This tubing is manufactured without any seams or welds, ensuring a uniform structure and high strength. It is available in a range of sizes, typically from 1/8 inch to 4 inches in diameter. Known for its excellent corrosion resistance and durability in high-temperature applications.
Produced by welding flat sheets of stainless steel into a tube shape, this option is often more cost-effective than seamless tubing. It is available in sizes ranging from 1/4 inch to 8 inches in diameter. Offers good corrosion resistance and is suitable for less demanding environments.
Designed for use in heat exchangers, this tube type features enhanced thermal conductivity and resistance to thermal cycling. Commonly available in sizes from 1/2 inch to 2 inches in diameter. It provides good corrosion resistance and thermal stability.
Ideal for precise measurement and control applications, this tubing is available in small diameters, typically from 1/16 inch to 1 inch. It offers high corrosion resistance and maintains integrity under high pressure and temperature conditions.
Used in boilers for transporting steam and other fluids, these tubes are available in sizes from 1 inch to 4 inches in diameter. They are highly resistant to oxidation and corrosion at elevated temperatures.
Shaped in a U-form, these tubes are used in applications where a flexible connection is needed, often in heat exchangers. They come in sizes from 1/2 inch to 2 inches in diameter. Known for their resistance to corrosion and ability to handle thermal expansion.
This tube type is used in condensers for heat exchange processes, typically available in sizes ranging from 1/2 inch to 2 inches in diameter. It offers high resistance to corrosion and fouling in challenging environments.
Equipped with fins to enhance heat transfer efficiency, these tubes are available in various sizes, commonly from 1 inch to 3 inches in diameter. They offer good corrosion resistance and are used in applications requiring efficient heat dissipation.
Stainless Steel 439 tubing has wide applications since it exhibits outstanding properties of high resistance to corrosion and heat. It is applied in the automotive exhaust system as it owes an excellent resistance to oxidation and high-temperature processes involved in the exhaust system. This tube is also used in hostile environments in heat exchangers, condensers, and other industrial equipment. SS 439 is also used for medical equipment, boilers and water treatment plants because it has strength and hardness with scaling and corrosion resistance
