High-density polyethylene (HDPE) double-wall corrugated pipe is a pipe with corrugated structure, which is processed by extrusion molding by adding necessary additives to high-density polyethylene (HDPE) as the main raw material. The inner wall is smooth and smooth, the outer wall is corrugated, and the inner and outer walls are hollow and tightly welded ring structure. Corrosion resistance, long service life; The inner wall is smooth, and the flow friction resistance is small; Integrated molding, uniform performance and other advantages. What do we need to pay attention to when installing?

(1) The socket should follow the direction of the water flow and the socket is the direction of the reverse water flow;

(2) The pipe should be vertically flat after adjustment;

(3) When the interface is operated, the inner and outer work of the socket and socket should be cleaned first, and the rubber ring should be checked whether it is complete;

(4) The central axis of the socket must be aligned with the central axis of the socket.
