ASTM A27 grade 65-35 floating roofs API standard 650 aboveground welded storage tanks

API standard 650 is typically used for carbon, stainless steel and aluminium API standard 650 aboveground welded storage tanks tanks located in terminals, refineries, pipelines and other process facilities. Both have different pressure and temperature parameters as well. Your choice of model will depend on you and/or your client s particular needs.

Some defects may be found after the regular safety inspection for the API standard 650 aboveground welded storage tanks. The common API standard 650 aboveground welded storage tanks defects are: Tank cracks, tank welding defects. The cracks on the base metal, surface and near surface of the tank wall shall be eliminated by grinding with circular arc, and then magnetic particle inspection or re inspection shall be carried out. Cracks in heat affected zone: generally, grinding method is used to eliminate cracks, and magnetic particle or dye flaw detection is used to confirm that there is no crack, and then repair welding or grinding smooth transition.

Cylindrical Oil Storage Tanks Discharge Pipes
When a discharge pipe is used on the outlet side of such relieving devices, its area shall be not less than the area of the valve outlet, or if a single pipe provides for discharge from several relief devices, its area shall be not less than the aggregate area of the valve outlets. The API standard 650 aboveground welded storage tanks discharge pipe shall be fitted with an open drain to prevent water or other liquids from lodging in the discharge side of the valves.
Discharge pipes shall be supported so that no undue stress is placed on the valve body. Open discharges shall be placed and oriented so that the outflow is directed away from the tank and will not create a hazard over walkways, stairways, or operating platforms.

We have Business Department, Transportation Department, Document Department, Shipping Department, E-C department, Procurement Department, Finance Department, Human Resources Department, Administration Department, Logistics Department, After-sales so on Departments. Each department performs its own duties, unites and cooperates, and contributes its greatest strength to the overall operation of the company. So as to ensure the stable and sustainable development of the company.

The mode of iron and API standard 650 aboveground welded storage tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API standard 650 aboveground welded storage tanks steel logistics.
