How Our Testing System For Pipelines Works

What We Can Do For You

One pipeline leak can cause over 35 gallons of soil damage. Unfortunately, the system used to test most pipelines does next to nothing to help you evaluate how your pipelines are performing and where to spend your maintenance dollars  next. Because of the expense of hydrostatic testing most owners only do hydrostatic testing every five years.  Infrequent  testing leaves the pipeline owner with the risk that an ongoing release over several years and hundreds of gallons of product may have left the containment which by delaying testing has become a catastrophic leak.

The PHDleak™ pipeline testing system we have developed is a major improvement in several crucial ways. Our system allows us to test pipelines faster, cheaper and more accurately. Most importantly, we can give you crucial information regarding how your pipeline is working, so you can maintain the asset more efficiently.

So, how does our system work?

If you are ready to switch to a more efficient and effective testing system, we need to lay the foundation for years of successful testing. First, we perform a PHDleak™ volumetric test to determine the pipeline sections MDL for the test section. This initial test will take four hours, but once a section has been tested, future testing will only take two hour.

One year after the initial test is performed, we will conduct a second test to see if the pipeline has changed. After only one year, we will be able to better predict the viability of each section of the pipeline. So after the first years testing, we will able to use the data collected in the following ways:

  • Testing: First we open the valves to the pipeline and set it to the right pressure. Next, we close the vales so we can start the test. Ten minutes later we open the valves back up, reset the pressure and move to the next section. This quick and simple test will give us a leak rate for that section of pipe.
  • Predicting: Before we even get on site, we can predict how the pipeline should behave, based on and tests from previous years.
  • Evaluating: Comparing our predictions with the current test and previous tests, we get a nuanced look at how individual sections of the pipeline are working. If something is wrong, we look for possible explanations. And if there are no explanations, we know there is a leak.

Since our process is not as invasive or time-intensive as dead-weight testing, we can gather information more often. The cost to send two men out to test a pipeline is only $350 an hour, including equipment plus mobalization. The units we use to test the pipeline are self-contained, battery operated and very stable. All this means we can give you reliable cost estimates, so you can plan for the basic testing you need.

You do not have to live with the flaws of the dead weight testing process any longer. Our system is less expensive, less time-consuming and more detailed. We will provide you with yearly testing and weekly fly-overs, so you can properly monitor your pipelines all year round, not just once every five years.
