Compact spring supports (also known as disc springs) were custom-designed for a chemical plant in the agricultural industry. We design each compact spring for specific applications. Usually, they are used in “tight” spaces where the conventional variable spring is too tall to fit the allowable space between the pipeline and supporting steel structures. In general, compact springs serve the same function as a conventional variable spring, to relieve vibration and stress in the pipeline and associated equipment. The springs supplied here are designed for loads ranging from 5,038 lb. to 15,144 lb. and spring rates from 5,904 lb./in. to 44,455 lb./in. Also, these disc springs were designed for thermal movement ranging from 0.011” to 0.46”. The assemblies are fabricated from 304 stainless steel and include Bronzphite® and stainless steel slide plates to lower the coefficient of friction due to lateral movement. Since there is lateral movement, the conventional variable spring would require “internally guided load columns”, however, these units incorporate a “guiding” feature within the spring’s design. They have an installed height of 10-1/2″ – 26”. Each assembly underwent load testing and other NDE and visual inspection by our QC department before shipment. Applications such as Skid Mounted Process Equipment, Pump and Control Skids, Skid Plants, and other types of Skid Packages where space is extremely limited are ideal applications for Compact Springs.

Engineered Spring Supports (Practical, Hands-on Approach) Webinar
Date: Thursday, June 2, 2022 – 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
Learn how the theoretical applications of spring supports are put into use in the real world. We will start with a review of the working principles of both variable and constant springs. See how brand new spring looks at delivery, and review installation guidelines. Learn the key points to review through the total installation process and subsequently when the springs are in operation. See how to determine if springs need adjustments, re-calibration, refurbishment, or replacement. View in field examples, shutdown, and isolation procedures. See the selection process required when there are significant changes to the operating condition.
Upcoming Webinars:
