FAQ – Orbital Welding Piping Solutions
What is orbital welding?
Orbital welding is a high-precision welding process where the welding electrode rotates around the pipe, creating consistent, contamination-free welds ideal for high-purity piping systems in critical applications.
What industries benefit from orbital welding solutions?
Industries like pharmaceuticals, semiconductors, food & beverage, and specialty chemicals require orbital welding to maintain high-purity standards in their piping systems for water, steam, and chemical transfer.
Why is orbital welding important for high-purity applications?
Orbital welding ensures contamination-free, repeatable welds, which are essential for high-purity applications in industries that require strict hygiene standards and leak-free piping systems.
What materials are used in orbital welding systems?
We use SS 316L, electropolished tubes, ASME BPE-compliant materials, and PTFE-lined sections for specialized piping systems to ensure maximum purity and corrosion resistance.
How do you ensure quality and compliance in orbital welding?
We conduct visual inspections, borescope inspections, helium leak testing, and provide complete weld traceability documentation to ensure that our orbital welding systems meet global quality standards and industry regulations.
