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.
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.
