Product Description

Seamless Steel Pipe is a type of steel pipe made from a single piece of metal without any welding or joints. It is widely used in various industries such as oil and gas, construction, and mechanical engineering due to its high strength, durability, and corrosion resistance.
Our Seamless Steel Pipes are available in different materials such as carbon steel, alloy steel, and stainless steel, and are manufactured in accordance with international standards such as ASTM, DIN, and JIS. The size range of our pipes is from 1/8" to 36" in outer diameter (OD) and from SCH 10 to SCH XXS in wall thickness (WT).
We offer our Seamless Steel Pipes in fixed lengths of 6 meters or 12 meters, or in random lengths up to 12 meters. The pipes can be surface treated with black, galvanized, or varnished finishes, and can be packed in bundles or as per customer's requirements.
Our Seamless Steel Pipes are certified by ISO, API, and CE, ensuring the highest quality standards. With our extensive experience and expertise, we are committed to providing our customers with the best quality products and services.
