ELBOW SLEEVES

EngRx has developed a line of steel repair sleeves for standard butt weld elbow type fittings. The sleeve is a pressure retaining weld-on type, similar to “Type B” straight line repair sleeves. The purpose of the sleeve is to repair defects consistent with in-service piping elbows, such as internal/external erosion & corrosion, dents, gouges, pinholes, or weld defects. The sleeves are designed to be installed while the damaged line is active or live.
