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.
