SS Welded tubes grade 317 Diameter 9.5mm X 0.5 mm thickness

SS welded tubes are a type of stainless steel tubing made without a weld joint. Unlike welded tubes, which are formed by welding strips of metal together, seamless tubes are manufactured by extruding a solid billet of metal, resulting in a continuous tube with no seams. This results in higher strength and resistance to stress, making seamless tubes ideal for demanding applications.

The key difference between seamless and welded tubes lies in their manufacturing process. Seamless tubes offer better performance, especially in high-pressure and high-temperature environments, where welded tubes might fail due to weaker weld joints.

Grade 317 stainless steel is an austenitic stainless steel known for its enhanced corrosion resistance. Its higher content of molybdenum (up to 3-4%) improves its resistance to pitting, crevice corrosion, and chloride-induced corrosion, making it superior to the commonly used Grade 316.

• Excellent resistance to corrosion in acidic and chloride-rich environments.
• High tensile strength and durability.
• Better performance at high temperatures compared to other grades.

Due to these properties, Grade 317 is used in industries that deal with aggressive environments, such as chemical processing, petrochemical, and marine industries

The thickness of a seamless tube's wall significantly impacts its strength, durability, and application. Thicker walls provide greater strength and are used in systems exposed to high pressure, while thinner walls, like 0.5mm thickness, are preferred for more lightweight or precision-based applications.

One of the main advantages of SS seamless tubes is their superior strength due to the absence of a weld seam. They perform better under extreme pressure and are less likely to suffer from localized weaknesses, which can occur in welded tubes. Furthermore, seamless tubes tend to have greater dimensional accuracy and are favored for critical applications where safety and reliability are paramount.

When we talk about Diameter 9.5mm x 0.5mm thickness, we're discussing very specific tube dimensions. Here’s why these measurements matter:

• Diameter 9.5mm: This small diameter makes the tube ideal for precision applications where space is limited, or for fluid transfer systems requiring narrow conduits.
• Thickness 0.5mm: The thin wall ensures lightweight performance without sacrificing strength, suitable for applications requiring high efficiency and reduced material usage.

This combination of diameter and thickness makes these tubes ideal for industries that require both precision and reliability, such as aerospace or medical equipment.

Grade 317 is particularly known for its excellent corrosion resistance. Thanks to its high molybdenum content, these tubes can withstand aggressive chemicals, including chlorides and acids, far better than standard stainless steels. This makes them ideal for applications like marine engineering and chemical processing, where exposure to corrosive environments is constant.

In addition to corrosion resistance, Grade 317 offers impressive mechanical properties:

• Tensile Strength: Around 515 MPa (75 ksi), making it strong enough to endure significant stress.
• Yield Strength: Approximately 205 MPa (30 ksi), which determines the tube’s ability to withstand permanent deformation.
• Hardness:This grade performs well even in environments where abrasion or physical impact is a concern.

These mechanical properties make it an excellent choice for heavy-duty applications, including heat exchangers and power plants.

Given its combination of properties, SS seamless tubes Grade 317 are used across a range of industries. Here are some key applications:

• Chemical Processing: Excellent resistance to acids and chlorides makes it ideal for equipment exposed to harsh chemicals.
• Marine and Offshore Industries:High resistance to saltwater corrosion ensures long-term performance in marine environments.
• Heat Exchangers: The tube’s mechanical properties and heat resistance make it perfect for heat transfer systems.

Chemical Processing

The resistance of Grade 317 to acids and chlorides makes these tubes a must-have in chemical processing plants where harsh environments is a given.

Food and Beverage Industry

Hygienic applications benefit from SS seamless tubes due to their corrosion resistance and ease of cleaning.

Oil and Gas Industry

The combination of high pressure and corrosive environments in the oil and gas sector makes Grade 317 tubes indispensable.
