Seamless Pipes Manufacturer
At Steel Icon Stainless Pvt. Ltd., we are a leading manufacturer and global supplier of seamless pipes, engineered for exceptional strength, leak-proof performance, and resistance to high pressure and temperature. Our seamless pipes are manufactured using piercing and extrusion methods, ensuring a homogeneous structure and smooth internal surface without any welding seams.
We supply seamless pipes in a wide range of stainless steel, carbon steel, alloy steel, and duplex grades, fully compliant with global standards such as ASTM, ASME, EN, DIN, and API. Our products are widely used in oil & gas, chemical, petrochemical, power generation, marine, and engineering sectors.
What Are Seamless Pipes?
Seamless pipes are manufactured without any welds or joints, resulting in superior strength and corrosion resistance. They are produced by hot rolling or cold drawing a solid billet over a piercing rod to create a hollow shell. This makes seamless pipes ideal for critical applications where high pressure, high temperature, and aggressive media are present.
Compared to welded pipes, seamless pipes offer better mechanical integrity, uniformity, and reliability in high-performance environments.

Frequently Asked Questions
Explore our FAQs for insights on materials, customization, and delivery.
Why are seamless pipes preferred in critical industries?
They offer better strength, uniformity, and no weak points like welds, making them ideal for pressure-sensitive applications.
Are seamless pipes available in both hot rolled and cold drawn forms?
Yes. We manufacture hot rolled for heavy-duty use and cold drawn for tight tolerance requirements.
Can I request custom lengths and grades?
Absolutely. We offer cut-to-length and non-standard alloy options based on your project needs.
Do you supply test certificates and third-party inspection?
Yes. All pipes come with mill test certificates (MTC) and optional third-party inspections (TPI).
