When the design temperatures are significantly below ambient temperature, the primary threat to tank integrity is failure of the material by britde fracture. The tank design codes usually provide thorough treatment of this topic to prevent catastrophic failure. Additionally, there is the consideration of corrosion allowance, defined as extra thickness added beyond that required for strength. Corrosion allowance is not discussed herein. 

Modern-day piping design codes can model the vibration situation, and problems can thus be resolved in the design phases.

Eigures 10-lA-G and Table 10-1 from the Standards of Tubular Exchanger Manufacturers Association give the nomenclature of the basic types of units. Note the nomenclature type designation code letters immediately below each illustration. These codes are assembled from Table 10-1 and Eigures 10-lA-G.

The hydraulic design is described by two components the type of fluid outlet and the flow distribution. A 3 x 3 matrix of orifice types and flow distributions defines 9 numeric hydraulic design codes. The orifice type varies from changeable jets to fixed ports to open throat from left to right in the matrix. The flow distribution varies from bladed to ribbed to open face from top to bottom. There is usually a close correlation between the flow distribution and the cutter arrangement. 

A special case is defined the numbers 6 and 9 describe the crowfoot/water course design of most natural diamond and many TSP bits. Such designs are further described as having either radial flow, crossflow (feeder/collector), or other hydraulics. Thus, the letters R (radial flow), X (crossflow), or O (other) are used as the hydraulic design code for such bits. 

Figure 4-164 shows a steel body core bit with a long-taper, stepped profile fitted with impregnated natural diamond blocks as the primary cutting elements. The bit has no inner cone. Since there is no specific code for the natural diamond/steel body combination, the letter O (other) is used as the cutter type/ body material code. The profile code 3 is used to describe the long outer taper with little or no inner cone depth. The hydraulic design code 5 indicates a fixed... 

The various components which make up a shell and tube heat exchanger are shown in Figures 9.63 and 9.64 and these are now considered. Many different mechanical arrangements are used and it is convenient to use a basis tor classification. The standard published by the Tubular Exchanger Manufacturer s Association (TEMA 97 ) is outlined here. It should be added that noting that Saunders 98 has presented a detailed discussion of design codes and problems in fabrication. 

The pressure vessel design codes and standards include lists of acceptable materials in accordance with the appropriate material standards. 

The corrosion allowance is the additional thickness of metal added to allow for material lost by corrosion and erosion, or scaling (see Chapter 7). The allowance to be used should be agreed between the customer and manufacturer. Corrosion is a complex phenomenon, and it is not possible to give specific rules for the estimation of the corrosion allowance required for all circumstances. The allowance should be based on experience with the material of construction under similar service conditions to those for the proposed design. For carbon and low-alloy steels, where severe corrosion is not expected, a minimum allowance of 2.0 mm should be used where more severe conditions are anticipated this should be increased to 4.0 mm. Most design codes and standards specify a minimum allowance of 1.0 mm. 

Values for the design constant Cp and the nominal plate diameter De are given in the design codes and standards for various arrangements of flat end closures. 

The equal area method is the simplest method used for calculating the amount of reinforcement required, and is allowed in most design codes and standards. The principle used is to provide reinforcement local to the opening, equal in cross-sectional area to the area removed in forming the opening, Figure 13.13. If the actual thickness of the vessel...

Operating errors. Many vessel collapses have resulted from closing or failing to open a valve in a vent line. For this reason, valves in vacuum relief lines should be avoided, and they may be prohibited by some design codes. 

Wet and dry pipe sprinklers are not functionally tests for coverage since design codes have eliminated problems with distribution patterns, provided the installation has been adequately inspected. The normal testing verifies adequate pressure is available, piping is not plugged and activation of alarms occurs. 

To achieve it, you must employ certain techniques in your design. For example, if you forget to include a stout metal case around the outside, your assets will monotonically decrease people can get directly at the cans (and any cash that others may have been foolish enough to insert). Similarly, the developer of an alphabetically sorted list of customers cannot guarantee that the list will remain sorted if other designers code can directly update customers names. You can guarantee only what you have control over.
