LNG cylinder testing equipment requirements 1, require the test environment: plant to meet the full-year continuous test operation; plant ventilation, non-enclosed space. Quality assurance testing requirements; secure test security measures; cylinder storage, storage means required by the zoning, without disturbing each other, to identify whether clear; cylinder storage, preservation and inspection turnaround, which are not to damage the outer surface of the cylinder dedicated facilities or holder. 2, the residual gas bottle treatment: first determine the pressure and the nature of the residual gas bottle; then release the residual gas and have protective clothing, equipment and tools to safely handle; for recovering residual flammable gas or liquid, the replacement and disposal process documents means and sealed, comprising: a compressor with positive pressure method, residue tank and associated process piping and the like; hydrocarbon vacuum method using pump, residue tank, the injector (or aggregator) and related process pipelines; tools have been blocked cylinder valve handle; the documents have environmental protection and fire protection. 3, should be equipped with LPG cylinders or cylinder steam purge incineration equipment; documents have environmental and fire; the steam purge requirements steam pressure not less than 0.2MPa, time is not less than 4min; cylinders have burned equipment Temperature control devices and feed rate control means, and to ensure continuous production; with a combustible gas analyzer; there must be environmental protection and fire safety documents; 4, at least one or within the safety of endoscopic test surface (≤ 24V) lighting devices; 5, non-destructive testing equipment (magnetic particle or infiltration), if necessary-ray detection machine Taiwan (Note 1); 6, thickness 1 set (multiple cylinder test unit 2), accuracy should be ± 0.1%; 7, at least one weighing scales. Weighing range: 1.5 to 3.0 times; test period: three months. 8. Hydrostatic test method is in line GB / T9251 standard. 9, liquefied natural gas (LNG) cylinder test, pre-installation purge gas supply system operation, namely nitrogen replacement device Taiwan. 10, cold test operation. . 11, cylinder valve is automatically installed equipment at least one. 12. Tightness test requirements: meet the tightness test device regulatory requirements, special fittings; nitrogen purity used should not be less than two indicators GB3864 Ⅱ class prescribed. 13. Cylinders used scrap processing equipment should meet the requirements of cutting or squashed.
