High Purity Gas Distribution System with Orbital Welding Technology
High Purity Gas Distribution System with Orbital Welding Technology
Orbital Welding is a specialized welding process where the welding arc is rotated mechanically around a fixed workpiece, such as a pipe or tube. This method ensures a high degree of precision, uniformity, and consistency, making it ideal for applications requiring high-quality welds, especially in industries like aerospace, pharmaceuticals, semiconductors, and healthcare.
Key Features of Orbital Welding:
- Automated Process: Controlled by a programmable system, reducing the chances of human error.
- High Purity: Produces clean, contaminant-free welds essential for handling high-purity gases and liquids.
- Consistency: Ensures uniform weld quality across multiple joints, even in challenging environments.
- Efficiency: Speeds up the welding process while maintaining superior quality.
- Non-Destructive Testing Compatible: Welds produced are typically compliant with rigorous testing standards.
Helium Leak Testing is a highly sensitive and reliable method used to detect leaks in systems or components. Helium is used as a tracer gas because of its small atomic size, inertness, and non-reactive nature, which allows it to escape through even the smallest leaks.
Testing Methods
- Vacuum Method:
- The system is placed under a vacuum.
- Helium is sprayed externally over potential leak areas.
- The detector inside the system identifies any helium that enters.
- Application: Common in sealed components like vacuum chambers.
- Pressure Method (Sniffing Test):
- Helium is pressurized inside the system.
- A sniffing probe detects any helium escaping from the system.
- Application: Suitable for pipelines, storage tanks, and other pressurized systems.
Advantages
- High Sensitivity: Detects leaks as small as 10⁻¹² mbar·l/s.
- Reliable and Repeatable: Provides consistent and precise results.
