Location

Located just outside of Titusville, Pennsylvania – home of the first commercial oil well – Colonial Machine Company continues to support the power industry and others through the manufacture of piping components, valve components, and more.

Family Owned and Operated

In the 1960’s, Glenn Mallory began as a pipe salesman, learning the ins and outs of his business. He saw that, as more and more companies were entering the nuclear field, there was a niche to fill. When companies struggled to find people to make special pipe fittings, he began fabricating them himself, and out of this business Colonial Machine was born. Glenn’s children joined their father and ran the business for over four decades. The family business is now operated by Glenn’s grandchildren, and has expanded to a 60,000 square foot facility employing over 20 people.
