API Standards

Standards2

API 650 : Welded Steel Tank for oil storage This Standard establishes minimum requirements for material, design, fabrication, erection, and testing for vertical, cylindrical,aboveground, closed- and open-top, welded carbon or stainless steel storage tanks in various sizes and capacitiesREFERING TO ASME Section V, IX

API 653 : Tank Inspection, Repair, Alteration and ReconstructionThis standard covers Above ground steel storage tanks built to API Standard 650 and its predecessor API 12C. It provides minimum requirements for maintaining the integrity of such tanks after they have been placed in-service and addresses inspection,repair, alteration, relocation, and reconstruction.

API RP 651 : Cathodic Protection of Above Ground Storage Tank (AST)

API RP 652 : Lining of Above Ground Storage Tank (AST)

API RP 575 :Inspection of Atmospheric and Low-Pressure Storage TanksThis standard provides useful information and recommended practices for the maintenance and inspections for AST.

API RP 571 : Damage Mechanisms Affecting Fixed Equipment in theRefining Industry

3 Types of Storage Tanks,Storage tanks in Turkey

1.1 Types of Atmospheric Storage Tank Roofs

The most common type of atmospheric storage tank is the fixed cone roof tank,

up to 300 ft (91.5 m) in diameter & 64 ft (19.5 m) in height (larger diameter tanks have been built, mostly outside the U.S.)

These roofs are normally supported by internal structural but can be fully self-supporting in smaller diameters (typically, 60 ft [3 m] diameter or less).

Types of Storage TanksATMOSPHERIC

1.1.1 Types of Atmospheric Storage Tank Roofs

The umbrella roof has radially-arched segmental plates with integral framing support members (usually withoutinternal support columns).

In the steel dome roof tank, the roof plates are usually formed with curved segments joined to be self-supporting.


STORAGE TANKS


3


The floating-roof tank is designed to minimize filling and breathing losses by eliminating or minimizing the vapor space above the stored liquid. The shell and bottom of this type of tank are similar to those of the fixed roof tanks, but in this case, the roof is designed to float on the surface of the stored liquid. Older styles of floating roofs include single steel deck details without annular pontoons. Such roofs have no reserve buoyancy andare susceptible to sinking in service.


STORAGE TANKS


3


Annular-pontoon and double-deck Some floating-roof tanks havefixed aluminium geodesic dome roofs installed on top of the tank shell to reduce product vapor loss or to eliminate the need to drain rainwater from the roof. These are considered internal floating roofs is a tank with a fixed steel cone roof over a floating roof.


STORAGE TANKS


3

Tanks that have cylindrical shells and cone

or dome roofs are typically used for

pressures less than about 5 lbf/in.2

(34.5 kPa) gauge. Tank bottoms may be

flat or have a shape similar to the roof.

Hold-down anchorage of the shell is

generally required.

Vapor Dome Roof

Types of Storage TanksLOW PRESSURE STORAGE TANKS

Low-pressure storage tanks are those designed to operate with pressures in

their gas or vapor spaces exceeding the 2.5 lbf/in.2 (18 kPa) gauge permissible

in API Std 650, but not exceeding the 15 lbf/in.2 (103 kPa) gauge maximum

limitation of API Std 620.

1.2 LOW PRESSURE STORAGE TANKS

1.2.1 Types of Low Pressure Tank Roofs

1.2.2 Types of Low Pressure Storage Tank Roofs

For pressures above about 5 lbf/in.2Gauge (34.5 kPa), hemispheroid, spheroid, and noded spheroid tank types are commonly used. Tanks for this application are now typically constructed as spheres. Such tanks are designed to withstand the vapor pressure that may be developedwithin a tank having no devices or means to change or relieve the internal volume. Plain Hemispheroids

3 Types of Storage TanksTYPE OF AST IN TURKEY

2. Type : Fixed Roof Tank ( Rafter&Girder supported) with/without Columns


3 Types of Storage TanksTANK FIELDS IN TURKEY

• Generally for Design and Construction Reference is API 650 or its predecessor API 12C for AST , but API 650 standard is not applied correctly.

• Tanks do not have any API monogram

• Last 10 years most of the international operators has assign Third party inspections for manufacturing and constructions

• Design data, drawing,calculation is not available

• Most of the tanks do not have any seismic design calculation & tanks are not constructed accordingly .

• Inservice Inspections are not according to PI 653 except few Internatianal Oil&Gas companies

• API Authorized Inspector is not used for inservice inspections,

• There is no plan about sel,emergency of fire earkquake, xxxxx

• Most of the field ,tank distance is according to turkish Regulations, but it is not according to NFPA.

• Fire fighting system is available but not proper, there is no risk assesment

• Almost %50 percentage of tanks do not have annular plate,

• Foundation of tanks, used sand , geographic search is not proper.

• Improper earthing connections,

• Generally painting and rarely sacrifical metal used for cathodic protection


3 Types of Storage TanksTANK FIELDS IN TURKEY

• Stairs and walk wayy are directly welded to tank,

• Thickness of shellplate is according to API 650&653 for shell and roof plate

• Poor welding quality specially 10 years and older tanks,
