What is the procedure for the socket connection of a plastic-coated composite steel pipe?

Inner plastic ductile iron pipe and socket connection plastic composite steel pipe embedded underground pipeline can use T-type flexible interface. Installation requirements 1. Before the construction, do a visual inspection of the pipe, pipe fittings, rubber rings, etc., and find that any problem can not be used. 2. The installation procedure is: cleaning the socket mouth, cleaning the apron, rubber ring, lower tube, brushing the lubricant on the outer surface of the socket and the apron, pushing the tube into the socket, checking 3, installation points: clean up all the debris in the mouth to remove clean scrub; clean apron, glue ring: remove the adhesive on the apron to wipe clean, into the socket slot, and hand pressed along the entire apron; Apply lubricant to the outer surface of the socket and the apron, and evenly apply the lubricant to the inner surface of the apron installed on the socket. When the lubricant is applied to the outer surface of the socket, all the socket parts except the socket line should be brushed. Uniform; Lower tube: The tube should be pushed down to the bottom of the tube according to the requirements of the tube. Usually, the artificial lower tube method or the mechanical lower tube method is used; the equipment equipment is installed: the prepared equipment equipment is installed in place, and the installation is careful not to clean the tube. The tube part is again contaminated; the push tube is inserted into the socket: firstly, the socket is prevented from entering the socket; the socket is pressed against the apron in the socket; and the wire rope and the reverse chain are connected, and the reverse chain is pulled; The tube can be shaken to the side of the tube socket until the socket is fully inserted and the distance from the outer edge of the socket to the apron is the same. Fitting of the tube: Due to the light weight of the tube, a single wire rope is used during installation. In this case, it is easy to deflect the tube and it cannot be installed in place. Therefore, the double inverted chain parallel force method can be adopted to make the pipe fittings installed in parallel, and the apron will not be squeezed. Check: Check whether the position of the socket and the socket meets the requirements. Information Sources:
