About Mountaineer Fabricators Inc
Mountaineer Fabricators Inc was founded in 1923 as a family-owned fabrication business. In 2004, the company was acquired and moved into a newly constructed facility in Nitro, West Virginia, where it operates today. The company designs and manufactures ASME-code pressure vessels, pre-fabricated piping assemblies, and modular skidded process units. Its in-house shop provides plate rolling, engine lathe turning, horizontal and vertical boring, CNC milling and drilling, surface grinding, and a full suite of pressure testing including hydrostatic, pneumatic, helium leak detection, and nitrogen sensitive leak methods. Welders are qualified to ASME Section IX and API-1104, and the engineering department performs ASME Section VIII Division 1 design calculations using Compress software alongside AutoCAD drafting. The facility handles piping diameters from 1/4 inch to 120 inches and maintains ASME U, R, S, and NB stamps for fabrication and repair. Mountaineer Fabricators serves the oil and gas, power generation, chemical processing, and natural gas industries, as well as air separation, steam piping, oxygen and nitrogen production, heat exchanger, glass wool, data center, food processing, and Kevlar-related sectors. Its prefabricated piping assemblies, launchers and receivers, and valve settings are used to reduce field construction costs for customers in those markets. It emphasizes the combination of modern equipment and a tenured, cross-trained team to achieve extreme precision across diverse industries.
