Pressure pipe supervision inspection regulation
1 General
1.1 Purpose
In order to standardize the supervision inspection of pressure piping
components manufacturing (supervision and inspection is hereinafter referred
to as supervision inspection) and the supervision inspection of pressure
pipeline installation, modification and major repairs (installation, modification
and major repairs are hereinafter collectively referred to as construction), in
accordance with the "Special Equipment Safety Law of the People's Republic
of China" "Special Equipment Safety Supervision Regulations", this regulation
is hereby formulated.
1.2 Scope of application
1.2.1 Manufacturing supervision inspection
This regulation is applicable to the supervision inspection of the manufacturing
process of the following pressure piping components within the scope as
specified in the "Special Equipment Catalog":
(1) Submerged arc welded steel pipe, polyethylene pipe (Note 1-1);
(2) Gas pressure regulating device, temperature and pressure reducing
device, factory prefabricated pipe segment (Note 1-2), flow meter (shell)
(Note 1-3) in the component assembly device.
Note 1-1: It excludes polyethylene pipes with metal skeletons and fiber-
reinforced polyethylene pipes.
Note 1-2: Factory prefabricated pipe segment refers to the piping component
products manufactured by the manufacturer after welding and assembling
pressure piping components in the factory according to the construction design
drawings. It does not include the piping prefabrication performed by the
installation organization at the construction site.
Note 1-3: The temperature and pressure reducing devices, factory
prefabricated pipe segments, flow meters (shells) used in the pipelines within
the boiler range can be manufactured, supervisory inspected in accordance
with the relevant regulations of the boiler.
construction organization, non-destructive testing organization, etc.
The inspected organization shall do the following work:
(1) Pressure piping component manufacturers, design organizations,
construction organizations, non-destructive testing organizations shall
establish a quality assurance system and maintain its effective
implementation;
(2) Provide necessary working conditions; determine the responsible person
for supervision inspection work; do a good job in cooperation of
supervision inspection;
(3) The pressure piping component manufacturer shall submit a supervision
inspection application to the supervision inspection agency before the
product is manufactured; submit a production plan; provide real and
effective inspection materials in a timely manner (Note 1-5);
(4) The construction organization is responsible for coordinating the
implementation of supervision inspection matters, submitting a
supervision inspection application to the supervision inspection agency or
requesting the construction organization to submit a supervision
inspection application, timely coordinating and solving construction and
supervision inspection related issues;
(5) The construction organization assists the construction organization or
submits a supervision inspection application to the supervision inspection
agency according to its requirements; submits the construction schedule
plan;
(6) The construction organization and the non-destructive testing organization
shall inform the supervision inspection agency of the construction and
testing progress in time; provide true and effective inspection materials
(Note 1-5).
Note 1-5: The inspection documents refer to the technical documents,
inspection records, inspection and testing records, test and testing reports,
qualification lists of welding operators and non-destructive testing personnel
related to the inspected products and construction projects.
1.5 Supervision inspection agencies and supervisory inspectors
(1) The supervision inspection agency undertaking the supervision inspection
of manufacturing (construction) shall obtain the corresponding
qualifications approved by the department responsible for the safety
supervision and management of special equipment (hereinafter referred
to as the special equipment safety supervision department); the inspectors
The supervision inspection procedures generally include acceptance of
applications, preparations for supervision inspections, implementation of
supervision inspections, issuance of supervision inspection certificates.
2.1.1 Acceptance of applications
The pressure piping component manufacturer and building organization (or
construction organization) shall submit the application for the pressure piping
supervision inspection to the supervision inspection agency before
manufacturing or construction.
After the supervision inspection agency accepts the supervision inspection
application, it shall provide the applicant organization with a sample supervision
inspection contract; inform the applicant organization of the list of relevant
materials that need to be provided.
2.1.2 Preparation for supervision inspection
The supervision inspection agency compiles the supervision inspection outline
(plan) according to this Regulation and quality plan (construction program),
combined with the actual situation of manufacturing (construction); forms a
supervision inspection project team; appoints the person responsible for the
supervision inspection project team; allocates necessary supervision
inspections personnel; configures testing equipment, etc.
2.1.3 Implementation of supervision inspection
The supervision inspection agency shall, in accordance with Article 2.2 of this
Regulation as well as the requirements of the "Special requirements for
supervision inspection of pressure piping components manufacturing" (see
Appendix A), "Special requirements for supervision inspection of long-distance
piping construction" (see Appendix B), "Special requirements for supervision
inspection of public pipeline construction" (see Appendix C), "Special
requirements for supervision inspection of industrial pipeline construction" (see
Appendix D), combined with the technical characteristics and actual conditions
of the pressure pipeline, notify the items, contents and requirements of the
supervision inspection to the inspected organization in writing form. For long-
distance pipelines, the supervision inspection agency shall make disclosure of
the supervision inspection plan to the inspected organization in the form of a
meeting.
During supervision inspection, supervisory inspector shall carry out supervision
inspection work in accordance with the supervision inspection outline (plan).
Supervisory inspector can conduct supervision inspections on supervision
inspection items in accordance with safety technical specifications, relevant
standards, design documents through data review, physical inspection, on-site
(2) For physical inspection, supervisory inspector shall re-examine the self-
inspection qualified items of the inspected organization in accordance with
the items and requirements specified in this Regulation; verify whether the
results are true and correct, and whether they meet the requirements of
safety technical specifications and relevant standards;
(3) For on-site supervision, the supervisory inspector shall supervise the
manufacturing (construction) activities on-site in accordance with the
items and requirements specified in this Regulation; supervise whether
the manufacturing (construction) activities meet the requirements of safety
technical specifications, relevant standards, quality assurance system
documents.
If there are clear requirements on the number of sampling-checks in this
Regulation, follow this Regulation; if there is no clear requirement, the number
and methods of sampling-checks shall be specified in the supervision
inspection outline (plan) according to the implementation status of the quality
assurance system of the ins......
