TYTAN Gas pipes
High-density polyethylene, abbreviated as PE-HD, is used to manufacture segmental pipes and fittings. It is a raw material that works well in many pipe applications. It is characterised by high resistance to impact loads that can occur during pipe-laying and a wide range of operating temperatures that allow work to be carried out at any time of the year.
The subject of the presentation are PE 100 single-layer pipes and TYTAN PE/PE and TYTAN PE/PP single- or double-layer pipes made of polyethylene PE 100-RC and polypropylene (PP) intended for pressure pipes (waterworks, gas fuels, pressure and vacuum sewers) and gravity pipes (sanitary sewerage systems, drainage), as well as for making culverts under road banks laid underground in the roadway.
The TYTAN system consists of:
- Type 1 (one layer) - Polyethylene PE 100, PE 100-RC
- Type 2/2 (two layers) - PE 100-RC polyethylene pipe
- Type 2/3 (three layers) - Polyethylene pipe PE 100-RC
- Type 3 (two layers) - PE 100-RC polyethylene pipe with an additional outer protective layer of PP
- Type 3 PLUS (two layers) - In addition to the protective layer as in the third type, it also has a detector insert that facilitates maintenance of the pipeline.
Tests of TYTAN pipes carried out at HESSEL Ingenieurtechnik GmbH and at the Oil and Gas Institute in Krakow confirm that they are resistant to scratches and point loads that can occur when building the network at home without using ballast and backfill and when building and renovating the network using traditional methods and excavation.
Pipe sections depending on diameter and purpose can be combined using the following methods:
- Butt welding
- Welding using electrofusion fittings
- Connection using clamps
Purpose of the programme
They are intended, among other things, for the construction of water supply networks, sewerage networks and for the transport of aggressive liquids.
- For the transfer of gaseous fuels.
- For the installation of gas networks.
