Stainless Steel 347 Seamless Pipes Manufacturer in India

Stainless Steel 347 Seamless Pipes are niobium-stabilized austenitic stainless steel pipes designed for applications requiring good corrosion resistance and reliable performance at elevated temperatures. The addition of niobium helps stabilize the material and reduces the risk of chromium carbide precipitation during prolonged exposure to elevated temperatures.

Manufactured without a longitudinal weld seam, Stainless Steel 347 Seamless Pipes provide uniform construction for demanding pressure and process piping systems. Their chromium, nickel and niobium alloy composition provides good oxidation resistance, strength, toughness and resistance to intergranular corrosion under suitable service conditions.

Stainless Steel 347 Seamless Pipes are used in heat exchangers, chemical processing equipment, petrochemical plants, power generation systems, thermal processing equipment and other industrial applications involving elevated temperatures. They are available in different outside diameters, wall thicknesses, schedules and lengths according to applicable standards and project requirements.

Kamal Steels is a Stainless Steel 347 Seamless Pipes Manufacturer & Stockist in India, supplying SS 347 Seamless Pipes in standard and customized sizes, schedules, wall thicknesses, and lengths. Products can be supplied with applicable testing, inspection, material certificates and documentation according to customer and project specifications.

Actual pipe dimensions, tolerances, and outside diameters are determined according to ASTM, ASME, and ANSI dimensional standards. The appropriate size should be selected based on pressure rating, flow capacity, and process requirements.

The weight of SS 347 Seamless Pipes varies according to the outside diameter, wall thickness, schedule, and overall pipe length. Higher schedules provide greater wall thickness and improved pressure-handling capability, resulting in increased weight per metre.

The values shown above are approximate theoretical weights. Actual pipe weights may vary depending on manufacturing tolerances, dimensional standards and production processes.

Stainless Steel 347 Seamless Pipes are manufactured in a wide range of pipe schedules to suit varying operating pressures and temperatures. Selecting the correct schedule is essential for ensuring the required strength, wall thickness, and long-term performance in industrial piping systems. The schedule should always be selected according to design pressure, service temperature, and applicable piping standards.

Actual wall thickness varies according to the nominal pipe size and dimensional standards such as ASME B36.19M. Kamal Steels supplies SS 347 seamless pipes in multiple schedules to meet project-specific requirements.

ASTM A312 TP347 Seamless Pipe is a niobium (columbium) stabilized austenitic stainless steel pipe designed for high-temperature service and excellent resistance to intergranular corrosion. The addition of niobium minimizes chromium carbide precipitation during welding, allowing the material to maintain superior corrosion resistance without requiring post-weld heat treatment in many applications.

ASTM A312 TP347 seamless pipes are widely used in refineries, petrochemical plants, power generation facilities, heat exchangers, pressure vessels, boilers, chemical processing units, thermal processing equipment, and other applications involving continuous exposure to elevated temperatures. The material provides excellent oxidation resistance, good mechanical strength, outstanding weldability, and long service life under demanding operating conditions.

Kamal Steels supplies ASTM A312 TP347 Seamless Pipes in various sizes, wall thicknesses, schedules, surface finishes, and custom lengths with complete Material Test Certificates (MTC), third-party inspection, and export-quality packaging to meet domestic and international project requirements.

SS 347 and SS 321 are stabilized austenitic stainless steel grades specifically developed for elevated-temperature service and resistance to intergranular corrosion after welding. The primary difference lies in their stabilizing elements. SS 347 contains niobium (columbium), while SS 321 contains titanium. SS 347 generally offers improved creep resistance and superior performance during prolonged exposure to high temperatures, making it a preferred material for pressure vessels, boilers, and refinery equipment. SS 321 is widely selected for heat exchangers, exhaust systems, and general high-temperature process piping.

Stainless Steel 347 pipes are available in both seamless and welded construction. Seamless pipes are manufactured from solid billets without a longitudinal weld seam, providing excellent strength for high-pressure and high-temperature applications. Welded pipes are produced by forming stainless steel plate or strip and welding the joint, making them a cost-effective solution for general industrial applications where design specifications permit.

The selection between seamless and welded SS 347 pipes depends on the operating pressure, service temperature, corrosion environment, project specifications and applicable piping standards. Kamal Steels supplies both seamless and welded stainless steel pipes in accordance with ASTM and ASME standards.

Stainless Steel 347 Seamless Pipes contain chromium, nickel, and niobium as the principal alloying elements. The addition of niobium stabilizes the stainless steel structure and helps reduce the risk of chromium carbide precipitation during prolonged exposure to elevated temperatures. This composition provides good corrosion resistance and supports reliable performance in high-temperature industrial applications.

The chemical composition of SS 347 Seamless Pipes should be verified against the applicable ASTM or ASME specification and the material test certificate supplied with the product.

Stainless Steel 347 Seamless Pipes provide a combination of tensile strength, yield strength, elongation, and toughness suitable for demanding industrial piping applications. The stabilized austenitic structure supports reliable performance during elevated-temperature service and helps maintain resistance to intergranular corrosion under suitable conditions.

Actual mechanical properties may vary according to the applicable product specification, pipe dimensions, heat-treatment condition, and testing requirements. Final values should be confirmed against the relevant standard and material test certificate.

Stainless Steel 347 Seamless Pipes are used in applications requiring corrosion resistance, thermal stability, and dependable performance at elevated temperatures. The niobium-stabilized composition makes the grade suitable for applications involving prolonged thermal exposure and demanding process conditions.
