Geiger Brothers has received Certificate of Authorization from the National Board of Boiler and Pressure Vessel Inspectors to perform metallic repairs and alterations of boilers, pressure vessels and other pressure-retaining items.
The “R” symbol stamp is a triennial endorsement on loan from the National Board, to be used within the scope and limitations under which it was issued. The “R” Stamp is required for all welding repairs performed on pressure vessels, defined as any tank or vessel designed for operation above 15 psig. Organizations may be authorized to perform repairs only or both repairs and alterations, metallic and/or non-metallic, in shop or field or in both.
The “R” Certificate allows Geiger Brothers to perform metallic only repairs and alteration to a variety of non-fired pressure tanks and vessels both in its Fabrication Shop and on field projects and to apply the “R” Symbol stamp to work completed.
The nature of pressure systems merits stringent controls over those performing repairs and alterations. Qualifying for an “R” Stamp required Geiger Brothers to outline all procedures and demonstrate competence performing actual repairs.
Geiger Brothers first was required to have and maintain agreement with an Authorized Inspection Agency (AIA) and chose HSB Global Standards, based in Hartford, Connecticut.
Certification then required that Geiger Brothers develop a stamp work-specific written quality system that complies with the requirements of the current edition of the National Board Inspection Code (NBIC). Geiger Brothers must maintain the current edition of all three parts of the NBIC and have available a copy of the American Society of Mechanical Engineers (ASME) code of construction appropriate for the intended scope of work.
The quality system, facilities and welding personnel qualifications then were subject to audit (referred to as a Joint Review) by a representative of the National Board and agents of the inspection agency.
The Geiger Brothers quality system shall provide for constant control of the certification and the “R” Symbol Stamp. Each repair or alteration must be documented thoroughly and related documents kept on file. The certificate is valid for three years, at which time Geiger Brothers will be subject to verification again by audit that compliance is being maintained and the Certificate of Authorization may be retained.
