These figure 200 U-type constant springs were fabricated from A-36 carbon steel and range in size from 30-1/2″ to 41″ in height, 25″ to 31″ in width, and 68″ to 80″ in length. These are horizontal constants designed to support piping from below where the base plate is bolted directly to the top of the steel or the foundation using anchor bolts. Loads range from 9,000 lb. to 42,000 lb., and vertical movements range from 6″ to 11″. All the constants went through standard load and travel testing per MSS Standards prior to shipment.

This Webinar will focus on the different types of constant spring supports. Learn about the special features available, in addition to the design of a constant support. View how the different cam/coil configurations produce a unique response to an applied load. Discover 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 adjust or replace a constant spring support, as well as shutdown and isolation procedures.
The featured presenter, Jerry Godina has over 13 years experience as a pipe support designer and manages PT&P’s engineer training development program. He also inspects existing supports, consults on site remediation projects and oversees installation on a regular basis.

This F-type variable spring support was customized with a wire rope isolator for a facility located in Canada. The variable spring was designed for a load of 12,000 lb. The wire rope isolator is essentially a 1.25″ diameter stainless steel rope looped eight times between two chemically conversion coated aluminum alloy retaining bars. The wire rope isolator is effective in vibration isolation and energy absorption.
