Large Diameter Seamless Steel Pipe

Seamless Steel Pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. The seamless pipe is then finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 32 inch OD. Carbon Steel Seamless Pipes / Tubes Carbon steel is an alloy consisting of iron and carbon. The percentage of carbon in the steel affects the hardness, strength of elasticity and ductility of carbon steel. Seamless carbon steel pipe or solid steel ingot is made of the capillary tube through the hole, then through the hot-rolled, cold rolled or cold drawn is made.

Product Details

Seamless Steel Pipe is a type of steel tubing manufactured without welded seams, ensuring a smooth and uniform surface. It is produced by heating a solid steel billet and shaping it through hot or cold rolling processes. This type of pipe is highly regarded for its strength, durability, and corrosion resistance, making it suitable for various industries such as oil and gas, construction, automotive, and machinery manufacturing. Seamless Steel Pipe is commonly used in applications that require reliable performance in high-pressure and high-temperature environments. The absence of welded seams eliminates weak points, ensuring structural integrity and longevity. Seamless Steel Pipe is widely utilized for fluid and gas transport in critical applications where precise dimensions and consistency are essential, making it a preferred choice for pipelines, construction projects, and industrial applications requiring seamless and dependable piping solutions.
