About Pressure Pipe Installation Unit Qualification Certification

Looking forward to it, I haven't done this, can't they provide something like this, you implement it one by one according to the above!

In the licensed program, GAL A can cover GAL B and GA2, and GAL B can cover GA2, GCL level can cover GC2 and GC3 levels, GC2 level can cover GC3 level, GDL level license can cover GD2 level, long-distance (oil and gas) pipeline pressure plugging and pipeline on-site anti-corrosion operation permit Class A can cover grade B; The special conditions of GCL air separation unit are GC2, and the special conditions of centralized gas supply and refrigeration in GC2 are GC3.

The license items applied for by the installation unit also contain "GA", "GCL", "GDL", "long-distance (oil and gas) pipeline pressure plugging", "pipeline on-site anti-corrosion operation (Class A)" and other categories of licensed items, by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China.

Pressure piping features:

1. The pressure pipeline is a system, which is interrelated and affects each other, and affects the whole body.

2. The ratio of length to diameter of the pressure pipeline is very large, which is easy to lose stability, and the force situation is more complex than that of the pressure vessel. The fluid flow state in the pressure pipeline is complex, the buffer margin is small, and the frequency of change of working conditions is higher than that of the pressure vessel (such as high temperature, high pressure, low temperature, low pressure, displacement deformation, wind, snow, etc. may affect the force of the pressure pipeline).

3. There are many kinds of pipeline components and pipe supports, and various materials have their own characteristics and specific technical requirements, and the selection of materials is complex.

4. There are more possible leakage points on the pipeline than the pressure vessel, and there are usually five places in only one valve.

5. There are many types and quantities of pressure pipelines, and there are many links in design, manufacturing, installation, inspection and application management, which are very different from pressure vessels.

One. Class GA [long-distance (oil and gas) pipelines]: Long-distance (oil and gas) pipelines refer to pipelines used to transport (oil and gas) commodity media between production areas, storage warehouses and user units, which are divided into GA1 and GA2 grades.

Two. GB (public pipelines): Public pipelines refer to gas pipelines and heat pipelines used for public utilities or civil use within the scope of cities or towns, which are divided into GB1 and GB2 grades.

Three. GC (industrial pipelines): Industrial pipelines refer to the process pipelines, public works pipelines and other auxiliary pipelines used to transport process media belonging to enterprises and institutions, which are divided into GC1, GC2 and GC3.

4. Thermal power plants are used to transport steam, steam and water two-phase medium pipelines, which are divided into GD1 and GD2 grades.

5. The pressure plugging permit for long-distance (oil and gas) pipelines is divided into Class A and Class B.

6. The on-site anti-corrosion operation of pressure pipelines is divided into Class A and Class B.

I have a project to bid, need GB equipment installation, transformation and maintenance license, do you have it?

Legal basis: Article 3 of the "Provisions on the Safety Management and Supervision of Pressure Pipelines" These provisions apply to pipelines and their ancillary facilities that meet one of the following conditions:

1) Pipelines transporting extremely hazardous media as specified in GB5044 "Classification of Occupational Exposure to Toxic Substances";

2) Pipelines transporting Class A and B media with fire hazards specified in GB50160 "Code for Fire Protection Design of Petrochemical Enterprises" and GBJ16 "Code for Fire Protection Design of Buildings";

3) The maximum working pressure is greater than or equal to the gauge pressure, the same below), and the pipeline where the conveying medium is gas (steam) and liquefied gas;

4) Pipelines with a maximum working pressure greater than or equal to a liquid in which the medium being flammable, explosive, toxic, corrosive or with a maximum working temperature higher than or equal to the boiling point;

5) Ancillary facilities and safety protection devices of pipelines specified in the preceding four paragraphs.

AQSIQ.

Conditions for Pressure Pipeline Installation Qualification License:

Qualification level requirements for pressure pipeline installation

The installation unit with GA1 installation qualification shall have the installation qualification of the corresponding variety of pressure pipelines of GA2 level, and the installation unit with GC1 installation qualification shall have the installation qualification of the corresponding varieties of pressure pipelines in GC2 and GC3. The installation unit with GC2 installation qualification, that is, the installation qualification of the corresponding variety of pressure pipes of GC3 level.

According to the provisions of the "Provisions on the Safety Management and Supervision of Pressure Pipelines", Article 1 is to standardize the qualification of pressure pipeline installation units (hereinafter referred to as installation units) and ensure the quality of pressure pipeline installation.

Article 2 within the scope of application of the "provisions" engaged in the installation of pressure pipelines, must have the corresponding category of pressure pipeline installation qualifications (hereinafter referred to as installation qualifications), and in accordance with the implementation rules (see Annex I for the format) to obtain the "pressure pipeline installation license". Extended data: pressure pipeline installation standard, A1GA class [long-distance (oil and gas) pipeline] refers to the pipeline used to transport (oil and gas) commercial media between the place of origin, storage and users, which is divided into gal and GA2.

The specific construction qualification needs to look at the scale of the gas station and the grade of the storage tank. Generally, spherical tank gas stations need to be qualified for the installation of pressure pipes above GC3 (spherical tanks can be installed).
