The widespread use of pressure pipes and fittings made of low-pressure polyethylene (HDPE), manufactured is explained by their high consumer characteristics:
- Corrosion resistance;
- Environmental friendliness – safe for humans and the environment;
- The ability to withstand changes in intrasystem pressure and temperature;
- Electrical insulating properties;
- Low cost;
Polyethylene pipes in the usual design gradually lose strength from exposure to solar ultraviolet radiation, therefore they are mainly used for underground laying:
- Pressure pipelines for drinking and technical water supply;
- Domestic and industrial sewerage;
- Irrigation systems;
Power lines – to protect electrical cables from moisture and mechanical damage.
For open laying, pipes and fittings made of light-stabilized polyethylene are used. Its composition includes special additives for protection against ultraviolet radiation, which affects the cost of products.
What pipes and HDPE fittings to choose for water supply
The main technical parameters are the maximum water pressure and the diameter of the pipeline, on which the throughput depends. In household drinking water supply systems, HDPE pipes with a diameter of 20 to 40 mm are used. They are marked with a blue longitudinal stripe and are supplied rolled in coils. Technical ones are solid black with no colored markers.
The design of detachable compression fittings simplifies the installation of pipelines as much as possible – clamping nuts with large ribs are convenient to tighten even by hand. A special plastic wrench facilitates tightening or unscrewing due to the tight grip of the nut.
Lightweight, durable and reliable low-pressure polyethylene pipes are a practical choice of material for plumbing. Most often, a compression or electric-welded method is used to assemble a pipeline. In both cases, HDPE pipe fittings are required. A variety of connector options are available from UNIPUMP. The catalog contains a large selection of HDPE fittings for plumbing and irrigation systems.
Simple and reliable installation
In low-pressure systems, the pipes are connected by screwing on the HDPE compression nut of the fitting. This approach does not require professional installation equipment. To ensure the strength and reliability of the connection, you need to use parts that:
- Have tightness;
- Withstand high fluid temperature and pressure;
- Characterized by a long service life.
For HDPE pipes installed in irrigation and water supply systems, the UNIPUMP brand fitting is optimal. It is made of lightweight but durable polypropylene, withstands water temperatures up to + 45 ° C, and a pressure of 16 bar.
Advantages of HDPE fittings:
- Retain their geometry during operation;
- Stable bandwidth;
- Ease of installation;
- Temperature drops are not terrible;
- Are not afraid of aggressive environmental influences;
Do not rust, do not oxidize.
The fittings offered by HDPE fittings Malaysia are reliable and high-tech, which guarantees successful application in various fields. On our website you can find compression, welded, brass and electrofusion fittings for HDPE pipes.
When choosing fittings, first of all pay attention to the shape and number of outlets. The diameter of the fittings must be matched to the cross-section of the pipes. If the fittings have the same outlet diameters, such products are necessary to connect pipes with the same cross-section, if a transition from one diameter to another is required, an element with different output dimensions is needed, and so on, depending on the connection diagram. Our experts will always help you choose the fittings exactly according to your project.
