These compact spring supports were custom-designed to support large diameter piping at a chemical plant that manufactures ethylene, propylene, butadiene, benzene, propylene oxide, styrene monomer, and other derivatives and gasoline-blending products. They are designed for large loads (13,623 lb. to 24,038 lb.) and a small confined space with limited thermal movement (from 0.2″ to 0.3″). Compact spring supports (or disc springs) minimize excessive loads on sensitive equipment, so these types of spring support the same load as a conventional variable spring but with a smaller “working range” and utilizing 25-50% less space. They are ideal for locating under equipment flanges or other locations where space is limited. The housing is fabricated from A-36 carbon steel and hot-dipped galvanized to protect against corrosion. They have an installed height of 13″ – 15″ and are 21″ in diameter. The “disc springs” are engineered using stainless steel. Each assembly underwent load testing and other NDE prior to shipment.

The Compact Spring Support Presentation was presented by DST and covered key objectives, background and leading industry problems related to process equipment nozzels (both rotating and non-rotating equipment). It reviewed the challenges involved in design and analysis of piping with respect to process equipment nozzles. This presentation also discussed the types of chronic problems and failures related to process equipment nozzles and present (or introduce) the Compact Spring Support as a solution. During the presentation, the DST team explained 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. It also took a quick look at DST technical data and sizing program.
