Line stopping is an important technique in pipeline maintenance that allows you to repair or modify a pipeline without shutting it down. There are two primary types: inflatable and mechanical line stops.
It works by temporarily closing off a segment of the pipeline, allowing professionals to safely complete critical tasks without disturbing operations. There are two major types of line stopping: inflatable and mechanical.
In this article, we'll go over the key differences between...
Bypass plugs are commonly used for monitoring, testing, and repairing pipelines in waterworks, sewer and plumbing systems, oil and gas infrastructure, chemical industries, and more. They are designed to isolate a section of the pipeline temporarily while still allowing the fluid or gas to flow through. The primary advantage to using a bypass plug for pipeline testing, maintenance, or repair is that you don’t have to shut down the system or completely stop the flow during the project. ...
Sewer lines frequently experience significant issues, such as clogs, leaks, and degradation, which can result in costly repairs and inconveniences. Traditional repair methods usually require digging up and replacing damaged pipes, which may be costly and time-consuming.
Sewer pipe lining is a modern, efficient option for sewer repair. This method involves installing a new lining into existing pipes to successfully restore their functionality without the need for major excavation...
Maintaining clear and efficient water pipes is essential in commercial settings, where high water demand and complex systems can cause problems if not properly maintained. Blockages, air pockets, and sediment buildup can create major problems, ranging from low water pressure to complete system failure. This is where pipe purging comes in.
Why Pipe Purging is Essential for Commercial and Industrial Water Systems?
Pipe purging is...
Cleaning pipelines is critical to make sure industrial processes run smoothly and safely. Pipelines may accumulate debris over time, reducing flow efficiency, increasing downtime, and posing possible safety risks.
Regular pipeline cleaning ensures optimal performance, prevents clogs, and extends the pipeline's lifespan. Neglecting this maintenance can lead to costly disruptions and major safety hazards, therefore routine pipeline cleaning is necessary for smooth industrial...
Early detection of plumbing leaks is essential to avoid expensive repairs and significant water damage. Traditionally, plumbers have used various methods to identify leaks, including visual inspections, pressure tests, and even listening devices. These techniques, while effective to some extent, can sometimes miss small or hidden leaks that could cause problems later.
Enhancing...
Efficient drainage systems are crucial for smooth industrial & commercial operations. When drain lines get clogged, they can slow down productivity, create safety risks, and increase operational costs. A clogged drain line can lead to serious problems in any industrial facility from halting production lines to creating unsafe working conditions, the consequences can be costly and disruptive.

Hot tapping is a method of connecting to a pipeline without depressurizing or removing it from service to make repairs, conduct maintenance, or add a new section of pipe. Hot tapping can be dangerous if not handled the correct way, and it’s very important to understand the conditions of the line, before you begin the process.
The basics of hot tapping
To perform a line stop, line intervention or line isolation via hot tapping, first install a fitting (nozzle, nozzle...
Problem:
Lametti & Sons, Inc. has been rehabilitating pipelines and sewers since 1953, and they are CIPP experts. But that doesn’t mean every project is completed without a hitch. “Very cold soil on a 14,000 foot interceptor rehabilitation in southwest Minneapolis caused a ‘soft spot’ near the middle of a run,” explains Project Manager Ross Larson. “It only happens a dozen or so times a year, but when it does, we’re in danger of losing...

A U.S. based facility needed contingency equipment added to an existing chill water system, requiring the addition of block valves to be added in new chillers and generators. The chill water system operates at 30 PSI and 45° F, with managed flow of service through 14” and 16” carbon steel pipe...
Out of the 93% of Americans that planned to spring clean in 2022, 92% said they were considering taking action to reduce their environmental impact while doing so, according to a Bona and Harris Poll survey of over 2,000 U.S. adults. Furthermore, more than half 56% said they were considering the use of cleaning products that...
Mechanical pipe plugs are essential devices for pipeline maintenance. They temporarily seal or isolate sections of pipelines making the flow more accurate and controlled. Additionally, they are referred to as mechanical pipe stoppers, pipe bungs, pipe test plugs, and line stops as well...
When it comes to stopping flow in a pipeline, there are several different pipe plug options available to you. Which one you choose will depend on a variety of factors, including the type of substance you’re blocking, how much pressure there is, how you’re accessing the inside of the pipeline, how long you’re blocking the pipeline, and your purpose for stopping flow in the first place.
In this article, we’re discussing which type of pipe plug is best for different...
Use Petersen Products Inflatable Pipe Plugs
Figuring out the best approach to solve a problem in a pipe system can be challenging, especially if you aren’t familiar with the system. Each one has a history, and the conditions can vary dramatically from one pipe system to the next. For that reason, pressure testing is vital to ensure that the pipes are capable of withstanding certain levels of pressure.
If your work involves industrial and commercial applications, you’re...
The advantages of inflatable pipe plugs
When handling a line stop operation, you have two primary pipe plug variations to choose from: inflatable and mechanical. Both types can be effective at getting a workable seal, but there are certain conditions and situations when it makes the most sense to use an inflatable plug. In this article, we’ll cover what inflatable plugs are and when it makes the most sense to use them.
