Pressure Pipe Safety Technology Supervision Regulation for
Industrial Pressure Pipe
1 General Provisions
Article 1 This regulation is 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
development.
Article 2 This regulation is applicable to process plants, auxiliary equipment and industrial
pressure pipes (hereinafter referred to as "pipes") affiliated to the public works within the
battery limit. All the process plants, auxiliary equipment and pipes shall meet all of the
following requirements:
(1) Highest operating pressure is greater than or equal to 0.lMPa (gauge pressure, the
same below);
(2) Nominal diameter (NOTE 1) is greater than 25mm;
(3) Conveyance medium is gas, steam, liquefied gas, liquid whose highest operating
temperature is higher than or equal to its normal boiling point or combustible,
explosive, 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 DN.
NOTE 2: Pipe components are used to connect or assemble the pressure-bearing and enclosed pipe systems, including pipes, pipe
fittings, flanges, sealing members, fasteners, valves, safety protection systems, compensators, flexible joints, pressure hoses,
filters (such as Y-shape and T-shape), throttling devices (such as orifice plates) in the pipes and segregators.
NOTE 3: Pipe support parts, including steeves, spring supporters and hangers, diagonal bars, balance weights, elastic bolts,
support bars, chains, guideways, cradles, bases, rollers, brackets, sliding supports, lifting eyes, hangers, clasps, pipe clips,
U-clamps and plywoods.
Article 4 The following pipes shall comply with provisions specified in other relevant safety
technology regulations:
(1) Pipes whose nominal pressure is above 42MPa;
(2) Non-metallic pipes.
Article 5 This regulation is not applicable to the following pipes:
(1) Pipes special for the electrical equipment and telecommunication;
(2) Power pipes;
(3) Pipes for military equipment and nuclear facilities;
(4) Pipes for offshore installations and pipes down the mine;
(5) Pipes special for mobile equipment like railway locomotives, automotives, ships and
aerospace crafts;
(6) Pipes for petroleum, natural gas and terrestrial heat exploration and excavation
devices;
(7) Long-distance (oil-gas) pipes and oil/gas field gathering pipes;
(8) Pipes for town and municipal utilities;
(9) Pipes belonging to the body of refrigeration and air conditioning equipment as well as
pipes special for heating and ventilation;
(10) Other pipes within the scope specified in "Regulations on Safety Technology for
Special Equipment".
Article 6 Manufacturing of the pipe elements and the design, installation (including the field
fabrication, the same below), reconstruction, maintenance, application and inspection/testing
shall be in accordance with this regulation.
The quality and technical supervision departments (hereinafter referred to as "quality
inspection departments") at all levels are responsible for the safety supervision of pipes and
for the supervision of the implementation of this regulation.
Article 7 This regulation specifies basic safety requirements for the pipes, other provisions
(such as technical standards and internal enterprise provisions) shall not be lower than the
requirements of this regulation.
Safety management personnel and operators of pipes shall obtain corresponding "Special
Equipment Operator Certificate".
2 Pipe Elements
2.1 Basic Requirements
Article 14 The design pressure of standard parts of the pipe elements shall be in accordance
with the requirements specified in the relevant safety technology regulations and their
corresponding standards. Non-standard pipe elements shall also be provided with design
calculations and drawings.
Article 15 Manufacturing organizations of pipe elements shall obtain "Manufacture License
for Special Equipment" and shall accept the supervision and inspection for their product
manufacturing process by the special equipment inspection and testing institutions in light of
the relevant safety technology regulations.
Article 16 Manufacturing of the pipe elements shall be provided with design (technical)
documents and manufacturing process documents and also shall meet the requirements in the
relevant safety technology regulations and their corresponding standards.
Article 17 Manufacturing of the pipe components shall be in accordance with provisions
specified in the relevant safety technology regulations and their corresponding standards. As
for the welding (including the repair welding) in the manufacturing process, welding
procedure qualified through assessment shall be adopted and welders with qualification
certificate shall be responsible for the welding. Welding procedure qualification and welder
performance qualification tests shall be in accordance with the requirements specified in the
relevant safety technology regulations and their corresponding standards.
Article 18 Manufacturing organizations of pipe elements shall provide product quality
certificate documents stamped with their quality inspection seals according to the supply
batches of the pipe element...
