PT&P Custom Designs and Fabricates Big Ton Springs Equipped with Lifting Lugs


Piping Technology & Products, Inc. specially designed and fabricated big ton springs equipped with side lifting lugs to support piping of a 102-megawatt, refinery cogeneration power plant in California.

13"x 23"x 9-1/2" big ton springs equipped with side lifting lugs. 

Under typical circumstances, this type of job application would utilize variable spring hangers, but because of the restricted space, the hangers’ size would be too small to support a hot load of 19,068 lbs and cold load of 17,212 lbs.  In order to satisfy both the required loads and space, PT&P engineers designed and fabricated figure 500 big ton springs equipped with side lifting lugs. The lifting lugs were attached to allow the big ton to suspend as a variable spring would in the field.

The big ton springs are comprised of A-36 carbon steel and built at 13"x 23"x 9-1/2" with a downward travel of .232". The job was completed within two days to meet the customer’s quick turn requirements.
