This standard is revised based on the requirements of the former China National Petroleum and Natural Gas Corporation's (China National Petroleum and Natural Gas Corporation) Zhongyoujianzi No. 42 document to (Technical Standard for Magnetic Exploration with Pressure Welding) SYJ4044-89.
This standard mainly includes: general principles, terminology, qualification of inspectors, testing equipment, aldehyde powder and magnetic fluid, sensitivity test piece, on-site selection, pre-test and record, re-test, evaluation and test report, etc. This standard has been modified, exempted and improved 5Y4(4-89, mainly adding the content of aldehyde detection and evaluation of water and steel pipelines. This standard will be effective from the date of the establishment of China National Natural Gas First Construction Company, and will be updated from 5Y4044-39. The main editor of this standard is China National Natural Gas First Construction Company, and the participating editors of this standard are Zhu Xishan, the main person in charge of this standard.

Technical standard for powder particle testing of pressure-sensitive steel storage tanks and pipelines
1 General testWww.bzxZ.net
1.0.1 To unify the technical requirements for steel cutting and welding storage pipelines (hereinafter referred to as storage pipelines) [hereinafter referred to as storage pipelines] to ensure the quality of storage and pipeline testing, technical standards are formulated.
1.0.2 This standard applies to the raw materials and welded plastic surfaces of storage pipes, and the detection and assessment of the number of powders that are close to the surface. The detection of bacterial powders of storage pipes includes the main body and the accessories connected to the main body. The magnetic particle detection of the pipeline is applicable to pipelines that transport crude oil, finished products, natural gas, fossil fuels and other materials (including injection water and industrial gas pipelines), and the outer diameter should be greater than 70
13 This standard stipulates that the following methods should be adopted:
1.0,4 The detection of powders in the pipeline shall comply with the relevant national standards for the detection of mixed products. 2.0.1 Inline indication: Linear indication refers to the indication of magnetic traces with a length greater than 3 times the width. 2.0.2 Circular indication: The indication of magnetic traces with a length less than or equal to 3 times the width. 2.0.3 Chain indication: Chain Chain-shaped circular refers to 4 particles with a diameter greater than 1.5m and a distance less than 1.5mm on the same straight line. 3 Qualifications of testing personnel
3.0.1 Powder detection personnel must undergo technical training, master the methods and techniques of micro-detection, including performing inspection operations, identifying and evaluating results, and pass the examination of relevant technical qualification assessment institutions. They can only operate after obtaining the micro-detection qualification certificate.
3,U.2 The inductive powder detection personnel from whom the powder detection personnel come should be consistent with the level of the magnetic particle detection qualification certificate they hold: those who issue inspection reports must hold a powder detection qualification certificate of level 1 or above.
3.3 Magnetic particle inspection personnel must have their vision checked once a year. Those with corrected vision below 1.0 for near or far distance are not required to participate in magnetic particle inspection assessment. 4 Inspection equipment
4.0.1 The technical indicators of magnetic particle inspection equipment must comply with the provisions of (magnetic particle detection machine) C3721.
4.0.2 The distance between the electrodes of the electric energy should be continuously adjustable within the range of 50~20mm. When the distance between the electromagnetic plates is 2mm, the AC magnetic field should have a minimum of 4N. The AC rotating field transmission force should comply with the requirements of the equipment manual.
4.0.3 When the infrared method is used for moisture inspection, the external lamp used shall be as shown in the table above. The UV intensity of the surface should not be less than Um, and the range of UV rays is 32-0.40um.
4.1.4 When conducting powder testing, the following auxiliary materials should be available: magnetic break indicator (octagonal test piece), human-shaped test piece and (type test piece; 1
magnetic suspension liquid concentration measuring tube;
35-10 station stock pot:
4 light explosion intensity;
5 ultraviolet lamp;
ultraviolet lamp intensity meter.
4.0.5 The magnetic object detection equipment should be calibrated once a year, and it can be corrected after six years of maintenance. If the equipment is used for "years or more, it should be able to pass the calibration after use.5. The magnetic detection equipment should be calibrated once a year and will not be out of service after six times of maintenance. If the equipment is used for "a year or more, it should be calibrated again before use.5. The magnetic detection equipment should be calibrated once a year and will not be out of service after six times of maintenance. If the equipment is used for "a year or more, it should be calibrated again before use.
