Multi Size Metal Core Pipe Test Plugs (1,5 bar)

Description & features

Plugline Multi-Size Metal Core Pipe Test Plugs are heavy-duty solutions engineered for high-pressure sealing and precision flow management. These plugs are built around a robust metal core that provides unmatched structural stability during rigorous testing. Designed for maximum versatility, they are available in single or multi-bypass configurations, allowing for simultaneous flow-through, air monitoring, or water feeding during pipeline maintenance and validation.

Key Features

• Reinforced Metal Core: The high-strength metal center ensures the plug remains stable and secure under extreme back-pressure, preventing deformation in large-diameter lines.
• Steel construction: size range DN100 — DN1200, working pressure 1,5 bar, back pressure 0,5 bar, operating temperature −40 to 70 °C, Quick Coupling / Schrader air connection.
• Single & Multi-Bypass Options: Available with single or double bypass ports to facilitate complex testing procedures, such as concurrent water filling and air venting.
• Multi-Size Versatility: A single plug covers a broad range of pipe diameters, making it an adaptable and cost-effective tool for varying project requirements.
• Precision Flow-Through Design: Allows for controlled liquid or gas bypass, ensuring that essential system functions can continue while sections are isolated.
• High-Friction Inflatable Seal: The durable outer sleeve expands to create an airtight and watertight grip against the pipe wall, regardless of the pipe material.

Advantages

• Advanced Testing Capability: The multi-bypass configuration is ideal for professional air and water pressure testing, providing dedicated ports for gauges and test media.
• Structural Integrity: The metal core design offers a higher safety factor in industrial environments where high-pressure tolerance is a non-negotiable requirement.
• Operational Continuity: By utilizing the bypass ports, operators can manage bypass pumping or drainage without a total system shutdown.
• Long-Term Durability: Constructed with premium, corrosion-resistant materials to ensure reliable performance over hundreds of inflation cycles.
• Simplified Logistics: The multi-size range reduces the inventory needed on-site, simplifying transport and preparation for field technicians.

Application Areas

• Municipal Sewer & Water Mains: The primary choice for sealing and testing large-scale city infrastructure where bypass flow is required.
• Complex Pressure Testing: Specifically designed for scenarios requiring double bypass ports to feed water and monitor air pressure simultaneously.
• Hydrostatic Pressure Testing: Sealing one or both ends of a pipe section to test for leaks under pressure.
• Wastewater Treatment Plants: Used for isolating sections of active lines during upgrades or emergency repairs without halting flow.
• High-Pressure Leak Detection: Provides a stable platform for identifying leaks in newly installed or rehabilitated industrial pipelines.

Plugline Multi-Size Metal Core Pipe Test Plugs offer the strength of a metal core combined with the functional flexibility of single and multi-bypass ports, delivering a professional-grade solution for the most demanding pipeline environments.
