Inflatable Pipe Stoppers

Inflatable Pipe Stoppers
When water needs to be blocked in pipes or sewers, inflatable pipe stoppers are an efficient solution. By inserting an inflatable pipe stopper, the water supply is shut off. This allows maintenance personnel and specialists from various industrial sectors to solve a problem or carry out maintenance safely.
Inflatable pipe stoppers ensure a perfect seal and have high back-pressure resistance.
Our inflatable pipe stoppers are made from high-quality rubber and reinforced with a synthetic mesh, which significantly increases the product’s reliability.

Are you working on a construction project that requires inflatable pipe stoppers? It’s important to know that inflatable pipe plugs come in all kinds of shapes and sizes. That’s why it’s crucial to do proper research and purchase the right plugs that perfectly fit your unique project and needs. But don’t worry! LDA provides you with an overview of the various inflatable pipe plugs, pipe stoppers and pipe closures that can be used for fire water containment — all of them designed for the installation, repair and maintenance of the water supply network.

Diaphragms
Working on an offshore construction project? Then you might consider using diaphragms. Diaphragms are adjustable round rubber seals. They are mounted or welded into the legs of offshore platforms to increase the buoyancy of the platforms. In addition, these inflatable pipe plugs help the platform maintain its center of gravity while floating at sea.

How Can I Temporarily Seal My Sewer?

Discharge Pipe and Pipe Stopper – OPL Series
The OPL stoppers are used for the temporary sealing of pipes with diameters from 30 to 2000 mm.
These plugs are deployed during the construction or maintenance of pipe networks, or for hydraulic pressure tests, pipe isolation or temporary fillings.
Each plug has its own expansion range to cover different pipe diameters. It can withstand a water column height of up to 30 bar or more depending on the application. Some models are equipped with a continuous bypass that allows back-pressure to be released before removing the plug.
The plugs are made of coated textile with an elastomer on both sides and subsequently vulcanized in a hot autoclave. This construction guarantees the product’s reliability and robustness against wear, chemicals, oil and seawater.

Accessories

• 10 m compressed air hose, ¼”G connection with 0 to 6 bar manometer, a ¼-turn tap and couplings to connect to a compressor or manual pump.
• Semi-rigid connection between mini-bellows and the coupling for hard-to-reach areas.
• Double bypass, for air testing only.

How Can I Seal My Sewers or Pipes?

At LDA you can buy pipe stoppers both large and small.

OHP/OPV – High-Pressure Stoppers
OHP/OPV high-pressure stoppers are excellent for sealing different types of pipelines. These inflatable pipe stoppers are ideal for projects with pipes made of concrete, steel or stainless steel. Moreover, these stoppers are designed to withstand low, medium and high pressures up to 35 bar. This makes them perfect for projects where extremely high pressure plays a role, such as nuclear, offshore, onshore and gas projects.

THPGV Inflatable Stoppers
If you are working on a project at or near a nuclear facility, THPGV inflatable stoppers are an excellent tool. These inflatable plugs are specially designed to close off steam generator sewers and to purge these electronic devices of foreign liquids during maintenance work. The THPGV inflatable stopper is also particularly useful in unique situations such as freezing or bursting pipes, where it is crucial to quickly shut off a device.

Uniplug Pipe Stoppers
Uniplug pipe stoppers are an extremely useful tool. These are low-pressure stoppers that are particularly handy at nuclear sites. Uniplug pipe stoppers can prevent foreign objects from entering a pipeline. Moreover, these stoppers have been tested to comply with the foreign material exclusion standard.

OTR – For Inspection and Testing
OTR pipe stoppers are very useful test plugs for inspecting your wells. You should use the OTR stoppers if you are working on a project related to wastewater system management. OTR pipe stoppers are extremely easy to install and make it easy to test the density of a wastewater system. In addition, these inflatable pipe stoppers are adjustable and lightweight, making them easy to transport.

Stoppers for Oval Pipelines
Other useful test plugs are pipe stoppers for oval pipelines. These inflatable pipe stoppers are particularly handy for projects with oval pipelines. As test plugs, oval inflatable pipe stoppers are excellent for both water and air testing. In addition, this specific type of pipe stopper can also be welded into bypass pipes. Oval inflatable plugs can be used as test plugs on bypass pipes that allow air, gas and other fluids to pass through during maintenance.

OFR – Anti-Pollution Stoppers
Are you environmentally conscious? There are inflatable plugs such as the OFR Anti-Pollution Stoppers that are specially designed with the environment in mind. The OFR Anti-Pollution Stoppers are particularly useful in cases of accidental environmental damage. The plugs have an extremely fast response time thanks to their ability to be inflated remotely.
The OFR Anti-Pollution Stoppers are designed to inflate and act as valves in the event of accidental environmental damage. By acting as valves, these inflatable plugs can divert contamination, for example, into a catchment basin. In this way, the OFR Anti-Pollution Stoppers can function as a purification monitor.
