From time to time the owner of the house or cottagethe seemingly not so difficult is solved, but in fact a difficult task - inserting a pipe into a pipe. It is important to fulfill two conditions: preserve the integrity of this section of the pipeline and not disrupt its hydraulic mode, whether it is the installation of a meter or filter, the connection of a household appliance (washing machine or dishwasher), water withdrawal from the water supply system.
The problem is solved in several ways, depending on where the place of tie-in should be located, from laying pipes, etc.
In private houses and country cottages, where twoor several floors, a multitude of residential and utility rooms, the tie-in into the water pipe is replaced by connecting a collector to it. It has several outlets to which you can connect without any tie-in either the required pipe or water intake hoses for household appliances. This is the most rational decision in those rooms where a large water intake is planned.
If only one tap is needed, into the pipetee inserted. But everything becomes more complicated if there is no unwinding joint in the place where the tube should be inserted into the pipe. We'll have to very accurately cut a section of the pipe under the tee and also brew it at the ends with high quality. Even worse, if the pipe is almost closely adjacent to the wall or even half walled up.
Не меньший объем проблем и с пластиковыми трубами:It is necessary to replace the pipeline segment with two small pruning plus a segment with a pipe to which the new pipe is connected. Is it really impossible to crash into a pipe without cutting it? Can. And almost any.
Потребуется вышеупомянутый отрезок с патрубком, but it must be cut along the main pipe so that the flange fits tightly to the pipe into which it is cut. It should tightly cover this pipe in the place of the upcoming incision, securely covering it. In this place, you need to drill a hole equal in diameter to the nozzle. Place around the hole, not reaching its edge 1 cm, and the entire inner surface of the flange are lubricated with non-sealing sealant. Then the flange is superimposed in place of the cut-in and tightened at the edges with hose clamps until an extruded sealant appears at the edges of the flange (it is removed). If the pressure in the pipe is small, the flange can be attached to it by wrapping a wide electrical tape. Such insertion of a pipe into a plastic pipe can be performed by any home craftsman.
But if the pipe to crash into,made of metal, the flange with the pipe, most likely, will have to do it yourself. The fact is that the internal diameter of the pipe under the flange must be equal to the external diameter of the pipe to be inserted. This will provide a minimum gap between the surface of the pipe and the bottom of the flange. But after its manufacture, in this case, it is necessary to drill a hole of the required diameter in it and weld the corresponding branch pipe to it.
Its features are in the mounting flange topipe, especially if you are inset in the cast iron pipe. In some cases, it is almost impossible to use welding for this. You have to replace it with the already mentioned non-sealing sealant and clamps. If the pipeline is used to transport technical water, you can apply epoxy, but in this case it will be necessary to exclude its contact with water. This is achieved by making a thin strip of rubber bandage. After the connection is made, it is highly advisable not to remove the clamps - for warranty.
Thus, a pipe can be inserted into the pipe of almost any purpose - plumbing, heating, sewage.
By the way, with a metal flange (only without a nozzle) in a similar way you can close up the fistula formed on the pipe.
