High-Pressure Isolation Plugs

High-pressure isolation plugs are specialized devices designed to create a secure seal and isolate sections of piping or equipment subjected to high pressure.
High pressure isolation plugs are used to prevent or restrict the flow of fluids or gases during testing, or to isolate sections of piping.

High-pressure isolation plugs, also known as pressure test plugs or pipe isolation plugs, are devices used to seal and isolate sections of pipe lines under high pressure. 

The versatility and reliability of high-pressure isolation plugs make them indispensable tools in ensuring safety and operational integrity in high-pressure systems.They are used in various industries to ensure safe and efficient maintenance, repairs, and testing procedures.

Uses for High-pressure Isolation Plugs

  • Stormwater pipes
  • Irrigation systems
  • Residential plumbing
  • Municipal testing of new and repaired pipelines
  • Blocking water/sewage flows during maintenance, modifications, and repair
  • Restricting, diverting, and bypassing flow in pipes during modifications, maintenance or testing

The range of multi-size inflatable high-pressure pipe plugs is suited to pipes from 250 mm to 1800 mm diameter and withstand back pressure of up to 12m.

Kevlar reinforced

All the inflatable multi-sized plugs have a superior plug surface pattern for blocking pipes with higher pressures. Using a Kevlar reinforced rubber compound, they exhibit suitable length, low weight, and excellent sealing ability.

They are all fitted with non-corrosive components and are guaranteed safe when working within their recommended range. 

Multi-size high-pressure isolation plugs are stretchable; therefore, only a few models are required to cover pipelines of different diameters.

High-pressure bypass plugs

These inflatable plugs allow fluid to flow through once inserted. Bypass plugs can be installed when the pipe’s back pressure exists and sealed once the plug is locked in place.

Frequently Asked Questions

Giant Inflatables Industrial engineers its Kevlar-reinforced plugs to handle very high back pressures, far exceeding the capabilities of standard rubber plugs. Each plug is custom-designed and tested to meet the specific pressure requirements of the client's application.
A single multi-size plug is designed to effectively isolate a range of different pipe diameters. This versatility allows companies to reduce their on-hand inventory and associated costs while maintaining the capability to service a wide variety of pipelines.
Each high-pressure plug is a custom-engineered safety device. Giant Inflatables Industrial provides project-specific documentation and procedures to ensure safe and effective installation, operation, and removal.
Giant Inflatables Industrial fabricates its plugs from a range of high-quality materials, including nitrile, neoprene, and natural rubber. The material for each plug is selected based on its durability and resistance to the specific petrochemicals or abrasive contents of the pipeline.
High-pressure bypass plugs are engineered with a hollow center. This feature allows fluids or gases to pass through the plug in a controlled manner, which is essential for conducting pressure tests or temporarily redirecting flow during maintenance.
Giant Inflatables Industrial ensures all its products meet stringent industrial standards and adhere to the highest engineering principles. Each high-pressure plug undergoes rigorous quality control and testing before delivery to certify its performance and reliability.
The materials for each plug are selected based on the specified working environment. The custom fabrication process includes selecting materials that will maintain their integrity and flexibility in the client's required operational temperatures, including sub-zero conditions.
