Orbital Tube Welding Purge Kit
$3,800.00
An orbital tube welding purge kit is a specialized system designed to create and maintain a controlled atmosphere inside tubing during orbital welding. It works by displacing ambient air with an inert gas—most commonly high-purity argon—inside the tube or pipe, ensuring that the weld zone remains free of oxygen, moisture, and other contaminants that can compromise weld quality.
OWETEC standard purge kit includes:
- 1/8” - 1’ size straight and tee SS 316L Tube Fittings that seal both sides of the weld zone.
- Gas inlet and exhaust lines with SS 316L Purge Pins to introduce and regulate purge gas flow.
- Monitoring equipment such as Magnahelic guage.
- Flexible tubing and fittings for easy setup across different tube sizes.

Importance of an Orbital Tube Welding Purge Kit
The purge kit is critical for ensuring clean, defect-free welds in industries where weld integrity is non-negotiable, such as semiconductor, aerospace, pharmaceutical, nuclear, and food & beverage. Its importance includes:
In short: An orbital tube welding purge kit is not just an accessory—it’s a requirement for achieving high-purity, high-integrity welds in critical applications.

PRODUCT INFO
1. Oxidation Prevention
• Without purging, molten weld metal reacts with oxygen and nitrogen, causing discoloration, porosity, and reduced corrosion resistance.
2. Enhanced Weld Quality & Mechanical Properties
• A proper purge ensures smooth, strong welds with minimal inclusions or contamination.
3. Compliance with Industry Standards
• Many codes and customer requirements mandate controlled purge levels (e.g., ASME BPE, AWS D18, SEMI standards).
4. Repeatability & Reliability
• Especially in orbital welding, where consistency is the goal, a purge kit guarantees stable conditions across every weld.
5. Cost Savings
• Prevents rework, scrap, or premature failures due to poor weld quality.
