December 20, 2010
F-Type Variable Spring Supports
F-Type Variable Spring Supports

An assortment of standard variable spring supports were manufactured ranging in size from 8-5/8″ to 12-3/4″ dia. with installed heights ranging from 9-7/16″ to 18-1/8″. The F-Type pipe hanger assembly is used to support the pipe from below and are typically mounted to concrete pads via anchor bolts or welded to structural steel. The various springs shown are designed for operating conditions ranging from loads of 1750 lb. with .02″ travel to 21,280 lb. loads with .13″ travel. As with all of our variable supports, these were quality checked with a 100% spring coil deflection test and a load cell calibration to set the assembly at the prescribed installed load.

How do I select a pipe hanger?

November 2, 2010

The design parameters that must be considered when selecting a pipe hanger would include operating temperature, operating load, movement, pipe material, available space, and allowable initial load requirements. Once these are known, then you can select an appropriate type of pipe hanger which could be any of the following types including rigid hangers, variable spring hangers, or constant spring hangers.

What is a trapeze hanger?

A trapeze hanger is a support assembly consisting of parallel vertical rods which are suspended from a structure and connected at their lower ends by a horizontal member from which the pipe is supported. It is used for the suspension of pipe from two rods where longitudinal movement due to expansion or contraction may occur.

A total of 40 constant and variable spring supports were fabricated as replacements. Each support was sealed with a neoprene coating over a hot-dip galvanized finish instead of stainless steel. This type of finish will ensure a much longer life-span. The spring supports ranged in loads from 800 lb. to 15,000 lb. with various travel ranges.

Variable Spring and Cro-Moly 3-bolt Clamp Assemblies for a Power Generation Facility

October 5, 2010

Variable Spring and Cro-Moly 3-bolt Clamp Assemblies for a Power Generation Facility

The variable spring and clamp assemblies are fabricated using a combination of carbon steel for the housing and internal components, spring steel for the spring coils, and Cro-Moly (A-387 GR. 22) for the high temperature 3-bolt clamps. This pipe hanger assembly is an example of PT&P’s standard variable spring design wherein multiple coils are arranged in series to produce adequate load carrying capacity and coil deflection to compensate for the anticipated pipe movement. These particular assemblies are capable of an overall load range of 9,320 lb. to 15,970 lb. with a total travel range of 5″. All pipe hanger assemblies underwent standard load and travel testing, 100% deflection testing, and load cell calibration before shipping to a power generation facility.
