Prefabricated Piping, Modules and Skids

We fabricate complete piping skids – from the bases to the entire piping schematic – featuring both bolted or welded connections. Our design and engineering expertise allow us to successfully evaluate your design and suggest ways to minimize your package’s size to improve it’s operating efficiency. This initial phase allows our engineers to work closely with our fabrication team to ensure a quality product is delivered.

We are ASME accredited and routinely perform work to B31.1, B31.3 and B31.5. Prefab piping is just one aspect of our work as we integrate and link multiple skills and disciplines into the construction of modules and skids.
