The procedure for working with metal -plastic pipes and fittings
Metal -plastic pipes are sold in bays twisted in a spiral. The metal -plastic pipe consists of three layers: the inner layer is food polypropylene, the middle layer is aluminum, the outer layer is plastic. These layers are connected by special glue.
Pipe bend
Flexion and unbend metal -plastic pipes must be carefully, otherwise it can be broken. For safe bending, special springs are sold, the spring is inserted into the pipe, so that it is inside the pipe at the site of the alleged fold, after which you can slowly and carefully bend the pipe, the spring inside will not let the pipe break, after bending, the spring is removed. If you do not have such a spring or the bend goes far from the edges of the pipe, you can bend the pipe without it, for this it is necessary to grab it with your hands, resting at it with your thumbs. The distance between the thumbs should be small, about five centimeters, after which you need to bend the pipe a little, then move your hands to the side and bend the pipe a little more, but about the first cod about the first cod. Thus, for 5-6 bends, the pipe can be bent 90 degrees.
Pipe trimming
Marking the right amount of the pipe, carefully cut it with a special pipeline - a special tool for cutting metal -plastic pipes. If you cut a metal -plastic pipe with a regular knife, it can be flattened at the end and it will be difficult to put fitting on such a cut. In specialized stores, you can help you cut the pipe, but you need to know the exact dimensions. Even if the pipe was cut by a special pipeline, its cut, most likely, will not be perfectly round, this is still due to deformation of the pipe itself. To give a cross cut of the round -shaped pipe, a calibrator is used, it also removes the internal chamfer of the pipe for a lighter planting on the fitting fitting. If the cut shape is even and round, then the chamfer can not be removed, since there is also a chamfer on the fitting fittings. You can replace the calibrator with any solid object of a cylindrical shape with a flat round cross section, suitable in size for this.
Installation of fitting
Before installing the fitting on the pipe, it is necessary to remove the rug nut and the squeezing ring, before connecting the pipe with the fitting fitting, you need to put on the nut, then the squeezing ring, after which tightly insert the fitting into the pipe, while turning a little the pipe from side to side. There should be several rubber rings on the fitting for sealing the connection, they should be located exactly in the grooves that are provided for them on the fitting. In order for the rubber rings to not fly when the fitting is introduced into the pipe, they can be lubricated with a soap solution. After the fitting is installed, set the squeezing ring on top of the fitting and screw the nut. The nut should be tightly clamped by the wrench.
In this way, all fittings and pipes are installed in a single system of pipes.
One of the advantages of metal -plastic pipes is the simplicity of their installation, and everyone can master it. aviator
