We have been experts in code welding for decades, having worked with countless industrial customers. Our professional experience includes design and construction of pressure vessels and piping for petro-chemical, nuclear power, aerospace, and general industries.

ASME is a not-for-profit professional organization that enables collaboration, knowledge sharing and skill development across all engineering disciplines, while promoting the vital role of the engineer in society. ASME is best known for improving the safety of equipment used in manufacturing and construction, particularly boilers and pressure vessels. ASME first published the Boiler & Pressure Vessel Code (BPVC) in 1915, which was later incorporated into laws in most North American territories. Today, ASME has more than 600 codes and standards available in print and online.

The ASME Code establishes the requirements for manufacturer certification, quality assurance, design, materials, manufacturing and testing of Power Boilers, Heating Boilers, Pressure Vessels and Nuclear Components. A pressure component designed and fabricated in accordance with this standard will have a long, useful service life, and one that ensures the protection of human life and property.

ASME and NBIC Code StampsPower Boilers (over 15 psi steam, 160 psi water, and temperature exceeding 250F) shall be stamped ASME (S) and National Boiler (N.B.). The “S” stamp by virtue of its description, also covers the “PP” area or pressure piping. Superheaters, economizers, and other pressure parts connected directly to the boiler without intervening valves are considered as part of this scope.

 

ASME-U ASME and NBIC Code StampsPressure Vessels fabrication or weld modifications of unfired pressure vessels require the ASME “U” and National Board Stamp. These rules have been formulated on the basis of design principles and construction practices applicable to vessels designed for pressures up to 3000 psi.

 

ASME-RRepair Certificate of Authorization and “R” stamp, from The National Board of Boiler & Pressure Vessel Inspectors, for the repair and/or alteration of boilers, pressure vessels, and other pressure-retaining items. Detailed requirements are included in the current edition of the National Board Inspection Code (NB_23).
