CHAPTER 4
BOILER INSPECTIONS
4-1
GUIDANCE. The activity operating and maintaining the boiler provides all
material and labor necessary to prepare the boilers for inspection in accordance with
this UFC and the NBBI Code. The activity assists the inspector as required during the
inspections. Exception to this policy occurs when the operation and maintenance of a
boiler is under the cognizance of a contractor. In this case, the contractor provides
material, labor, and assistance. Inspections of boilers located on Navy bases in foreign
countries must comply with this UFC under the constraints of the Status Force
Agreement in effect. Inspectors should not compromise safety issues, but should
exercise restraint when interpreting the fine points of the ASME Code. Obtain further
guidance on foreign inspections from the respective (East or West) NAVFAC Senior
Boiler Inspector or the cognizant geographic EFD of the NAVFACENGCOM serving the
activity.
4-2
EXTERNAL INSPECTION OF BOILERS. Perform external inspections of
boilers in accordance with Part RB-3100, External Inspections of Boilers, of the National
Board Inspection Code. Test safety devices as part of the external inspection. Perform
final testing of safety valves of power boilers on the boiler to which the valve will be
mounted. The operational tests and observations of Chapter 7 are considered to be
part of the external inspection.
4-3
INTERNAL INSPECTIONS OF BOILERS. Perform internal inspections of
boilers in accordance with Part RB-2020, Internal Inspections of Boilers-Power and
order that boiler metal samples and/or ultrasonic tests be taken for their examination to
ascertain the actual condition of the pressure parts.
4-4
BOILERS IN WET OR DRY LAY-UP. In addition to the external and
internal inspections required above, review the lay-up procedures being used to ensure
that they conform to the requirements of Appendix D.
