Where impact or vibration are recognized as unavoidable in plant start-up, shut-down, or normal operation, then pipe restraints, snubbers, and controls shall be employed to eliminate detrimental effects on the piping and restraints.
As part of the materials listing, the Code includes allowable casfi values as a function of design temperature, and some helpful notes relating to material behavior under various service conditions [Tables A-1 and A-2, and Appendix F].

This is not to say, however, that designers who are capable of applying a more rigorous analysis should be restricted to this simplified approach. They are failure curves, not design curves. Consequently, the objective of this chapter is to explore the basic technology behind some of the special processes in relation to requirements of the Code.
However, changes to direction of flow may also be made through the use of pipe bends.

However, there is one consideration for which the explanation should be expanded. These installations are similar to refining or processing plants in their property requirements and include: Castj requirement is mainly of a practical nature and aims to avoid any work constraints imposed by the restricted access or interference created by repads or saddles.
Impact caused by water hammer or guivebook equivalent of steam hammer should be eliminated as much as possible with piping layout and valve selection particularly check valves. Progressive examination is included as a type of examination, even though it is only used when defects are revealed by spot or random examination. Rather, the user should be looking at more global issues including resistance of generic material groups to various forms of corrosion, material cost and availability for various product forms, delivery times, need for qualification testing, and existence of suitable forming and joining technology.

Design temperature method of determination other than fluid temperature is permitted provided this temperature is established by heat transfer calculation procedures consistent with industry practice. The metric equivalent of this procedure was not available at the time of this writing.
A vibrating piping system see Figure 2. Primary Quality Management Function: The nominal pressure stress hoop stressshall not exceed the yield strength of the material at temperature. Scope As seen in the preceding section, codes originated in response to numerous boiler explosions resulting from unsafe design and construction practices.
We would like to hear from guieebook. An uninformed user could end up searching through the approximately 50 pages of information constituting B Rather than base the design pressure and temperature on these short term operations, the Code provides conditions to permit these variations to occur without becoming the basis of design. Therein, the Code sets the first two allowable stresses for design: The preceding discussion of Table A-1 may appear simplistic, especially if you work with many different systems on a regular basis.

Sc and Sh are the basic allowable stresses for the cold and hot conditions as defined in the Defintion and Basis for Allowable Stress section in Chapter 1. The f factor although appropriate for the 18, cycles of this problem, is also suitable for 22, cycles as shown in Table When Must the Items Be Examined? The answers to two questions could be helpful in selecting the governing code section: Grades are described in terms of several standardized alphanumeric designation systems that depend upon the alloy system under consideration, and are described later in this chapter.
When the plant owner designates a piping system to be high pressure, all the requirements, Chapter IX of B Pressure Design of Piping Components Wall Thickness for Straight Pipe under Internal Pressure The most significant deviation from the base Code is in the equations for determining the wall thickness requirements for internal pressure. Material Classification Systems and Specifications The language of materials can be complicated.

Inspection Versus Examination Under B A lesser reliability can be tolerated in B Grover Shoe Company plant Figure 1. In addition, prohibitions and warnings about unsafe designs and practices are also included. It is with this edition that Guidbeook It is the owners responsibility to specify the fluid service category for each piping system.
The key components of the design conditions are the design pressure and the design temperature. The allowable stress range is presented in B
