3、 This practice establishes procedures for the burial ofpressure and nonpressure“fiberglass”(glass-fiber-reinforcedthermosetting-resin)pipe in many typically encountered soilconditions.Included are recommendations for trenching,plac-ing pipe,joining pipe,placing and compacting backfill,andmonitoring
4、deflection levels.Guidance for installation offiberglass pipe in subaqueous conditions is not included.1.2 Product standards for fiberglass pipe encompass a widerange of product variables.Diameters range from 1 in.to 13 ft(25 mm to 4000 mm)and pipe stiffnesses range from 9 to over72 psi(60 to 500 kP
