Introduction:
When investigating the use of fiberglass reinforced plastic (FRP) pipe in the chemical, petrochemical, marine,
and other industries, several decisions have to be made early on in the design of the piping system. These
include the pipe fabrication technique (filament winding vs hand-lay up, for example), the method of installation
(flanged pipe vs plain end pipe, and field-fabricated vs shop-fabricated spools), and the joining system
(adhesive-bonded vs butt and strap, for example), to name a few.
The engineering that must be performed in the design stage of the project is critical to all future phases of the
project. Engineering services include design calculations, piping stress analyses, piping support drawings,
piping orthographic drawings, piping isometrics, and shop fabrication spool drawings. Each type of service
offers different information to different parties. Engineering information is of value to designers, draftsmen,
project engineers, purchasing agents, mechanical contractors, manufacturers, and subcontractors. Each party
requires different types of engineering services depending upon his role in the project. This report will give a
description of each type of the various engineering services available and where these services are typically
employed.
