Mountaineer Fabricators, Inc. designs and manufactures ASME pressure vessels, pre-fabricated piping assemblies and modular skids.

The company was purchased from the original family owners in 2004 and moved into the newly constructed facilities in Nitro , West Virginia .

Mountaineer Fabricators, Inc. is an ASME certified manufacturer with capabilities to both fabricate and repair pressure vessels, heat exchangers and pressure piping. We currently maintain "U", "R", and "S" Stamps as well as the "NB" stamp indicating our ability to register completed work for our customers.

Our welding and procedures are extremely advanced and will continue to include new technology as it becomes available.

A large portion of our business includes the manufacturing of prefabricated piping assemblies, launchers/receivers, and valve settings. From general assembly drawings, we create isometric drawings, procure materials, fabricate the piping assemblies, x-ray, inspect, hydrostatic test, blast, and coat to meet the needs of our customers.
