Trusted by global industry leaders
Experts in our industry
For more than 65 years we have developed and refined custom fabrication technology and procedures. Our team brings deep experience across engineering, quality control, estimating, drafting, document control, welding, fitting, bending, cutting, and rolling - hundreds of years of combined know-how on the shop floor and in the field.
Qualifications
We maintain over 1,600+ ASME Section IX qualified welding procedures used every day to build high-quality vessels. We fabricate with a wide range of materials - stainless steel, carbon steel, aluminum, INCONEL® alloys, Hastelloy®, duplex stainless, chrome-moly, MONEL® alloys, nickel, and more.
Engineering & Fabrication
01 - HEAVY ENGINEERING
In-House 3D Design
ASME VIII-1 and VIII-2 certified fabrication, designed by our own engineers. They model the job in 3D, know the shop that will build it, and stay with the work from the first drawing through fit-up, so questions get answered by the people who designed it.
02 - PRECISION EXECUTION
Advanced Welding
Mastery of FCAW, SAW, GMAW, GTAW, and Pulse MIG on exotic alloys and high-pressure carbon steel. Pulse-arc technology for zero-defect joins.
03 - PRODUCTION SCALE
Turnkey Vessels
Turnkey fabrication of massive vessels ready for immediate service. We provide full-scale shop fit-up including tray installation, industrial painting, and insulation.
04 - VERIFICATION
NDT & Quality
X-Ray, Hydrostatic, and Ultrasonic testing. 100% compliance with API/ASME global standards.
Featured Case Study
