Custom Constant Spring Hangers and Pipe Clamps

The constant spring hangers are manufactured from A36 carbon steel and have custom 4-bolt pipe clamps due to heavy loads. The dimensions are 40" length x 18" width x 85" height and are designed for a 1,784 lb. load with 10" of travel. The constants will be used to support radiant inlet manifolds and have a unique paint applied due to the highly corrosive condition. The entire pipe hanger assembly went through load and travel testing prior to shipping.

9200 lb. Load Type “E” Constant Hanger Assemblies

PT&P designed and manufactured forty PTP 200- type “E” constant hanger assemblies with pipe sizes ranging from 36” to 62” for an oil refinery in Canada.  These constant hanger assemblies are designed to support and allow vertical movement of the field pipe during thermal expansion. The constants have a load capacity of 2800 lbs. to 9200 lbs. and a 3”-7” travel range. To assure quality, standard load testing was performed on the constants prior to shipping. The assemblies’ components consist of a constant load hanger, a rod and a clamp. The constants are fabricated from ASTM A36 carbon steel and the rod and clamp were manufactured from ASTM A240, Gr. 304 stainless steel.

C-Type Constants

Piping Technology & Products, Inc. designed and manufactured 70 horizontal, C-type constants for a furnace application located in Venezuela.

The sizes of the Figure 200 constants ranged from 32 to 64, with a total travel of 4.5 to 10.5, and loads varying from 1,149 to 5,149 pounds. The constants are provided with a custom designed PT&P Figure 270, which consists of a double lug horizontal traveler versus a single lug. Within the horizontal travel, the constants are designed to handle 8 of horizontal movement and support a rod that remains vertical throughout pipe movement.
