Replacement of a Constant Spring Hanger

A large refinery plant located in Pasadena, TX called upon Piping Technology & Products, Inc. to aid them in the immediate replacement of a 5400 Lbs, 7 1/2″ travel vertical constant spring hanger used to support a Coker drum.

The constant spring hanger was damaged during servicing. The reliability engineer from the refinery contacted PT&P Wednesday evening to request an inspection by a PT&P field services representative. The following morning PT&P’s field services representative arrived on-site, inspected the damaged constant spring hanger and suggested that a replacement would be most efficient and cost effective. With the existing nameplate bolted to the constant, PT&P was able to easily locate the original design of the constant.

The original design, along with the convenience of the component parts being in stock inventory, allowed PT&P to quickly manufacture a replica of the constant and ship it out on the same day by 6 p.m.

In the past, lead times for delivery of constant supports averaged 6-8 weeks, however, through the process of maintaining stock components of interchangeable parts, lead time has been drastically reduced. Piping Technology & Products, Inc. maintains a large inventory of stocked constant support assembly components that allows them to quickly assemble and ship to customers on demand, especially in emergency/quick-turn situations.
