W V re- cently completed the materials properties test and the physical test portion of their investiga- tion under UL subject 971 and ULC C107C- M1984 of Centron fiberglass / epoxy tubular products in size 2" and found it to comply with all applicable requirements for use with petro- leum products, alcohol, and alcohol -gasoline blends. UL file MH15635 and ULC file CMH 1301. 0 ® fiberglass / epoxy tubular products have the same excellent corrosion and physical properties as the CentronO Oil Field products. The pipe, sleeve couplings, adapters, and reducer bushings are manufactured using the same filament winding process that has produced field proven tubular products for the past fifteen years. These products have been used by major and independent oil companies in service condi- tions up to 3,500 psi. El - Centron@ fiberglass /epoxy tubular products are lightweight, easy to handle and instaff, and well suited for installation in underground fuel service piping systems and transmission lines. The bell and spigot piping systems are installed using Centron R CAS -1 fuel and alcohol resistant adhesive specifically de- signed fbr this application. This adhesive was de- veloped for rapid installation with short cure time and maximum durability. Assembly of'Cen- tron(k) piping syhtems requires no special field 2 0 Preparation except for tapering of field cut joints which is fully outlined in our instarllrrtion instrtrc- tians. A full range of fittings and adapters are available. Q - CentronO fiberglass /epoxy Pipe products are filament wound on polished steel mandrels. The angle of the continuous fiberglass roving is precisely controlled to give th' tIIhL11 (r [woducts maxinlrlrrr pc3rfcn m,incc capabilities. The epoxy resin matrix used in Centron rr fiberglass / epoxy products determines the mechanical, chemical, and thermal proper- ties of the products. The composite has a glass - to -resin ratio of 75:25 by weight and the glass/ resin system is matched for optimum physical and chemical resistance. The chemistry of the epoxy resin mix is strictly controlled and the curing cycle carefully monitored to ensure Optimum chemical and physical properties of the finished product. El - Centrong epoxy fittings are the first to be manufactured using the state-of--the-art Resin Transfer Molding (RTM) technology. This process permits the LISP.

Additionally, the proprietary RTM technique used to manufac- ture CentronOO RTM fittings produces parts with very low void content, excellent fiber wet out, and a resin rich inner surface for exceptional corrosion re5istnncc. 0
