QUALITY ASSURANCE


Quality Program Overview

  • National Boiler Service, Inc., feels that it is responsible to provide quality services and products to its customers.

  • This is achieved through clearly defined Quality Assurance procedures which are in compliance with ASME (American Society of Mechanical Engineers) and NBIC (National Board Inspection Code) codes.

  • Our Quality Control department employs experienced, qualified inspectors with high levels of technical ability and training.


  • National Boiler is authorized to perform repair of boilers and pressure vessels (NBIC "R" Stamp), manufacture pressure vessels (ASME "U" Stamp), manufacture and assemble power boiler s (ASME "S" Stamp), and authorized to register boilers and pressure vessels with the National Board "NB".



    • Our QC Inspectors and most of our Supervision have a welding background and have been through our QC training program which has a overview that consists of Visual Examination, Weld Inspection Technology, NBIC Training, ASME Sect. IX, Document Control, Liquid Penetratnt Testing and Communication skills.

    • Welder Certification is maintained with an electronic Welder Management System at the corporate office. All Welders Certifications and Welder Continuity are backed up with a Hard Copy on file.

    • Welder Testing is performed on the Job Site or at our shop with a Qualified Quality Control Inspector (QCI). The Weld Test are recorded on a Weld Test Log. The QCI completes the WPQ and it is sent back to the office in the QC Job Package along with the Welder Continuity.

    • We believe Communication is essential for an ongoing Quality Program. We promote Supervision involvement and implementation of our program which in turn helps maintain a Safe Quality Job.

    • We have an Infrastructure that allows our QC Program to react and respond to any Code or Production Problems that may arise. This approach allows us to have a cost effective balance in Quality, Productivity and aggressive scheduling.
