These U-type upthrust constant supports are designed to handle 6″ of total travel and loads of 5,677 lb. and 4,956 lb. The load flange is modified to hold six ball transfer units for each support. The ball transfer units are used to decrease the coefficient of friction to 0.05 compared to using the standard PTFE, 25% glass filled, which is 0.15.

Multiple Constants During Inspection

The horizontal upthrust constants (Fig. PTP200-U) were fabricated from carbon steel and chrome-moly for a Heat Recovery Steam Generator. The constants range in sizes PTP-200 size 3 to 65 and weigh from 24 lbs to 1,300 lbs. They support loads of 100 lbs to 8,100 lbs. The constants support pipes and equipment subjected to vertical movement due to thermal expansion at locations where transfer of stress to other supports or equipment can be critical. Horizontal upthrust constants are utilized in areas where horizontal travel is unacceptable. Standard testing was completed for performance and quality assurance.

Piping Technology & Products, Inc. designed and manufactured sixty nine Upthrust Constants for a construction site in Chad, Africa.  They range in constant size from 31-61 and are composed of A36 carbon steel. The applicable loads and travel for these constants are from 1,700 lbs.-17,000 lbs. and 3”-8”, respectively. The installed height for this job was much higher than our standard constants, so we had to customize them. By extending the height of our standard constant with an additional angle we were able to meet the installed height.

Piping Technology & Products, Inc. designed and built two, 68″ in height 100 U-Type constants for a power plant in Mexico. The vertical upthrust constants were designed to support 48,500 lb. each with a total upward travel of 3″. In order to prevent buckling of the constant housing, each constant was designed with five C7 x 14 3/4 lb. channels and a base plate of 26 3/8″ x 33 1/4″. These unique 100 U-Type upthrust constants were custom designed by PT&P to accommodate limited horizontal space requirement. The constants will be placed opposite to each other on a beam capable of supporting 99,000 lb. load of the pipe, plus the weight of the constants.

Specially Designed Upthrust Constants

March 8, 1994
Specially Designed Upthrust Constants
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.]

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.
