Executive Standard:GB/T 19685, AWWA C301 Armored Coupling Prestressed Concrete Cylinder Pipe is a technology improvement product of PCCP, which is a fasten joint mode predesigned to effectively overcome the inner axial thrust of pipeline. It’s usually used in the turning point, variable cross-section, connecting point of the pipe and fitting and the end point of the pipeline. Armored coupling structure is to set a prevent thrust ring in the spigot and socket, to fix the ring with the groove-typed armored coupling clasp to form the armor, making the axial thrust transfer through the pipes.
