Stainless Steel Capillary Tube is a type of pipe made from stainless steel, which is a corrosion-resistant metal alloy containing at least 10.5% chromium. The chromium forms a protective layer on the surface of the steel, preventing rust and other types of corrosion from occurring. Stainless steel pipes are commonly used in various industrial applications, such as oil and gas, food and beverage, pharmaceuticals, and chemical processing, as well as in residential and commercial plumbing systems. They are also popular as decorative features in architectural and interior design. Stainless steel pipes come in different grades, sizes, and shapes, with the most common being round, square, and rectangular. They can also be welded or seamless, depending on the intended use and application.
