Precision Orbital Welding Piping Solutions for High-Purity Applications
Luthra Projects offers advanced orbital welding solutions for high-purity and critical process piping applications, where consistent, high-quality welds are essential. Our orbital welding systems ensure repeatable, contamination-free joints — meeting the highest standards of industries like pharmaceuticals, semiconductors, food & beverage, and specialty chemicals.
We provide complete turnkey execution — from system design and orbital welding planning to equipment mobilization, cleanroom-ready fabrication, and documentation as per global quality standards.
Scope of Work:
System Design & Weld Planning
Precise layout and isometric drawings with weld joint design and WPS (Welding Procedure Specification) suitable for orbital welding.
Material Supply & Weld Prep
Supply of high-purity piping materials, tubes, fittings, and surface-treated components (mechanical/electropolished) as per ASME BPE or similar standards.
Orbital Welding & Fabrication
In-situ and pre-fabricated orbital welding using closed-head or open-head orbital welders, executed by trained and certified welders.
Testing & Documentation
100% visual inspection, borescope inspection, helium leak testing, and full weld traceability documentation including weld logs, WPS, and PQR.
Cleanroom Compliance & Safety
Execution in cleanroom environments or contamination-controlled zones using validated procedures to ensure hygienic weld quality.
Applications Covered:
- Pharmaceutical Grade Utility Piping
- WFI (Water for Injection) & PW (Purified Water) Systems
- Clean Steam & Condensate Lines
- CIP/SIP (Clean-in-Place / Steam-in-Place) Circuits
- Semiconductor Grade Gas/Fluid Piping
- Food-Grade Hygienic Processing Lines
- Specialty Chemical Transfer Lines
Piping Materials & Options:
SS 316L (DIN 1.4435 / EN 1.4404) – Orbital-weld grade tubing for ultra-high purity applications.
Electropolished / Mechanical Polished Tubes – For superior internal surface finish and reduced biofilm formation.
