The bottom of API 650 aboveground welded storage tanks

API 650 is the standard for welded tanks for oil storage. It specifies the API 650 aboveground welded storage tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.

Vertical Storage Tanks Security against Damage
The assemblies of relieving devices shall be secured against damage in service, the effects of storms, or mishandling. Access ladders and platforms that meet API 650 aboveground welded storage tanks plant safety rules are suggested.
Vacuum-relieving Devices
A vacuum-relieving device, when used, shall be as direct in inflow as possible with no pockets where moisture can collect, and it shall have no piping except a weather hood ahead of the inlet. An adequate vacuum-air inlet shall also be provided.

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

BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, API 650 aboveground welded storage tanks , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API 650 aboveground welded storage tanks principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
