PT&P custom designed “mini” big ton spring supports to support a large centrifugal fan at a chemical refinery in Texas. They are designed to support a total weight of 33,000 lb. within a maximum space envelope of 4″ wide x 16″ long x 8″ tall. As a result, these mini big-tons were fabricated using coils which could be placed in parallel within their respective frames. Four of the unites were comprised of four inner coils nested inside four outer coils to produce an operating load of 4,478 lb. and an overall spring rate of 2,740 lb./in. The smaller load capacity units were configured of four individual coils in parallel with an operating load of 3,735 lb. and a spring rate of 2,300 lb./in. The frame, load flange and all internal components were fabricated from carbon steel. The spring coils were fabricated from ASTM A-5160 spring steel. All supports were tested through their total working range to confirm load capacity and functionality.

Live Webinars are worth 1 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.
