PUF PE parallel steel tees
Prefabricated PUF-insulated parallel steel tees (h-tees) in protective PE sheath adopt parallel side nozzle shape with PUF insulation and protective PE sheath.
Identification code review
Russian abbr.: Тройник параллельный, Ст20 (ГОСТ 10704-91) 325 х 8,0 – 219 x 6,0 - 1 - ППУ – ПЭ
English abbr.: Parallel tee, St20 (GOST 10704-91) 325 х 8,0 – 219 x 6,0 - 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. «325» is the workpiece tube dia. in mm;
4. «8,0» is the wall thickness of the workpiece tube, in mm;
5. «219» is the tube dia. in mm of the workpiece tube of the side nozzle;
6. «6,0» is the wall thickness of the workpiece tube of the side nozzle, mm;
7. «1» is the insulation type;
8. «PUF – PE» stands for PUF insulation and PE protective sheath.
By default, the manufacturing may use tees and bends bigger by 1...2 mm than the main tubes.
