One shop for pressure vessels, reciprocating compression packages, and the auxiliary systems and piping that complete them.
ASME “U” StampAs an ASME “U” and National Board “R” authorized shop, we fabricate code vessels for some of the most demanding service in the industry — and we’re a major supplier of midstream ASME VIII vessels.
API 618Custom Heliarc grew up in API 618 reciprocating compression and has packaged multi-medium compression units for the oil, gas, and petrochemical industries on six continents — for destinations from the Gulf Coast to Saudi Arabia, Mexico, Canada, South Africa, and Thailand.
API 614 / 618We have fabricated and performed run & cleanliness testing to API 614 and API 618 standards since 1995. With a combined 70 years of piping and structural fabrication experience — including 35 years in console packaging, testing, and troubleshooting — our consoles are in service from Pocatello, Idaho to Map Ta Phut, Thailand.
H₂Custom Heliarc has extensive experience fabricating hydrogen equipment, including high-pressure hydrogen diaphragm compressor packages — supporting clients like Plug Power, Air Products, Air Liquide, and Linde as the industry scales H₂ infrastructure.
ASME B31We fabricate loose piping to ASME B31 codes and API 1104, including interconnect piping spools for field installation of modular units at project sites.
TIGThe heliarc (TIG) process is the most versatile welding process ever invented — and it’s in our name. With 35+ years of experience, the range of materials we can weld is virtually endless.
