Materials of the main parts of the ball valve
Construction lengths of flange cranes according to GOST 28908
for pressure 1,b MPa – row 3
for pressure 2.5…4 MPa – row 2
for pressure 6.3…10 MPa – Table.2.
In the case of other construction lengths
, the first digit 0 is replaced by the digit 1 in the designation of the crane’s material design.
For example,
00 is replaced by 10,
01 by 11,
02 by 12, etc.
Construction lengths of coupling, fitting and welding cranes — in accordance with the design documentation (catalog).
