Double-Socket Collar Repair Clamps for D.I. Pipeline

Product Overview

In ductile iron water supply and sewage systems, leaks occurring at the joints of a double-socket collar—where two spigot ends meet—require a specialized and highly reliable solution. Metalsin’s custom-engineered Double-Socket Collar Repair Clamp is specifically designed to address these critical failure points with maximum efficiency. This “wrap-around” repair technology enables rapid emergency intervention while the pipeline remains under pressure, effectively eliminating the need for service interruptions or costly pipe replacements. It serves as an essential tool for maintaining municipal infrastructure, providing a high-strength, permanent fix for joint leaks in even the most demanding environments.

The use of double-socket collar repair clamp in ductile iron pipelines.

Built for long-term durability, the repair joint features a robust two-piece body manufactured from high-grade ductile iron, compliant with international standards such as ASTM A536 or EN 1563. The unit is equipped with high-performance EPDM or NBR rubber gaskets that create a compression-based, leak-proof seal while adhering to strict potable water hygiene standards like NSF/ANSI 61 and WRAS. A key technical feature is the integrated malleable iron vent plug, which allows for pressure relief and air discharge during installation to ensure the gasket seats perfectly against the pipe surface. Secured by high-tensile stainless steel or galvanized carbon steel bolting materials, the double-socket collar repair clamp offers superior corrosion resistance and proven performance through rigorous hydrostatic testing.
