Butt-Fusion-Welding joint Repair Clamp for HDPE Pipes

December 28, 2025

Product Overview

Metalsin’s butt-fusion-welding joint repair clamp for HDPE pipes is a specialized solution engineered for the emergency repair of leaks occurring at fused joints in water supply and wastewater systems. Butt-fusion welding is a premier connection method that melts pipe ends to create a joint as strong as the pipe itself, making it the standard for high-pressure and large-diameter HDPE applications. When a leak occurs at these critical fused beads, this repair clamp provides an essential “wrap-around” repair that restores joint integrity without compromising the pipeline’s overall performance.

Designed for maximum operational efficiency, this ductile iron repair clamp enables rapid, in-service repairs while the system remains under pressure. This eliminates the costly necessity of shutting down the entire line or performing complex pipe replacements. Metalsin’s BFW joint repair clamp is precision-engineered to fit securely over the weld area, providing a permanent, leak-proof seal that ensures the long-term reliability of your HDPE infrastructure even in demanding environments.
