Axially Restrained Repair Clamp for Plastic Piping

December 27, 2025

Product Overview

Metalsin’s axially restrained repair clamp for plastic piping is the definitive solution for repairing HDPE, PVC, uPVC, and PPR pipelines in areas vulnerable to axial movement or joint displacement. This specialized repair clamp is engineered specifically for pipe joints and sections where high pressure or ground shifts might cause conventional straight pipe repair clamps to slip. By combining superior leak-sealing capabilities with a robust mechanical anchoring system, Metalsin ensures that your pipeline repairs remain secure and permanent, even under the most demanding operational conditions.

The ductile iron axially restrained repair clamp for plastic piping.

The technical advantage of this axially restrained repair clamp lies in its innovative body design, which features integrated, evenly distributed gripping lugs at both ends. As the clamp is tightened to achieve a high-pressure seal, these lugs engage the pipe surface to create a localized mechanical lock. This “positive engagement” prevents the clamp from shifting or pulling out due to internal hydraulic surges, thermal expansion, or external vibrations.
