Restamping boilers

When the stamping on a boiler becomes indistinct, the inspector shall instruct the owner or user to have it restamped. Request for permission to restamp the boiler must be made to the chief inspector and proof of the original stamping must accompany the request before authorization by the chief inspector. Restamping authorized by the chief inspector may be done only by an inspector, and must be identical with the original stamping, except that it is not required to restamp the American Society of Mechanical Engineers Code symbol. Notice of completion of such restamping must be filed with the chief inspector by the inspector who stamped the boiler or pressure vessel, together with a facsimile of the stamping.
