What is a Pipefitter

Pipefitters are welding professionals who install new piping systems. They must possess a wide range of technical skills related to their profession. As a pipefitter you will install and fix the pipe systems, as well as use different skills, tools, and equipment to and mark the tools according to certain specifications and regulations.

There are many different settings Pipefitters may choose to work in. Many of them serve in power plants or industrial settings, installing and adding adjustments to the company’s pipe systems. Some of them may choose to enter the HVAC Program, where their skills will be applied in residential or commercial properties, visiting offices, apartment units or homes.

Pipefitters typically spend most of their time outdoors laying pipes for different applications such as gas, chemical and oil companies. This job requires a great physical stamina and strength to endure long hours of being hunched over piping systems or standing on ladders to reach pipes that are in higher areas.
