Bogenn PP-R Composite Pipes are used for the transportation of hot and cold liquids. Low thermal coefficient of expansion, smooth inner surface, high chemical resistance, conformity with hygienic requirements are some of the most remarkable features of the system.    

Bogenn PP-R Composite Pipes consist of 3 different layers. These layers are PP-R/PPR-GF/PP-R.
PP-R (Polypropylene Random Copolymer) is on the inner surface of the pipe. This layer, which constitutes the surface on which the liquid transported gets into contact with, not only provides a high chemical resistance, but also creates a smooth inner surface.  
PPR-GF (Polypropylene Random Copolymer – Glass Fiber) layer is produced with a special raw material that is composed of the combination of high resistance glass fiber with polypropylene raw material (compounding). Thermal coefficient of expansion is reduced to the value of 0.45 mm/m °K thanks to PPR-GD raw material with a low elongation coefficient.
Outer surface of the pipe consists of PP-R layer. In addition to its impact resistance, which complies with the standards, PP-R layer is also compatible with socket welding method.
The production of Bogenn PP-R Composite Pipes is based on the following standards.
TS 13715 Glass Fiber Reinforced Multi-Layer Polypropylene Pipes
TSE K 25 Glass Fiber Reinforced Multi-Layer Polypropylene Pipes
DIN EN ISO 15874 Plastic Piping Systems
DIN 8077/88 Polypropylene Pipes
Bogenn PP-R Composite Pipes are produced within Ø20 – 110 mm range with the specifications given below. The length of the pipes is 4 meter and can be tailored according to the special requests of the customers.
Bogenn PP-R Composite Pipes are produced in white and green colours. Outer layer of pipes produced for projects requiring UV resistance is black.
Bogenn PP-R Composite Pipes and Fittings are used for the transportation of cold and hot liquids within buildings.
According to DIN EN ISO 15874 standard, Bogenn PP-R Composite Pipes are used in the following application classes and rated pressures.
Conditions of use for Class – 1 and Class – 2 pipes are described below.
BOGENN PP-R Composite Pipes and Fittings are connected with socket (or fusion) weld method. Directives and standards of our company must be taken into consideration for implementing the connection method accurately. Standards applied and recognized in socket weld method are DVS standards.
Due to the differences in production process, PP-R fittings are not manufactured with 3 layers like the pipes. Since thermal expansion of fittings are in negligible sizes in the installations, they do not need to be manufactured in a composite structure as technical requirement like the pipes.
Our company provides all kinds of components (sleeve, elbow, threaded transition pieces etc.) required for the installation to its customers.
Criteria and applicable national legislations must be complied with in the transportation, storage and installation of Bogenn PP-R Composite Pipe and Fittings.
- Bogenn PP-R Composite Pipes must not be subject to any impacts during transportation, storage and installation. Impact resistance of PP-R raw material decrease particularly at weather conditions of  0 °C and under. Necessary measures must be taken in order to prevent pipes and fittings from being subject to impacts.
- Bogenn PP-R Composite Pipes are not resistant to UV (ultraviolet) rays. Necessary measures must be taken for long periods of storage and applications in which the pipes may be subject to sunlight. 
- Requirements of the applicable legislation must be taken into account when socket weld method is applied for the connection of Bogenn PP-R Composite Pipes. Where ambient temperature is 5 °C and less, socket weld application must be avoided, and welding operation must be resumed after necessary measures are taken.
- Thermal expansions expected in the installation must be calculated and necessary measures must be taken accordingly. 
- Measures must be taken for preventing possible damages in the pipes as a result of excessively high pressures and cases in which the fluid in the installation freeze.
- After the installation procedures are completed, the piping systems must be subject to pressure test and results of the test must be recorded.
- Additional measures must be taken to prevent possible damages on the completed piping system as a result of other ongoing construction works.
