Description & features

The Plugline Cone Pipe Stopper is a versatile and durable solution engineered for the temporary or permanent sealing of pipelines with irregular or standard geometries. Its unique conical design allows it to provide a secure, leak-proof fit in a wide range of pipe diameters and shapes—including egg-shaped, rectangular, and other non-circular profiles. This adaptability makes it an indispensable tool for complex sewage systems, industrial pipelines, and large-scale construction projects.

Key Features

  • Universal Conical Shape: The tapered design ensures a tight seal across diverse pipe diameters, ranging from 150 mm to 2200 mm, and adapts easily to varying pipe cross-sections.
  • Reinforced rubber construction: size range DN50 — DN1500, working pressure 1 bar, back pressure 0,5 bar, operating temperature −40 to 70 °C, Quick Coupling / Schrader air connection.
  • Irregular Profile Compatibility: Specifically engineered to seal egg-shaped, rectangular, and U-shaped channels where standard cylindrical plugs often fail.
  • Robust Reinforced Construction: Crafted from high-strength reinforced rubber and corrosion-resistant metal components to withstand high back-pressures.
  • Superior Chemical Resistance: Built to perform reliably in pipelines handling aggressive fluids, sewage, and industrial chemicals.
  • Ergonomic Handling: Equipped with integrated handles for precise placement and efficient removal, even in confined or challenging environments.

Advantages

  • Unmatched Versatility: A single cone stopper can service multiple pipe sizes and shapes, providing an all-in-one solution for diverse infrastructure needs.
  • Cost-Efficient & Reusable: The heavy-duty construction ensures long-term durability and repeated use, significantly reducing equipment lifecycle costs.
  • Maximum Operational Safety: Effectively prevents leakage and environmental contamination during critical maintenance, repair, or bypass operations.
  • Rapid Deployment: The lightweight, intuitive design allows for quick insertion and inflation, minimizing project downtime and labor requirements.
  • Customizable Solutions: Available in various sizes and specialized configurations to meet the unique demands of specific engineering projects.

Application Areas

  • Sewage & Drainage Systems: Ideal for isolating and testing standard circular pipes as well as older, egg-shaped municipal sewer lines.
  • Hydrostatic Pressure Testing: Sealing one or both ends of a pipe section to test for leaks under pressure.
  • Complex Construction Projects: Used to block or pressure-test water, gas, and wastewater lines during installation or rehabilitation.
  • Stormwater Management: Effective for sealing rectangular culverts and irregular drainage channels during maintenance or flood control.
  • Emergency Response: Reliable for the rapid isolation of damaged pipelines to control spills and protect surrounding environments.

Plugline Cone Pipe Stoppers offer the ultimate in sealing flexibility, providing a professional-grade solution for the most challenging pipe profiles and high-pressure environments.

Recommended deployment procedure

Plugline Inflatable Pipe Stoppers are used for sealing, blocking and pressure testing pipework. Follow the procedure below for safe installation and removal.

01
Inspect

Verify each stopper for surface defects. Confirm reference matches purchase order. Pre-test in a clean environment to nominal 0.5 bar.

02
Position

Insert deflated. Place at least two pipe-diameters inside the bore. Secure the connector hose to the inflation valve.

03
Inflate

Inflate to nominal pressure indicated on the datasheet. Hold for 60 seconds and verify seal under audible test.

04
Test

Perform line test per EN 1610 or local code. Record drop, hold time, ambient temperature.

05
Recover

Deflate fully before withdrawal. Inspect for damage. Stopper may be reused for up to 200 cycles under nominal conditions.
