During the construction of ductile iron pipes, the quality of the lower pipes determines the reliability and quality of operation and other factors. According to the characteristics and characteristics of ductile iron pipes, it is recommended to adopt the following forms of lowering operations:

1. Lowering the pipe: The ductile iron pipe should be lowered to the bottom of the tank according to the requirements of the pipe, usually by manual lowering or mechanical lowering.

2. Push the pipe to insert it into the socket: during installation, it is more labor-saving and smooth to insert the socket into the socket. First, put the socket into the socket of the ductile iron pipe and press the socket on the rubber ring in the socket, connect the wire rope and the rewinding chain, and tighten the rewinding chain; until the socket is inserted into the socket all in place, and ensure that the outer edge of the socket reaches the rubber ring The circles are the same distance.

3. Clean the apron and install the apron: wipe off the sticky matter on the apron to ensure that each part of the apron is not warped or twisted, and is evenly stuck in the groove.
