive strength but it is a better conductor of heat. The other pictures show finished shoes which have white coating over the polyurethane. Hot shoes, designed for high operating temperatures, are similar but usually have different insulating materials.
