U-Bolts /Coated U-Bolts
and PB Rod Pipe Support Material

Patriot Bolt provides high-quality coated U-Bolts for oil & gas applications. We offer custom standard and custom coated U-Bolts™ at competitive prices, with quick turnaround and same-day shipping for many products.

Our U-Bolts are designed to provide superior performance in corrosive and moist environments, which protects process pipe support points in refineries, chemical plants, and offshore platforms. In these environments, uncoated U-bolts and pipes corrode, leading to weaknesses in the pipe walls and leaks.

Patriot Bolt also provides custom PB Rod pipe support pad materials that prevent corrosion due to the crevice created between the pipe and beam.  Available in half round configuration or cut and drilled to match the U-Bolt Pattern.
