NOTE: The following description is a GENERAL Overview of this career and not a description of a particular job posting.
Pipefitters are typically tasked with installing and maintaining high and low pressure pipe systems, supports, and related equipment aboard waterborne or Naval vessels. A pipefitter is often required to lay out and fabricate full-scale pipe systems (including fire or sprinkler systems) prior to installation using blueprints and templates. Pipefitters must be familiar with the use of basic shop tools and machinery such as grinders, power and hand cutters, presses, bending machines, die and pipe threading machines. Pipefitters also must be familiar with various pipe joining techniques such as soldering, welding, and brazing.
Most pipefitter careers require training in vocational schools, related on-the-job experience, and/or an associate's degree. A recognized apprenticeship program may be associated with these occupations.
Previous work-related skill, knowledge, or experience is typically required.
