Steamfitters lay out, assemble, fabricate, maintain, troubleshoot and repair piping systems carrying water, steam, chemicals and fuel in heating, cooling, lubricating and other process piping systems. Steamfitters are employed in factories, plants, and similar establishments, and also by pipefitting contractors or they may be self-employed.
The Steamfitter apprenticeship program consists of on-the-job and in-school training. The program typically takes five years to complete and consists of:
- 8,280 hours of on-the-job training and work experience
- 720 hours of in-school training
Red Seal Exam
At the completion of the in-school portion of the apprenticeship, graduates are given a week of preparation before they write the Red Seal exam for the trade.
Our students may write this exam at the College at the end of the training, or book a separate time to write the exam at the MLTSD office.
What do Steamfitters do?
Steamfitters install, maintain, and repair piping systems that transport high-pressure gases and liquids, including steam, water, and various industrial fluids.
They read blueprints and specifications to determine the layout and configuration of piping systems, ensuring they meet safety and performance standards.
Steamfitters also use specialized tools and equipment to weld, solder, or thread pipes, as well as test systems for leaks and make necessary adjustments to ensure efficient operation.
To be eligible for this program, applicants must:
- Have a sponsor or employer and must be registered through the Ministry of Labour, Training & Skills Development
- Have a minimum Grade 12 high school education or equivalent
- Be at least 16 years of age
This is an apprenticeship program and follows a different application process than regular post-secondary education programs. You cannot apply to this program through ontariocolleges.ca.
Applicants who are registered as an apprentice in a trade should receive a letter from the Ministry of Labour, Training & Skills Development inviting them to apply for schooling. All applications from that point will need their payment processed by the Office of the Registrar & Financial Aid Services at Lambton College.
If you are a registered apprentice and have not received a letter regarding apprenticeship school, please contact your local Ministry of Labour, Training & Skills Development office.
