System Fabrication Services
Stainless Steel Fabrication
Principal Technology's welding department has extensive Stainless Steel piping and structural steel fabrication experience. Our welders are qualified to ASME XI and AWS D1.1 and 1.6.
get in touch
Stainless steel fabrication is often used for its corrosion and temperature resistance. Under the right circumstances, stainless steel can be the more cost-efficient solution when considering the post-fabrication surface prep and coating requirements for traditional carbon steel pipe and structural systems.
Our fabrication shop and welders are experienced with stainless steel handling, fabrication, and welding. Our shop personnel understand the importance of protecting stainless steel from cross-contamination with ferrous metals during all phases of the fabrication process.
With qualifications in ASME Section IX and AWS D1.1 and D1.6 using SS TIG and FCAW process, 6G positions, for piping to 24″ NPS, and metal thickness up to 3/4″, our welders are ready to tackle the most challenging SS and alloy fabrication projects.
