Liaocheng Tiankai Pipe Industry Co., Ltd. in Dongchangfu District, Liaocheng City specializes in manufacturing various sizes of ductile iron pipes and fittings. We are a manufacturer of ductile iron pipes. Our company has always adhered to and implemented the quality policy of "Quality is the foundation of survival of the enterprise, and providing products and services that meet customer needs is our eternal pursuit."

The ductile iron pipes produced by our company can withstand high internal pressure, with test pressures exceeding both international and European standards by 1MPa during hydraulic tests. These pipes also offer excellent resistance to external pressure, which reduces the requirements for pipe bedding and protective coating, ensuring both economic and reliable pipeline installation.

Additionally, measures such as zinc spraying, asphalt paint spraying, and cement lining ensure the internal and external corrosion resistance of the cast pipe. Our zinc spraying quality meets the ISO 8179 specifications, with a minimum zinc coating of 130g per square meter, asphalt paint thickness of not less than 70μm, and cement mortar lining quality in compliance with ISO 4179, ensuring the mortar is solid, tight, smooth, and has strong adhesion.

Centrifugal cast iron pipes are manufactured using advanced water-cooled casting equipment and new technologies both domestically and internationally. The products are produced and inspected in strict accordance with the ISO 2531 international standard, ensuring each pipe has excellent mechanical properties and a long service life. Supported by excellent facilities, strong technical capabilities, and a scientifically advanced management system, the company supplies centrifugal cast iron pipes and accessories that feature high strength, high elongation, smooth appearance, and corrosion resistance. These products are mainly used for main fluid pressure pipelines in urban water supply, tap water, city networks, fire protection projects, garden communities, and other applications. Available pipe sizes range from DN100 to DN800.

The company adheres to the corporate philosophy of "focusing on customer needs and aiming for customer satisfaction." We actively recruit management and technical talents in the foundry industry, leveraging the regional resource advantages and convenient transportation environment. We strictly adhere to the ISO 9001:2000 quality management system certification standards to build a modern foundry enterprise with a high starting point, high quality, and high standards. We provide customers with products and services, and we sincerely welcome friends from all walks of life to visit our company for examination and cooperation!
