Nearly four decades of building complex, high-spec equipment for the people who run the world’s energy and process industries.
Founded in 1986, Custom Heliarc grew up in API 618 reciprocating compression. Over nearly forty years we’ve become a main vessel and packaging facility for OEMs — fabricating ASME Section VIII vessels and complete compression packages for the oil, gas, petrochemical, and industrial-gas industries.
We’re ASME “U” and National Board “R” authorized and a major supplier of midstream ASME VIII vessels — from separators and pulsation dampeners to specialty cryogenic and medical reactor vessels. We’ve also built deep experience in hydrogen equipment as the energy transition accelerates.
We stay deliberately nimble. We understand complex, high-spec systems, help identify issues before they happen, and deliver the designed solution that meets your needs — on time, on spec, on budget.
We do what is specified — not what’s convenient. Your codes, line classes, and acceptance criteria are the standard we build to.
We develop and maintain long-term client relationships — many measured in decades, not jobs.
We don’t over-commit. We won’t waste your time or take work we can’t do right.
