Pre-Insulated Cryogenic Supports for a Propylene Dehydrogenation Application at a Petrochemical Plant in Texas

Type: Pre-Insulated Cryogenic Supports
Size: 12” Long Base | 32” Wide Base | 62″ Overall Height | 18” Long Insulation
Material: Polyurethane | Carbon Steel w/ HDG Finish
Design: Operating Temperature -360°F & 42″ NPS
Testing: Standard Quality Control

Piping Technology and Products, Inc. and custom designed two pre-insulated cryogenic supports for a propylene dehydrogenation application at a petrochemical plant in Texas. The insulation is made from a high density polyurethane insulation, with the bearing plates and side bumpers fabricated from carbon steel with an HDG finish. The shoes are capable of insulating and supporting at temperatures as low as -360°F. These were designed to support pipeline diameter of 42” with overall height of 62” diameter. Regular quality control tests were performed with a standard turn-around time.

Over 4,000 Cryogenic Pre-Insulated Pipe Supports Designed for LNG Service

Type: Pre-Insulated Pipe Shoe & Clamp Assemblies
Material: 304 L Stainless Steel | Protective Coating | Micarta® Insulation
Design: 20″ L x 36″ W x 75″ H | 56″ Dia. Pipeline | -459°F
Testing: Load & Pull Tests

PT&P designed over 4,000 supports for LNG service in Texas. These pre-insulated pipe shoe and clamp assemblies were custom designed for cryogenic temperatures with special low temperature grade NP500CR Micarta® insulation. This type of Micarta® consists of a glass fabric with a special formulated epoxy resin. It has excellent physical properties at operating temperatures down to -459°F. It has very low thermal conductivity and has been produced specifically for use in cryogenic applications. The shoes pictured are fabricated from 304 L stainless steel with a protective coating and are designed for a 56″ diameter pipeline. The shoes measure 20″ long, 36″ wide and 75″ high. This project included supports varied in pipe sizes from ¾” to 56″ diameter. A load test was performed prior to shipping this rush order.

Cryogenic Pipe Supports Designed for a Facility in Massachusetts

Cryogenic Pipe Supports Designed for a Facility in Massachusetts

Type: Cryogenic Pipe Supports
Material: Carbon Steel | Polyurethane
Design: -320°F | 36″ – 48″ Dia. | 52″ W x 57″ H x 67″ L

PT&P received an order to custom design 16 cryogenic pipe supports for a contractor in Massachusetts. They needed a pipe forming a T-section lined with insulation and trimmed to accommodate the pipe perpendicular to the shoe length. The overall dimensions of the order are pipe sizes ranging from 36″ to 48″ in diameter, 52″ width and 57″ to 67″ height. Our insulation is designed to support the pipe and 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.

3-Layer Cryogenic Pipe Shoes for a Light Hydrocarbon Chemical Plant in Texas

Type: Pre-Insulated Pipe Supports for Cryogenic Temperatures
Size: 5.5″ of Insulation / Clamps are 12″ wide
Material: Polyurethane Foam and Carbon Steel with HDG Finish
Design: 18″ Pipe and Cryogenic Operating Temperatures
Testing: Standard Quality Control Tests

These 3-layer pre-insulated cryogenic pipe shoes were custom fabricated by Piping Technology& Products for a light hydrocarbon chemical plant in Texas. The insulation foam is made from polyurethane and the rest of the shoe components from carbon steel with HDG finish. The cold shoes are designed for 18″ pipe, the 3-layers of insulation total is 5.5″ thick, the clamps are 12″ wide, and cryogenic operating temperature. Standard quality control tests were performed prior to shipment.

Cryogenic Pipe Supports Designed for a Petrochemical Complex in Louisiana

Type: Pre-Insulated Pipe Supports for Cryogenic Application
Size: 46″ – 52″ Diameter Range | 10 lb. & 20 lb. Density PUF Foam
Material: Hot-dipped Galvanized Carbon Steel | PUF | Polyester Film & Aluminum Foil
Testing: Dimensional and Visual Inspection

PT&P custom designed pre-insulated pipe supports for a cryogenic pipeline at a petrochemical complex in Louisiana. They range in size from 46″ – 52″ diameter and are designed for temperatures down to -20°F. The top portion of the support is 10 lb. density and the bottom is 20 lb. high density polyurethane foam (PUF) insulation. The shoe and bearing plates were fabricated from carbon steel with a hot-dipped galvanized finish. These cold shoes include a vapor barrier comprised of a three layer lamination of polyester film and aluminum foil. Standard quality control tests were performed prior to shipment.
