Seamless Tubes Manufacturer

At Steel Icon Stainless Pvt. Ltd., we are a trusted manufacturer and global exporter of seamless tubes, delivering solutions for industries that demand precision, reliability, and superior strength. Our seamless tubes are crafted using cold drawn or hot rolled extrusion methods, ensuring tight dimensional tolerance, smooth internal finish, and high-pressure handling capabilities.

We manufacture seamless tubes in a wide range of stainless steel, carbon steel, alloy steel, and duplex grades, adhering to global standards such as ASTM, ASME, DIN, EN, and ISO. Our tubes are widely used in heat exchangers, boilers, condensers, instrumentation, hydraulic systems, oil & gas, power plants, and automotive sectors.

What Are Seamless Tubes?

Seamless tubes are cylindrical hollow components produced without welding seams, offering consistent wall thickness and improved mechanical strength. The absence of welds makes them ideal for high-pressure and high-temperature environments, as well as precision-engineered systems that require smooth internal flow.

These tubes are available in various forms including round, square, and rectangular cross-sections, and are often used in fluid conveyance, structural applications, and heat transfer systems.

Ask A Question >
What is the main difference between seamless tubes and welded tubes?
Seamless tubes are stronger and more uniform, with no weld seam, making them better for high-pressure or precision applications.
Do you supply U-bend and custom-shaped tubes?
Yes, we manufacture U-bend and other custom tube geometries for heat exchangers and tight installations.
What is the difference between seamless pipes and seamless tubes?
Pipes are used for transporting fluids, while tubes are used in structural and precision systems with tighter tolerances.
Are your tubes suitable for corrosive environments?
Absolutely. Our SS 316 and duplex tubes offer excellent corrosion resistance.
What is the lead time for bulk pipe orders?

Standard orders ship within 3-7 days, while custom orders take 7-14 days, depending on requirements.
