Of these four, the mild steel welded tank is the most popular and is widely used for every type of application. [Pg.250]

These requirements do not apply to large field-erected storage tanks covered by the Standard for Welded Steel Tanks for Oil Storage, ANSI/API 650, or the Specification for Field-Welded Tanks for Storage of Production Liquids, API 12D or to the Specification for Shop-Welded Tanks for Storage of Production Liquids, API 12F.

Tank and pressure vessel standards have limited the 1-1/2-inch maximum thickness for welded tanks and pressure vessels, without postweld heat treatment, for many years. This limitation also recognizes the decreased notch toughness in thicker plates compared to thinner plates of the same steel specification. [Pg.151]

Because of their structural integrity and ease of installation, welded tanks have become the preferred construction. The use of bolted tanks is limited to the following situations ... [Pg.480]

Storage volume requirement is greater than can be provided by welded tanks. [Pg.480]

Welded tanks require a clear site access for tank delivery and installation. The process is relatively simple, with the crane lifting the tank and setting it in place in the proper orientation. Ladders are usually installed prior to tank erection, while guardrails, crossovers, level switches, and other accessories are installed after erection in order to prevent their damage. A single welded steel silo can be erected, have its accessories attached, and be ready for filling in as little as 4 to 6 h. [Pg.481]

Welded tanks may be finish painted at the factory with almost any desired color. All that is required in the way of field finishing is minor touch-up of scratches which may occur during erection. [Pg.482]

Note One limitation on welded tanks is the size which can be shipped over the road. Currently, the maximum size is 14 X 12 ft overall height (OAH). Bolted tanks have no such limitation. [Pg.483]

Tank storage is broken down into different areas such as welding tank storage and the different types of tanks. Specifications are also given in this subpart on how the tanks should be built. Each tank is required to have certain values that regulate the pressure in the tanks. Tanks are to be stamped or marked with the material the tank is holding. Finally, inspection of these tanks is required in order to prevent an accident from happening. [Pg.430]

The second set of numbers is the marked test pressure of the tank, 300 psig (2068 kPa) in the example TC/DOT-105A300W. The last letter, or set of letters, gives information about the tank material and the method of fabrication. The letter W, in the example, indicates a steel fusion-welded tank. If the letters were ALW, it would indicate an aluminum fusion-welded tank. The letter X would signify a tank with a fusion-welded longitudinal seam and forge-welded head seams. If the suffix letter is F, it denotes a forge-welded tank. [Pg.51]

The principal factor, which determines the thickness of the tank shell, is the internal loadings due to the liquid head. The minimum acceptable thickness for welded tank shells may be calculated from the following formula used in BS2654 and in EEMUA 159 for the basic design of tank shells ... [Pg.2250]

Fully austenitic filler metals should therefore be welded with low heat input. Because the filler metal generally has lower trace element contents than the parent metal, the risk of hot cracking will be reduced if a large quantity of filler metal is fed down into the weld pool. Because the weld metal contains no ferrite, its impact strength at low temperature is very good. This is important to manufacturers of, for example, welded tanks used to transport cryogenic liquids. [Pg.719]

It is used for the manufacture of welded tanks for space launcher rockets. [Pg.66]

Welded tanks are preferable to those riveted or bolted. [Pg.321]

Standard tank dimensions are listed in API Specification 12F (Shop Welded Tanks), API Specification 12D (Field Welded Tanks), and API Specification 12B (Bolted Tanks). These dimensions are shown in Tables 1.1, 1.2, and 1.3, respectively. [Pg.6]
