Live pipeline maintenance requires crews to balance uninterrupted flow with safety and operational control. Shutting down pipelines can cause service disruptions, regulatory scrutiny, and significant downstream costs, while working on active pipelines introduces risks related to internal pressure, residual product, and limited margins for error during intervention. #pipelinemaintenance #pipelineisolation

One of the best solutions for blocking off pipelines is by using a type of inflatable bag called grout bags. Let’s take a look at how the process of sealing a pipeline to be decommissioned and abandoned works.

Consult a Petersen professional to determine the best hot tap plugging solution for your project.

Inflatable bladders can be deployed along coastlines or near inlets to act as floating barriers that block and redirect sargassum seaweed before it reaches the shore. By guiding the seaweed into collection zones, these bladders make removal easier and help protect beaches, seawater intakes, and marine habitats.

128-Series Insertion System Kits are used for installing and inflating pipeline plugs or other devices within pipes. Get all necessary tools with PeteStop® Line Stop Insertion System by Petersen Products.

Completion plugs seal off pressurized pipelines after valve removal, allowing permanent closure with a blind flange. Compatible with most pressure, size, and chemical requirements, they eliminate the need to reinstall valves and support safe pipeline burial.

Compare rubber drain bladders and fabric flushers like the DrainJet® across key factors such as durability, flexibility, safety, hot water use, and professional choice. This side-by-side view makes it easy to select the right tool for effective drain cleaning.

Discover the durable and flexible 113-Series Multi-Flex® High Expansion Pipe Plugs by Petersen Products. Ideal for low-pressure gas systems, pipeline testing, and industrial maintenance, these plugs offer chemical resistance, compact storage, and reliable sealing for various pipe shapes and sizes.

Rigid Core Bore Hole Plugs by Petersen Products improves pipeline safety, minimize environmental risks. hey feature durable polyurethane inflatable seals, support high-pressure applications, and enable easy pipeline pressurization or monitoring with a central bypass.

Hydrocarbon-Resistant Multi-Flex Pipe Plugs – 114 & 115 Series These compact, high-expansion plugs seal irregular or out-of-round pipes in oil, gas, and industrial systems. Made with hydrocarbon-resistant nitrile, the 114 Series offers strong sealing and durability, while the 115 Series includes block and bleed capability for added safety.

High Pressure Test Plugs use the test pressure to help seal more securely against the pipe's inner diameter. Typical Applications: Force and water main, lift stations, nuclear cooling lines, fire protection lines, special plant situations, irrigation supply lines, and many other projects.

High-pressure block and bleed 127BB pipe plugs available in various specifications to fit different pipeline diameters

Pipeline Cleaning Balls are an affordable tool for cleaning new pipelines prior to line acceptance testing. They are also used for cleaning grease and debris from existing lines.
