ENGINEERED RESPONSE PRODUCT DESCRIPTION: LOW SALINITY DISSOLVABLE ALLOY TervAlloy™ 1331 is the latest freshwater low temperature version of Terves’ patented dissolvable magnesium for oil and gas applications. This new alloy successfully bridges the gap between existing low salinity alloys and true freshwater-dissolvable alloys. TervAlloy 1331 is unique in that it has the dissolution characteristics of our TervAlloy 1530 (FW), but unlike 1530, is available in both tubulars and solids, and offers mechanical performance not only superior to our 1530 product. TervAlloy 1331 can be purchased in the same variety of shapes offered across the TervAlloy range (including cost-saving tubulars) in lengths up to 48 inches (in increments of 6 inches), and also in frac ball configurations up to 4.95 inches in diameter.
