Sectional vs Complete System Hydrostatic Testing

Hydrostatic Pressure testing

Sectional vs Complete System Hydrostatic Testing

    Hydrostatic testing plays a vital role in ensuring the integrity and safety of pipelines, vessels, and other pressurized systems.

    This non-destructive testing method involves subjecting the system to a predetermined pressure, typically higher than the maximum operating pressure, using a liquid medium such as water.

    Importantly, Hydrostatic pressure testing can be performed either on individual sections or the complete system. Each approach offering distinct advantages and considerations. At Pipe Testing Services (PTS), we carry out hydrostatic and rising mains pressure testing services regularly for clients nationwide. If you’re looking for a cost-effective testing solution for water infrastructure and pipelines, don’t hesitate to get in touch.

    Sectional Hydrostatic Testing

    Simply put, sectional hydrostatic testing involves dividing the entire system into smaller sections or segments and testing each section individually.

    At PTS, we choose this approach for large or complex systems. Naturally, testing the entire system at once can be impractical or challenging. It all depends on the water system and pipework we are working with.

    Here are several benefits and factors that we considered when opting for sectional testing. Let’s take a look:

    However, carrying out sectional hydrostatic testing is no without its challenges:

    Complete System Hydrostatic Testing

    Now let’s turn to the alternative, a complete system hydrostatic pressure testing:

    As you may guess, complete system hydrostatic testing involves testing the entire pipeline, vessel, or system as a single unit. Crucially, without dividing it into sections. Muchlike its counterpart, this approach also offers advantages. At PTS, We carefully evaluate our methods based on the specific project requirements.

    Advantages of Complete System Testing

    Considerations for Complete System Testing

    Increased Water or Test Medium Requirements

    Testing the entire system necessitates a larger volume of water or test medium to fill the system, potentially increasing costs and logistical challenges.

    Higher Potential Impact of Failures

    A failure during the test could have more significant consequences when testing the complete system, as the entire system is subjected to the test pressure.

    Complexity for Large or Intricate Systems

    For very large or complex systems, testing the entire system as a single unit may be challenging or impractical due to limitations in access, setup, or testing equipment capabilities.

    Determining the Appropriate Approach

    including the size and complexity of the system, accessibility considerations, risk assessment, and project-specific requirements.

    In some cases, a combination of both approaches may be employed. With critical sections tested individually and the complete system tested as a final step.

    Several key elements should be considered when determining the appropriate testing approach:

    System size and complexity

    Larger or more intricate systems may benefit from sectional testing due to logistical challenges or limitations in testing equipment capabilities.

    If certain sections of the system are difficult to access or isolate, sectional testing may be necessary to evaluate those areas effectively.

    A thorough risk assessment should be conducted to evaluate the potential consequences of a failure during testing and determine the appropriate testing approach based on the identified risks.

    Applicable industry standards and regulations may provide guidance or requirements for hydrostatic testing methods, which should be carefully reviewed and followed.

    The time and resource constraints of the project may influence the chosen testing approach, as sectional testing can be more time-consuming but may require fewer resources compared to testing the complete system.

    By carefully evaluating these factors and weighing the advantages and considerations of each approach. Our team can make an informed decision on whether to perform sectional or complete system hydrostatic testing.

    Regardless of the size and scale of the job, we’ll ensure the most effective, and cost-effective, method for efficient testing.
