Stainless Steel 304 Welded Capillary Tubes are made of high-quality miniature-sized tubing, which are used in applications where fluid flow performance, corrosion resistance, dimensional stability is required. Stainless Steel 304 Welded Capillary Tubes are made of AISI 304 / UNS S30400 stainless steel that contains high chromium (20%) and high nickel (10%).The high amount of these metals in the composition of the tubes makes them resistant to oxidation, along with their formability and weldability. Welded capillary tubes have OD ranging from 0.30 mm to 8.00 mm and have many applications like instrumentation, medical applications, chromatography systems, hydraulic control lines, and laboratory equipment that cannot be provided by conventional stainless steel tubing. USA Pipings is a trusted manufacturer and supplier of Stainless Steel 304 Welded Capillary Tubes that meet ASTM A269 specifications, with great surface finishes, customized dimensions, thorough quality control and reliable global availability.

Frequently Asked Questions
1. What are Stainless Steel 304 Welded Capillary Tubes?
Stainless Steel 304 Welded Capillary Tubes are precision small-diameter tubes made from Grade 304 stainless steel. They offer excellent corrosion resistance, dimensional accuracy, and reliable performance for industrial and instrumentation applications.
2. What is the difference between SS 304 welded and seamless capillary tubes?
SS 304 welded capillary tubes are manufactured by welding stainless steel strip, while seamless capillary tubes are produced without a weld seam. Seamless tubes are generally preferred for extremely high-pressure applications, whereas welded tubes are more cost-effective.
3. Why is SS 304 used for capillary tubes?
SS 304 is used because it provides excellent corrosion resistance, good weldability, high strength, and easy fabrication. It is also suitable for a wide range of industrial, medical, and laboratory applications.
4. Are SS 304 Welded Capillary Tubes corrosion resistant?
Yes. SS 304 Welded Capillary Tubes offer excellent resistance to corrosion, oxidation, and many chemicals, making them suitable for various industrial environments.
5. Can SS 304 Welded Capillary Tubes be used in food processing applications?
Yes. SS 304 Welded Capillary Tubes are widely used in food processing equipment because they offer excellent corrosion resistance, hygienic properties, and a smooth surface finish that supports easy cleaning.
