Product Description

Product Description

The with Good Burst Strength, Elasticity & Flexibility

    are a type of internal intercepting flow device made from high-quality rubber, featuring excellent burst strength, elasticity, and flexibility. They are primarily used for intercepting flow in drainage pipelines and are widely applied in the fields of water supply and drainage, civil engineering, and fire rescue. This inflatable bag expands through air injection, causing its wall to closely adhere to the inner wall of the pipeline, thereby achieving the purpose of sealing the pipeline.

Material

 * Airbag Body: The main body is composed of high-strength synthetic rubber (e.g., chloroprene, nitrile rubber) laminated with multiple layers of high-strength fabric (e.g., polyester fiber, nylon cord).
 * Skeleton Reinforcement: The embedded fabric skeleton significantly enhances the airbag's tensile strength and pressure resistance, preventing over-expansion or rupture under high pressure.
 * Fittings: Equipped with specialized air valves made of metal or high-strength engineering plastic for reliable inflation/deflation. Connectors are typically galvanized or stainless steel to resist corrosion in damp environments.

Function

 * Rapid Blocking: Inflates quickly to expand and tightly conform to the pipe wall, effectively blocking water, air, or slurry flow relying on friction and expansion pressure.
 * Creating Dry Workspace: Provides a dry, water-free working space for repair procedures inside the pipe, such as inspection, cleaning, resin spraying, or liner installation.
 * Assisting Pressure Testing: Used for pipeline water tightness (closure) tests and air pressure tests, helping to detect pipeline seal integrity and locate leaks.
 * Safety Assurance: Prevents incoming water or debris from flowing into the work area during pipeline repair or construction, ensuring worker safety.

Usage

 * Trenchless Rehabilitation Construction: Blocking both ends of a pipeline section before executing trenchless repair processes like UV curing, spiral winding, or lining methods, to create necessary working conditions.
 * Pipeline Inspection & Testing: Used for sectional water/air tightness tests to assess pipeline integrity and sealing.
 * Maintenance & Renovation Isolation: Isolating construction areas when replacing pipe sections, adding branches, or valves, enabling construction without flow interruption or minimizing water shutdown impact.
 * Pipeline Cleaning Isolation: Used to isolate target sections during high-pressure water jet or chemical cleaning.

Specifications (Customizable)

*Material: Natural rubber, synthetic rubber materials (such as nitrile rubber, neoprene, etc.).
*Pressure rating: 0.1–1.0 MPa.
*Diameter range: The rubber inflatable pipe plug has a wide range of diameters, from a few centimeters to several tens of centimeters, to accommodate different sizes of pipelines.
*Length: The length of the rubber inflatable pipe plug varies according to the pipeline length and sealing requirements.
*Inflatable equipment: Air pump or blower
