Sewage Pipe Relining Project
Guangzhou Road of Tanggu in Tianjin, Sewage Pipeline has been used for nearly 20 years, the diameter of the pipeline DN600, DN700, DN800, the material for the dilute salt reinforced concrete pipe. Pipeline depth of 1.5 m -4 m. the pipeline has been seriously corrosive and leakage, the maximum corrosion wall thickness of more than 60%, the interface corrosion is serious, groundwater infiltration, parts of the road are collapsed. Because the road is very busy, to replace whole pipeline is very difficult for c
Ningxia Hening Chemical Co., Ltd. Waste Water Tank
HDPE CPL lined concrete tank was use for the storage of waste water which contains low concentration of acid. The mechanical connection between the CPL and concrete insured the durability of the tank. The connection between the HDPE CPL sheets was achieved by extrusion welding. And all the welding joints all passed the by sparkling test.
