API standard 650 special tank bottom plates welded to the shell

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API standard 650 special tank), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

Normal pressure API 650 storage tank: When the gas side pressure of API 650 storage tank is the same as atmospheric pressure or less than 13 atmospheres (gauge), API standard 650 special tank is called atmospheric storage tank. API 650 petroleum storage tanks low pressure storage tank: when the pressure is greater than 13 atmospheres (gauge) and less than 0.1MPa, it is called low pressure storage tank.

In 2015, we participated in an tender for oil and casing pipe in Pakistan. Because of our professional service and company strength. The end user chose us as the final contractor of the project of 22000 meters pipes of different sizes production. It takes us about 3 months to produce all the pipes API standard 650 special tank . We use bulk vessel to ship the pipe to Karachi port. Our engineers went to Karachi port to inspect the condition along with the customer when ship arrive. The customer gave high appraise to the pipe quality and our service

During the use of API standard 650 special tank, the tank material is prone to crack and leakage under the action of pressure, corrosion, wear and other conditions. Especially in the oil producing area, the temperature difference in four seasons is large and the natural environment is bad, which will accelerate the consumption of oil storage tank and cause many potential safety hazards. Therefore, the API standard 650 special tank must undergo strict inspections before being put into use after the production and installation are completed, so as to avoid cracks and leakage in short-term use and affect production safety.
