PT&P Shop Tour

Ptp Manufacturing Plant

As our long-time customers know, after many years on Long Drive here in Houston, PT&P purchased 7.2 acres on Holmes Road in Houston, Texas in the summer of 1987. After upgrading the electrical systems, PT&P and Sweco Fab, Inc., PT&P’s ASME code fabricated shop, relocated to this new facility. Since that time, PT&P has continued to expand and improve its work space at the Holmes Road facility.

PT&P extends an invitation to all its customers to come to Houston and visit the plant. This is the best way to see our people, our facilities, and the many capabilities we have to serve you.
