Rawhide’s facility in Robbins, CA is where trailers are hydro-tested in accordance with the mandatory five year test. Rawhide has the ability to test tubes from 9 5/8” diameter through 22” diameter. Tubes are removed from the trailer, visually inspected, and tested. The trailer chassis is inspected and repaired as required. Then the trailer and tubes are prepared for painting. After painting the trailers are re-assembled installing safeties, valves and manifolds. The finishing touches include DOT decals and placarding. Contact us for a quote. We can supply a substitute trailer during the test period.
