Q: What are inflatable pipe plugs used for?

Inflatable pipe plugs are used to block, test, isolate, or control flow inside pipelines and sewer systems. Commonly used during pipeline maintenance, construction, repair, inspection, and pressure testing. Once inserted into a pipe and inflated with air or inert gas, the plug expands to create a secure seal inside the pipe. These plugs are widely used in municipal sewer systems, industrial pipelines, commercial plumbing, and large diameter pipe applications

Q: How do inflatable pipe plugs work?

Inflatable pipe plugs work by expanding inside a pipe to create a temporary seal. The plug is inserted into the pipeline in its deflated state and then inflated using air or inert gas. As the plug expands, it presses against the inside pipe wall to block flow or isolate a section of pipe. Depending on the model, plugs may be used for blocking, bypass flow, smoke testing, or pressure testing applications.

Q: What is the difference between blocking pipe plugs and bypass pipe plugs?

Blocking plugs are designed to isolate a pipe section by completely sealing the line. Bypass pipe plugs include a rigid center tube that allows air, water, or testing equipment to pass through the plug while the pipe remains sealed. Bypass models are commonly used for sewer testing, flow-through operations, and pressure testing applications.

Q: Are inflatable pipe plugs available for chemical or corrosive environments?

Certain pipe plug models are manufactured using chloroprene compounds designed to resist chemicals, corrosion, and harsh industrial conditions. These materials are often used in facilities where standard rubber compounds may degrade due to chemical exposure or aggressive operating environments

Q: What makes SAVA inflatable pipe plugs different?

SAVA pipe plugs are reinforced with Kevlar for added durability and are manufactured using specialized rubber compounds designed for toughness and flexibility. Their compact deflated size allows for easier installation through manholes, bends, and restricted access points. Models are available for commercial, municipal, high-pressure, and large diameter pipe systems, including options with bypass capability for testing and flow-through applications.

Q: How do I choose the correct Pipe?

Choose pipe by pipe inside diameter, pipe material, available insertion length, required backpressure, whether bypass flow is needed, and the condition of the pipe interior.

Q: What should be checked before installing Pipe?

Confirm the actual pipe inside diameter, clean the contact area, inspect the plug and hardware, verify inflation or mechanical expansion limits, restrain the plug against movement, and keep personnel out of the potential ejection zone.
