Nickel 20 Capillary Tubes are specialized tubular products made from high-purity Nickel Alloy 20, engineered for precise applications where resistance to corrosion, pressure, and high temperatures is critical. These tubes are characterized by their ultra-small outer diameters and thin wall thickness, making them ideal for micro-scale fluid flow systems and heat exchange mechanisms. Their superior resistance to sulfuric acid and chloride-induced corrosion makes them highly effective in aggressive chemical processing environments.
Manufactured by Sumer Metal Industries Private Limited, these tubes are produced using advanced cold-drawing techniques that ensure dimensional accuracy and surface finish. Sumer Metal is recognized for its stringent quality standards, in-house testing facilities, and adherence to international specifications like ASTM B729 and B464. With a commitment to engineering excellence, the company caters to a wide range of industries, including pharmaceuticals, chemical processing, power generation, and aerospace instrumentation.
One of the key advantages of Nickel 20 Capillary Tubes is their versatility in high-precision applications. These include chromatography systems, thermocouples, hydraulic control lines, and nuclear reactors—where even minor material failure can cause critical damage. The alloy’s low carbon content and stabilized austenitic structure enhance weldability and minimize carbide precipitation, thereby increasing service life and performance reliability.
Sumer Metal Industries ensures that each batch of capillary tubes is subjected to rigorous quality control, including hydrostatic testing, eddy current testing, and dimensional verification. The tubes are available in both seamless and welded formats, with custom sizing available on request. Their production process guarantees smooth internal surfaces that minimize friction and fluid resistance, a crucial factor in maintaining accuracy in flow-based systems.
