How to connect PVC pipes without a connector

Sometimes you may not have special factory-made couplings at hand, with the help of which plastic pipes, including PVC, of ​​the same or different diameters are quickly, reliably and hermetically connected.
Moreover, it does not matter for what medium the pipeline is intended: for water, gas, wastewater or for other purposes, as well as their diameter: it can be small, medium or very large.

To work in this case, you will only need plastic pipes, couplings, a tube of special glue and initial skills in handling products made from this material.

Connecting plastic pipes using couplings


The work is performed in the following sequence:
1. The ends of the pipes to be connected are cut perpendicular to the axis of the product, and a small chamfer is removed from them so that during final assembly the ends of the pipes do not scrape off the applied glue from the inner wall of the coupling.

2. The pipes to be connected are inserted into the coupling from both sides until their ends touch approximately in the middle of the connecting piece, and marks are placed on them indicating the depth of the pipe entry into the coupling.
3.The surface of the pipes from end to mark is covered with a special glue, which also has sealing properties. It is also necessary to lubricate the inner surface of the coupling.
4. Then the pipes coated with glue are reinserted into the coupling until they stop against each other and are turned in opposite directions by 90 degrees for a more uniform distribution of the adhesive composition over the surfaces being connected.

5. The assembly assembled with glue must be left alone for the time specified in the instructions for using the adhesive. Usually it is 10-15 minutes. It is better to use the pipeline 24 hours after completion of the connection work.

Connecting plastic pipes without couplings


In this case, it is necessary to make a socket on one of the pipes being connected, using a hair dryer (heat gun) to soften the plastic and a second pipe to form an expansion.
The process is performed in the following order:
How to connect PVC pipes without a connector

1. Using a hair dryer, the end part of one of the pipes being connected is uniformly heated to a length approximately approximately the diameter of the pipe. In this case, it is necessary to periodically monitor the degree of softening of the plastic so that, on the one hand, it is not hard, and on the other, it does not melt or flow.

2. When optimal plasticity is achieved, continuing to maintain this state with a heat gun, the second pipe is inserted into the first and by rotating at an angle and longitudinal movement mainly inside the heated pipe, a socket is formed. When the socket length reaches approximately the diameter of the pipe, the heat gun can be turned off.

3.While the heated pipe has not yet cooled down, by rotating the second pipe in one direction or the other and applying longitudinal force mainly inward, it is necessary to continue forming the socket until the plastic has completely cooled.

4. Then, the pipe forming the socket is pulled out. Its inlet section and the inner surface of the bell are degreased, lubricated with sealing glue and reassembled.

Such a permanent connection, if it is made with high quality, especially in terms of maintaining the heating temperature regime, is in no way inferior to connecting pipes using special couplings.

    What kind of "heat gun"?? This is an ordinary construction hairdryer..

    Imagine that you have an object and kilometers of pipes, how long will it take for these shamanic dances with a tambourine around each connection? And with a coupling, and an extremely cheap one, it will take about five minutes to do everything...Well, maybe for yourself, where if it leaks it won’t be a big deal... Although it’s still a controversial decision

      I am personally shocked by such commentators! What kilometers, why are you talking nonsense? This is a site for do-it-yourselfers to find a way out of the current situation. For 1-2 times this is a super master class. Thanks to the Author!

        For one or two times, go get a special glue for PVC pipes, and pay - a tube for a pair of such joints costs as much as several couplings

    It’s a pointless, unjustified exercise, after all, they sell special connecting couplings and they cost pennies and the connection is more reliable. I’ve used them more than once when a pipe was broken while digging with a shovel.

      “Sometimes you may not have special factory-made couplings at hand, with the help of which plastic pipes are quickly, reliably and hermetically connected” - I haven’t read the article, but I condemn it?

      Yuri Vasilyevich, at least don’t embarrass yourself, you were told that this is not a standard measure for those who find themselves in an extreme situation - the store is far away, there is no time to run, but work needs to be done. This does not mean at all that this method is correct and intended for such connections. But in extreme cases it’s quite effective, I’ve convinced myself, I promise)))

        I agree with you if this is an extreme measure and it will be a temporary thing for now or the pipe will be used for some kind of crafts. Acrylic, well, don’t accustom yourself to such an attitude towards work, especially if you take on a part-time job. Not everyone likes words anyway, especially when you have to redo them After such masters, just believe it.

    This is only possible on thin (low-pressure) pipes produced in household appliances. This won't work on GF. And if there is not only water inside the pipe...

    One can only be happy for the author, there is nowhere to buy a coupling, but there is a special glue for pipes, which costs a decent amount and is not sold everywhere.

    There are no couplings and nowhere to get them, tundra all around. Another thing is special. glue and industrial hair dryer. Here they are. Always at hand. Rave.

    My father-in-law did such crap. Leaks from all connections. Everywhere there are jars under the connections to collect water...
    Great article!

    Sealing glue!!! What a word :) Can you be more specific. The following brands of glue are used for PVC.

    Wrap the joint with tape and that's it
