Each protector is load tested and certified and all necessary documents in this regard are provided.
Each Cast Steel Thread Protector with lifting bail / Lift Nubbin has been load tested and inspected prior to sale. Due to the rough nature in which drill collars are handled, Revata Engineering recommends that the end users carry out frequent inspection to ensure that the bail is not cracked, threads are not damaged and that proper fitting to the connection is possible.
