A Houston shop for piping, welding, and field fabrication.

John Graziano

Before founding the company, John Graziano worked as a worldwide, internationally known fabricator and erector for oil and gas and engineering companies. Over more than twenty years he traveled the world on fabrication projects — then brought that standard home to a Houston shop. The company site is mechanicalpiping.com.

Grazco, LLC is a Houston-based company providing full-service mechanical piping, industrial welding, structural steel, and field installation. For years we have serviced refineries, chemical plants, and oil and gas companies throughout the world. Customers demanded fast, reliable quality service and received exactly what they expected.

The cornerstone of the company is a commitment to safety, craftsmanship, and integrity. Employees have performed so many extraordinary jobs over the years that the extraordinary has become our standard. Whether the project is a small shop job or a large turn-key shop and field installation, the same crew culture applies.

We remain affiliated with AWS and AISC. Piping is performed to the ASME codes our customers specify, including B31.1, B31.3, and B31.8, with 100% x-ray welds available when the job requires it. Vessel and tank fabrication is scoped on the pressure vessels page. Where the crews drive is on areas we serve.
