Pipeshields insulated supports 138055

Pipe Shields, Inc., a division of PT&P designed pre-insulated pipe supports for a high-temperature pipeline at a petrochemical plant overseas. This style of insulated support is designed to be compact, easy to install and eliminate the need for field welding. The insulation is 5-1/2″ thick utilizing 18 lb. and 28 lb. pcf high-density calcium silicate. The “hot shoes” are fabricated from carbon steel and hot-dipped galvanized for corrosion protection. They are rated for temperatures from +40°F to +1800°F. Q.C. inspections and dimensional tests were performed before an expedited shipment.

Such insulated supports are used for chilled water, hot water, and steam line applications in industries ranging from pharmaceutical, semiconductor, paper mills, chemical plants, data centers, biofuels, and food processing to name a few. Piping Technology and Products, through its subsidiary, industry leader, and pioneer, Pipe Shields, has supplied to all these markets in the USA and internationally for over 45 years. Most recently, we made a large investment to automate manufacturing in our Houston plant to increase throughput and yield to support our customers’ needs for just-in-time deliveries reducing cash requirements on projects.

Cryogenic Pipe Saddles with Micarta® Insulation for LNG Service

March 9, 2021

PT&P manufactured cryogenic pipe saddles for LNG transportation pipelines. These types of insulated supports have been utilized in LNG plants around the world. Insulated supports are also used on cold piping in semiconductor plants or plants that make batteries to eliminate condensation. This particular type of insulated pipe saddle assembly was fabricated with a carbon steel base plate, 304L stainless steel saddle, and an insulation block. The overall size ranges from 25” x 19” x 12-¾” to 29” x 25” x 13-3/8” and designed to isolate the pipe temperature from below the structure. These pipe shoes were manufactured to support pipe sizes ranging in diameter from 36″ to 42″ NPS.

High-Temperature Pre-Insulated Pipe Supports Designed for 42″ Dia. Pipelines

February 2, 2021

Pre-Insulated pipe supports were designed for high-temperature service at an oil refinery for a client that specializes in the engineering and design of fired heaters, furnaces, pre-heaters, and heat recovery systems. These high-temperature pipe supports were fabricated from carbon steel and designed for pipe sizes ranging in 36” – 42” diameter and are not only used for new construction but also upgrades and revamps. The “hot shoes” were designed with the addition of “Spring Washers” (not shown here) to maintain consistent clamping force when the pipe expands and contracts. The insulation is 3″ thick and comprised of High-density Calcium Silicate (asbestos-free) structural inserts treated with water repellant. Standard quality tests were performed before shipment. Our hot shoes are used extensively in Refineries, Styrene Plants, Hydrogen Plants, LNG Facilities, Semiconductor Fabrication Facilities, and General Building Construction.
