Product Description

Product Description

The Rubber Inflatable Pipe Plug with Good Burst Strength, Elasticity & Flexibility

    Rubber inflatable pipe plugs 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

    The main body of the plug is typically made from oil-resistant and aging-resistant synthetic rubber, with common materials including Nitrile Rubber (NBR), Chloroprene Rubber (CR), and EPDM. To enhance pressure-bearing capacity and prevent over-expansion or deformation, a high-strength fabric or cord reinforcement is usually embedded inside as a skeleton.

Function

*Pipeline Blockage: Forms an airtight seal inside the pipe to effectively stop the flow of water, gas, or other media-3-10.
*Pressure Testing: Provides a closed environment for pipeline systems to facilitate leak detection and pressure testing-10.
*Temporary Isolation: Safely isolates specific pipeline sections during repair, renovation, or new construction to ensure work safety.
*Fall Protection: When used in vertical pipes or openings, it prevents the accidental dropping of tools or debris-1.

Usage

*Pipeline Blockage & Water Stoppage: Used for temporary water stoppage during pipeline repair or renovation-4.
*Air Tightness & Pressure Testing: Provides a reliable isolated test unit for newly built or rehabilitated pipeline systems-10.
*Construction Safety Protection: Serves as a safety cap for pipe openings during construction to prevent personnel or object falls-1.
*Pipeline Cleaning Isolation: Isolates target pipeline sections during high-pressure water or chemical cleaning.

Specification

*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

Installation

Product Details

Applications

*Pipeline maintenance. During pipeline repairs or replacements, the rubber inflatable pipe plug can be used for temporary sealing to prevent sewage or pollutants from entering the pipeline.
*Pipeline inspection. During pipeline internal inspection, rubber inflatable pipe plugs can be used to isolate the inspection area, ensuring a clean inspection environment.
*Drainage system maintenance. In urban drainage system maintenance, rubber inflatable pipe plugs can be used to block drainage pipelines for water-tight testing or cleaning operations.
*Industrial pipeline cleaning. In the process of industrial pipeline cleaning, rubber inflatable pipe plugs can be used to isolate the cleaning area, preventing leakage of cleaning fluids.
*Construction. In construction, rubber inflatable pipe plugs can be used for temporary sealing of pipelines to prevent contamination and damage during the construction process.
