Notes:
1. The mass of the pipes calculated at steel density of 7.85 g/cm.
2. Pipes of other sizes are supplied according to special technical conditions.
The symbol teardrop-shaped normal pipe size 36 mm, 12 mm and with a wall thickness of 1.5 mm of steel grade 10:
Pipe 36121,5−10 GOST 8638−57
When referring to the teardrop-shaped pipe type And, after the word «pipe» should be inserted Litera A.
2. Pipe length and permissible deviations in shape and dimensions — according to GOST 8639−82.
3. Material and technical requirements for drop pipes to relevant standards for the pipe of circular cross-section.
