Our UHP-Grade Tubing Products and Specifications
HYG Benelux offers a comprehensive range of UHP products designed for critical applications where purity is paramount. Our tubing is engineered to prevent contamination and ensure the integrity of your semiconductor process gas tubing systems.
UHP 316L Stainless Steel Tubing (Seamless & Welded)
Our flagship product is the UHP 316L stainless steel tubing, available in both seamless and welded forms. This material is chosen for its excellent corrosion resistance and stability. We offer restricted sulfur 316L tubing (0.005 – 0.015%) for enhanced weldability, making it perfect for orbital welding.
Key Specifications:
- Materials: 316L single melt, 316L double melt (optional), EN 1.4404.
- Applicable Norms: ASTM A269, A632, ASME SA213, JIS G3459.
- Surface Finishes: We provide exceptionally smooth internal surfaces to minimise particle generation and entrapment.
- Electropolished (EP) Finish (SF4): Achieves a surface roughness (Ra) of less than 0.25μm (10 Ra µ-inch). Our SF4 surface finish is ideal for the most critical UHP applications.
- Bright Annealed (BA) Finish: A high quality, smooth finish suitable for a wide range of high purity uses.
- Sizes: Available in imperial sizes from OD 0.125” to 6”.
Advanced Cleaning and Packaging
To maintain purity from our facility to yours, all our UHP tubing undergoes a meticulous cleaning and packaging process.
- Precision cleaned using warm, ultra pure supersonic immersion.
- Purged with heated and filtered nitrogen gas (99.9998% purity).
- Packaged in a Class 100 cleanroom.
- Individually end capped and double PE sleeved to prevent any contamination during transit.
This entire process ensures our tubing is orbital weld ready and can be integrated into your systems immediately. Explore our full range of Ultra-High Purity products for more details.

Testing and Verification for Total Confidence
We provide complete assurance through rigorous testing procedures. Our in-house R&D centre is equipped to perform a wide variety of tests to verify the integrity and performance of our tubing.
- Helium Leak Tested Tubing: We conduct helium leak tests to guarantee the integrity of our tubes, a critical requirement for containing high purity gases.
- Particle and Residue Testing: Each batch is tested for particles and oil residue to confirm it meets UHP standards.
- Intergranular Corrosion Testing: Performed according to ASTM A262 Practice E to ensure long term material stability.
- Boroscope Examination: Visual inspection of the internal surface to guarantee a flawless finish.
- Positive Material Identification (PMI): Verifies the alloy composition of every tube.
