Banded pipes in polyurethane foam insulation
Banded pipes in polyurethane foam insulation consist of a steel pipe with a polyurethane foam layer and a polyethylene sheaths reinforced with bands for routing network sections in cases.
The reinforced polyurethane foam pipe is more resistant to mechanical damage and deformation, which allows extending the overall service life.
Identification code review
Pipe St 09G2S (GOST 8732-78) 57 х 3.5 – 1 – PUF – PE – B
Let’s review the symbols for marking the PUF B pipe:
1. 09G2S – steel grade;;
2. GOST 8732-78 – Seamless hot-deformed steel pipes;
3. 57 mm – pipe diameter;
4. 3.5 mm – pipe wall thickness;
5. 1 – insulation type;
6. B – availability of band.
7. PUF – PE – polyethylene foam insulation, protective sheaths from polyethylene.
Band width, case pitch and size can be adjusted according to project requirements.
We will manufacture and deliver custom-made banded pipes with plugs and a lead-out cable for Rapid Remote Control System.

Application
The banded PUF PE pipes are used for installation of underground pipeline systems in areas with increased impact on the ground – highways, railways, etc. The band ensures additional protection against mechanical damage during duct-free laying: the PUF PE pipe is protected from ground movement, which is important due to a limited access to the pipeline.
