The primary sources of raw materials used in flange manufacturing include Shanghai Baosteel, Jiangyin Xingcheng Special Steel, Shagang Group, Wugang Daye Special Steel, Zhejiang Dalong Special Steel, and Taiyuan Stainless Steel Plant, among others. Upon arrival at the plant, all materials undergo sampling for chemical and spectral analysis, as well as visual inspection, defect assessment, and dimensional verification, based on their furnace batch numbers; only those that pass these checks are approved for use. The manufacturing process is controlled through “Process Control Cards.” Prior to shipment, all products are subjected to 100% inspection of dimensions and hardness, and alloy steel and stainless steel products undergo 100% PMI testing. The company holds Class A and Class B manufacturing licenses for special equipment and is certified under ISO 9001 quality management.
