The highest design temperature of API 650 storage tanks

The API 650 specification provides guidelines for the API 650 storage tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.

Generally, external environment corrosion should be considered before design and construction of API 650 storage tanks and so on storage tanks. The corrosion on the outer surface of storage tank is often worse than that on the inner surface. Especially in the chemical industry area, there are often acid fog, alkali or salt dust in the atmosphere. These impurities form an active corrosive medium with dew or steam and oxygen in the atmosphere. The corrosion of the external environment of the storage tank shortens the maintenance period of the storage tank, even causes the storage tank to be scrapped in advance, which affects the normal operation of the storage and transportation.

Suggested Practice Regarding Installation of Low-pressure Storage Tanks
Access: All openings and accessories for tanks API 650 storage tanks constructed according to this standard shall be installed so that any periodic inspections required can be readily made.
Corrosion: When a tank bottom rests directly on the ground, a survey shall be made to establish the need for cathodic protection.
Drainage: All tanks in which water might accumulate under the hydrocarbon contents shall be provided with adequate drains that are suitably protected from freezing.

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

Management information and high efficiency. Because of the rapid flow of API 650 storage tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
