Shandong Zhongyue Steel Group Co.,Ltd, headquartered in Shandong Province, China, is a leading high-tech enterprise specializing in seamless steel pipe production, steel structure manufacturing, and intelligent logistics services. It covers an area of 150,000 square meters and has a total investment of 176 million U.S. dollars.
Our company is equipped with over a dozen large-scale devices such as laser cutting machines, shot blasting machines, and CNC flame cutting machines, and serves nearly 600 customers.
We have a stock of nearly 15,000 tons of seamless steel pipes and can ship them directly.
Focusing on the entire process of seamless steel pipe and steel structure manufacturing, from raw material control to finished product delivery, a strict quality management system is established. Through standardized operations and precise detection methods, stable and reliable product quality is ensured, laying a solid quality foundation for the project.
For raw materials such as seamless steel pipe blanks and steel used in steel structures, multi-dimensional tests including chemical composition and mechanical properties are carried out in accordance with national standards and enterprise standards. Retain quality reports of each batch of raw materials, establish traceability files, and avoid quality risks from the source.
The seamless steel pipe focuses on the dynamic monitoring of the parameters of the rolling mill and the heat treatment curve. Workers record the wall thickness tolerance and ellipticity every hour. The steel structure focuses on the welding current and groove Angle, and adopts a welding process monitoring system to issue real-time early warnings of deviations. For key processes (such as steel pipe straightening and pre-assembly of steel structures), "quality sentries" are set up, with senior quality inspectors standing by to supervise, ensuring that the process implementation is error-free.
For the welding of steel structures, a system of certified welders and welding process qualification should be implemented. When using processes such as arc welding and submerged arc welding, the welding current and groove Angle should be strictly controlled. With the aid of a three-dimensional coordinate measuring instrument, a full inspection of the component dimensions and hole position accuracy is carried out to ensure the installation compatibility of the steel structure.
