G-Type Variable Spring Assemblies Designed for an Oil & Gas Refinery in Texas

PT&P designed these G-Type variable spring support assemblies, along with a 24” pipe shoe and hanger for an oil and gas refinery in Texas. Each item is designed with a center to center of 36” and an elevation difference up to 72”. The spring supports consists of a G-type variable spring, all threaded rod, clevis, lifting lugs, welding lugs and clevis pins. They are designed with an operating load range from 1,700 lb. to 10,500 lb. and a movement range of .02” to .19” up or down. Standard load and travel testing was completed prior to shipment.

Big Ton Spring Supports Designed for Propane Dehydrogenation Facility

Big Ton Spring Supports Designed for Propane De-Hydrogenation 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.

Variable Spring Support with Bronzphite® Slide Plates Designed for a Facility in Canada

Variable Spring Support with Bronzphite® Slide Plates Designed 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.

U-Type Constant Spring Supports Designed for an LNG Plant in Canada

PT&P designed U-Type constant spring supports for an LNG plant in Canada. These are horizontal constants designed to support piping from below where the base plate is bolted directly to the top of the steel or the foundation using anchor bolts. These specific constant springs are designed to support an operating load of 67,420 lb. with 6” of total upwards travel. The constants are fabricated from galvanized carbon steel for protection against corrosion. Standard load and travel testing were completed to ensure the quality and performance of these constants.

300 Variable Spring Supports Designed for a Furnace Application at a Methanol Processing Facility

300 Variable Spring Supports Designed for a Furnace Application at a Methanol Processing Facility

PT&P designed and fabricated 300 variable spring supports for use in a furnace within a methanol processing facility in Mexico. We manufactured the ”housing” of these variable springs using seamless pipe (in order to prevent the springs’ coils from rubbing against the ”weld seam” of a standard pipe) so that the exact spring rate (+/- 5%) can be calculated without discrepancies or variations. The reason that an accurate spring rate is important is because furnace springs function as a ”scale” in order to determine the weight of the radiant coils within the unit. These springs are coated with red oxide primer to protect against corrosion. We manufactured these furnace spring assemblies for an operating load of 1,036 lb. and a movement up to 8 1/2″. Each spring is traceable to test data and tagged with its’ unique spring rate along with other standard information use for identification.

Furnace SpringsJoin us for this Webinar focusing on the unique design aspects of pipe supports and expansion joints operating in furnace applications. See how these non-standard designs impact the overall construction and fabrication processes. Learn the differences between standard supports and those specifically used in furnace applications. View the in-depth testing processes and learn what to watch for during inspection and maintenance intervals.

The featured presenter, Jerry Godina has over 15 years experience as a pipe support designer and manages PT&P’s engineer training development program. He also inspects existing supports, consults on site remediation projects and oversees installation on a regular basis.

 

Compact Spring Supports Designed for an Oil Refinery in Minnesota

Compact Spring Supports Designed for an Oil Refinery in Minnesota

These compact spring supports were custom designed for an oil refinery in Minnesota. Typically, compact spring supports are used to support large loads but small movements relieving process equipment nozzles from overloading. In this case, the springs are designed to support loads of 5,605 lb., 4,747 lb. and 1,250 lb. and movements of 0.133” and 0.029” upward and 0.199″ downward, respectfully.

Compact spring supports utilize engineered Belleville (disc spring) washers. Since these spring supports contain disc springs, both the support housings and the springs contained in the housings are made from 304 stainless steel. Corrosion resistance is significantly increased by using this combination. Glass coatings can also be applied to both the housing and springs to make the support system virtually impervious. Each assembly underwent load testing prior to shipment.

Upcoming Webinar: Compact Spring Support

This webinar is over, view the recording at: http://info.pipingtech.com/compact-spring-support-webinar

PT&P partnered with Disc Spring Technology (DST) and is now manufacturing the compact spring support.

Disc SpringsThe Compact Spring Support Webinar will cover key objectives, background and leading industry problems related to process equipment nozzels (both rotating and non-rotating equipment). First we will review the challenges involved in design and analysis of piping with respect to process equipment nozzles. Secondly, we will discuss the types of chronic problems and failures related to process equipment nozzles and present (or introduce) the Compact Spring Support as a solution. During our discussion, we will explain why chronic problems with process equipment exist, describing current design practices as they relate to industry code standards and how the Compact Spring Support addresses these problems directly and effectively. And finally, we will take a quick look at DST technical data and sizing program.
