Flexible cast iron pipe fittings

It has the advantages of small fittings in radial size, convenient arrangement, space saving, length can be cut on site as required, pipe saving, convenient disassembly, maintenance and replacement, etc. Besides the flexibility and good seismic performance of the connection, it also has the characteristics of synchronous construction, high utilization rate of pipes, convenient pipeline clearing, reduced hydraulic test times, shortened construction period and improved economic benefits. In addition, the corresponding type of interface is fastened with bolts on the outside, which avoids the defects that the flexible interface flange of the socket is easy to be damaged and the bolts against the wall feet are difficult to fix, and has the advantages of simple operation, so it has strong competitiveness in the selection of building drainage pipes and fittings.
