In those rare times when a pressure vessel, tube or cylinder cannot be requalified by modern, non-destructive testing methods, hydrostatic testing is an option that FIBA offers. Volumetric expansion testing is available at our new tube manufacturing facility in Millbury, MA. Proof pressure testing is available at our other three locations. Additionally, our Rayne, LA facility can perform direct expansion, hydrostatic testing for single-unit tank car tanks, such as DOT 106A and DOT 110A, which require requalification by a hydrostatic method that measures permanent expansion. Brand new equipment was installed in Rayne, LA in 2012 to perform this testing.
