A pipefitter is a tradesperson who installs, assembles, fabricates, maintains, and repairs mechanical piping systems. Piping can consist of copper, PVC, CPVC, polyethylene, and galvanized pipe, which is typically glued, soldered, or threaded. Plumbers, pipefitters, and steamfitters learn on the job through an apprenticeship, but also go through licensing and accreditation. According to the Occupations Handbook, there are at least 950,000 pipefitting jobs in 2018. The pipefitting industry is expected to grow 21% from 2012 to 2022, faster than the average for all occupations. Construction of buildings and the need for new septic and mechanical systems should drive demand for qualified workers. The Pipefitters Handbook has been THE indispensable reference for pipefitters of all levels for about 50 years. It continues to sell well, despite its age and outdated appearance. Here, in one book, the authors are modernizing this work for the entire pipefitting trade. There will be much more information on plastic pipes and tubing, which was NOT included before. The content will include modern materials, standards, and requirements. All state exams are taken into consideration. The authors will also include true/false and multiple-choice questions – the type students studying for the certification will see on their official exams. Tools and instruments are included to familiarize the individual with the labor-saving devices and their correct utilization. This is the perfect resource for all those entering the trade.
