GAOLIN TECH Ultra-High Purity (UHP) Stainless Steel EP Tubing

1. Product Introduction

At GAOLIN TECH, we specialize in the production of premium Electropolished (EP) stainless steel tubing engineered for the most demanding high-purity environments. Our EP tubes undergo a specialized electrochemical process that removes surface impurities and levels out microscopic peaks, resulting in a mirror-like, ultra-smooth internal finish. This process is essential for preventing particle entrapment and ensuring the integrity of ultra-pure gas and fluid delivery systems.

2. Premium Materials & Superior Performance

Our EP tubing is manufactured from high-quality vacuum-melted raw materials to ensure maximum purity:

● Grade 316L (Primary): The preferred choice for UHP applications due to its low carbon content and superior resistance to pitting and corrosion.

● Grade 304L: Available for applications requiring excellent weldability and durability in less aggressive environments.

● Surface Finish: Internal roughness is strictly controlled to Ra< 0.13μ or Ra< 0.25μ based on customer requirements.

3. Stringent Quality Control

GAOLIN TECH maintains a "Zero-Defect" philosophy. Every inch of our EP tubing is subjected to a rigorous inspection protocol:

● 18.2MΩ·cm Ultrapure Water Cleaning: Conducted in ISO Class 4 (Class 10) cleanrooms to ensure the highest level of cleanliness.

● Precision Inspection: 100% scanning for surface defects using advanced profilometers and borescope technology.

● Strict Packaging: Each tube is purged with high-purity Nitrogen (N2), capped, and double-bagged in specialized polyethylene film to prevent contamination during transit.

4. Ready-to-Ship Inventory (100,000+ Feet in Stock)

To support your project timelines, we maintain a massive ready-to-ship inventory of over 100,000 feet of standard UHP EP tubing.

5. Technical Specifications
