Attention to details of water supply pipe fitting processing and bonding
In order to improve the work efficiency and quality of water supply pipe fittings, we should pay more attention to some details in the process of construction, mainly involving the processing and bonding of water supply pipe fittings. How are these two important construction links operated specifically?
First of all, it is about the processing of water supply pipe fitting. First, take a certain length of pipe material, and then use hacksaw to cut the saw manually or circular saw blade and saw machine to cut the saw. Both ends of the cut should be kept flat, with butterflies dwarfed and chamfered, chamfered should not be too large.
The second is the adhesive of water supply pipe fitting, which must be assembled before bonding, clean the outer surface of the pipe end about 50mm and the inner wall of the pipe fitting acceptance mouth, and then scrub with cotton yarn coated with acetone, and then evenly apply a layer of adhesive with a brush on the two bonding surfaces, without leakage.
After applying adhesive to the water supply pipe fitting, rotate it to the ideal combination Angle, insert the pipe into the receiving mouth of the pipe fitting, and knock with mallet, so that all the pipe is inserted into the socket, cannot be disassembled or changed direction within two minutes, timely wipe away the glue extricated at the joint to keep the pipe clean.
If there is a riser, it is required to install one expansion joint in each layer to compensate for the hot expansion and cold contraction of the countercurrent pipe. If the height of each pipe is within 3m, a pipe hoop shall be considered; Pay attention to the direction of water when installing the tee; The transverse tube shall be fitted with a fashion sling at 0.6m intervals. If the straight line distance of horizontal pipe and drain pipe is greater than the prescribed distance, inspection or cleaning mouth should be set up.
These are the water supply pipe construction process needs to pay attention to the details of the problem, whether it is processing or bonding to be carried out in accordance with the requirements, so as to ensure that the water supply pipe can be smoothly installed in place, and normal use, reduce the possibility of leakage and other problems.
