Introduction to Seamless Pipe
Seamless pipes are pipes that are manufactured without any welding seams. They are produced from solid round steel billets which are heated and pierced through the center to form a hollow tube. This manufacturing process gives seamless pipes several advantages over welded pipes, such as high strength, better pressure resistance, and improved durability. Seamless pipes are widely used in various industries, including oil and gas, petrochemical, power generation, automotive, and construction, due to their excellent performance in transporting fluids and gases under high pressure and temperature conditions.
