PUF PE steel curved side nozzle tees
Prefabricated PUF-insulated steel curved side nozzle tees with protective PE sheath are parts of piping systems with a curved side nozzle in perpendicular plane to the main pipe section axis. Steel workpieces are covered with PUR foam as insulation and a PE layer for longevity and protection against mechanical impacts.
Identification code review
Russian abbr.: Тройниковое ответвление, Ст20 (ГОСТ 8732-78) 273 х 8,0 - 1 - ППУ – ПЭ
English abbr.: Curved side nozzle tees, St20 (GOST 8732-78) 273 х 8,0 - 1 - PUF – PE
The designation consists of the following characters:
1. «St20» is the steel grade;
2. «GOST 8732-78» is the State Standard for steel seamless hot-milled tube;
3. «273» is the workpiece tube dia. in mm;
4. «8,0» is the wall thickness of the workpiece tube, in mm;
5. «1» is the insulation type;
6. «PUF – PE» stands for PUF insulation and PE protective sheath.
