SS welded tubes grade 317 Diameter 6.3 mm X 0.5 mm thickness ,Suppliers & Exporters in India.
Stainless steel (SS) welded tubes are a vital component in various industries where high-quality, reliable materials are essential for operation. But what makes SS welded tubes stand out? Seamless tubes are manufactured without any welded joints, offering enhanced strength and durability compared to welded tubes. This makes them a go-to choose for industries such as chemical processing, oil and gas, and food and beverage, where reliability and high performance are non-negotiable.
Welded tubes, especially those made from stainless steel, are also known for their resistance to corrosion and ability to withstand extreme temperatures and pressures. Today, we'll dive into one specific product: SS seamless tubes grade 317 with a diameter of 6.3mm and a thickness of 0.5mm. But first, let’s explore what makes Grade 317 stainless steel special.

Overview of SS Welded Tubes Grade 317
Grade 317 stainless steel is an austenitic alloy that offers superior corrosion resistance, particularly against acids and chlorides. This feature makes it suitable for applications in harsh environments, especially in chemical and petrochemical industries. Due to the higher molybdenum content, Grade 317 provides better protection against pitting and crevice corrosion than other stainless steel grades like 304 or 316.
Key Features of Grade 317 Stainless Steel
- High Corrosion Resistance: Excellent performance in environments with corrosive chemicals.
- High-Temperature Resistance: Suitable for applications exposed to extreme heat.
- Good Mechanical Properties: Maintains strength even at elevated temperatures.
Applications of SS Welded Tubes Grade 317
Industries like chemical processing, oil refineries, and pulp and paper production frequently use SS seamless tubes made from Grade 317 due to their superior resistance to corrosion and high durability. These tubes can also be found in marine applications and high-pressure systems, where robust materials are crucial for safety and efficiency.
The Role of Diameter in SS Seamless Tubes
The diameter of a tube plays a critical role in determining its application. Whether you are looking for tubes to transport fluids, gases, or other materials, the right diameter ensures smooth and efficient operations. In industrial settings, smaller diameters are typically used in instrumentation or for precise fluid control, while larger diameters may handle higher flow rates.
Specifics of 6.3mm Diameter SS Welded Tubes
SS seamless tubes with a 6.3mm diameter are particularly useful in industries where precision is key. Their compact size makes them ideal for controlled environments, such as:
- Instrumentation tubing: : For accurate measurements and fluid transport in chemical processing plants.
- Hydraulic systems: Small-diameter tubes are essential for delivering precise hydraulic pressure in machinery.
- Medical devices: These tubes can be used in specialized medical equipment requiring high purity and corrosion resistance.
Understanding Wall Thickness in SS Welded Tubes
The thickness of a welded 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.
0.5mm Thickness in SS Welded Tubes
The 0.5mm wall thickness offers a balance between strength and flexibility, making it suitable for applications that require lightweight tubing without compromising durability. Industries where weight is a critical factor—such as aerospace, medical devices, or smaller hydraulic systems—often prefer this thickness.
Benefits of 0.5mm Wall Thickness
- Lightweight:Reduces the overall weight of equipment and systems.
- Precision:Ideal for fine applications requiring delicate handling of fluids or gases.
- Corrosion Resistance: Thinner tubes made from Grade 317 still maintain excellent resistance to corrosion, ensuring longevity in tough environments.
Manufacturing Process of SS Welded Tubes Grade 317
The production of SS welded tubes involves complex processes to ensure their high quality. Here’s a brief overview of how these tubes are manufactured:
- Billet Selection: Stainless steel billets are chosen for their quality and properties.
- Hot Extrusion: The billet is heated and extruded into a tubular form.
- Cold Drawing: The tube is further processed to achieve the precise diameter and thickness.
- Heat Treatment: The tubes are treated to enhance their mechanical properties.
- Finishing: Finally, tubes undergo surface treatment and are tested to ensure they meet industry standards.
Quality Control in SS Welded Tube Manufacturing
Manufacturers apply stringent quality control measures, including non-destructive testing (NDT), to guarantee that each tube can withstand the conditions it is designed for. Common tests include ultrasonic testing, eddy current testing, and hydrostatic pressure testing.
Advantages of SS Welded Tubes Grade 317
Corrosion Resistance
Grade 317 is particularly renowned for its corrosion resistance in harsh chemical environments, making it ideal for chemical processing and pharmaceutical industries.
High Temperature and Pressure Resistance
These tubes can withstand high temperatures and pressures, which makes them a reliable choice for heat exchangers and boilers.
Longevity and Durability
With proper maintenance, Grade 317 seamless tubes offer a long service life, reducing the need for frequent replacements, thus cutting down on operational costs.
Applications of 6.3mm X 0.5mm SS Welded Tubes in Specific Industries
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.
