Product Introduction:

Qingdao Century Ductile Iron Pipe Industry's flexible cast iron drainage pipes are a top choice in the building drainage field. The products cover various interface types including A, B, and W, with specifications ranging from Φ50 to Φ300mm, meeting the drainage needs of various civil and industrial buildings. The products are produced in strict accordance with the GB12772-2008 national standard, utilizing advanced centrifugal casting technology, resulting in dense pipe structure, uniform wall thickness, and smooth inner and outer walls. They offer high strength and excellent corrosion resistance. Their tensile strength far exceeds that of traditional plastic pipes, combined with flexible joint design, providing strong resistance to bending, stretching, and seismic performance. The system can maintain a seal without leakage within 35mm of axial deformation and 31.5mm of lateral vibration bending. These drainage pipes also offer superior noise reduction, with graphite in cast iron effectively cushioning vibration and reducing water flow noise, significantly lower than that of PVC pipes, making them particularly suitable for quiet environments such as residential, hospitals, and schools. Additionally, the product has high-temperature resistance and flame-retardant properties, will not deform or produce toxic gases at high temperatures, and is environmentally friendly and non-toxic, preventing secondary pollution of wastewater. The pipes are 100% recyclable and reusable. In terms of installation, different interface types have their advantages. The W-type has a small radial size and easy assembly, while the A-type offers high interface strength and good sealing. They can be flexibly matched for different scenarios such as drainage trunk and riser pipes, significantly improving construction efficiency and quality. With exceptional performance and reliable quality, this product is widely used in building indoor and outdoor domestic drainage, rainwater discharge, and non-corrosive industrial wastewater discharge projects, providing a solid guarantee for the stable operation of the building drainage system.
