Unfired pressure vessels

ASME Boiler and Pressure Vessel Code. The ASME Boiler and Pressure Vessel Code is pubhshed in 11 sections. Section VIII, which is concerned with rules for the design of unfired pressure vessels, was first pubhshed in 1925 and since 1968 it has been issued in two parts. Division 1 (147) and Division 2 (148), the latter being known as the Alternative Rules. 

Pressure- Vessel Standards. Explosion-clad plates for pressure vessels are tested according to the appHcable ASME Boiler and Pressure Vessel Code Specifications. Unfired pressure vessels using clads are covered by ASTM A263, A264, and A265 these include tensile, bend, and shear tests (see Tanks AND pressure vessels).

C = ASME Unfired Pressure Vessel Code constant for a vapor as described above, C is a function of the specific heat ratio, K. The equation given earlier for determining C is expressed in tabular form in Table 2. 

Note that for fired boilers, where the safety valve installation must comply with the ASME Code for Power Boilers rather than the code for Unfired Pressure Vessels, the allowable accumulation is only 6% instead of 10%. Reference also should be made to the Kj and A definitions, above.

An abbreviated listing of the key rating provisions is given in paragraphs UG-125 through 135 of the ASME code, Section 8, Div. 1, for unfired pressure vessels [1].

Meeting all A.S.M.E. Unfired Pressure Vessel Code requirements, the 80-10" Head permits significantly higher pressures than other configurations selected for the same service. The 80-10 " Head is named for its unique dimensions—the dish radius equals 80% of the head diameter and the inside corner radius equals 10% of the head diameter. These dimensions compare to 100% and 6% respectively for A.S.M.E. F D Heads. 

The American Society of Mechanical Engineers (ASME) Unfired Pressure Vessel Code is accepted by almost all states as a requirement by law and by most industrial insurance underwriters as a basic guide or requirement for fabrication of pressure vessel equipment, which includes some components of heat exchangers.

Unfired pressure vessels should be designed and constructed in accordance with Section VIII, Division 1 or Division 2, of the ASME 6o 7er and Pressure Vessel Code.

Storage tanks should be designed in accordance with the ASME code for unfired pressure vessels. All-welded construction is recommended. Ethylene oxide storage tanks should be electrically grounded, isolated from potential fire hazards, and equipped with pressure relief devices. New equipment should be cleaned of iron oxide and immediately puiged with inert gas. 

The mechanical design of the column incorporates three main stages. The first specification is for the materials of construction. Second, the shell and head thickness must be chosen in order to withstand the operating conditions and also extraneous forces. Finally, consideration of the construction and assembly. The design was performed according to the relevent Australian Standard, AS1 210 SAA Unfired Pressure Vessels Code (Ref. Al 0).

These codes provide all the rules for the design, fabrication, testing, materials and certification of boilers and unfired pressure vessels. The rules include requirements for the pressure-relieving devices to be installed on every boiler or other pressure vessels.
