Hire the Best GASWorkS Specialists

I help engineering teams and technical clients solve mechanical and piping-related problems through pipe stress analysis, FEA, piping support evaluation, and fabrication-ready CAD documentation. My strongest background is in industrial piping systems, including CAESAR II pipe stress analysis, ASME B31.3 piping design, flexibility evaluation, support loads, flange checks, vibration awareness, and practical layout/support decisions. Main services: - Pipe stress analysis using CAESAR II - Piping flexibility and support load evaluation - Piping support design, redesign, and structural verification - Flange leakage / load checks - Mechanical and structural FEA - Fabrication-ready 3D CAD models - Manufacturing drawings, spool drawings, BOMs, DWG/DXF/PDF packages - Reverse engineering from 3D scans, photos, sketches, or existing parts I work with a practical engineering mindset: the final result must not only look correct in CAD, but also be buildable, installable, maintainable, and technically justified. My experience includes industrial piping systems, pipe supports, mechanical structures, lifting-related components, vibration-sensitive systems, and manufacturing documentation. If you need someone who can understand the engineering problem, evaluate the constraints, and deliver a clean technical solution, I can help.
