Big Ton Spring Supports Designed for Propane Dehydrogenation Facility
PT&P custom designed big ton spring supports for a propane dehydrogenation facility in Texas. The components within these assemblies include the spring housing, load columns, travel stops, spring coils and lifting lugs. While both assemblies measure 42” x 24” x 26-1/2”, they were each modified based on independent specifications for operating loads and movement. The first will accommodate a load of 94,261 lb. and 0.085” of movement, while the second will accommodate a load of 102,219 lb. with 0.08” of movement.
This type of support is ideal for applications, such as pressure vessels, that combine very heavy loads with thermal expansion because of the stability they provide. The big tons were tested in the load cell to insure proper operation throughout the entire working range of the coils.

Hydraulic Snubbers Designed for LLDPE Chemical Plant
These Fig. 511 AD long hydraulic snubbers were created for a linear low-density (LLDPE) chemical plant in Louisiana. The snubbers with two (2) rear brackets range in length from 34-⅝” to 49”. They are designed with spherical, self-aligning ball bushings that allow for + 5° of angular motion or misalignment. The snubbers can handle maximum loads varying up to 5520 lb. Cylinder sizes are 1-½” and 2-½” and have a 6” stroke. The hydraulic fluid is petroleum based and the seals are a mix of buna-nitrile and polyurethane and the pressurized hydraulic reservoir allows mounting in any spatial orientation. The snubbers are painted with a primer that utilizes zinc filled powder manufactured by Tnemec. Ⓡ The formulation for the primer is Series H90-97 | Tneme-Zinc. Ⓡ

Cryogenic Pipe Supports Designed for an Air Separation Unit
A total of sixty-four pre-insulated pipe supports were designed for cryogenic temperatures in an air separation unit in China. The units are 12″ in length with 4.5″ thick polyurethane foam insulation. The cold shoes were designed with carbon steel shoe clamps and finished with a black epoxy and include polyethylene slide plates.Standard quality control and dimensional tests were performed prior to shipment.

In this Webinar we explore the details of actual case studies focusing on various signs that indicate if a particular support needs replaced or adjusted. The presentation also covers projects that brought on new standard designs and custom designs for specific applications. And lastly, it includes valuable additions and procedures that extend the typical life span of a pipe support. PT&P’s field service division is available 24×7 in the case of an emergency situation or for a scheduled shut down.
Variable Spring Support with Bronzphite® Slide Plates for a Facility in Canada
PT&P manufactured these F-type variable spring supports for a facility in Canada. The springs are fabricated from A36 carbon steel with a hot-dipped galvanized finish. The variables installed heights range from 11″ to 15″ and are designed for operating conditions up to 4,000 lb. Bronzphite® is best suited for high loads, low velocity applications and where the use of oil or grease is undesirable or unfeasible. The bronze plate acts as the bearing surface, withstanding heavy loads, while the graphite inserts provide a solid, oil-free lubricant. 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.
