Notes:

1. The new standard on pipes for boilers - TU 14-3P-55-2001
2. Brands became - 20, 20-PV, 12H1MF, 12H1MF-PV, 15HM, 15MA, 12H18N12TT
3. Length of pipes is up to 9 m (in coordination)
4. Pipes pass 100% nondestructive control
5. Pipes are intended for boilers and pipelines with high and ultrahigh characteristics of steam.
