Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 22513-2013 "Wellhead devices and Christmas trees for drilling and production equipment in the oil and gas industry".

Compared with GB/T 22513-2013, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

a) Added some definitions (see Chapter 3);

b) Added material code 95K (see Chapter 7);

c) Changed the content of quality control, and compiled the factory acceptance test into a separate chapter (see Chapter 11, Chapter 12, 2013 version of Chapter 7);

d) Added some flange and valve specifications (see 15.2);

e) Added requirements for valve stems (see 15.12.2.1);

f) Added requirements for hardening process of valve sealing mechanism (see 15.12.3.4);

g) The fracturing head multi-pass is added (see 15.20);

h) The content of repair and remanufacturing has been deleted (see Chapter 11, Appendix N of the 2013 edition).

This document was first published in 2008, revised for the first time in 2013, and this is the second revision.
