foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents"
drafting:
This document replaces GB/T 28055-2011 "Technical Specifications for Hot Plugging of Steel Pipelines": Compared with GB/T 28055-2011, except
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) The scope of application adds "hydraulic active sealing, double-stage sealing sealing, intelligent sealing operations" (see Chapter 1);
b) The terms and definitions of "hydraulic active sealing", "two-stage sealing sealing" and "intelligent sealing" have been added (see 3:18, 3:19, 3:20);
c) Added the specific requirements for the manufacturer of plugging pipe fittings and welding under pressure (see 4:1, 4:4);
d) Added welding process form of hot-pressed pipelines (see 9:6:1);
e) Added the specified requirements for the opening reinforcement of the half-way tee (half-way four-way) (see Chapter 10);
f) Deleted "Figure 5 Schematic Diagram of surfacing welding form of circumferential fillet weld" (see Figure 5 of the:2011 edition);
g) Added installation requirements for double-stage sealing plugging heads and hydraulic active plugging heads (see 10:3:2:5, 10:3:2:6);
h) The detailed requirements for the pressure test after the bypass pipe is welded are added (see 10:3:5);
i) The requirements for gas protection during pipe breaking operations have been added (see 10:8);
j) Added the requirements for cold protection and heat preservation measures for equipment during construction in extremely cold weather (see 11:3:3:1):
