Water supply pipe fittings 9

Processing of water supply fittings: After determining the length of the pipe, it can be manually cut with a steel saw, circular saw blade, or sawing machine. The two ends of the incision should be kept flat, and the burrs should be removed and chamfered with butterfly shavings. The chamfer should not be too large.

Adhesive bonding of water supply fittings: Before bonding, a trial assembly must be carried out, and the outer surface of the inserted pipe end, about 50mm in length, and the inner wall of the fitting socket must be cleaned. Then, a cotton yarn coated with acetone should be used to scrub it once, and a layer of adhesive should be evenly applied to the bonding surface of the two with a brush, without any omissions. After coating, rotate to the ideal combination angle, insert the pipe into the socket of the pipe fitting, tap with a wooden mallet to fully insert the pipe into the socket, and do not open or change direction within two minutes. Timely wipe off the adhesive extruded from the joint to keep the pipe clean. Install one expansion joint on each layer of the riser to compensate for the thermal expansion and contraction of the reflux pipe. When installing three-way pipes, pay attention to the direction of the water flow to facilitate the natural formation of a slope when installing horizontal pipes. For vertical pipes with a height of less than 3m, consider installing one pipe clamp. Install a hoist every 0.6m for the horizontal pipe. When the straight distance between horizontal pipes and drainage pipes exceeds the specifications in Table 4, inspection or cleaning ports should be set up.
