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.

Variable Spring Support Design, Size Selection, Installation & Maintenance Webinar
Date: Thursday, June 1, 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
This Webinar will focus on the different types of variable spring supports and big ton variable spring supports. Learn about the special features available, in addition to the design of a variable support. View how the different coil configurations produce a unique response to an applied load and see how a spring assembly is loaded. Discover the basic steps in selecting a hanger design and the step-by-step process used to size a spring for your application. Learn about the different attachments, testing, and installation and maintenance procedures. View examples of failed supports provided by our Field Service Division and learn why they failed and how to prevent it. Gain knowledge of the valuable tips used when deciding to replace or re-calibrate a variable spring support, as well as adjustments, shutdown, and isolation procedures.
