Flue Gas Duct Damper

Flue Gas Duct Damper

The picture above shows a flue gas duct damper fabricated using Inconel for certain components by the Sweco Fab division of Piping Technology & Products, Inc. Two of these dampers were shipped to Trinidad for installation above the furnaces of an ammonia plant. They have a special refractory lining to withstand the high temperatures of the flue gases. The picture at the left show the linkage of the damper to the motor-driven control system. Each unit weighs approximately 2300 lb. and the openings are approximately 12 feet by 6 feet.

Tanks Mounted on Trucks

The picture above show the replacement of a tank mounted on a truck by the Sweco Fab division of Piping Technology & Products, Inc. In this case the customer delivered the damaged tank to our site so measurements of the mounting could be obtained. The old tank (upper left) was damaged beyond repair when a vacuum was inadvertently created inside the tank.

“Finger Joint” for Howard Franklin Bridge

“Finger Joint” for Howard Franklin Bridge

The picture above shows a 20 foot section of a “Finger Joint” expansion assembly produced by PT&P for the Howard Franklin Bridge from Tampa to St. Petersburg in Florida.

This section is assembled and ready for shipment. Note the galvanized finish on everything except the temporary shipping bars. Each assembly includes four sections having a total weight of 11,227 lb. The fingers on this bridge are tapered to minimize tire damage to vehicles.

3400 lb. Load Type F Spring Hangers for Overseas Refinery Plant

3400 lb. Load Type F Spring Hangers for Overseas Refinery Plant

The photograph above shows a unique combination of Type F variable springs designed by a client engineer to support large skid-mounted pumps. Piping Technology & Products, Inc. fabricated the connecting assemblies which use variable springs inside pods to support the pump skids from the side. The number of pods varies from size to twelve, depending on the size of the pump, and the loads supported by each type F spring vary from 1800 to 3400 pounds depending on the geometry of the assembly. The distance between rods varies from two to three feet. A total of nine units are being exported to refinery project overseas.

Specially Designed Vertical Constants

Specially Designed Vertical Constants

Specially Designed Vertical Constants

The vertical constant is used when piping stress is critical and pipe is subject to vertical movement in excess of ½ inch due to thermal expansion, and also at locations here it is necessary to avid any transfer of stress from support or onto critical terminals or connecting equipment. These constants are manufactured by Piping Technology & Products, Inc.

Custom Designed Vertical Upthrust Constant

Custom Designed Vertical Upthrust Constant

Pictured is a vertical upthrust constant developed for an application where the traditional horizontal upthrust would not fit.

Our Canadian customer searched to find existing products to support a pressure vessel which was to be located in an area with no additional horizontal space. PT&P developed this design and tested a prototype within one month to meet customer’s schedule.

Dual Purpose Pipe Shoes for High Temperature Applications

Pipe Shoes for Hot Temperature Applications

Pipe 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.
