MARCH 2010 The FIBERBOND® Engineering Guide www.fiberbond.com www.exelisinc.com ENGINEERED COMPOSITE PIPING SYSTEMS MARCH 2010 EDITION FIBERBOND® Page 1 What is FRP? FRP was originally an abbreviation for Fiberglass Reinforced Plastic. As additional fiber reinforcements were introduced, the term has been expanded to refer to Fiber Reinforced Plastic. You may also hear of terms such as GRP (glass reinforced plastic), RTP (reinforced thermosetting plastic) and RTRP (reinforced thermosetting resin pipe). Even more specific, there is GRE (glass reinforced epoxy), GRVE (glass reinforced vinyl ester) and GRUP (glass reinforced unsaturated polyester). The list of terms seems to go on and on. What these terms do have in common is that they refer to a reinforced plastic with a thermosetting resin as the matrix. Unlike thermoplastics (such as PVC, CPVC, PE, etc.), thermosetting resins are infusible and insoluble when fully cured and thus provide better mechanical properties. Combined with the reinforcing fibers, FRP has an excellent strength-to-weight ratio while maintaining very good corrosion resistance to a wide range of media. TABLE OF CONTENTS I. Introduction II.

Appendix II: Governing Equations THE FIBERBOND® ENGINEERING GUIDE FIBERBOND® Page 2 INTRODUCTION FIBERBOND® Fiberglass and Advanced Composite Piping Systems are economical choices for use in corrosive fluid transport. The FIBERBOND® product is an alternative to stainless steels, copper-nickel, and other reinforced and non-reinforced plastics and alloys. FIBERBOND® can be used in environments at temperatures up to 250°F (121°C) and pressures up to 290psig (20barg). The information contained in this Engineering Guide is the first step towards designing the optimum FIBERBOND® Piping System. FIBERBOND® FRP Piping Systems All FIBERBOND® Piping Series use a glass-fiber reinforcement bound in a resin matrix. Together, the glass-fibers provide strength and, the resin matrix provides superior corrosion resistance. FIBERBOND® Fiberglass Piping Series are filament wound products with a winding angle of 54°. This is the principal axis of loading for internal pressure. FIBERBOND® Series 20HV, 20FR-E, 20JF, 20C, 20FR20, 20FR16, and 110FW all utilize this winding pattern. FIBERBOND® MultiAngle Pipe The FIBERBOND® MultiAngle Pipe goes one step further by incorporating advanced technology in the filament winding process. Instead of winding at the traditional 54degree pattern, MultiAngle pipe is wound at multiple angles through the use of advanced 4-axis technology. These additional winding angles are incorporated into the pipe so that other loading conditions, such as end loads, bending loads, and collapsing pressure, are taken into account. By doing so, a superior system can be designed with less material at a lower cost. Using the FIBERBOND® Engineering Guide The purpose of “The FIBERBOND® Engineering Guide” is to help the customer select the proper support spacing, guide spacing, and anchoring for an above ground piping system. Other methods to deal with the flexibility of the system, such as expansion loops, are also evaluated. In addition, “The FIBERBOND® Engineering Guide” will also allow the customer to approximate head losses and water hammer in a FIBERBOND® Piping System. Specialty Plastics is committed to supporting its customers. An engineering staff is on hand to answer all your questions or design the system with the customer. FIBERBOND® Custom Piping Systems In addition to the FIBERBOND® Fiberglass and Advanced Composite Piping Series, Specialty Plastics also offers a custom line of piping systems. FIBERBOND® custom products are pipe systems engineered by Specialty Plastics to meet individual customer specifications. By customizing the system, an optimum pipe product is produced saving the customer time and material. The custom products offered in the FIBERBOND® line are engineered, manufactured, fabricated, and installed by Specialty Plastics. Statement of Policy Standards are a recognized customer need and progress has been made in developing reliable standards for composite pipe. However, one of the major benefits of FIBERBOND® Fiberglass and Advanced Composite Piping Systems manufactured by Specialty Plastics is the ability to engineer the mechanical and physical properties to meet individual customer service requirements. Under certain conditions, industry standards, which are misunderstood and/or misapplied, become a hindrance to the development of new and improved products. It is important that the engineer working with composite pipe is aware of the limits of currently available industry standards and learns how the product is designed and manufactured. We feel it is important that the engineer designing a FIBERBOND® Piping System has a working knowledge of how the raw materials interact to provide the chemical resistance and the mechanical properties of the pipe. Once the engineer understands these basic principles, he or she can truly appreciate the flexibility FIBERBOND® Piping Systems offer in solving difficult corrosion piping problems at the lowest possible cost. The information in the FIBERBOND® Engineering Guide covers the design of Series 20HV, 20FR-E, 20JF, 20C, 20FR16, 20FR20, and 110FW. It is our mutual interest that the FIBERBOND® Piping System selected meets the customer’s design criteria and is installed at the most economical cost within the guidelines set forth by this engineering guide and other industry standards. The success of your installation is important to our company…after all, our future depends on it. MARCH 2010 EDITION FIBERBOND® Page 3 SUPPORTING FIBERBOND® PIPING SYSTEMS Supports are designed into a piping system to prevent excessive deflection due to the pipe and fluid weight. When the mid-span deflection is limited to 0.5 in., the bending stress on the pipeline is normally below the allowable levels of the pipe and fittings. However, in designs that are more stringent it may be necessary to use shorter spacing. This can be true if there are a number of heavy in-line components, such as valves, in the system, or if the design pressure and/or temperature are near the product limits. Once support spacing is calculated, the maximum stress levels should be determined. Support conditions are defined as Type I, II, III, or IV. The standard commonly used is the Type II condition in which the pipe spans two or more supports. The Types I, III, and IV conditions refer to single-span, triple-span, and fixed-ends, respectively. For very short runs and anchor locations, these conditions should be considered. Refer to the Support Types diagram for the Types I, II, III, and IV support conditions. Above 150°F, the support spacing may have to be degraded per the Temperature Correction Factors Table to account for the lower modulus values.
