Custom Designed Big Ton Spring Supports for a Propane Dehydrogenation Application in Texas

November 20, 2017

Type:	Big Ton Spring Supports
Size:	42″ x 24″ x 26 1/2″
Material:	Carbon Steel
Design:	94,261 lb. Load & 0.085” Movement
Testing:	Standard Load Tests

PT&P custom designed big ton spring supports for a propane dehydrogenation application at a chemical plant in Texas. The components within this assembly include the spring housing, coils, name plates, pressure plate, and load indicator. While both assemblies measure 42” L x 24” W x 26-1/2” H, it was modified based on independent specifications for operating loads and movement to accommodate a load of 94,261 lb. and 0.085” of movement. This type of support is ideal for applications, such as supporting pressure vessels that combine very heavy loads with thermal expansion because of the stability they provide. The big ton was tested in the load cell to insure proper operation throughout the entire working range of the coils.

G-Type Variable Spring Supports Designed for a Coker Replacement Project

April 12, 2015

PT&P fabricated PTP-6 G-type variable spring supports for a coker replacement project in Kansas. The variables are comprised of two standard spring housing joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions which allows for use in applications with limited space or interferences. They are 50″ in length, designed for an operating load of 15,000 lb. and fabricated from carbon steel with a hot-dipped galvanized finish. All variable assemblies underwent standard load and spring testing prior to shipment.

Bolt Cradle Supports with Slide Plates Designed for a Combined Cycle Facility

July 14, 2014

PT&P custom designed Fig. 900 bolt cradle supports with slide plates in 3 weeks for a combined cycle facility in Virginia. The supports are fabricated from carbon steel with a hot-dipped galvanized finish. They are 20″ long and range from 1’2-3/8″ to 1’6-7/8″ in height. The cradle supports are designed for an operating temperature range from 300°F to 530°F and are capable of supporting loads ranging from 1,340 lb. to 3,774 lb. with 0.05″ to 3.33″ of axial movement.

PT&P partners with Disc Spring Technology to offer you the Compact Spring Support

June 9, 2014

The compact spring is ideal for applications with large loads and limited space.

– Minimizes excessive loads on sensitive equipment
– Same load for smaller working range while consuming 25-50% less space
– Ideal for locating under equipment flanges
– Reduces design time, maintenance cost and accidents

1,328 Hold-Down Pipe Clamp Supports Designed for Insulated Pulsating Gas Pipelines

April 20, 2014

PT&P fabricated 1,328 hold-down pipe clamp assemblies for insulated pulsating gas pipelines. They are fabricated from carbon steel and designed with PTFE slide plates and kinetics-vibroisolating pads. The hold-downs are designed for 2″ to 8″ diameter plipes and operating temperatures ranging from -20°F to 750°F.

G-Type Variable Spring Supports Designed for a Paper Manufacturing Plant

April 5, 2014

PT&P designed G-Type variable spring supports for a paper manufacturing plant in Minnesota. The variables are comprised of two standard spring housing coil subassemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions which allows for use in applications with limited space or interferences. The variables are fabricated from carbon steel with a hot-dipped galvanized finish. The assemblies were designed for a total operating load of 1,348 lb. with an upward design travel of 0.8013″. Each assembly underwent a standard load test prior to shipment.

U-Type Constant Spring Supports Designed to Support Ducts in an Acid Plant

March 23, 2014

U-Type constant spring supports were designed to support ducts in an acid plant. The constants are fabricated from carbon steel, galvanized and painted for extra protection against corrosion. The U-type constants are designed to support piping from below. The base plate is 25-7/8″ wide and bolted directly to the top of the steel or floor. Thep assemblies measure 84″ in length and 22-1/2″ in height. They only have vertical movement subjected by 6-1/2″ total upwards travel and are capable of supporting a 13,489 lb. load. The constants underwent standard spring testing prior to shipment.

Variable Spring Supports Designed for a Coker Unit in an Oil Refinery
