Task B‑6 Installs, maintains, troubleshoots, repairs and tests valves.
Task Descriptor
Valves are commonplace and widely used in industry. The failure or improper selection of these pieces of equipment can shut down plants and cause buildings to lose heat. This failure can cause the release of hazardous materials into the environment, at a chemical plant, prevent a refinery from meeting a critical production deadline, or create a dangerous situation by interrupting the daily operation at a health care facility. Steamfitter/pipefitters install piping systems and valves that are part of those systems.
Industry Expected Performance
The task must be performed according to the applicable jurisdictional codes and standards, including Manufacturers Standardization Society (MSS) and American National Standards Institute (ANSI). All health and safety standards must be respected. Work should be done efficiently and at a high quality without material waste or environmental damage. All requirements of the manufacturer, client specifications and the AHJ must be met.
At a journeyperson level of performance, all tasks must be done with minimal direction and supervision.

Task B‑7 Installs, tests, maintains, troubleshoots and repairs heat tracing systems.
Task Descriptor
Tracing accompanies existing piping systems to facilitate the delivery of the medium. Tracing systems are made with a variety of materials such as carbon steel, stainless steel and copper. Steamfitters/Pipefitters install, attach, diagnose, repair and energize tracing systems. These systems can be installed during construction or after completion. In liquid-filled tracing systems water, glycol or a combination of both is used as a medium when consistent temperature control is required. Steam is used when high levels of heat energy are required.
Industry Expected Performance
The task must be performed according to the applicable jurisdictional codes and standards. All health and safety standards must be respected. Work should be done efficiently and at a high quality without material waste or environmental damage. All requirements of the manufacturer, client specifications and the AHJ must be met.
At a journeyperson level of performance, all tasks must be done with minimal direction and supervision.
