Specially Designed Upthrust Constants
Piping Technology & Products, Inc. announces the latest design of their “Horizontal Upthrust” base type constant support. The table or load flange move straight up or down as the weight of the pipe is transferred to the helical coil (spring) via the internal camlinkage. PTFE, 25% glass filled, slide bearings on the four corners eliminate the possibility of binding if undue axial or lateral forces are exerted. Also, PTFE, 25% glass filled, or graphite slide bearings can be added to the table to ease movement along the axis of the pipe. The Big-Ton and Type F Base Constant Supports are still available for other applications.]

Constant Effort Supports for Generating Facilities
Constant Effort Supports in the Field
Piping Technology & Products, Inc. has designed and built thirty-two constant effort supports ranging in loads from eighty to eighty-seven kips with seven and one half inches of total travel on each.Six of the thirty-two are shown in position and they will support critical portions of the heater. The balance in other parts of the plant will support equally critical lines such as main steam and boiler reheat.
Located near Calvert, Texas, this is the second generating facility for Texas – New Mexico Power at this site. Piping Technology & Products, Inc. supplied the same material on the previous installation for this client.

Constants for a Radiant-tube Support System
The photograph above shows a large number of specially designed constant spring supports being prepared for shipment to Chile. These constants are the key component of a reforming furnace, radiant tube support system designed for one of the world’s major engineering and construction firms.
Piping Technology’s engineers designed these units to fit in the limited space available inside the furnace and provided optional bolting patterns so attachment to the supporting structure could be made even if the radiant tube support system assumed a competitor’s design.

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.
