Flexible cast iron pipes, also known as cast iron drainage pipes, flexible seismic cast iron drainage pipes, machined cast iron drainage pipes, flexible joint cast iron drainage pipes, centrifugal cast iron drainage pipes.Suitable for new, expanded, and renovated civil and industrial buildings, both indoor and outdoor piping with diameters ranging from DN50mm to DN300mm, and internal pressure not exceeding 0.3MPa.Push-fit and clamp connectionsGray iron with sleeve connectionCast iron pipes and their accessories for residential drainage systems, stormwater pipes, non-corrosive industrial wastewater pipes, and downspouts.

The W-type flexible cast iron drainage pipe is a commonly used connection method in China. Besides its excellent flexibility and seismic performance, it also features synchronous construction capability, high material utilization, ease of pipeline cleaning, reduced number of hydrostatic tests, shortened construction period, and improved economic benefits. Additionally, the joints of this type are secured with bolts on the outside, avoiding the defects of easily damaged flanges on the flexible socket joints and the difficulty in fixing bolts near the wall. It boasts simplicity in operation and other advantages, making it highly competitive in the selection of building drainage pipes and fittings.
