Engineered pipe supports (with Structural Steel). 

In industrial reaction engineering the simplest reactors are designed like tubes or pipes, and even the more complex reactor designs are often idealized as tubes to ease the modeling complexity. Therefore, before we proceed on the CFD related modeling issues the idealized or approximate engineering pipe velocity formulas are given as they are still very useful for simple hand calculations.

GRP pipe can be generally categorized as commodity pipe and custom pipe. Both types of pipe have relative merits and fit into different niches within the GRP pipe market. Commodity pipe is made in select sizes up to about 48 in. (but normally 36 in. is the limit). Custom-engineered pipe can be made in virtually any size. Pipe 12 ft in diameter is not uncommon. 

As reviewed, the mechanical properties of centrifugally molded pipe and 55° filament wound pipe are much more resin dependent than typical custom engineered pipe. With centrifugally cast pipe, the tensile properties are very resin dependent because the fibers are chopped into relatively short lengths. It is subjected to creep and time-loss of mechanical properties. In addition, resin properties drop radically with temperature especially near the glass transition temperature.
