Introduction

Nickel 200 Pipe (also Nickel Alloy 200 Pipe, Alloy 200 Pipe, UNS N02200 Pipe, Pure Nickel Pipe, Commercially Pure Nickel Pipe) is a 99.6% minimum nickel alloy offering outstanding resistance to caustic alkalis and a wide range of corrosive environments. It conforms to ASTM B161 Nickel 200 Pipe (seamless), ASME SB161, ASTM B725 (welded), and ASTM B775 (welded tube). This commercially pure nickel material is designated UNS N02200 and meets Nickel Alloy 200 Specification.

Key properties of Nickel 200:

• Excellent alkali resistance – superior performance in caustic soda (NaOH), potassium hydroxide (KOH), and other strong alkalis

• Caustic corrosion resistant pipe – negligible corrosion rates in concentrated NaOH up to 350°C

• High thermal conductivity – approximately 70 W/m·K, ideal for heat exchanger service

• Excellent electrical conductivity – suitable for electronic and electrical applications

• High purity nickel alloy – minimizes contamination in food, pharmaceutical, and high‑purity chemical processes

• Low carbon nickel material – improves fabrication characteristics and avoids carbide precipitation

• Good fabrication properties – can be welded, brazed, soldered, and cold formed

This industrial nickel alloy pipe is available in seamless (ASTM B161) and welded (ASTM B725) forms, cold drawn, hot finished, pickled, or polished. We offer custom sizes, cut to length, large diameter, and thin wall options, with Schedule 40 and Schedule 80 schedules. Our product range includes Nickel 200 seamless pipe, welded pipe, large diameter pipe, custom size, and cut‑to‑length pipe.

Applications

1. Caustic Soda & Alkali Handling Systems

• Nickel 200 pipe for caustic soda service – piping for NaOH concentration, storage, and transfer in chlor‑alkali plants, alumina refining, and chemical manufacturing. Caustic corrosion resistant pipe outperforms carbon steel and stainless steel at elevated temperatures and concentrations.

• Nickel 200 pipe for alkali handling systems – piping for potassium hydroxide (KOH), sodium hydroxide, and other strong alkalis. Excellent alkali resistance eliminates pitting and caustic embrittlement.

• Alkali resistant nickel pipe – also used in rayon manufacturing, soap and detergent production, and metal cleaning lines.

2. Chemical Processing & Chlorine Production

• Nickel 200 pipe for chemical processing – reactor feed lines, heat exchanger tubes, and transfer piping for organic chemicals and high‑purity intermediates. High purity nickel alloy prevents product contamination.

• Nickel 200 pipe for chlorine production – piping in mercury cell and membrane cell chlorine plants, especially for wet chlorine service. Low carbon nickel material resists chlorine attack.

• Corrosion resistant pure nickel pipe – used in hydrochloric acid service (dilute, non‑aerated) and many reducing acid environments.

3. Food Processing & Pharmaceutical Industry

• Nickel 200 pipe for food processing equipment – milk processing lines, sugar refining evaporators, and edible oil handling. High thermal conductivity nickel provides efficient heat transfer and easy cleaning.

• Nickel 200 pipe for pharmaceutical industry – high‑purity water (WFI) distribution, API transfer lines, and clean steam systems. Excellent fabrication properties allow sanitary welding and polishing.

• Chemical process nickel pipe – also specified for biological processing equipment and fermentation vessels.

4. Heat Exchangers & Electronic Manufacturing

• Nickel 200 pipe for heat exchangers – shell‑and‑tube heat exchangers for caustic service, brine heaters, and condensers. High thermal conductivity nickel improves heat transfer efficiency.

• Nickel 200 pipe for electronic manufacturing – gas distribution lines for semiconductor fabrication, hydrogen lines, and high‑purity gas systems. Excellent electrical conductivity and non‑magnetic properties.

• High performance chemical process pipe – also used in synthetic fiber plants (rayon, nylon) and lithium battery chemical processing.

5. Chemical Storage Systems & High Purity Applications

• Nickel 200 pipe for chemical storage systems – tank outlet piping, vent lines, and recirculation loops for caustic storage tanks. Custom fabrication available for complex layouts.

• Nickel 200 pipe for high purity applications – semiconductor chemical delivery, ultra‑pure water systems, and specialty gas transfer. Pickled and polished interior surfaces ensure low particle generation.
