Fuel oil5 times the design repulsion force for overall water pressure test, the water temperature should not be lower than 15C, and the pressure should be maintained for 20min. There should be no leakage: Then, reduce the water pressure to the design standard force, stabilize the pressure by 20mm, and do a comprehensive inspection at the same time. There should be no leakage. After the water pressure test, the water should be blown down with air. The chloride ion content in the water of the stainless steel oil transfer arm should not be higher than 25trg/1.5.2.3 When the conveying medium is liquefied petroleum gas, an air tightness test should be carried out, and the test medium temperature should not be lower than 5℃. Carry out a slow rotation test under the design pressure, stabilize the pressure by 30mm, and there should be no leakage. 5

The above tests and inspections are carried out one by one. When one or more of them are unqualified, it is called After the parts are properly adjusted, they are tested again until they are qualified.
7 Painting, marking, packaging, transportation
Before painting, the steel coating should be treated according to the requirements of GB/192, grade 21/27.1
SY/T5298—2002
7.2 The painting of the oil loading arm should meet the relevant requirements of CB/T3798, and the adhesion of the paint film should meet the first-level quality requirements of GH/9286. If there are special requirements, it can also be processed according to the user's requirements. The specified paint type and painting process are used for painting. The topcoat color is agreed upon by the manufacturer and the user. 7.3 The mating surfaces, sealing surfaces and other non-painted parts of the parts should be protected with industrial grease. 7.4 The packaging of the oil transfer arm should be carried out strictly in accordance with the requirements of the drawings. The spare parts are packed in bags and then packed in boxes: 7.5 The packaging box is lined with a layer of moisture-proof felt paper. There should be reliable fixings and supporting parts in the box to ensure that the spare parts are fixed in the box. 7.6 The inlet and outlet of all parts and the connecting flanges are all closed to prevent dirt from entering. Pipe mouth: 7.7 The exposed parts transported by flatbed trucks should be placed on necessary brackets, and all movable parts should be tied and fixed to ensure that parts, components and paint films are not damaged under all transportation conditions. 7.8 A metal nameplate should be fixed at the designated position in front of the oil transfer arm column. The nameplate should indicate the following: a) Product name and model; b) Main technical parameters (design pressure, nominal diameter, deadweight, etc.); c) Product number, (factory date; d) Manufacturer's name and address. 7.9 Random technical documents include: a) Product quality certificate; b) Product installation and operation instructions; c) Main engine assembly drawing; d) Packing list.
