How to test roof seams of API 650 cylindrical welded storage tanks

In the final analysis, the market competition is the competition for customers. Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work. The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service.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 API 650 cylindrical welded storage tanks 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.API 650 can store oil, gas, chemical, water and biofuel for some of the most common tanks in the oil industry. API 650 can store contents at a lower pressure (maximum of 2 PSI) but at much higher temperature (-40 degrees F to 500 degrees F) than the standards of API 650 cylindrical welded storage tanks. It can be any tank size.Service concept:Customer satisfaction is our value. Thank customers for their trust, respect their rights and interests, care about their needs, understand their concerns, realize their satisfaction and promote their success. Sincere and friendly, warm and thoughtful, relaxed and pleasant, considerate and tolerant. Attentive service, sincere care, professional excellence. The first-class famous products API 650 cylindrical welded storage tanks at home and abroad gather, and the outstanding charm of the East and the West radiates! Specialization, standardization, refinement, kinship.High temperature heat transfer oil fin tube heating device for large API 650 cylindrical welded storage tanks has the advantage of high heat transfer efficiency. The high-temperature heat-conducting oil finned tube heating device adopts high-efficiency outer finned tubes. The outer finned tube coils are immersed in a water bath. Compared with ordinary light tubes, the contact area between the evaporation coils and the medium is increased. The total heat transfer coefficient of the coil is determined by the heat transfer coefficient outside the tube. This increases the heat flux per unit tube length and improves the overall heat transfer efficiency.
