Compared with.2013, except for structural adjustment and editorial changes, the main technical changes are as follows.
--- Changed the range of pressure components, increased the start (soda) separator (see Chapter 1, Chapter 1 of the.2013 edition);
--- Changed and added the terms and definitions used in this section (see Chapter 3, Chapter 3 of the.2013 edition);
--- Changed the scope of use for the calculation of low cycle fatigue life, allowing the start (soda-water) separator to be used as a reference (see 4.2,.2013 edition of
---Increase the allowable stress value of materials between adjacent temperatures to be determined by arithmetic interpolation and the allowable stress value of materials should be rounded off after the decimal point
the numerical provisions (see 5.2.1);
--- Changed the relevant provisions for determining the calculation pressure (see 7.3, 7.3 of the.2013 edition);
--- Increase the calculation provisions for the reinforcement of convex head openings (see 10.3.8, 11.2, 11.3.6, 11.5.6, 11.5.8);
--- Added the calculation method for convex heads under external pressure (see 10.3.9);
--- Increased the scope of application of the formula for calculating the thickness of elbows or elbows and arc-shaped header cylinders (see 10.6.5);
--- Increased the weld height specification for the opening reinforced nozzle (see 11.4.2, 11.5.8);
--- Changed the size requirements (L1, hmin, r), specification range, and structural requirements of the tee (see 15.3.12~15.3.28,.2013 edition
--- Delete the provisions of the minimum radial residual thickness of the incision part of the sealing surface of the convex head manhole (see 16.3.11 of the.2013 edition);
--- Changed the content of "Calculation of low cycle fatigue life of boiler drum" (see Appendix A, Appendix A of the.2013 edition);
--- Changed the relevant content of the verification method for determining the maximum allowable working pressure of components (see Appendix B, Cha
