Steel elbows PUF PE GOST 30732-2020, short type
A short prefabricated PUR-insulated elbow in PE sheath is a steel elbow in prefab PUR shell, and protective PE sheath with short butt-weld nozzles with 420 mm length and above.
Identification code review
Elbow 90, St 20 (GOST10704-91) 273 х 7,0 - 1 - PUF – PE
The designation of prefab short type PUF-insulated steel elbows in PE sheath consists of the following characters:
1. Elbow 90 means aelbow, 90 standing for the elbow angle;
2. «St 20» is the steel grade;
3. «GOST10704-91» is the State Standard for steel straight-seam arc-welded tube;
4. «273» is the workpiece tube dia. in mm
5. «7,0» is the wall thickness of the workpiece tube, in mm;
6. «1» is the insulation type;
7. «PUF – PE» stands for PUF insulation and PE protective sheath.
Note
On customer’s approval, it is possible to manufacture short type PUF-insulated steel elbows in PE sheath with changed wall thickness, increased PUF layer thickness, custom elbow angles and weld-end lengths.
