Although bolted joints comprise a large percentage of all industrial fasteners, their role in the installation and assembly process is poorly understood.  This course provides an overview of bolted joint fundamentals, and focuses on the roles of bolts and gaskets in developing and maintaining leak-tight connections of bolted flange joints, including troubleshooting of existing bolted flange connection.

This course examines how to assess a successful value of bolt load, as well as explains the importance of specifying a tightening procedure.  It introduces the subject of PVRC leak tightness calculations and presents an overview of current trends and practices to achieve reliable leak-tight bolted joint solutions.

Each participant will receive a copy of the book, An Introduction to the Design and Behavior of Bolted Joints, 3rd Edition, by John Bickford.

You Will Learn To:
 - Explain how the bolted joint functions as a mechanical system that relies each of its basic components to successfully seal the connection
 - Assess the mechanical stress and strain of a bolt and explain the challenges that one encounters when specifying an optimum bolt load
 - Describe the effects of in-service conditions and how they reduce or increase bolt load
 - Describe the concept of leak-tightness as a predictable value of gasket stress and how to use leak tightness as the basis of specifying bolt loads
 - Identify conditions that create bolt failure
 - Explain the general scope of the PCC-1 Joint Assembly guidelines and how compliance promotes successful sealing of bolted, gasketed connections
 - Evaluate bolting torque and explain how to use it to develop maintenance procedures

Course Requirements
Attendees are required to bring a scientific calculators to class to complete exercises.

Who Should Attend
Engineers with the responsibility for, or are involved in the specification and assembly of bolted joints and gasketed bolted flange connections. Two years of engineering experience would be beneficial, but is not required. 

This course is an excellent prerequisite to PD386, “Design of Bolted Flange Joints”

Save up to $1,440 by enrolling in PD601, a triple combination course consisting of this course (PD539), PD577 "Bolted Joint Assembly Principles Per PCC-1 - 2013," and PD386 “Design of Bolted Flange Joints.”

Randy Wacker, P.E., has over 35 years of experience in the design, specification, maintenance and troubleshooting of process equipment. This includes working in various capacities for over 20 years in three DuPont Petrochemical Plants, and an additional 13 years as a consultant in the DuPont Engineering Technology, Process Equipment Group.

Mr. Wacker is currently the Senior Consultant for Inertech, Inc., where he provides PVRC leak-tight gasket solutions for bolted flange connections and a wide range of process equipment. He is a committee member of the ASME Special Working Group for Bolted Flange Connections, ASME RTP-1 FRP Committee, ASTM F03 on Gaskets, the SAE AMS Aerospace G9 Committee on Sealing, and spent over seven years as member of the NBIC (National Board Inspection Code). He is also a member of the European Sealing Association (ESA), the Fluid Sealing Association (FSA), and is a founding member of the Advisory Group that developed the training program for ASME PCC-1 Bolting Specialist Qualification. Mr. Wacker has authored ASME PVP 2008-61410 (finite element analysis for the PVRC BFJ committee), and has recently published 10 magazine articles that discuss various sealing considerations for bolted flange connections.
