Chemical engineering, petroleum and new energy pipeline transportation belong to high-risk industrial scenarios, which put forward ultra-high requirements for the pressure resistance, sealing and corrosion resistance of metal pipes. Different from welded steel pipes, high-precision seamless pipes adopt one-piece piercing and rolling forming technology, with no welding seam on the whole pipe body. The pipe wall has uniform thickness, stable internal structure and excellent pressure-bearing performance, which can resist the impact of high-pressure fluid and the erosion of corrosive chemical media for a long time. After finishing heat treatment and precision sizing, the products have accurate dimensional tolerance and good sealing fit effect. They can effectively avoid pipeline leakage, explosion and other safety hazards, greatly improving the operational safety and stability of industrial transmission pipelines. They are widely used in long-distance oil and gas transportation, chemical medium delivery and energy equipment supporting pipelines, serving as the safety barrier for industrial energy transmission.
