Quadrangular straight piping are produced up to a standard length of 1500 mm, but the length can be adjusted after agreement with the customer. Ventilation connections are done using flanges – loose flanges, fixed flanges.
Dimensions of quadrangular and circular piping are produced in a dimensional series according to a ČSN EN 1220 (120506) legislation.
The circular pipe is purchased up to dia. 800 mm, we manufacture larger sizes ourselves.

Example of marking:

PPC 355×355/1500/P40-PP/PP-H RAL 7032

quadrangular direct piping, dimension 355×355 mm, lenght 1500 mm, type of connection fixed flange, material PP-H (polypropylen homopolymer) colour design grey

Implementation:

The material is selected according to the type of medium that flows through the given fitting and also the environment in which it is located.
The type of connection is possible via a fixed flange (PP). Connection with loose flange (VP) is possible, where during implementation the flange will be welded on site with wire.
According to the customer’s wishes, it is possible to combine these connections.
The maximum aspect ratio is 1:4. If the ratio cannot be executed, the ventilation ducts must be reinforced. Reinforcement is also necessary at higher pressure loads of the pipeline network.

Maximum and minimum temperature of the medium depending on the material used:

PP-H: from 0 to +100 °C
PP-C: from -30 to +100 °C
PVC-U: from 0 to +60 °C
PE-HD: from-50 to +80 °C
PE100: from -50 to +80 °C

Note: temperature depends on pressure and type of medium.

Implementation:

The material is selected according to the type of medium that flows through the given fitting and also the environment in which it is located.
The type of connection is possible via a fixed flange (PP). Connection with loose flange (VP) is possible, where during implementation the flange will be welded on site with wire. Furthermore, it is possible to connect the circular pipe using a hem (LS).
According to the customer’s wishes, it is possible to combine these connections.
