LNG tank for oil and gas industry internal components

API 620 Crude Oil Tank Non-pressure Parts
Welds for pads, lifting lugs, and other nonpressure parts, as well as temporary lugs for alignment and scaffolding attached to primary components, shall be made in full compliance with a welding procedure qualified in accordance with Q.6.1. Lugs attached for erection purposes shall be removed, and any significant projections of LNG tank for oil and gas industry weld metal shall be ground to a smooth contour. Plate that is gouged or torn in removing the lugs shall be repaired using a qualified procedure and then ground to a smooth contour. Where such repairs are made in primary components, the area shall be inspected by the liquid-penetrant method. A visual inspection is adequate for repairs in secondary components.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.

To scientifically evaluate the remaining service life of the LNG tank for oil and gas industry, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the LNG tank for oil and gas industry, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the LNG tank for oil and gas industry are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel LNG tank for oil and gas industry storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.
