Production process description
The raw material for rolling seamless carbon steel pipes is round tube blanks, which are cut into blanks by a cutting machine and sent to the furnace for heating via conveyor belts. The billet is fed into the furnace and heated at a temperature of approximately 1200 degrees Celsius. The temperature control in the furnace is a key issue. After the round tube is out of the furnace, it must be pierced through a pressure punching machine. The inner diameter of the steel pipe is determined by the length of the outer diameter of the drill bit of the sizing machine. After the steel pipe is sized, it enters the cooling tower and is cooled by spraying water. After the steel pipe is cooled, it will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection. If there are cracks, bubbles, etc. inside the steel pipe, it will be detected. After the quality inspection of steel pipes, they must be selected strictly, and painted with serial numbers, specifications, and production batch numbers. It is hoisted into the warehouse by a crane.
