API Std 650 mechanically-anchored flat-bottom tanks welding requirements

API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API Std 650 mechanically-anchored flat-bottom tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API Std 650 mechanically-anchored flat-bottom tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.

High temperature heat transfer oil fin tube heating device for large API Std 650 mechanically-anchored flat-bottom 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.

Density of API Std 650 mechanically-anchored flat-bottom tanks Liquid Stored
The density of the liquid stored shall be its maximum density within the range of design temperatures, but no less than 29.3 lbf/ft3 for methane, 34.21 lbf/ft3 for ethane, and 35.5 lbf/ft3 for ethylene.
Design Metal Temperature
The design metal temperature of each component exposed to the liquid or vapor being stored shall be the lower of the temperatures specified as follows: The design metal temperature of the components of the API 620 single-wall tank or the inner tank of a double-wall tank shall be the minimum temperature to which the tank contents shall be refrigerated, including the effect of subcolony at reduced pressure.

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the API Std 650 mechanically-anchored flat-bottom tanks steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its API Std 650 mechanically-anchored flat-bottom tanks steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
