API 650 floating-roof tanks datum plate

Operation points of sand blasting rust removal for metal storage tank, API 650 floating-roof tanks:
1. The equipment should be as close as possible to the workpiece to be processed, so as to reduce the pipeline length and pressure loss, avoid excessive pipeline wear, and facilitate the construction personnel to contact each other.
2. The jet pipe should be straight as much as possible to reduce the concentrated wear at the bend. The wear direction of the bend should be changed frequently to prolong the service life of the pipe.
3. Strictly control the process parameters.

API standard 650 is typically used for carbon, stainless steel and aluminium API 650 floating-roof 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.

The mode of iron and API 650 floating-roof 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 650 floating-roof tanks steel logistics.

Impact Tests for High Alloys
Impact tests are not required for the high-alloy (austenitic stainless steel) API 650 floating-roof tanks base materials, nickel alloy based materials, aluminum base materials, and weld deposited for the nonferrous (aluminum) materials. Impact tests are not required for austenitic stainless steel welds deposited by all the welding processes for services of –200°F and above. Austenitic stainless steel welds deposited for service below –200°F by all welding processes shall be impact tested in accordance with Q.6.2 except that the required impact values shall be 75% of the values as given in Q.2.2.2, Item c.
