Product Description

 

Product Description

Nai-Lok's ultra-high-purity (UHP) seamless stainless steel tubes are manufactured from premium ASTM A269 TP316L stainless steel, designed for critical applications in semiconductor, biopharmaceutical, and food processing industries. This product features an outer diameter of 101.6 mm and a wall thickness of 2.11 mm, processed with bright annealing (BA) or electropolishing (EP) to ensure ultra-low particle generation and superior corrosion resistance, making it ideal for high-purity fluid delivery systems.

Key Features

 Material Certification: Compliant with ASTM A269 TP316L, low carbon content (≤0.03%) for excellent intergranular corrosion resistance.
 Ultra-High Cleanliness: Inner surface Ra ≤ 0.25 µm (EP) minimizes particle adhesion, meeting SEMI, ASME BPE, and ISO standards.
 Superior Corrosion Resistance: High Cr (16-18%), Ni (10-14%), and Mo (2-3%) content enhances resistance to pitting and crevice corrosion.
 Precision Dimensions: OD 101.6 mm (±0.1 mm), WT 2.11 mm (±5%) for leak-proof sealing and optimal fluid flow.
 Custom Finishing: Available in bright annealed (BA) or electropolished (EP) for varying cleanliness requirements.

In addition to 316L stainless steel, Nai-Lok manufactures ultra-clean tubes in:

• Hastelloy® C-22/C-276: For extreme corrosion resistance in acidic/chloride-rich semiconductor processes.

• Inconel® 600/625: High-temperature stability for CVD, diffusion furnaces, and etch systems.

  Product Parameters

  Manufacturing procedure:

Billet→Inspection→Peeling→Cutting→Punching (Certering)→Heating→Piercing→Inspection→Lubricating and drying→Cold drawing /
Rolling→Degreasing→Solution annealing→Straightening→Cutting→Pickling / Passivating→Final inspection→Marking→Packing→Shipping

1. Material Selection: Vacuum-melted 316L stainless steel with ultra-low sulfur and phosphorus content.

2. Cold Drawing: Ensures dimensional accuracy and smooth surface finish.

3. Bright Annealing (BA): Oxygen-free annealing prevents oxidation, maintaining a clean metallic surface.

4. Electropolishing (EP) (Optional): Further reduces surface roughness and enhances corrosion resistance.

5. Strict Inspection: Includes eddy current testing (ET), hydrostatic testing, and borescope inspection for defect-free quality.
