The Mid-Level Mechanical Fitter – Pressure Systems is responsible for the assembly, installation, and maintenance of pressure piping, tanks, and associated mechanical systems. This role ensures equipment operates safely and reliably in compliance with industry standards, particularly in hygienic and regulated environments. The fitter works independently on routine tasks and supports complex system overhauls or installations under senior supervision.
Install and modify pressure-rated piping, valves, regulators, and stainless steel fittings.
Fit and align mechanical components in accordance with ASME, 3-A, or EHEDG standards.
Perform sanitary and hygienic installations using orbital weld prep or clamp-type fittings.
Inspect and maintain pressure vessels, steam lines, condensate systems, and expansion loops.
Replace seals, gaskets, and fittings as needed to prevent leaks or contamination.
Troubleshoot mechanical issues in pumps, heat exchangers, valves, and compressed air systems.
Assist in hydrostatic and pneumatic pressure testing under controlled conditions.
Support documentation of inspections, repairs, and maintenance records in CMMS.
Follow safety protocols related to pressure systems, including confined space and lockout/tagout.
Interpret and work from P&IDs, mechanical drawings, and layout diagrams.
Collaborate with welders, pipefitters, and engineers to complete installations and shutdown work.
Train junior fitters on safety practices, tool usage, and system layouts.
