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 28054-2011 "Steel Seamless Gas Cylinder Clustering Device": Compared with GB/T 28054-2011, except for structural adjustment in addition to general and editorial changes, the main technical changes are as follows:

a) The nominal working pressure range and the nominal volume range of a single gas cylinder have been changed (see Chapter 1, Chapter 1 of the:2011 edition);

b) Changed the cluster device structure diagram (see 4.1,:2011 version of 4:1);

c) The requirements for pipeline material grades and standards have been changed (see 5.1:2:1, 5:1:1:1 of the:2011 edition);

d) Changed the requirements for safety accessories and instruments (see 5.2:4, 5:3:6 of the:2011 edition);

e) Added requirements for implementation standards for gas cylinders in cluster devices (see 5.3:1:2);

f) The form of mobile frame is deleted (see 5.3:4:1 of the:2011 version);

g) Added requirements for vertical drop test (see 6.3:2);

h) Added requirements for rotational drop test (see 6.3:3);

i) Added type test requirements (see 7.3);

j) Added requirements for design changes (see 7.4);

k) Deleted the contents of nameplate type, nameplate font, and nameplate material (see 8.1:3 and 8:1:5 of the:2011 edition);

l) Delete the storage and transportation requirements (see Chapter 9 of the:2011 edition);

m) Delete the regulations on the safe use of filled combustible gas cluster devices (see Chapter 10 of the:2011 edition):
