Quality inspection of API Std 650 ambient temperature tanks

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API Std 650 ambient temperature tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.

The water dissolved in the oil will be separated out from the oil stored in the API Std 650 ambient temperature tanks for a long time, and the acidic water layer will appear at the bottom of the API Std 650 ambient temperature tanks for a long time, which will accelerate the corrosion of the API Std 650 ambient temperature tanks and cause the wall thinning and even leakage. With the increase of service life, the API Std 650 ambient temperature tanks must be inspected and cleaned regularly to check the hidden danger.

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 Std 650 ambient temperature 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.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API Std 650 ambient temperature tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver API Std 650 ambient temperature tanks goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.
