Product Introduction:

Qingdao Century Pipe Industry's water supply ductile iron pipes are one of the company's core products. They are produced strictly in accordance with the national standard GB/T 13295—2013, covering the full range of models from DN80mm to DN2600mm. A stock of 10,000 tons ensures ample supply and efficient shipment. The product uses high-quality casting iron with low phosphorus and sulfur, processed through centrifugal casting, annealing, and other precise procedures. The graphite nodules have a high degree of spheroidization, the pipe body has a dense structure, and it combines the corrosion resistance of cast iron pipes with the toughness and strength of steel pipes. The tensile strength can reach over 500MPa, and the pressure resistance exceeds 3MPa, effectively resisting impacts, vibrations, and soil settlement. The product is equipped with various flexible joints such as T-type, K-type, and S-type, ensuring reliable sealing and adapting to thermal expansion and contraction during construction, significantly reducing the risk of leakage. The inner wall is treated with a special coating, meeting the requirements for drinking water transportation. The company relies on advanced production technology and strict quality control, has passed the ISO9001 quality management system certification, and has a professional installation technical team for full guidance. The product, with its excellent quality, is exported to both domestic and international markets, widely used in municipal civil engineering such as urban water supply and residential secondary water supply, becoming the preferred pipe material in the water supply pipeline field.
