Metalsin’s Ductile Iron Straight Pipe Repair Clamps for plastic piping provide a versatile and robust solution for the maintenance and emergency repair of water supply, drainage, and sewage systems. These repair clamps are specifically engineered for straight pipe sections and are fully compatible with a wide range of plastic materials, including PE, HDPE, PVC, uPVC, and PPR. Understanding that field conditions vary, we offer customizable lengths for every nominal/ standard pipe size to meet specific project requirements, ensuring a precise and secure fit for every application.

The construction of Metalsin‘s straight pipe repair clamps for plastic systems features a high-strength, two-piece ductile iron body, a pair of high-performance sealing gaskets (EPDM or NBR), and a complete bolting set (bolts, nuts, and washers). An optional configuration is the integrated vent plug, which allows for air discharge and pressure relief during installation to ensure a perfect seal against the pipe surface. Detailed material grades for each component are outlined in the technical table below.
