ASME PTB 4 Section VIII - Division 1 Example Problem Manual

1.1 Introduction

ASME B&PV Code, Section VIII, Division 1 contains mandatory requirements, specific prohibitions, and non-mandatory guidance for the design, materials, fabrication, examination, inspection, testing, and certification of pressure vessels and their associated pressure relief devices.

1.2 Scope

Example problems illustrating the use of the design-by-rule methods in ASME B&PV Code, Section VIII, Division 1 are provided in this document. Example problems are provided for most of the calculation procedures in either SI or US Customary units.

1.3 Definitions

The following definitions are used in this manual.

• VIII-1 – ASME B&PV Code, Section VIII, Division 1, 2010 Edition, 2011 Addenda

• VIII-2 – ASME B&PV Code, Section VIII, Division 2, 2010 Edition, 2011 Addenda

1.4 Organization and Use

An introduction to the example problems in this document is described in Part 2 of this document. The remaining Parts of this document contain the example problems. All paragraph references without a code designation, i.e. VIII-1 or VIII-2, see Definitions, are to the ASME B&PV Code, Section VIII, Division 1, 2010 with the 2011 Addenda [1].

The example problems in this manual follow the design by rule methods in ASME B&PV Code, Section VIII, Division 1. Many of the example problems are also solved using ASME B&PV Code, Section VIII, Division 2 design-by-rule procedures contained in Part 4 of this Code using the allowable stress from VIII-1. In addition, where the design rules are the same, the VIII-2 format has been used in this example problem manual because of the user-friendliness of these rules.

1.5 Comparison of VIII-1 and VIII-2 Design Rules

Since many of the design rules in VIII-2 were developed using the principles of VIII-1, it is recommended that users of this manual obtain a copy of ASME PTB-1-2009 [2] that contains the VIII- 2 criteria and commentary on the technical background to these rules. A comparison of the designby- rule procedures in VIII-2 compared with VIII-1 is shown in Table E1.1. 1.6 ASME Code Case 2695

In recognition of the similarities and the use of the latest technology in developing the design-by-rule part of VIII-2, ASME has issued Code Case 2695 that permits the use of VIII-2 design rules with VIII-1 allowable stresses with some limitations. Code Case 2695 is shown in Table E1.2.
