14.Q2. A welded pressure vessel made of P-No. 1 Gr. No. 1 or 2 material has welded joints in the thickness range 1 > t 1. Per Note (2)(b) of Table UCS-56 in ASME Section VIII, Division 1, the Manufacturer elects to preheat the joints during welding to a temperature of at least 200 F to avoid having to postweld heat treat the vessel. Subsequently it is decided to postweld heat treat the entire vessel according to the requirements of Table UCS-56. May the Manufacturer apply the 30F reduction in the MDMT permitted by UCS-68(c) to this vessel.

The implementation of Table UCS-68(c) is not applicable in the construction of small (1 &dbl; t 1 &2&dbl;, 1 &dbl; t 1) pressure vessels. This is because the maximum thicknesses permitted by Table UCS-68(c) are designed to accommodate processing equipment with a nominal diameter of at least {open_quote}4⁄&quote;.

The maximum thicknesses permitted by Table UCS-68(c) may also be exceeded if the pressure vessel has a nominal diameter of more than 4⁄. For example, a vessel with a nominal diameter of 20⁄ would not have been considered for Table UCS-68(c) because the maximum thicknesses allowed for a vessel of this size are limited to 16⁄ (see Table UCS-56).

(f) An unlicensed person who has filed an application with the Bureau of Boiler and Pressure Vessel Compliance and who is employed as an engineer on a certification issued pursuant to this chapter shall be exempt from the provisions of this chapter. All other unlicensed persons who have registered for a trade license shall not be exempt from the provisions of this chapter. Upon being employed by a person whose certified engineer is employed on a certification issued pursuant to this chapter, a person so employed shall be exempt from the provisions of this chapter.

D. COMPRESS does not contain the pressure rating of a vessel; rather, it contains the volume capability of the vessel, i.e., the amount of material that the vessel will accommodate. Volume capability is measured in cubic inches. Hence, we cannot, for example, tell you how many cubic feet of steel, iron or concrete a certain vessel volume can hold. However, COMPRESS allows you to determine how much material a vessel can hold based on its volume (in cubic inches) and its dimensions. If a vessel has a listed limit on the maximum pressure it is designed to withstand, you can use COMPRESS to determine the maximum volume that will be within the vessel if the maximum pressure is utilized. This calculation may be used to determine what amount of material is required for a certain volume of a vessel with a given pressure limit to meet the maximum volume specification. In the example above, the maximum working pressure is 200 kilopascals, and a vessel that must be able to withstand pressures up to 200 kilopascals has a rated maximum volume of 26,000 cubic inches. If the vessel is 4 inches in diameter by 6 inches high, you would calculate the maximum volume of the vessel to be 26,000 cubic inches by 4 X 6 or 216 cubic inches or 0.456 cubic foot. A vessel that is 4 inches in diameter by 5 inches high would have a volume of 19,744 cubic inches or 416 cubic inches or 1.66 cubic feet. The volume of the 4 inches by 6 inch by 13.5 inch deep vessel would be 139.8 cubic inches or 2.9 cubic feet.
8. A pressure vessel is filled with a material that is chosen to withstand the pressure, usually metal, concrete, wood, or plastic. Pressure vessels must withstand pressure in one of two ways: in the air spaces between the layers of material, or by balancing the weight of the layers with the weight of the material itself. The pressure vessel or bladder has two kinds of pressure-holding surfaces. One type contains a material that is stronger than the working material, thus ensuring the pressure-holding capability of the vessel. The second type of pressure vessel is an “equilibrated” container, which balances the pressure by equalizing the pressure on the inner surface of the container with the pressure on the working material, i.e., the pressure in the pressure vessel is equal to the maximum pressure to which the material can be subjected. The proper selection of material for a pressure vessel is determined by the application for which it is being used. The material most commonly used in pressure vessels is a special type of carbon steel called “canister or hydraulic grade steel.
