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.

Compact Spring Support Webinar
Date: Thursday, April 6, 2023 - Register for 10:00 am OR 2:00 pm
*Note: Time Zone is CDT * Central Daylight Savings Time / GMT -5h
Live Webinars are 1 PE/PDH Credit for TX Professional Engineers
The Compact Spring Support Webinar will cover key objectives, background, and leading industry problems related to process equipment nozzles (both rotating and non-rotating equipment). First, we will review the challenges involved in the 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 the technical data and sizing program.
