PE Pipe & Fittings

PE pipes as water pipelines for garden irrigation

Depending on the water requirement and the respective flow rate, you can use PE pipes with different diameters. The following table shows the dimensions in millimetres and inches. In addition to the required length of the pipe material, pay attention to these parameters when choosing a pipe:

Specifications with dimensions of PE pipe systems

• external diameter 24 mm (PE pipe Blu-Lock push-fitting system, max. 1.8 m³/h)
• external diameter 25 mm (PE pipe ¾", max 1.8 m³/h)
• external diameter 32 mm (PE pipe 1", max 3 m³/h )
• pressure resistance (PN10 - PN16 or PN4 - PN6)

Simply search our website for the PE pipe that suits you best. You can use the technical data in the product description to compare the pipes' specifications. The goods are shipped as roll by DHL.

Specifications with types of PE pipe systems and their use

• UV resistance (use only black PE pipe for above-ground installation)
• PE pipes for drinking water / service water
• PE HD pipes (pipes for drinking water, PE 100 RC) are more rigid; designed for a wider temperature range and higher water pressure
• PE LD pipes (PE pipes for domestic water installations) are more flexible and designed for lower pressures
• Permanent pressure pipes in front of the valves should be set at PN 12.5 bar or PN 16 bar
• Main line behind the valves can be installed with PN 6 bar or PN 4 bar

Our Blu-Lock push-fitting system, the revolution in irrigation installation!

Simply insert the PE pipe into the metal claw of the fitting - the connection is tight & firm! For water pipes that are permanently under pressure, we recommend the installation with pressure fittings. Starting from the valve distribution, we recommend the installation with the Blu-Lock 24 mm system. The Blu-Lock fitting system is much faster and more secure to install than conventional PE pressure fittings. The patented Blu-Lock fittings guarantee an easy, secure and quick installation. This makes it much easier to assemble your system and minimises potential sources of error during installation.

Our professional tip

Be sure to use pressure-resistant pressure fittings in front of the valve box. As a rule, pressure fittings are very pressure-stable and can be used for the installation of cold water pipes. The installation involves several steps and must be carried out meticulously to ensure that the connection is tight:

• First, the pressure fitting is screwed open and the clamping sleeve and the screw coupling are pushed onto the PE pipe cut at right angles (90 degrees).
• The PE pipe is now pushed over the internal O-ring into the fitting as far as it will go.
• The clamping sleeve is then pushed onto the fitting and fixed with the screw coupling.
• Important! Before filling in the trench, you must always carry out a pressure test to check whether the connection is tight.

Why use PE pipe for irrigation installations when it is actually manufactured as drinking water supply?

The installation of drinking water pipes is regulated by DIN EN12201 and the DVGW. Drinking water pipes in PE 100 or PE 100 RC quality made of HDPE plastic are used for this purpose. Since these pipes are produced in large quantities, the availability and supply of this material is high. Even though the specifications of these pipes, which actually replace the use of metal pipes in drinking water supply, are somewhat over the top, the installation of PE 100 pipes is quite common. Only in agriculture, where weight also plays a role in installation, pressure pipe with PN4 or PN6 is usually used instead of PE HD pipe.

Use of PE 100 RC pipes - PE plastic drinking water pipe

PE pipes are plastic pipes used for the supply and disposal of drinking water. They are also used for watering gardens and in agriculture. PE pipes are made of polyethylene (PE) and have a diameter of 16 to 63 millimetres. They are supplied in rolls of 25 metres, 50 metres or 100 metres in length for easy shipping. PE pressure pipe is suitable for an operating pressure of up to 16 bar, depending on the wall thickness and specifications. Pipes made of polyethylene have a very long operating life and are resistant to acids, alkalis and saline solutions. DIN8062 or DVGW Article 7 are often quoted for PE pipes by the manufacturer, as PE is extremely resistant to pressure and temperature.

Laying pipes with pressure fittings: water technology and properties

PE fittings are available in sizes from 16 mm to 63 mm. PE pressure fittings are the best solution for connecting PE pipes. Metal fittings can also be used, but they must not come into contact with the drinking water. When installing PE piping systems, elbows, couplings and T-pieces may be required. PE pipes and fittings are best suited for installations where a high degree of resistance to external influences is required (e.g. weather). PE is also permanently form-stable and is therefore ideal for long-term use in piping systems. Pipe clamps are often used to connect PE pipes and fittings in areas with high working pressure or high temperatures. Fittings made of polypropylene can also be used, but should be carefully monitored at higher temperatures as they can become brittle if not used properly. When installing PE piping systems, particular attention should be paid to the type of pipes used and the intended use.

We will be happy to answer any questions you may have about your project or about shipping. Compare the specifications and find the right manufacturer for the installation of your garden irrigation system.
Even though the pipes are usually laid in a trench, pressure fittings and pipes are UV-resistant. An above-ground installation is therefore possible by all means.
