Pressure Testing

INTRODUCTION

At AHS Pipeline Innovation, we not only offer expertise, in-depth analysis, and certification, but we also actively shape industry standards. As key contributors to the development of the new WIS 4-01-03 specification, our services reflect the latest in regulatory requirements and best practices.

Pressure testing helps identify faults, leaks, and other defects before they become expensive, time-consuming issues later in the project or once the asset is in service. During a test, a defined section of pipework is subjected to water pressure above its normal operating level for a set period. Integrity is then confirmed by monitoring key test conditions including pressure, air content, flow volume, and temperature.

To deliver safe and accurate pressure tests, our specialist equipment is designed, built, and maintained by AHS engineers, ensuring dependable performance and high safety standards on site. Every test carried out using AHS equipment is also overseen by our in-house Pressure Testing Analysts, who monitor performance in real time, verify results against WIS 4-01-03 standards, and issue digital certification through our PIPE dashboard. This ensures every test is consistent, traceable, and fully compliant.

Our Pressure Testing SOLUTIONS

Whether you choose to hire equipment directly or work through our Approved Contractor Network, AHS ensures every test is delivered to the same high standard — safe, accurate, and right first time.

Direct Hire

If your team is experienced in preparing pipelines for hydrostatic pressure testing, Direct Hire offers a cost-effective and flexible route to WIS 4-01-03 compliance.

AHS supplies all required equipment, with every hire kit tested and validated by our in-house engineers for safe, reliable performance on site. Once your equipment is in place, simply prepare the pipeline and contact us when you are ready to begin.

An AHS Pressure Testing Analyst will monitor the test in real time, guide you through the process, and provide support by phone or video if needed. Once complete, your data is reviewed and certified through the PIPE dashboard, giving you instant access to results and documentation.

Approved Contractor Network

If you need on-site setup and delivery, AHS can coordinate your test through our Approved Contractor Network. Our trusted partners use AHS-approved equipment and follow the same safety and compliance standards.

We match your enquiry to suitable contractors based on your project and location. While the contractor prepares the pipeline and carries out the test on site, AHS Pressure Testing Analysts monitor live data and provide expert support throughout.

Once complete, AHS reviews and certifies the data through the PIPE dashboard, ensuring results are fully compliant with WIS 4-01-03.
