Nuclear and Non-Nuclear Fabrication and Modular Construction

Nuclear/Non-Nuclear Fabrication and Modular Construction

HII Mechanical’s capabilities include the fabrication of tanks, pressure vessels, structural, shield panels and piping assemblies (pipe fabrication). Our capability ranges from individual components to fully outfitted equipment skids and complex modules. We have extensive experience working to AWS, ASME; nuclear and pressure vessel in government and military (DOD & DOE) requirements. We also maintain certificates of authorization from ASME and the National Board for fabrication, modifications, and repair including U, N, NB, NPT, NA, NS, R, VR and NR and are NQA-1 compliant.

Our products can be constructed from carbon steels, low alloy and high alloy steels, super alloys and other weldable material. Components and modules are fabricated at our main facility for easy shipping and transportation. Larger fabrications can be manufactured at our high bay facility or at the installation site. We incorporate photogrammetry and sophisticated dimensional control techniques such as laser scanning to verify compliance and simplify the installation process.

We offer our customers turnkey service with the capability for design, fabrication, testing, and installation. We excel on complex, one-of-a kind fabrications requiring stringent quality control.
