Live repairs to In-service pipelines

Mechanical damage and corrosion is part of every mechanical process and sooner than later, there will be a time when the mechanical system will develop faults and require repair. It must be noted that stopping operations and getting everything back online take time and often culminates in lost time and effort, something not too desirable for time-critical industries such as gas and oil, hence the process of Pipeline Tapping.

Pipeline Tapping is relevant for jobs where the work cannot be halted at all. The risks of opening up pipelines when they are under steam and live are several. In worst cases, it can lead to the air being contaminated with poisonous greenhouse gases. To minimize the risk and keep risk of seepage under control, Pipeline Tapping is the most reliable solution. With the help of this technique costly shutdowns can be averted.

5 Fundamentals to Note about Pipeline Tapping

• Pipeline Tapping should not be considered for routine maintenance.  There are other faster and economically viable alternatives that should be considered before Pipeline Tapping. 

• The task is very technical and requires the expertise of the right people for the job to go through without any untoward happening in site, and most importantly to get operations back online in as short a time as possible.  Hire a talented crew for the job. 

• Concerns of health issues arising from Pipeline Tapping and effect on the metallurgical resources must be addressed by getting a proper plan approved ahead of time to mitigate accidents and unplanned delays.

• Pressure of the ingredients within the pipe must be contained with of adequate thickness or risk leakages. Which means new section that is to be added to the repaired pipeline must be of the same thickness as the one replaced. 

• Proper replacement is of critical importance in Hot Tapping Pipelines. Using anything less than anything approved for the job will invite mishaps.

Pipe Tapping – The Secret behind Maintenance Work Carried Out On Live Pipelines

Imagine the mess a leaking sewage pipeline will create if it is left unattended for weeks at end! In thickly packed urban areas in the UK where sewage lines from every single household converges into one large sewage pipeline, maintenance workers cannot risk such disasters to happen. Preemptive measures are taken in order to mitigate disaster situations. You might have seen maintenance workers going working on pipelines and wondered what actually went on behind the scenes. Well, here is a glimpse into what happens when maintenance workers carry out what they call Pipeline Tapping.

Putting a cork on the pressure

Actually, the very first thing that happens in pipeline tapping is cutting a hole through the hard shell of the pipeline. This allows for tools to be inserted through the hole that helps in controlling the pressure within. What this does it makes it quite possible to manipulate the pressure acting along the pipeline, letting workers plan out their work better without causing any disruptions.

One continuous process

Everything in pipeline tapping is one single process that begins with the pilot bit cutting through the pipe shell and ends with the removal of the coupon (section of the pipe that is cut and removed). When the cutter has done its job, subsequent phases of the process is carried out. Adding new pipelines or removing a redundant section can be easily done with pipe tapping. So effective are the methods of Pipeline Isolation that it can be safely and effectively used for pipes that are on the surface as well as those that are under water.

Pipe freezing – the magic of liquid nitrogen

Freezing pipe or pipe freezing is a much-used pipeline service technique, wherein the content of the pipeline system is freezed with the help of liquid nitrogen. This leads to the formation of the ice plugs, which then allow the maintenance work, without incurring the costs and down time of a complete system drain out.

The procedure is non-intrusive in nature, and involves isolating a short section of the affected pipeline. However, the procedure can be performed by only skilled men. Here are the major advantages of freezing pipe procedure:

• No need for drainage, venting or refilling
• Pipe freezing can be applied on all the popular pipe materials and pipes containing a wide range of liquids
• Environmentally friendly solution
• Safe and cost effective

.
Under the procedure, the skilled men cover the pipeline with a jacket, and then liquid nitrogen is introduced into the jacket so as to freeze the content of the pipeline. Liquid nitrogen has a temperature of - 196°C, which quite effectively solidifies the content, and let the workmen complete their work.

As of now, there are many companies that provide freezing pipe and other pipeline maintenance services at affordable charges. With Google search, you can find out a lot about these companies, and land on their websites to get to know more about their offerings, and which one would make more sense to your specific business requirements.

Line Stopping – A great way to avoid the complete shutdown

Have you ever worked on a live pipeline active under high pressure? If yes, you can easily determine the working conditions under such situations. Workings on live pipelines possess heavy danger to the lives of people and it is important to take necessary precaution at the maximum. However, with the advancements in technologies have resulted in greater security and safety and one such technique is line stopping which can be defined as a mechanical way of creating a temporary isolation in a live pipe. This is done of pipelines where some flow exists and there is no possibility of complete freezing, or a total shutdown is out of scope.

The best thing about this process is that an engineer can perform various kind of work on the pipeline while not disturbing its flow which also avoids the chances of complete shutdown. It can be done on most common pipeline materials such as Steel, Cast Iron, Ductile Iron, Copper, Stainless steels, Plastics and Cement Asbestos.

A customized fitting is either welded or bolted to the live pipeline using valves. Under pressure drilling is done whenever required to install the line stopping equipment. In case a bypass is required, it is installed during the initial set up which ensures uninterrupted flow in the main line.

Hot Tapping Pipelines – An Integral part of industry

Particularly in chemicals and gas industry, pipelines play a very great role in maintaining the efficiency of operations. Therefore, it becomes important for plant workers to ensure their working conditions remain normal throughout the operations. Any kind of mechanical failure can result into several losses. Any kind of maintenance work on pipelines sometimes hampers the work in great way by putting the lines idle. So, here comes the need for hot tapping pipelines that allow engineers to carry out various kinds of maintenance or repair work without the need for total shutdown of operations.

This technique is of great value as it doesn’t cause any kind of hindrance to existing work. In fact, it makes way for continuous operations as pressure is thoroughly contained. Engineers can carry out the job in any particular section of the active pipe without shutting down other sections. This process is limited only by the amount of pressure that has to be restricted.

The high level of flexibility makes it the most sought after process among companies as a way of working on pipelines. This process can be done both manually and automatically, and can be performed on both surface pipelines and sub area pipelines. Hot tapping is typically performed on materials such as carbon steel, stainless steel, cement lined pipe, fiberglass, or plastic pipes.
