← Fabrication / The Highest Standards in Fabrication
Power, Petro-Chemical and Refining
Pre-fabrication in power plants requires x-ray quality welds per ASME Section 9 Standards. Materials used include traditional carbon steel, various grades of chrome, and other alloy piping materials. Wall thicknesses can range from standard Schedule 40 up to several inches. Welding these pipe joints takes strict adherence to specific welding procedures and quality control measures. In many cases, this includes the use of automatic welding processes such as sub-arc or roto weld. Contractors and owners have come to appreciate the advantages of performing this work in a fabrication shop setting because of enhanced safety, quality control, budgets, and ready access to advanced technology. The United Association has thousands of skilled tradespeople working in these fabrication shops all across North America.
Process piping can be found in a variety of specialized manufacturing settings, from food processing to pharmaceutical and biotech plants to industrial processes such as petro-chemical plants and refineries. These systems supply a variety of materials—natural gas, liquids, steam, air, refrigerants, chemicals and more, often under high pressure and in sensitive environments. These systems are designed and built in fabrication shops with some of our strongest contractor partners. Through the successful relationship established with fabrication shop owners, UA local unions have increased work in the fabrication and modularization sector, and have developed proven efficiencies, quality procedures and productivity that owners and end users have come to rely on.
Commercial and Institutional
Fabrication and modularization work is found increasingly on projects such as hospitals and health care facilities, office buildings, schools and dormitories, and prisons. These systems include everything from plumbing systems to HVACR to medical gas systems. These systems are fabricated offsite, in a controlled environment and according to strict codes and standards. The second step in the fabrication process is when the systems are installed, tested and put into operation on the jobsite, but every step along the way the highest standards of quality are followed to protect the integrity of every project.
