球墨铸铁管连接安装程序为:
清理承口插口→清理胶圈→上胶圈→下管(排管)→在插口外表和胶圈上刷润滑剂→顶推管子使之插入承口→检查。 
安装要点: 
①、清理管口:将承口内的所有杂物清除擦洗干净。 
②、清理胶圈、上胶圈:将胶圈上的粘着物清擦干净,把胶圈弯为“梅花形”或“8”字形装入承口槽内,并用手沿整个胶圈按压一遍,或用橡皮锤砸实,确保胶圈各个部分不翘不扭,均匀地卡在槽内。 
③、在插口外表面和胶圈上涂刷润滑剂:将润滑剂均匀地涂刷在承口安装好的胶圈内表面、在插口外表面涂刷润滑剂时要将插口线以外的插口部位全部刷匀。 
④、下管:应按下管的要求将管子下到槽底,通常采用人工下管法或机械下管法。 
⑤、安装机具设备:将准备好的机具设备安装到位,安装时注意不要将已清理的管子部位再次污染。

The installation procedure of ductile iron pipe connection is as follows:


Clean socket and spigot → clean rubber ring → upper rubber ring → lower pipe (discharge pipe) → brush lubricant on socket surface and rubber ring → push pipe to insert into socket → check.


Installation points:


① Cleaning the nozzle: clean all the sundries in the socket.


② Clean up the rubber ring and upper rubber ring: clean up the adhesive on the rubber ring, bend the rubber ring into "plum blossom" or "8" shape and put it into the socket groove, and press it along the whole rubber ring by hand, or smash it with a rubber hammer to ensure that all parts of the rubber ring are not warped or twisted and evenly stuck in the groove.


③ Apply lubricant on the outer surface of socket and apron: apply lubricant evenly on the inner surface of apron installed at socket, and apply lubricant on the outer surface of socket. When applying lubricant on the outer surface of socket, all the socket parts outside the socket line shall be evenly brushed.


④ Pipe laying: the pipe shall be laid down to the bottom of the groove according to the requirements of the pipe, usually by manual laying or mechanical laying.


⑤ Installation of machinery and equipment: the prepared machinery and equipment shall be installed in place, and the cleaned pipe parts shall not be polluted again during installation.
