Basics of Piping System Thermal Expansion for Process Engineers

William N. Weaver, P.E. and John C. Huang, Ph.D., P.E.

Course Outline

This material provides a basic understanding of thermal expansion in piping systems. Calculations are provided with an explanation of terms used. Causes of pipe expansion are explored providing the engineer with a basic knowledge suitable for ensuring expansion problems do not develop in his designs or facility. A commonly used ASME test for pipe stress is introduced with calculations and techniques to correct expansion caused stresses in piping systems.

This material consists of five parts designed to provide the engineer with a basic understanding of thermally induced pipe expansion. Those parts are:

A brief discussion of shrinkage of pipes is included along with tables of thermal expansion coefficients and references.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

On completion of this course material the student should:

Intended Audience

This course material is intended for Process Engineers, Piping Engineers, Maintenance Engineers and Construction Engineers. Engineering Manager with review responsibility will also benefit.

Benefits to Attendee

Engineers completing this course material will be better prepared to evaluate piping system designs and installations. The basic understanding of thermal expansion is essential to proper piping system design and approval. The Construction or Maintenance Engineer will benefit in that a walk down review of installed piping will now include thermal expansion concerns.

Course Introduction

This course is designed to provide the engineer with sufficient information and training to evaluate pipe expansion problem in design drawings and in field installations. Those responsible for piping systems will have a basic understanding of the available solutions for thermally induced pipe expansion.
