Production program Peštan PP SPIROPIPE spiral pipes for large sewer systems or non-critical transport of water includes pipes made of the highest quality polypropylene with profiled reinforcement in the ribs, in diameters of Ø300 up to Ø1200, and in the coming period we will start the production of pipes in diameters to Ø3000.

Also, these pipes are produced in standard length of 6m. They can also be produced in other lengths, according to project specification.

Peštan PP SPIROPIPE spiral pipes are produced in more variants of strength/resistance to the external load (depending on the step of the profiled outer layer for reinforcement as well as depending on diameter):

SN 2 KN/m²

SN 4 KN/m²

SN 8 KN/m²

SN 12.5 KN/m²

SN 16 KN/m²

Application and installation

Inner diameter and hydraulic characteristics of Peštan PP SPIROPIPE spiral pipes remain the same over the time, regardless of the type of the profile, thanks to the strong reduced roughness and low adhesion of the inner pipe walls. The nominal diameter corresponds to the effective inner diameter of the pipe, with tolerances allowed according to reference standards.

Connection of the PP SPIROPIPE

Peštan PP SPIROPIPE spiral pipes are connected only over the socket into which the EPDM rubber is mounted, which means that unlike PE Spiropipe, these cannot connect with electrofusion.
This type of connection is most widespread due to its own simplicity and low production time. At the female’s end of pipe, the rubber was inserted during the production and it is homogeneously coupled with a muff. The male and female parts of the connection are performed in accordance with the parameters by the EN standard 13476.

The rubber is made in accordance with EN 681-1.

Types of profiles
Peštan currently offers three basic pipe profile products to its customers:

1. Peštan Spiro PR
2. Peštan Spiro CPR
3. Peštan Spiro OP

* Spiro PR is in standard production, while other two are on buyer’s demand.
