Chapter I General Provisions
Article 1 In order to regulate (long-distance) pressure pipe service registration administration, this Regulation is formulated in accordance with "Regulations on Safety Supervision over Special Equipment", "Decision of the State Council on Establishing Administrative Licenses for Administrative Examination and Approval Items Really Necessary to be Retained", and "Provisions of Pressure Pipe Safety Administration and Supervision".
Article 2 This Regulation is applicable to the periodic inspection of long-distance land oil and gas pipelines (hereinafter referred to as pipelines) with conveyance medium of crude oil, refined oil, petroleum gas and natural gas, specified in "Regulations on Safety Supervision over Special Equipment" and "Provisions of Pressure Pipe Safety Administration and Supervision".
Article 3 Periodic inspection for pipeline generally include annual inspection, overall inspection and fitness-for-service assessment.
(1) Annual inspection refers to the routine inspection in the working process. Annual inspection shall be carried out at least once a year, and it may not be carried out in the year with overall inspection. Annual inspection is generally be carried out by long-distance pipeline working personnel from the using unit, or may be entrusted by qualified inspection and detection organization (hereinafter referred to as the inspection organization) approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (hereinafter referred to as AQSIQ).
(2) Overall inspection refers to risk-based inspection on pipelines by a certain test period. new pipelines are generally applied with the first overall inspection within 3 years after being put into operation, and the overall inspection period after the overall inspection shall comply with the requirements of Article 23; the inspection organization undertaking overall inspection shall be approved by AQSIQ and work within the approved working range；
(3) Fitness-for-service assessment is carried out after overall inspection and includes stress analysis calculation for pipelines; residual intensity evaluation for defects; safety evaluation for overproof defects which are harmful to the structural integrity of pipelines; pipeline residual life prediction for main potential hazard factors which are harmful to pipelines, and material applicability evaluation which is carried out under certain conditions. The organization undertaking fitness-for-service assessment (hereinafter referred to as the assessment organization) shall have fitness-for-service assessment qualification approved by AQSIQ.
Overall inspection and fitness-for-service assessment in periodic inspection shall adopt inspection and evaluation technology used in completeness management concepts, to carry out risk-based inspection testing and to determine serious fallout area of pipelines. The determination principles of serious fallout area shall comply with Appendix A.
Article 4 For pipelines with any of the following cases, the overall inspection period of pipeline shall be shortened properly:
(1) Located in serious fallout area;
(2) Ones suffering multiple leak accidents, natural disaster or serious third party destroy within 1 year;
(3) Those with stress corrosion, serious local corrosion or general corrosion;
(4) Ones bearing repeated load and resulting in possible fatigue failure;
(5) Ones with serious damage in anticorrosive (thermal insulation) layer or non-effective cathodic protection;
(6) Ones whose risk values are found relatively high in risk estimation;
(7) Ones found in annual inspection with severe problems except the previous ones in this article;
(8) Ones considered by inspectors and the using unit shall be shortened the overall inspection period.
Article 5 If exceeding risk acceptability, pipelines under one of the following cases shall be immediately applied with overall inspection and fitness-for-service assessment:
(1) Ones whose operating conditions change greatly and cause increase of operation risk;
(2) The variety of transmission medium is significant changed, and turned into more danger medium;
(3) Ones reused after being stopped using for more than a year;
(4) Those which annual inspection conclusion shows needed overall inspection;
(5) Ones with severe geologic hazards, such as earthquake, landslide and mud rock flow;
(6) Those with significant transformation and maintenance.
Article 6 Inspection organizations responsible for overall inspection, and evaluation organization and personnel of fitness-for-service assessment shall carry out overall inspection and fitness-for-service assessment of pipelines within the approved range, be supervised safety supervision authority by AQSIQ or local provincial quality technical supervision department, and be responsible for the work quality.
Article 7 The using unit shall prepare overall inspection and fitness-for-service assessment plan according to the requirements of overall inspection period; arrange works of overall inspection and fitness-for-service assessment; timely submit the plan of overall inspection and fitness-for-service assessment to the pressure pipe service registration department; and respectively propose overall inspection and fitness-for-service assessment requirements to the inspection organization and the evaluation organization a month before the fitness-for-service assessment validity period.
Before periodic inspection, the inspection organization and the evaluation organization must formulate overall inspection and fitness-for-service assessment schemes (including safety measures and emergency plan), and solicit using agency's opinion. the overall inspection and fitness-for-service assessment scheme is approved by the technical director authorized by the inspection organization and the evaluation organization.
Personnel engaged in overall inspection and fitness-for-service assessment must carry out overall inspection and fitness-for-service assessment in strict accordance with the overall inspection and fitness-for-service assessment scheme approved. When adjustments are required according to actual situations, they must be examined and approved by the technical director authorized by the inspection organization and the evaluation organization.
Article 8 The pipeline using unit shall do all the preparation works before the pipeline periodic inspection according to the requirements of this Regulation, to make the pipeline in a appropriate to-be-inspected state, and shall provide safe periodic inspection environment, be responsible for all the auxiliary works required in the periodic inspection, and assist the inspection organization and evaluation organization to carry out periodic inspection.
Inspectors shall seriously implement the safety management requirements of the pipeline using unit.
