ERW426 API high precision tube mill making machine for Oil and Gas
Forming and sizing units uses combination of FF forming and FFX forming to produce steel pipes through HF induction welding. Heating method uses HF induction or contact welding, i.e. steel pipe fed into the mill is formed into pipe profile by forming rolls. With skin effect and proximity effect of high frequency current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe to heat it up quickly to welding temperature, and finishes pressure welding when pipe fringes squeezed together by squeezing roll. After normalizing, cooling, sizing and primary straightening, steel pipe of desired size is produced. Advantage of the line: More shared rolls, easy adjustment, high quality weld seam, sturdy machine frame, easy operation and maintenance.
API model mainly produces high level steel pipes, such as delivery pipe of petroleum and natural gas, oil well casing and so on. The requirements for material and quality are very strict. The mill is equipped with section equipment and technological equipment, such as IF annealing, air-cooled roll table, ultrasonic inspection, high pressure hydraulic pressure testing machine and so on.
