CJan Ultra-Clean Metal Welding Fittings UCFS

The UCFS Series fittings are designed for the delivery of ultra-clean gases (specialty gases) and are widely used in industries such as semiconductor manufacturing, solar energy, nuclear energy, LED, TFT-LCD, petrochemicals, and biopharmaceutical production. These fittings can be safely connected using automatic or manual welding techniques, and even in ultra-compact spaces, mini micro-welding options are available. Depending on process requirements, we offer both BA-grade and EP-grade finishes.

Features of UCFS Series Fittings:

1. Ultra-Clean: Standard surface polishing on tubes and fitting bodies achieves an average roughness of Ra 10 µin (0.25 µm) and Ra 5 µin (0.13 µm).

2. Residue-Free: Smooth transitions in the flow path ensure stable fluid flow.

3. Precision Welding Ports: Straight, sharp-edged, and burr-free welding ports with uniform and precise wall thickness, improving welding repeatability.

4. Comprehensive Sizes: A wide range of sizes to meet spatial requirements, with custom options available.

5. Versatile Welding: Suitable for both manual and automatic welding applications.

Applications:

• Semiconductor manufacturing (specialty gas delivery)

• Solar and nuclear energy systems

• LED and TFT-LCD production

• Petrochemical and biopharmaceutical industries

Surface Finish Options:

• BA Grade: Ra ≤ 10 µin (0.25 µm)

• EP Grade: Ra ≤ 5 µin (0.13 µm)

Advantages:

• Ensures contamination-free gas delivery in critical processes.

• Compatible with tight spaces and complex layouts.

• High repeatability and reliability in welding applications.
