Qingdao Zhongyi Steel Co., Ltd. is a leading manufacturer, supplier, and factory of steel pipes in China. Our steel pipes undergo a rigorous manufacturing process to ensure superior quality and durability.
The steel pipe manufacturing process starts with raw materials such as steel coils and sheets that are cut into the desired size and shape. The pieces are then welded together using various techniques such as electric resistance welding, high-frequency welding, or submerged arc welding. After welding, the pipes undergo a heat treatment to strengthen and improve their mechanical properties.
To ensure that our steel pipes adhere to international standards and customer specifications, we subject them to various tests such as hydrostatic testing, ultrasonic testing, X-ray testing, and mechanical testing.
