Yellow Box™	Text size: a a a

Pressure & diameter range | Joining system & lengths | Advantages YELLOW BOX® line pipe is a machine-made composite material produced by filament winding high strength continuous glass fiber filaments and corrosion resistant epoxy resin, especially formulated to result in a structurally and chemically optimum product. The epoxy resin is an aromatic amine, heat cured system that has the highest mechanical strength, thermal resistance and best corrosion resistance of all commercially available resin systems used in the fabrication of fiberglass piping.

De-rating required for operating temperatures above 150°F [top] JOINING SYSTEM & LENGTHS Field assembly of threaded joints YELLOW BOX pipe products are connected with the reliable, time proven integral joint API 8-round external upset end (EUE) long threaded connections up to 4" size, and with casing long and casing short threaded connections for the larger sizes. Filament wound threaded couplings are utilized for the connection of sizes 8" and larger. All sizes are supplied in standard or L.F. (9.14 m ) laying lengths. YELLOW BOX pipe is offered with a complete line of fittings including elbows, tees, couplings and flanges in most sizes and pressure classes. YELLOW BOX is a high pressure, filament wound glass reinforced epoxy (GRE) line pipe with threaded joints used mainly for crude flow lines and flood water injection lines. [top] ADVANTAGES Manufactured from Aromatic-amine, heat-cured epoxy resin which provides the highest combination of mechanical and chemical resistance for GRE pipe systems. Suitable for operating temperatures up to 212°F (110°C) No external corrosion from aggressive soils and ground water No internal corrosion from saline or brackish flood water or high-water cuts No maintenance, painting, or cathodic protection is required 20 Year design life Low friction losses ( "C" factor = 150 ) and low life cycle costs Light weight, easy and fast installation Water tight threaded joints (API 8 rnd).
