Steel pipe PUF in a galvanized sheaths
PUF steel pipe in a galvanized sheaths is a steel pipe with a heat-insulating layer from polyurethane foam protected by galvanized sheaths. Pipes in the ZP sheaths are used for above-ground routing of pipeline systems. The metal sheaths extends service life, increases thermal insulation properties and protects against external mechanical damage.
Identification code review
Pipe St 20 (GOST 10704-91) 325 х 7.0 – 2 – PUF – ZP
Let’s review the symbols for marking the PUF ZP GOST pipe:
1. ST 20 – steel grade;
2. GOST 10704-91 – Longitudinal electrically welded steel pipes;
3. 325 mm – pipe diameter;
4. 7.0 mm – pipe wall thickness;
5. 2 – insulation type;
PUF 6. PUF – ZP – polyethylene foam insulation, protective sheaths – zinc plated.
Application
Steel pipes in a galvanized sheaths are mainly used in above-ground routing of heat supply systems, as well as underground: in tunnels, channels, in hot water supply and cold water supply networks. These are:
· in outdoor communications, heat supply systems, heating mains;
· water supply systems;
· industrial communications;
· gas pipelines;;
· oil pipelines.
