Hastelloy C-22 Capillary Tube (UNS N06022 / W.Nr. 2.4602)
High-strength corrosion-resistant alloy Capillary Tube for chemical petrochemical processing and pollution control
As a leading Chinese supplier of high-performance nickel alloys, SEATHER TECHNOLOGY manufactures precision-engineered Hastelloy C-22 (UNS N06022) capillary tubes designed for demanding applications requiring exceptional corrosion resistance and tight dimensional control.
Hastelloy C-22 has excellent strength and corrosion resistance. It can also perform well under high temperature and pressure. Hastelloy C-22 round tube can be widely used in chemical, pharmaceutical, marine, aerospace and other fields. Its high strength and excellent corrosion resistance make it stable in extreme environments.
Hastelloy C-22 capillary tubes are specialized alloy tubes featuring small diameters, thin walls, and higher processing difficulty. They are manufactured from precision-drawn C-22 coil tubing, then straightened and polished to achieve superior dimensional accuracy and a clean internal surface. These tubes are ideal for applications requiring both high corrosion resistance and strict control of internal geometry.
We offer both seamless and welded Hastelloy C-22 capillary tubes to suit different application needs. During the polishing process, surface finishes such as MP (Mechanical Polish), EP (Electropolish), BA (Bright Annealed), AP (Acid Pickled) and more can be customized upon request.
The capillary tubes we produce feature a refined surface appearance, tight dimensional tolerances, and stable mechanical properties, ensuring reliable performance in critical systems such as instrumentation, chemical sampling, precision flow control, and miniaturized components.
For high-quality Hastelloy C-22 capillary tubes with full customization options, SEATHER TECHNOLOGY is your trusted manufacturing partner.

More Information About Hastelloy C-22 Capillary Tube (UNS N06022)
When you choose to buy Hastelloy C-22 Capillary Tube (UNS N06022), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Hastelloy C-22 Capillary Tube (UNS N06022)
Hastelloy C-22 PREN: 46
The pitting resistance equivalency number uses the alloy’s chemical makeup to guess its power against pitting corrosion. You check how much chromium, molybdenum, tungsten, and nitrogen are in the alloy. These elements help keep the steel safe. The most used formula is:
PREN = CR% + 3.3 x (MO% + 0.5 x W%) + 16 x N%How to Purchase Hastelloy C-22 Capillary Tube (UNS N06022)
