SS welded tubes grade 347 Diameter 15.8mm X 1.2 mm thickness
The full detail for this product as supplied from our Mumbai stockyard: sizes, grades, standards, tolerances, tests and applications.
SS Welded tubes grade 347 Diameter 15.8mm X 1.2 mm thickness, Suppliers & Exporters in India.
Stainless Steel Welded Tubes are widely used in industries that demand high resistance to corrosion and heat. Among the many grades, SS 347 (UNS S34700) stands out for its exceptional resistance to intergranular corrosion, especially after exposure to temperatures that result in chromium carbide precipitation (around 800-1500°F or 425-815°C). The addition of niobium (columbium) stabilizes this austenitic steel, making it ideal for high-temperature applications.

Why Choose SS 347 Welded Tubes?
- Superior Corrosion Resistance:SS 347 is more resistant to corrosion in high-temperature environments compared to other austenitic steels. It excels in environments with sulfuric, nitric, and phosphoric acids.
- High-Temperature Stability: SS 347 tubes can be used in continuous service at temperatures up to 1500°F (816°C), making them ideal for furnace parts, heat exchangers, and aircraft exhaust manifolds.
- Weldability & Durability: These tubes exhibit good weldability and can handle high stress, making them suitable for industries such as petrochemical, power generation, and aerospace.
Specifications of SS Welded Tube: Diameter 15.8mm X 1.2mm Thickness
For specialized applications, precision dimensions play a critical role. The SS Seamless Tube Grade 347 with a 15.8mm diameter and 1.2mm wall thickness is perfect for industries that require tubes with high mechanical strength, dimensional accuracy, and corrosion resistance.
Dimensions and Specifications:
- Outer Diameter: 15.8mm
- Wall Thickness: 1.2mm
- Material Grade: SS 347
- Length: Customizable according to project requirements
- Standards:ASTM A312, ASTM A213, or as per customer specifications
Applications of SS 347 Welded Tubes
Due to its excellent properties, SS 347 seamless tubes with a 15.8mm diameter and 1.2mm thickness are suitable for a wide range of applications:
- Heat Exchangers: The high-temperature stability of SS 347 makes it ideal for use in heat exchangers that operate at elevated temperatures.
- Chemical Processing Equipment: The superior resistance to acid attacks, especially in harsh environments like sulfuric or nitric acid processing.
- Aerospace and Aircraft ComponentsUsed in aircraft exhaust manifolds and other high-temperature components due to its thermal stability and corrosion resistance.
- Pharmaceutical and Food Processing: The hygienic nature of stainless steel, coupled with its high resistance to corrosion, makes it ideal for manufacturing equipment in these sectors.
Benefits of Seamless Tubes Over Welded Tubes
While both seamless and welded tubes are available in SS 347, seamless tubes offer several advantages:
- Uniformity of Structure: Seamless tubes do not have a weld seam, which makes them structurally stronger and more reliable in high-pressure applications.
- Enhanced Durability:Due to the absence of a weld seam, seamless tubes have a higher resistance to corrosion and oxidation.
- Precision in Manufacturing:: Seamless tubes offer superior dimensional accuracy, crucial for applications that demand exact tolerances.
