Ductile Iron Pipe Fittings Rubber Ring Installation

1. The installation of ductile iron pipe fittings should be based on the design, using an observer and a spirit level to find the installation surface. The bottom of the ditch should be neat and tidy, and it is necessary to avoid placing the pipe on the convex surface of the bottom stone. The direction of water flow in ductile iron pipe fittings is closely related to the direction of the socket. Normally, the direction of water flow in ductile iron pipe fittings should flow from the socket to the socket, but in the case of a large slope, the socket of the ductile iron pipe fitting should face upwards. , The ductile iron pipe fittings are installed from bottom to top. When ductile iron pipe fittings go down the groove, avoid strong collision between the bottom and the wall.

2. Socket cleaning. Inside the socket of ductile iron pipe fittings, use a brush and a clean rag to clean the inside of the socket, especially the position where the ductile iron pipe sealing ring is placed. There should be no paint, soil, sand, etc. residues.

3. Lubricate the rubber ring and socket. Clean the edge of the ductile iron fitting socket and lubricate the apron and ductile iron fitting socket with lubricant.

4. Installation of rubber ring for ductile iron pipe fittings. Forcefully bend the ductile iron pipe fitting rubber ring into a gourd shape. Put the rubber seal in the socket, check for fit, then lubricate with lubricant.

5. Links. When connecting ductile iron pipe fittings, different tools should be used for ductile iron pipe fittings with different diameters.
