The material is specially formulated to result in a structurally and chemically optimized product. The resin system employed is a Bisphenol-A based epoxy resin heat cured with an aromatic amine based hardener; this formulation produces the highest mechanical strength, thermal resistance and corrosion resistance of all commercially available resin systems used in fabrication of fiberglass piping.
Green Box® product consists of our Yellow Box® product with an additional ½ mm (0.02”) thick inner resin rich liner for enhanced chemical resistance. Green Box can also be called Yellow Box® with Liner)
GREEN BOX® pipe is only available with Integral Joint (IJ) connection type and with a maximum nominal size of 10”S (pipe inner diameter 225 mm).
GREEN BOX® line pipe can be supplied with API specification 15HR monogram (specification for high pressure fiberglass line pipe) under an API license. To ensure their long term performance, the design basis is verified using long term testing and regression analysis as per ASTM D2992, at the required design temperature or higher.
