Abstract
An improved protective jacket for insulated, angled pipe includes a metal jacket having a first portion and a second portion, each portion having a generally semi-circular cross-section, and including two or more fingers. Each of the fingers defines a fillet at a junction of the fingers and a baseline of the jacket. The fingers include a flat face at an inner angle and curve from the flat face to a superior surface of the jacket. A first finger is formed a minimum distance of about 0.5 inches from a second finger, and a width of the fingers is created by an isosceles triangle with a radius of curvature between about 0.3 inches and 0.5 inches.
