Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 18816-2002 "General technical conditions for marine heat exchangers." This standard and GB/T 18816-2002 phase
Ratio, the main technical changes are as follows.
--- Scope added "evaporator" (see Chapter 1, Chapter 1 of the 2002 edition);
--- Modify the strength calculation method (see 32, 2002, version 3.2.);
--- Modify the material requirements (see 33, 2002 version 3.3.);
--- Increased head shape factor (see Table 3);
--- Increasing the minimum thickness of the U-tube heat exchanger tube plate calculation method (see 3.2.5);
--- Ω modified heat exchanger expansion joint opening width requirements (see 349, 2002 edition of 3.4.10.);
--- Modify the setup requirements for temperature measuring device (see 3415, 3416, 2002 edition of 3.4.15,3.4.16...);
--- Butt welds modified cylinder counterpart wrong side requirements (see 353, 2002 edition of 3.5.3.);
--- Modify the tube plate and pipe Expansion after the tube plate deformation punch volume requirement (3.8 4, 2002 edition of 3.8.4).
