What is compression fittings for hdpe pipes - purpose and

If you decide to equip the sewer system of polypropylene products, then you may have to deal with such a thing as a fitting for pipes. Of course, it is unlikely that this element of the pipeline will be needed when connecting a sink or shower cabin in an apartment, but when laying systems in country houses they are very useful. We will try to give you as much useful information as possible about the above-mentioned compression fittings.

Introduction to the material

Compression fittings for polypropylene pipes are used directly for the tight connection of sewage elements of different diameters. This allows you to bypass problem areas and increase the length of the pipeline, which allows you to make small savings in the workflow.

Note! Fittings are suitable for both the drinking system and the installation of drain systems.

It should be noted that the material used for the manufacture of such parts usually serves as:

• Stainless steel.
• Cast iron.
• Copper.
• Brass.

The base material as a whole influences the scope of application of this connecting element (for example, there are separate compression fittings for copper pipes), as well as its cost. At the same time, the price of the compression part is much lower than the option of connecting pipes by welding or glue.

As for the allowable diameters for products of this kind, they range from a minimum of 16 mm to 110 mm. The small size suggests high strength, organizations producing compression fittings for metal pipes claim that the maximum allowable pressure is 16 atmospheres.

As you understand, such indicators are almost impossible at home, in turn, this means a long service life and reduces the need for repairs.

What is the "compress"

There are five main components that make up the fitting:

• The body is a durable sheath that protects the compound from damage and various chemical influences.
• O-ring - is responsible for the tightness of the connection, to avoid leakage in hard to reach places.
• Clamping ring.
• The pressing sleeve fixes the ring. If the defect in the production is allowed in this element, the connection will not be so reliable.
• Cover - nut, which is sealed outside

Note! Also important is the correct installation of compression fittings for HDPE pipes, it is he who is responsible for the reliability and durability of the connection. In fact, all the work can be done by hand, a special skill is not required here, as, in fact, a special tool.

It is enough to get an adjustable wrench and a hacksaw for the material from which the pipeline is being laid.

The advantage of fittings

Now let us touch directly on the moment because of which the parts we describe are used and are very popular in certain areas:

• As we have said, compression products have high strength and resistance to high pressure. Of course, it would be wrong to say that it is impossible to damage them mechanically, but this already applies to vandalism, in a living environment it is impossible to damage the fitting.

Note! You can talk about the resilience of various chemicals and anti-corrosion, which has a positive effect on the operational life of the product. It is only necessary to ensure that those solutions that are "afraid" of the materials used in the manufacture of the elements of the connection are not in contact and do not flow through the pipeline.

• Also, the products are not afraid of temperature changes, long-term freezing, which allows the possibility of their use in laying pipes under the ground or in concrete.
• Once fixed products no longer require quarterly inspection or suspenders.
• An undeniable plus - compression fittings for steel pipes, or for other materials, can be used for unsuited joints. Thus, metal-plastic and steel products, polypropylene with copper, etc. are easily joined.

Installation steps

Below is a brief instruction on how the compression fitting is attached to the pipeline:

• Stage One - preparatory work. The edges of the pipes should be cleaned and have the most even cut, with regard to the details of the connection, it should be inspected: the slightest traces of damage may indicate a violation of quality. In this case, it is better to replace it.
• Stage Two - laying pipes. It is necessary to begin the installation of the sewer system, measuring out in what places the connection of the HDPE pipe will be located by compression fittings. You should not condescend to millimeter alignment, it is enough to place the elements all over with a small margin that can be trimmed.
• Stage Three - installation. The ends of the pipes are inserted into the fitting, the nut is manually tightened until the joint becomes rigid, and then it is reached with a key.

  Note! Pipes should be at the angle that is caused by the product, try to bend and fix the connection in a position where it is under pressure and voltage is not recommended.

Conclusion

As you can see, the above described element of the pipeline takes place not only in a professional environment, but also applicable for private use. The most important thing is that you can fix the item without extra costs and hassle, as we have said, it is enough to get the key of the desired size.
