This method I came to a head on their own. Without looking to other sources. Perhaps already doing or have done. But before that the method of "dopetril" yourself. Perhaps this way of additional sewer pipe insulation is nonsense... But I still dare and do "a couple" of photos of my "hooliganism."
Explanatory "note"
When assembling a pipeline from polypropylene sewer pipes of different diameters are used a flared connection. The bell has a rubber cuff which performs the function of sealing and fastening pressureless conduit. As practice shows, socket joint in some of these gums tend to "crack" and leak. Or due to thermal expansion or "shock" loads of the drainage pipe can even be disconnected. Therefore it is important to mount special conduit clamps. But sometimes there are important sectors of sewer pipe to which it is difficult or impossible to reach. That's where my method and useful additional fixation.
Process
Dla order to illustrate the process of further isolation, we need pipes and fittings. But first, zagermetiziruem straight section.
Flipping the gallery, there is "clear" picture.TOrum pipes need a suitable plastic bottle. Her we will use as an extra. sealer.
FROMs process is to prepare a suitable length of the bottle. And dressing her up in the flare connection. Flipping.
DIn order that the polyethylene bottle sealed conduit it is necessary to heat the gas burner or hairdryer construction, it is possible and conventional hairdryer, sneaking it from spouses))).
On the the first photo we see the tube from heating is reduced in size. This property is called "Shrinking". Well, then just heated up the rest of the polyethylene.
It is important not missed the process of "overheating" of the pipe itself, otherwise it will "float". This compound was prepared very dense.
Important - with sufficient force to move without pipe socket. That does not violate the mounting technology. Tk during heating and cooling pipe should shift slightly.
The most interesting thing is the sealing parts (fittings), "relief" and difficult process of sealing in this way has its own nuances. Photo Gallery, view them without my comments.
As you have noticed, the connection to the "bends" is difficult to seal because of its topography.
According to the results we have obtained a very tight connection, which can be dismantled without compromising pipeline when needed. Just all the connections in the mobile measure. That does not violate the mounting technology. What do you think about it. Leave a comment.
