In the municipal construction, a complete drain pipe system is a must. It directly determines whether the urban sewage, rainwater and other wastewater can be optically treated or recycled, and whether water resources can be scientifically developed. Drainage pipes and fittings are without doubt the most important part in a municipal drain system. At Kingbull, we supply a wide selection of pipes and fittings for the installation of reliable drain pipe networks of a city. They are available in HDPE, FRPP, PVC-U and more material options.
