Product Introduction:

Qingdao Century Pipeline Industry's Ductile Iron Insulated Pipes are one of the company's main products, manufactured with advanced international production techniques and a rigorous quality control system. The range covers all models from DN80mm to DN2600mm, with a stock of ten thousand tons to ensure ample supply and efficient shipment. The product uses low-phosphorus and low-sulfur high-quality cast iron, processed through precise procedures such as centrifugal casting and annealing, resulting in a dense tube structure and high carbon balling rate. It boasts high strength, excellent elongation, and excellent corrosion resistance. It also features an efficient insulation and protective layer design, significantly reducing heat loss during transmission and meeting the heating and heating needs of complex environments like cold and extreme cold. The product interfaces use a T-type flexible design for reliable sealing, capable of adapting to vibrations and thermal expansion and contraction during construction, significantly reducing the risk of leakage. It is widely used in urban centralized heating networks, industrial steam transmission, and residential heating systems. The company strictly adheres to international standards such as GB/T13295-2013 and ISO2531, has passed the ISO9001 quality management system certification, and has established a comprehensive pre-sales consultation, in-sales installation guidance, and after-sales follow-up service system. With stable product quality and professional services, it has become a trusted supplier in the domestic thermal insulation pipeline field, with products exported nationwide and worldwide.
