What stamp is required for a repair organization to meet the National Board Inspection Code?

The R stamp is specifically designated for organizations that perform repairs and alterations to pressure vessels and boilers in accordance with the National Board Inspection Code (NBIC). This certification demonstrates that the organization has met the necessary qualifications and adheres to strict safety and quality standards required by the NBIC for the repair and alteration of these critical components.

To receive the R stamp, a repair organization must implement a quality control program that complies with the NBIC requirements, and the organization must also be capable of conducting repairs in accordance with applicable codes and standards. The R stamp signifies that the organization’s personnel are qualified and that they complete repairs using approved procedures, thereby ensuring the integrity and safety of the pressure vessels and boilers after modifications or repairs are made.

The other stamps referenced, such as the S, P, and T stamps, are meant for different purposes. The S stamp is for manufacturers of pressure vessels, the P stamp is for companies that manufacture pressure relief devices, and the T stamp applies to those who fabricate thermal vessels. Each of these stamps addresses specific areas of expertise and compliance, but none pertain to the functions covered by the R stamp concerning repairs and alterations.
