Nickel 20 Fin Tubes, 20 Nickel Fin Tube Manufacturer, Nickel 20 Fin Tube Supplier, Nickel 20 Fin Tube Exporter, Nickel 20 Precision Tubing, Nickel 20 Small Diameter Tube, Nickel 20 Fin Tubes
Nickel 20 Fin tubes are precision-engineered tubes made from commercially pure nickel (minimum 99.6% nickel content), designed for use in high-performance and highly corrosive environments. These tubes are widely used in Fin and control systems due to their excellent resistance to a variety of corrosive agents, especially in alkaline and reducing environments. Nickel 20's purity ensures consistent performance in applications that demand low magnetic properties and high conductivity.
One of the defining characteristics of Nickel 20 tubes is their outstanding corrosion resistance, particularly in environments containing caustic alkalis such as sodium hydroxide, potassium hydroxide, and other chemical processing media. This makes them ideal for use in industries such as chemical and petrochemical processing, pharmaceuticals, marine engineering, and food processing. In reducing environments, where materials like stainless steel may degrade more quickly, Nickel 20 maintains its integrity and durability.
These Fin tubes are typically manufactured as seamless to ensure a smooth, defect-free internal surface, which is crucial for precision control and measurement applications. They are produced to meet stringent standards such as ASTM B161 and ASTM B163, ensuring high quality and consistency. Common dimensions range from 1/8” to 2” outer diameter, with various wall thicknesses and custom lengths available to suit specific application needs.
Nickel 20 also offers excellent thermal and electrical conductivity, making it suitable not just for fluid or gas transport in Fin lines, but also for applications where electrical conductivity is required. It maintains its mechanical strength at elevated temperatures and is easily formable and weldable, allowing for flexibility in system design and fabrication.
