It is impossible to make plumbing wiring or connect a washing machine without correctly selected accessories. We will tell you how to choose steam fittings malaysia for polypropylene pipes in this article.
Fitting And Its Types
In simple terms, shaped parts help to turn a simple polypropylene pipe into a real pipeline system: connect to each other, change the direction of the pipe, and make wiring.
There Are Several Types Of Fittings:
Coupling – for connecting two pipes of equal diameter. It is used in long sections, since the pipes themselves have a finite length.
The corner is a further development of the clutch. Changes the direction of the polypropylene pipeline to 90 0 or 45 0 .
Adapter – designed to connect pipes of different diameters. Outwardly it resembles a clutch, but with different sizes at both ends.
Tee – serves for joining three pipes at the same time. There are tees that can do this in one plane (the simplest subspecies), and in different ones, when each pipe lies at a certain angle to the others.
Cross – connects four pipes. Just like tees, they can connect pipes not only in one plane, but also in two.
Bypass, it is also a compensator. It has two functions: bypassing the already laid pipeline and compensating for the linear expansion of polypropylene pipes – by the way, their biggest drawback. There are both short and long contours (they differ only in the radius of curvature of the contour).
Plug. At some point in the plumbing installation, it may be necessary to close the pipe opening. This is what the stub is used for.
Combined fitting. Serves for transition from a polypropylene pipe to a threaded connection. There are both completely plastic and with a metal part. The latter are usually called fondly “American”.
Collector. A real monster with multiple inputs and outputs. Designed to distribute liquid streams. We can say that the manifold is the control unit of the pipeline system.
A separate view can be mentioned corners, tees and crosses, in which there are different sizes of nozzles. They are called transitional, and their function remains the same, but polypropylene pipes with different diameters are already connected.
This list is not exhaustive, manufacturers produce a much larger range of fittings for polypropylene pipes. These include, for example, parts used to connect plumbing equipment – washing machines, baths, jacuzzis – to the main pipeline.
When the plan of the future system of polypropylene pipes has already been drawn and the number of various components has been calculated, the question arises of which fitting is needed.
There Are 3 Main Types Of Fittings, Differing In Both Material And Type Of Connection:
Compression, including Eurocon;
Crimp press fittings;
Now let’s look at each of them in more detail.
It Can Be Made Of Various Materials:
What matters here is not so much what it is made of, but how the pipes are connected and how they are sealed.
In general, a fitting consists of two large sleeves that are fastened together using a threaded connection. Inside them there are special crimping rings, which, when the bushings are connected, compress the pipe, as if flattening it. Rubber gaskets, also inside, provide additional sealing of the connection.
