This guide provides information and recommendations for design professionals, fabricators, installers and end-users of FRP chimney liners. FRP is a cost-effective and appropriate material of construction for liners operating at moderate temperatures in a corrosive chemical environment.

This guide provides uniformity and consistency to the design, fabrication, and erection of fiberglass-reinforced plastic (FRP) liners for concrete chimneys with coal-fired units. Other fossil fuels will require a thorough review of the operating and service conditions and the impact on material selection.

This guide is limited specifically to FRP liners within a supporting concrete shell and is not applicable to other FRP cylindrical structures.

1.1 This guide offers direction and guidance to the user concerning available techniques and methods for design, material selection, fabrication, erection, quality assurance, and control.

1.2 These minimum guidelines, when properly used and implemented, can help ensure a safe and reliable structure for the industry.

1.3 This guide offers minimum requirements for the proper design of a FRP liner once the service conditions relative to thermal, chemical, and erosive environments are defined. Due to the variability in liner height, diameter, and the environment, each liner must be designed and detailed individually.

1.4 Selection of the necessary resins and reinforcements, composition of the laminate, and proper testing methods are offered.

1.5 Once the material is selected and the liner designed, procedures for proper fabrication of the liner are developed.

1.6 Field erection, sequence of construction, proper field-joint preparation, and alignment are reviewed.

1.7 Quality-assurance and quality-control procedures are developed for the design, fabrication, and erection phases. The quality-assurance program defines the proper authority and responsibility, control of material and fabrication, inspection procedures, tolerances, and conformity to standards. The quality-control procedures provide the steps required to implement the quality-assurance program.

1.8 Appendix X1 includes research and development subjects to further support recommendations of this guide.
