Experience you can’t manufacture.

At Hahn & Clay, our history with ASME (The American Society of Mechanical Engineers) & The National Board of Boiler and Pressure Vessel Inspectors-certified fabrication goes back generations.

Based on the current active ASME & NB stamp holders, Hahn & Clay is proud to hold some of the longest-standing certifications in the United States:
🔹 U Stamp - issued January 20, 1951 - 5th oldest active U Stamp in the U.S.
🔹 S Stamp - issued February 6, 1952 - oldest active S Stamp in the U.S.
🔹 U2 Stamp - issued February 6, 1973 - oldest active U2 Stamp in the U.S.
🔹 R Stamp - 10th R Stamp issued in the United States

These aren't just numbers on a certificate. They represent decades of pressure vessel fabrication, machining, quality systems, engineering knowledge, and hands-on experience.

Since 1908, Hahn & Clay has continued to build on that experience while investing in the people, equipment, and capabilities needed to serve today's most demanding industries.

115+ years of experience. Generations of ASME-certified fabrication.

That's experience you can't manufacture.

Not every job that comes through our machine shop needs one of the biggest machines in the building.

At Hahn & Clay, our smaller machining equipment gives us the flexibility to efficiently machine smaller components while maintaining the same attention to precision and quality we bring to our large-capacity work.

From large-scale components to smaller parts, our machine shop is equipped to handle a wide range of machining needs — all under one roof.

Big or small, we have the equipment, experience, and capability to get the job done.

When the work can’t come to the machine shop, we bring the machine shop to the work.

Hahn & Clay’s team provides on-site machining capabilities for equipment and components that are too large, difficult, or critical to remove from service.

Our field machining capabilities allow us to support customers with work such as fl**ge facing, line boring, milling, keyway work, and other precision machining applications—helping minimize downtime and avoid the cost and logistics of removing large equipment.

With decades of experience in heavy industrial machining, our team is equipped to tackle challenging field work across the Gulf Coast and beyond.

Big equipment. Tight tolerances. On-site solutions.

That’s Field Services from Hahn & Clay.

At Hahn & Clay, "small" is all relative.

While our Tuda lathe is one of the smaller lathes in our machine shop, it's significantly larger than what you'll find in many machine shops. With the capacity to machine parts up to 36" in diameter and 38' between centers, it's built to handle long, precision-machined components for a wide range of industries.

This video highlights one of the many capabilities that allow us to deliver precision, quality, and reliability on every project. Whether it's a one-off repair, OEM replacement component, or production work, our machining team has the equipment and experience to get the job done.

At Hahn & Clay, we combine over a century of manufacturing expertise with the equipment to tackle jobs that many shops simply can't.
