Sweepolets are primarily developed for high-yield pipe used in oil and gas transmission lines. Sweepolets provides good flow pattern, and optimum stress distribution. Sweepolet is a contoured, integrally reinforced, butt-weld branch connection with a low stress intensification factor for low stresses and long fatigue life. The attachment weld is easily examined by radiography, ultrasound and other standard non-destructive techniques. They are manufactured to meet specific reinforcement requirements.
