Select "pressure" mode to calculate allowable pressure for specified wall thickness, or "wall thickness" mode to determine minimum thickness for given pressure.
Wall thickness calculations adhere to minimum requirements per:
SNIP 2.05.06-85 section 8.22
RD 10-249-98 section 3.3.1.3, table 3.3
GOST 32569-2013
GOST 32388-2013 table 1.3
For SNIP 2.05.06-85, additional wall thickness verification uses formula (66) section 13.16.
Wall thickness values round up to 0.1 mm.
