PUF PE steel reduced curved side nozzle tees
Prefabricated PUF-insulated steel reduced curved side nozzle tees are PUF-insulated pipeline system elements in protective PE sheath.
The
main distinctive feature thereof is the presence of a steel reducer
to change the tube diameter to a less one (or vice versa).
Identification code review
Russian abbr.: Тройниковое ответвление, Ст20 (ГОСТ 10704-91) 273х7,0 – 219x6,0 – 159x4,5 - 1 - ППУ – ПЭ
English abbr.: steel reduced curved side nozzle tee, St20 (GOST 10704-91) 273х7,0 – 219x6,0 – 159x4,5 - 1 - PUF – PE
The designation consists of the following characters:
1. «St20» is the steel grade;
2. «GOST 10704-91» is the State Standard for steel straight-seam arc-welded tube;
3. «273» is the workpiece tube dia. in mm;
4. «7,0» is the wall thickness of the workpiece tube, in mm;
5. «219» is the dia. of the workpiece tube of the side nozzle in mm;
6. «6,0» is the wall thickness of the side nozzle in mm;
7. «159» is the reduced dia. in mm;
8. «4,5» is the wall thickness of the reducer in mm;
9. «1» is the insulation type;
10. «PUF – PE» stands for PUF insulation and PE protective sheath.
