Description

Aqua-Plus PP-R reducing socket - For reducing the pipe diameter

For all diameters ✓ Drinking water approval ✓ DVGW certified ✓

Our Aqua-Plus PP-R reducing sleeves, like all fittings and pipes of the Aqua-Plus piping system, are made of food-safe, impact-resistant polypropylene random copolymer - PP-R for short. The reducer sockets, which are available on both sides to accommodate a PP-R pipe, are divided into three segments. The two outer segments, correspond to the respective pipe diameter, which vary in size for a reducing socket. The depth of the segments is perfectly matched to the insertion depth of the pipe. In the middle there is a segment with a small separating web that acts as a depth limit for the insertion depth and is designed in such a way that the flow of the pipe connection - apart from the intended reduction in diameter - is not restricted even with a smaller pipe diameter.

The product designation of a reducing joint provides information about the pipes for which the joint can be used. The first number corresponds to the outer diameter of the larger pipe in millimetres, followed by a hyphen (whereby the hyphens here vary from dealer to dealer). The second number defines the outer tube diameter of the thinner tube. Here, too, the dimension is given in millimetres.

Properties of the white PP-R reducing socket

PP-R reducing couplings are used in particular in the domestic installation of drinking water and heating pipes to reduce the pipe diameter of the main line to a smaller diameter for the individual supply lines. Depending on the size of the main pipe and the necessary diameter reduction, different reducers are required. In large installations, several different joints may even be used. For example, to taper the main pipe with each floor instead of laying a pipe with a large pipe diameter from the basement to the upper floor.

Thanks to the production from high-quality polypropylene random copolymer, there are no restrictions with regard to the usability of the pipe system when connecting two pipes with different diameters. Approval for use in drinking water supply applications and as transport pipes in the food industry are essential prerequisites for the usability of PP-R pipe systems, so that all pipes and fittings in the Aqua-Plus PP-R series in white - including the PP-R reducing couplings - have national and international approvals.

Processing of Aqua-Plus PP-R reducing sleeves in white

Reducing couplings are used - as the name suggests - to reduce the diameter in a pipe connection. These are available in various gradations. There are reducing sleeves to the next smaller pipe diameter, as well as reducing sleeves from the largest to the smallest diameter and all variations in between.

Overview of available variants of the reducing sleeves

  • PP-R reducing socket 32/20: PP-R pipe with Ø outside 32mm on PP-R pipe with Ø outside 20mm
  • PP-R reducing socket 32/25: PP-R pipe with Ø outside 32mm on PP-R pipe with Ø outside 25mm
  • PP-R reducing socket 40/20: PP-R pipe with Ø outside 40mm on PP-R pipe with Ø outside 20mm
  • PP-R reducing socket 40/25: PP-R pipe with Ø outside 40mm on PP-R pipe with Ø outside 25mm
  • PP-R reducing socket 40/32: PP-R pipe with Ø outside 40mm on PP-R pipe with Ø outside 32mm

Welding PP-R pipes and reducing sockets works in the same way as creating welded joints with simple sockets. Here, too, it is necessary to heat both components at the same time with the socket welder. However, care should be taken here to ensure that the pipe and the socket with the same diameter are placed on the heating mandrel or in the heating socket. With most socket heaters, it is impossible to mix them up, so that only matching elements to one side of the heater can be heated. After the heating time has elapsed, which varies depending on the diameter, the pipe can be inserted into the corresponding side of the reducing socket until the insertion depth is reached. This should be done immediately after heating, straight and without twisting the pipe. Reliable tightness of the welded joint can only be guaranteed with a maximum axial deviation of three degrees.

The welding of pipes and reducing joints depends on the diameter of the pipe. The larger the diameter, the longer the heating and cooling times, as well as the insertion depths of the pipe in the socket. We have summarised this information in separate data sheets with helpful tables on assembly distances, linear expansion and pressure resistance for each pipe diameter separately. These data sheets can be downloaded from the Downloads tab on the Product page for our white Aqua-Plus PP-R pipes.

WARNING: Without heating, the PP-R pipes cannot be inserted into the corresponding side of the PP-R reducing socket. Only when the plastic of the pipe and the socket have softened sufficiently is it possible to fit them together. This is intentional and does not represent a manufacturing error and is extremely important for a long-lasting, tight welded connection of the two system components.
