If you have old or damaged subsurface pipes, you are not alone. Sewer and drainage systems around the country are reaching the end of their useful lifespans, resulting in leaks, clogs, and costly repairs.
Trenchless pipe lining addresses this by repairing pipes from the inside with a flexible sewage pipe liner—without the need to dig up streets or yards. This method is now widely used in the industry for its reduced surface disruption.
Trenchless pipe lining has grown more popular due to its less...
Pipeline tapping, commonly referred to as hot tapping, is the practice of creating new connections to an operational pressurized pipeline without disrupting flow. Hot tapping is a standard practice in industries such as water, gas, oil, and chemical processing as it allows system expansions, maintenance work and sensor installations without disrupting operations.
Selecting the appropriate equipment is vital for both safety and efficiency. Selecting appropriate hot tapping equipment helps prevent...
Two - 84” folding mechanical pipe plugs with Multi-Flex® annular seal for clearwell repairs
Charleston, South Carolina, USA
INTRODUCTION
Petersen’s solution allowed the Charleston Water System to isolate Clearwell 3 for 6 months.
PROBLEM
The Charleston Water System needed to shut down two 84" pipelines. The pipe plugs had to go through a small opening in a clearwell with an underwater isolation point located 100ft down, through a bend and 200ft across. Once the plugs were installed they would need...

Overview: Enhancing Safety in Hazardous Gas Pipeline Operations
In environments where toxic or flammable gases are present, such as natural gas distribution systems and industrial gas processing plants, ensuring safety during pipeline maintenance and modifications is paramount. The Double Block and Bleed (DBB) isolation method is a proven technique for safely isolating sections of pressurized pipelines, allowing for maintenance without compromising system integrity or safety.
Understanding the Double...
Overview: What Is Line Stopping?
Line stopping is a temporary method used to isolate a section of a pressurized pipeline so that maintenance or modifications can be performed without requiring a full system shutdown. It is a critical technique for ensuring safety, minimizing downtime, and maintaining operational continuity—especially in large-scale infrastructure systems.
The Challenge of Large Diameter Line Stops
Large diameter pipelines present unique challenges due to:
- High internal pressures...
Lifting and positioning large equipment requires careful planning and the appropriate equipment. Whether in construction, manufacturing, or emergency response, handling huge machinery and materials safely ensures that operations run smoothly and avoids costly delays.
Improper lifting can result in serious consequences. Equipment damage, occupational injuries, and unexpected repairs not only delay projects but also increase costs. Overloading lifting devices, using the improper tools, or neglecting...
Pipeline maintenance is essential for guaranteeing the efficiency and lifespan of pipelines. However, typical maintenance procedures usually require a complete system shutdown, which can result in costly downtime, service disruptions, and operational delays.
Temporary pipeline isolation is a practical solution for maintenance and emergency repairs. Instead of shutting down the entire system, only the affected section is isolated, allowing work to be done more efficiently. This approach is widely...
Sewer backup can happen when wastewater does not flow through a sewer line but backs up into the home. The damage can be severe; foul smells and health issues may become major concerns. When sewage enters a living space, it contaminates walls, floors as well as furniture which is then a total repair and sanitation measure. If things get really bad, a residential sewer backup could make a home impossible to live in for a while.
Clogged pipes, roots from trees, and heavy rain may all cause sewer backing...
Duct sealing is critical to increasing energy efficiency and HVAC performance. Leaky ducts cause air to escape, which makes heating and cooling systems work harder. This increases energy usage, resulting in higher utility bills.
Unsealed ducts also result in inconsistent airflow, making it difficult to maintain constant indoor temperatures. Poorly sealed ducting can attract dust, allergens, and contaminants, reducing indoor air quality. Over time, these issues can put a strain on HVAC components...
Pool Line Clogged? A clogged pool line drain can ruin an otherwise refreshing swim. When debris, scale buildup, or airlocks clog your pool's circulation, you may notice reduced water flow, gurgling noises, or air bubbles from the return jets. Left unchecked, these clogs can strain your pump and filtration system, resulting in costly repairs.
The good news? You do not have to call a plumber to fix it. With the correct tools and techniques, you can unclog your pool lines quickly and efficiently by...
Large-Scale Inflatable Plugs: The Innovative Solution for Permanent Sealing
Tunnels, mine shafts, canals, and similar structures often need to be sealed either permanently or for long term projects. The reasons for blocking can range from handling repairs, ending service, or preventing flooding. The problem is that effectively sealing off such large structures can be very difficult. But there is a solution. At Petersen, we have helped several customers complete projects and permanently block spaces...
Pipeline explosions can have catastrophic repercussions for both people and the environment, potentially causing fatalities, significant property damage and lasting environmental effects such as fires, chemical spills and air pollution. A pipeline explosion is capable of unleashing deadly power which could cause fatalities as well as lasting ecological issues such as fires.

Pipeline corrosion is the progressive degradation of materials due to moisture, chemicals, or electrochemical processes. This process weakens pipelines over time, leaving them prone to damage. Corrosion is a common problem for pipelines that convey water, oil, gas, or industrial materials since they are constantly exposed to harsh environments.
Pipeline corrosion prevention is critical for pipeline safety and efficiency. Corroded pipes may lead to costly leaks, environmental damage, and structural...
Pipe leaks are a common problem faced by homeowners and businesses alike, leading to water waste, increased utility bills, and potential damage to walls, floors, or foundations. When a pipe starts leaking, many people believe that replacing the entire pipe is the only answer. However, pipe leak repair is typically a faster and less expensive option. Instead of undergoing the inconvenience and expense of pipe replacement, sealing a leaking pipe with the proper equipment and methods can successfully...
