API 650 welded steel oil storage tanks vacuum breakers

For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API 650 welded steel oil storage tanks Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.

How to effectively increase the service life of API 650 welded steel oil storage tanks oil tanks? It is necessary to check and inspect the oil tank regularly in the process of use, and do a good job in the maintenance and cleaning of the oil tank. The oil tank should be inspected every 6 years. With the increase of service life, the inspection interval should be shortened. Daily maintenance and cleaning of the API 650 welded steel oil storage tanks can prolong the service life of the oil tank. The maintenance of the API 650 welded steel oil storage tanks mainly includes the anti-corrosion inspection of the oil tank, the maintenance of the accessories, and the cleaning of the sediment in the tank.

Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API 650 welded steel oil storage tanks and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API 650 welded steel oil storage tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API 650 welded steel oil storage tanks steel transportation industry.
