Liaocheng Tiankai Pipe Industry, located in Dongchangfu District, specializes in manufacturing various sizes of ductile iron pipes and pipe fittings. We are a manufacturer of ductile iron pipes. Our products are of high quality, and we consistently adhere to and implement the quality policy of "Quality is the foundation of the company's survival, and providing products and services that meet customer needs is our eternal pursuit."

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

Additionally, measures such as external zinc coating and internal cement lining ensure the internal and external corrosion resistance of the cast pipe. The small zinc spray quantity per square meter of pipe is 130g, the thickness of liqingqi is not less than 70μm, and the quality of the cement mortar lining meets the ISO 4179 specifications, ensuring the mortar is strong, compact, smooth, and has strong adhesion.

Centrifugal ductile iron pipes are manufactured using advanced water-cooled casting equipment and cutting-edge technology from both domestic and international sources. The products are produced and inspected in strict accordance with ISO 2531 international standards, ensuring each pipe exhibits excellent mechanical properties and a long service life. Supported by sophisticated facilities, robust technical expertise, and a scientifically advanced management system, the company offers centrifugal ductile iron pipes and accessories with high strength, high elongation, smooth appearance, and excellent corrosion resistance. These products are primarily used for main fluid pressure pipelines in urban water supply, tap water, city networks, fire protection projects, garden communities, and more. 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 high starting point, quality, and standards.
