Pressure Pipe Safety Technology Supervision
Regulation for Industrial Pressure Pipe
Issued by General Administration of Quality Supervision, Inspection
and Quarantine of the People's Republic of China
May 8,2009
In November 2002, Bureau of Safety Supervision of Special Equipment of the General
Administration of Quality Supervision, Inspection and Quarantine {GAQSIQ) (hereinafter
referred to as "Bureau of Special Equipment") assigned the Sub-Technical Committee for
Safety of Pressure Pipes with the National Technical Committee for Standardization of Boiler
and Pressure Vessels (hereinafter referred to as "Pipe Subcommittee") to make a draft of this
regulation. In December 2002, Pipe Subcommittee organized the relevant experts to establish
drafting group and held working conference in Shanghai, and then formed preparation
outlines and basic contents of "Pressure Pipe Safety Technology Supervision Regulation for
Industrial Pressure Pipe". In August 2003, the second plenary meeting was held in Shanghai,
in which the major issues in terms of the drafting work were discussed. In June 2004, the third
plenary meeting was held in Shanghai, in which the draft of "Pressure Pipe Safety
Technology Supervision Regulation for Industrial Pressure Pipe" was formed through
discussion and modification. At the same time, the relevant experts were invited to discuss on
the draft, which was modified referring to the experts' suggestions. In November 2007, the
drafting group held working conference in Beijing. In comparison with the being-modified
standard and giving consideration to the current management style of the national industrial
pressure pipes, this draft was further modified and draft standard for comment was formed. In
January 2008, according to the requirements of Document Zhi Jian Te Han [2008] No.4, the
Bureau of Special Equipment sought opinions from the grassroots department, the
departments concerned and experts and citizens, then the drafting group made some
modification and formed draft standard for examination according to the solicited opinions. In
April 2008, the Bureau of Special Equipment submitted the draft standard for examination to
special equipment safety technology committee of GAQSIQ for consideration and the
drafting group, in light of the deliberation opinions, made some modifications and formed the
draft standard for approval, which was approved and issued by GAQSIQ on May 8, 2009.
Giving consideration to the actual state of the safety technology for pressure pipes and
those requirements in the relevant national administrative licensing, this regulation specifies
the basic requirements for safety performance of pressure pipes in the aspects of materials,
design, manufacture, installation, application, maintenance, reconstruction, periodic inspection
and safety protection devices in order to achieve the goal of regulating the supervision and
control of pressure pipes.
Participating organizations and staffs of this regulation are.

Pressure Pipe Safety Technology Supervision Regulation for
Industrial Pressure Pipe
1 General Provisions
Article 1 This regulation was formulated in line with the "Regulations on Safety Supervision
for Special Equipment", with a view to ensuring the safety operation of industrial pressure
pipe, ensuring the personal and property safety of the people and promoting the economic
Article 2 This regulation is applicable to process plants, auxiliary equipments and industrial
pressure pipes (hereinafter referred to as "pipes") affiliated to the public works within the
battery limit. All the process plants, auxiliary equipments and pipes shall meet all of the
following requirements.
(1) Maximum operating pressure is larger than or equal to O.lMPa (gauge pressure,
similarly hereinafter);
(2) Nominal diameter (Note 1) is larger than 25mm;
(3) Conveyance medium is gas, steam, liquefied gas, liquid whose maximum operating
temperature is higher than or equal to its normal boiling point or combustible, flammable,
noxious and corrosive liquid.
Article 3 This regulation is applicable to the following pipe scope.
(1) Pipe elements, including pipe components (Note 2) and pipe support parts (Note 3);
(2) Joints between pipe elements, the first joint (weld, flange, sealing member and
fastener, etc.) connecting the pipe and equipment or device, and joints between the pipes and
non-pressure parts;
(3) Safety valves, bursting disc devices, flame arresters, emergency shutoff devices and
other safety protection systems used for the pipes.
Note 1. The nominal diameter is the inside nominal diameter and nominal dimension, the code is usually indicated in
