90°-Elbow Repair Clamp for Steel Pipes

January 8, 2026

Product Overview

Metalsin’s 90°-elbow repair clamp for steel pipes is a high-performance solution specifically engineered for the rapid containment of leaks at threaded 90-degree junctions in small-diameter (up to DN100) galvanized steel pipe systems. These pipelines commonly utilize malleable iron elbows with BS 21 internal threads to facilitate right-angle directional changes. Our clamp features a robust ductile iron “wrap-around” design that fully encapsulates the leaking 90° elbow, allowing for a permanent seal while the system remains under pressure. By eliminating the need for costly service interruptions or the labor-intensive replacement of threaded fittings, Metalsin provides a time-saving and reliable maintenance tool for municipal water supply and drainage networks.
