Additional Information

Other Essential Skills:

Working with Others

Steam‑ and pipefitters work with others most of the time. They liaise with other steam‑ and pipefitters to ensure that fittings and hangers are available and are put up. They work mainly with welders to assemble fittings prior to welding, but may also work with pipe insulators and electricians. They coordinate the arrival times of crane operators when necessary. They work closely with apprentices to obtain assistance and to offer both technical training and safety information. Coordination of work with others is a key part of the occupation.

Continuous Learning

Continuous learning is essential for steam‑ and pipefitters as they must keep up‑to‑date with regulatory requirements and codes that are periodically revised. Also, they must stay current on technological advances in their field to select the most appropriate equipment and materials and be able to perform proper installations.

Impact of Digital Technology

All essential skills are affected by the introduction of technology in the workplace. Steam‑ and pipefitters’ ability to adapt to new technologies is strongly related to their skill levels across the essential skills, including reading, writing, thinking and communication skills. Technologies are transforming the ways in which workers obtain, process and communicate information, and the types of skills needed to perform in their jobs. For example, the use of technology, such as project management and computer‑assisted design (CAD) software, is increasing in these occupations. In addition, self‑employed workers may also require a broad range of computer skills to operate software applications that help them bill and communicate with customers, track costs and revenues and produce financial summaries.

Technology in the workplace further affects the complexity of tasks related to the essential skills required for this occupation. Not only do workers need the skills to use increasingly complex and specialized software applications, but sophisticated piping installations have also increased the complexity of schematics and other diagrams. In contrast, electronic databases, CD‑ROMs and keyword search functions make it easier to find information, such as diagrams and specifications. Workers can calculate costs, material requirements, conversions, electrical resistances, volumes, rates and offsets using Web‑based applications, specialized software and hand‑held devices, such as personal digital assistants (PDAs).
