Flat laminated panels are manufactured using fluorinated sheet substrates. The manufacturing of these test panels simulates the production process used to manufacture the fiberglass-reinforced pipes. The BS6464 test prescribes a minimum adhesive shear and peel strength of 7 MPa and 7 N/mm, respectively. Representative values for both tests are given in Tables 16.9 and 16.10 below. 

In the context of corrosion, composites refer to glass or other fiber or flake-reinforced thermosetting resins. Composite products use for their anticorrosion properties are fiberglass-reinforced pipe and storage tanks, fiber-reinforced plastic grating, handrails, I-beams, and other shapes equal to these that are made of steel. 

Fiberglass-reinforced pipe has the further advantage of a smooth inner surface. Pressure drops are lower than in iron pipe of the same diameter. In a carefully fabricated and installed system, the pressure drop could be less than half that found in iron pipe. Practically, a ratio of 0.6-0.7 is more likely [28].

Because many of these systems are of PVC, carbon, stainless steel, or fiberglass reinforced pipe, the key elevations are set by working point centerlines. With the individual sublaterals, or leads, sloped to Vi in per foot, the only working point elevations required for this particular system are at the beginning or high point, at the change in direaion at the east battery... 

Concrete pipe—Used for surface drainage and for 15-in and larger pipes. Although it is available in smaller sizes, economics may limit its use. Fiberglass reinforced pipe—Used in corrosive service. It is limited to low-pressure and low-temperature systems. When fabricated, it is designed to meet very specific needs. For example, it may need to be able to withstand outdoor exposure or burying or may need to be sun retardant or made to project-specific dimensions. 

Vertical intake wells eonsist of a nonmetaUic casting [typically, fiberglass-reinforced pipe (FRP) or polyvinyl chloride (PVC)], proper-grade stainless steel well screen (if needed), and a stainless steel submersible or vertical turbine pump (see Fig. 3.2). These wells are usually less costly than the horizontal wells, but their yield is relatively small (typieaUy 400-4000 m /day).
