Vertical F-Type Constants for Power Plant

Piping Technology & Products custom designed and manufactured vertical F-type constants for a power plant in Connecticut.

The 100 type F is a vertical constant designed to support piping from below with minimum space usage. The dimensions of the constant are 26-5/8" high, 10" wide, and 17-9/16" long with an operating load of 280 lbs.

This particular F constant, was unusual in that it was furnished with a vertical spring that attaches below the frame of the constant. In addition to a downward travel of 3", the flange table shifts forward at 1-3/8" to minimize axial movement.

A galvanized finish was applied to the constant to prevent corrosion. The constants can be bolted on or welded to the support or steel underneath.

Big Ton Springs Equipped with Lifting Lugs

Piping Technology & Products, Inc. specially designed and fabricated big ton springs equipped with side lifting lugs to support piping of a 102-megawatt, refinery cogeneration power plant in California.

Under typical circumstances, this type of job application would utilize variable spring hangers, but because of the restricted space, the hangers' size would be too small to support a hot load of 19,068 lbs and cold load of 17,212 lbs. In order to satisfy both the required loads and space, PT&P engineers designed and fabricated figure 500 big ton springs equipped with side lifting lugs. The lifting lugs were attached to allow the big ton to suspend as a variable spring would in the field.

Variable Springs to Meet Travels Needed to Support Furnace Tubes of a Hydrogen Reformer

Piping Technology & Products, Inc.  specially designed and fabricated hundreds of altered Type A variable spring hangers in order to accommodate the special travel and spring rate needed to support the furnace tubes of a hydrogen reformer in Venezuela. In order to accommodate customer specified travel and spring rate, modified spring coils were required. With a travel of 8 7/8, the variable spring hanger casing lengths were increased from the standard size of 32 inches to over 6 feet long. The calculated spring rate is 79 lb/sq in for an operating load of 2,804 lbs. and installed load of 3,505 lbs. The housings are coated with a heat resistant paint, which protects the spring coils from corrosion and high temperatures of the furnace area.
