SS welded tubes grade 347 Diameter 10.0mm X 1.2 mm thickness

SS welded tubes grade 347 Diameter 10.0mm X 1.2 mm thickness, Suppliers & Exporters in India.

A welded tube is essentially a hollow cylinder made from stainless steel, formed through a process that does not involve welding or joints. This lack of seams allows for a more uniform structure, which is essential for applications that demand high performance under pressure or exposure to corrosive environments.

What Is SS Welded Tubes?

Stainless steel (SS) seamless tubes are critical components used in various industries, known for their durability, precision, and ability to withstand harsh conditions. Unlike welded tubes, seamless tubes are manufactured without any joints, which significantly enhances their strength and resistance to pressure.

Stainless steel (SS) seamless tubes are a crucial component across various industries, from petrochemical plants to pharmaceuticals. These tubes, especially those made from stainless steel Grade 317, are known for their strength, durability, and resistance to corrosion. One specific variety—SS seamless tubes with a 9.5 mm diameter and 0.5 mm wall thickness—stands out for its versatility and specialized applications. But what makes these tubes so unique, and why are they an essential part of industrial processes?

Overview of Stainless Steel Grade 317

Grade 317 stainless steel is a high-alloy austenitic stainless steel that’s prized for its superior corrosion resistance compared to other stainless steel grades. Its composition includes chromium, nickel, and a higher percentage of molybdenum, which boosts its resistance to pitting, crevice corrosion, and general corrosion in hostile environments.

This makes Grade 317 particularly well-suited for chemical processing environments, where exposure to chlorides, acids, and other corrosive substances is common. The addition of molybdenum enhances its ability to withstand harsh environments and high temperatures, adding to its versatility.

Characteristics of SS Welded Tubes Grade 317

What sets Grade 317 SS welded tubes apart is their exceptional properties, including:

  • Corrosion Resistance:The high molybdenum content ensures excellent resistance to pitting and corrosion, even in chloride-rich environments.
  • High-Temperature Performance: Grade 317 can perform at high temperatures without losing its structural integrity, making it ideal for industries like chemical processing and marine applications.
  • Strength and Durability: This grade is known for its strength, both at room and elevated temperatures, which means it can handle pressure and force without deforming or weakening.

Applications of SS Welded Tubes Grade 317

SS welded tubes made from Grade 317 find applications in a variety of industries:

  • Chemical and Petrochemical Industry: Thanks to their high resistance to corrosive materials, Grade 317 tubes are widely used in the transportation and processing of chemicals.
  • Marine Environments:The enhanced corrosion resistance makes them ideal for use in seawater and coastal environments.
  • Pharmaceutical and Food Processing: The cleanliness, corrosion resistance, and durability of these tubes ensure they meet the strict sanitary requirements of these industries.

SS Welded Tubes of Diameter 9.5 mm: Specifications and Uses

The 9.5 mm diameter size offers specific advantages for certain applications. This size is compact enough for intricate systems while being robust enough to handle significant pressures. Tubes of this diameter are typically found in systems where space-saving and high-performance are required, such as in heat exchangers, fuel lines, and precision machinery components.

Manufacturing Process of SS Welded Tubes Grade 347

SS seamless tubes are made using two primary methods—hot rolling and cold rolling. Hot rolling involves heating the steel and forming it into the desired shape at high temperatures. Cold rolling, on the other hand, is done at room temperature and results in a smoother finish and more precise dimensions.

After the tubes are formed, they undergo rigorous quality control processes, including pressure testing, dimensional inspection, and non-destructive testing to ensure they meet stringent industrial standards.
