High-strength corrosion-resistant alloy pipe Tubes for chemical processing and pollution control system
As a leading Incoloy supplier in China, SEATHER TECHNOLOGY manufactures and supplies high-precision Incoloy 825 capillary tubes for demanding industrial applications.
INCOLOY® alloy 825 (UNS N08825 / W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. Its carefully balanced chemical composition provides excellent resistance to a wide range of corrosive environments, including acidic and chloride-containing media. The high nickel content ensures strong resistance to chloride-ion stress-corrosion cracking.
Incoloy 825 capillary tube is a small-diameter alloy tube with high manufacturing difficulty and strict dimensional requirements. It is produced from Incoloy 825 coil tubing through straightening and precision polishing processes. These capillary tubes are ideal for applications that require high corrosion resistance, tight tolerances, and precise internal structures. According to different application needs, we can supply both seamless Incoloy 825 capillary tubes and welded Incoloy 825 capillary tubes. For surface treatment, MP, EP, BA, AP, and other finishing processes are available to meet various cleanliness and performance requirements. The capillary tubes produced by SEATHER feature excellent surface quality, strict dimensional control, and stable performance.

More Information About Incoloy 825 Capillary Tube (UNS N08825)
When you choose to buy Incoloy 825 Capillary Tube (UNS N08825), there have some important points we need to know before we get started.
Pitting resistance equivalency numbers (PREN) for Incoloy 825 Capillary Tube
Incoloy 825 PREN: 31.4
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 Incoloy 825 Capillary Tube
