The white Aqua-Plus PP-R T-reducers are available in a very wide range of designs for all conceivable pipe connections with additional branching. From a single reduction of the pipe diameter, to a double reduction with the same pipe diameter, to three different sizes. For PP-R pipes with diameters from 20mm to 40mm, there are many variations, from reductions to the next smaller diameter to reductions from the largest to the smallest pipe diameter.
In order to be able to see at a glance which pipe diameters must be used for the specific receptacle of the T-reducer, these are indicated in a specific order. The indications, for example for the PP-R T-reducer 32/25/20, mean that the lower receptacle with a diameter of 32mm is suitable for PP-R pipes of the same diameter. The second digit defines the pipe diameter of the branch. The last number, on the other hand, defines the outer diameter of the pipe to the opposite side of the first, thicker pipe. The diameter reduction does not always occur at the branch. The T-reducer 25/25/20 is a good example where one side and the branch are suitable for 25mm pipes and a thinner 20mm pipe has to be inserted into the third straight socket.
The Aqua-Plus system made of polypropylene random copolymer is equally suitable for the supply of drinking water and as a transport pipe for cold and hot water up to 95°C. This makes the pipe system ideal for heating systems, heat pumps and geothermal systems. This makes the pipe system ideal for heating systems, heat pumps and geothermal energy. While pipes with an outer diameter of 32mm or 40mm are usually only used for the main lines, only a 20mm pipe is usually used for wall connections, bathroom fittings or individual radiators. So that these can branch off from the main pipe, T-pieces with diameter reduction are necessary. The so-called PP-R T-reducers, which are used for welding the PP-R pipes, meet these requirements so that the branching and the reduction of the pipe diameter can be implemented in one work step.
Pipe systems for drinking water supply are subject to strict requirements, which are defined by DIN or EN standards. Our Aqua-Plus PP-R system fulfils all the necessary standards and also relevant certifications at national and international level, such as the DVGW certificate or the SKZ certificate, which are important for the use of the pipes and fittings as drinking water pipes in Germany.
To limit the insertion depth, as well as to optimise the flow resistance, the receptacles are limited in depth, so that in the inner area of the T-reducer the diameter is matched to the inner diameter of the pipes. Another advantage of this special design is that the flow causes significantly less noise when reducing or branching off than with comparable products whose inner diameter is not optimally matched to the pipes.
To ensure that reducing T-pieces can be used as transport pipes in the chemical processing industry as well as in the food industry without restrictions, they are also made of chemical-resistant, impact-resistant polypropylene, which is a food-safe plastic.
A T-piece functions as a pipe connector with an additional branch for a third pipe, which are permanently connected by welding. This is also the case with a T-reducer, but here the pipe diameter is reduced for one or more receptacles. Due to the various combination possibilities, there is a great variety of products available for branching the piping system. The following list is intended to provide a quick overview of the available variants.
When welding, it is important that the pipe and the adapter are heated at the same time. Due to the different diameters, you have to make sure that you do not mix up the diameters and heat the same sizes. With most pipe welders, however, confusion is impossible because the heating mandrel and the heating socket are located on one side of the heating bush each. For easy handling when welding the three pipes with the T-piece, we recommend welding the two pipes opposite each other first and then the branching pipe. This way you are not hindered so much by the finished pipe connections when putting the T-piece onto the heating mandrel.
The different pipe diameters used for T-reducers each require different heating times to soften pipes and T-pieces for welding. The resting times for cooling the welded joint also depend on the diameter of the pipes. On the product page for our white Aqua-Plus PP-R pipes we have summarised the relevant parameters for each diameter separately in an installation data sheet. These data sheets also provide helpful information on the installation of the pipelines and can be downloaded in the data sheets tab.
WARNING: Compact, strong connections are necessary for tight welded joints of the PP-R pipe system. This is achieved, among other things, by a smaller diameter of the pipe receptacles of the T-reducer, which is half a millimetre smaller than the pipe outer diameter. This means that the pipes cannot be inserted into the receptacle of the T-piece without prior heating on the pipe welder.
NOTE: The PP-R T-reducers are suitable for branching pipe systems with simultaneous reduction of the diameter of one or two pipes. The reducer tees are not suitable for branching pipes with identical diameters. Use the simple PP-R tees from our shop instead.
