Apprentices and other aspiring pipefitters do this lengthy training to reach journeyman status. Most states require pipefitters and steamfitters to earn a license to become a journeyman. (A journeyman can do many tasks independently.) The number of hours required to reach that status varies by state, but it typically requires taking a written exam.  This may sound like a lot of work, but it pays off in compensation. A newly minted journeyman’s salary is typically at least double that of an apprentice because he or she can take on so many new responsibilities. Salary will depend on the employer, the area of the country and other variables.  Master status is typically used in reference to plumbers, but pipefitters and steamfitters can also achieve this status. This involves more time and another exam, but it opens the door to get a contractor’s license and open your own business. Master status also gives you the opportunity to train apprentices and helpers.
