Types of plastic pipes

methods bonding metal pipes

When we are paving the pipes, the first thing we have to turn our attention - a reliable connection fitting.The market presents a variety of types of plastic pipes that can be connected without the help of professionals.

Types of connections:

1. With compression fittings.
2. compound such press fittings, with slip-on or crimp coupling.

Connecting with compression fittings

The most important advantage of this compound is that even the most inexperienced person can install them yourself without even using Specialized tools.If problems arise, they can be easily replaced, since this type of communication is considered to be collapsible.

himself fitting includes a cap nut and brass ferrule, as well as a metal fitting, which has two rubber pads.When tightening the nut, the ring is compressed and it gives an excellent and close connection to the fitting.

Also remember that metal produced and stored in rolls, so when you use early in their need to align.It is necessary to pay attention to the end-portions, as an end chamfered with a knife or squaring.Tube is desirable to thread the union nut, the ring, as well as the gable and rubber materials lubricated fitting efirolyu, that is oil.A more advantageous to use a silicone efirol.

End pipe fitting plant for rotational movements.The ring should be pushed onto the socket and only then tighten the union nut.What would be good quality and tighten the screws need to use two keys.

Operation crimp fittings

Different types of plastic pipes constitute the strongest connections with compression fittings it.The connection itself is interpreted not collapsible and is used in order to hide the pipe.

fitting consists of:

1. Fittings with annular shoulder and the seal.
2. crimp sleeve.
3. dielectric spacers.

When you start with a pipe, it is cut off by the size, which is necessary, and only then it is possible to put the crimp sleeve.In this case, we are helped by the expander, because with the help of the pipe end is expanded, and the fitting is inserted very simply following the operation.What would our clutch is easy and without any problems bearing down, use press the tick.We must remember that the diameter is used, which has the diameter of the pipe line.

also on the metal coupling appear parallel bands and it's going to help the electric compression.Some embodiments of the fittings have a crimp sleeve on the body of the fitting.

Applications tension fittings

All kinds of plastic pipes can be connected in tension fittings, and do it in such a way that they were hidden.The method consists in thrusting tight coupling in the portion where the tube is already fitting.This is a non-separable variant for work requiring special equipment: hydraulic or manual press.

At the beginning of the pipeline is put Couplers for that later she could easily push.Using a heat gun or expander expands our end cutting sleeve.With the help of the press, it is coming to an enlarged portion and a connection has not folding, but has a higher reliability.
