API are specialists in undertaking pressurised water pipe inspections using PIPA Technology. Pipe inspections are based on 3 categories:

• Pressurised push rods
• Floating systems
• Pulley driven systems

Pressurised push rod CCTV & leak detection surveys via boundary box & tappings

Service pipe inspection (live CCTV & acoustics) small sized pipes 25mm and above

Our site implementation teams are qualified to utilise PIPA unique designed camera systems, these are fully chlorinated and operated under live mains pressure into potable water mains.
The system includes a small camera or acoustic sensor attached to a 50 metre flexible nylon control cable and seal arrangement, which can be inserted into a metre boundary box or direct tapping to inspect potable water mains and determine the internal condition.
This system provides a live images and acoustics for teams working above ground, and covers a distance of up to 50 metres towards a property or boundary, allowing them to survey the pipeline without the need for excavation, or interruption to customers supply. All PIPA systems can be traced to map pipe positions and to update GIS records.

Live fire hydrant entry CCTV surveys (type 2 fire hydrants)

Our site implementation teams are qualified to utilise PIPA unique designed camera systems, these are fully chlorinated and operated under live mains pressure into potable water mains.
The system includes a small camera, attached to a nylon control cable which can be inserted into a fire hydrant to inspect potable water mains and determine the internal condition, size of main, linings and pipe material.
This system provides a live image for teams working above ground, and covers a distance of up to 25 metres in either direction, allowing them to determine whether the main is suitable for lining and investigate sediment levels without the need for excavation.

Implementation of the system has many benefits to the environment, asset owners and customers:

• Elimination of excavations
• 93% Less carbon footprint through non-excavation
• Less water loss through quicker identification and repair
• 93% cost savings over conventional processes
• Improved timescales of operations and all deliverables
• Identification of water discolouration causes and locations
• An integral part of operational due diligence systems
• Audits the need for asset pipeline replacement
• Enables future budgets and time lines for water mains renewal programmes

Pressurised push rod CCTV & leak detection surveys via through bore hydrants & tappings

DMA mains inspection (live CCTV & acoustics) medium sized pipes 2 inch and above

Our site implementation teams are qualified to utilise PIPA unique designed camera systems, these are fully chlorinated and operated under live mains pressure into potable water mains.
The system includes a small camera attached to a 100 metre flexible nylon control cable and seal arrangement, which can be inserted into a through bore fire hydrant or direct tapping to inspect potable water mains and determine the internal condition.
This system provides a live images and acoustics for teams working above ground, and covers a distance of up to 100 metres in either direction, allowing them to survey the pipeline without the need for excavation, or interruption to customers supply. All PIPA systems can be traced to map pipe positions and to update GIS records.

The revolution in recent hydrant styles has enabled API to continue to lead the industry in live potable water pipe inspections.

The through bore fire hydrant enables the utility to utilise this asset for all types of insertion technology.
We in turn have developed our systems to be suitable for the new style hydrants by:

• Increasing the size of the camera head
• Adding greater illumination
• Increasing the sensors radial view
• Utilising a more rigid tether to improve inspection distance
• Adding a hydrochute to pull sensor over longer ranges wen required

This system provides a live image & acoustics for teams working above ground, and covers a distance of up to 100 metres in either direction, allowing them to determine whether the main is suitable for lining, requires cleaning or has leaks without the need for excavation.

Case studies to date are:

• Investigating pipe wall condition
• Specialist leak detection
• Material validation
• Pre and post cleaning validation
• Internal validation of pipeline installation/lining projects
• Sediment issues
• Seeking ferrules
• Live valve assessments
• Location of foreign objects
• Location of blockages or closed valves
• Pipeline configuration surveys, prior to lining projects
• Reasons for water discolouration / water quality issues
• Life expectancy of the pipe
• Condition assessment
• Mains renewal prioritisation
• Asset management budget Validation

Other Benefits

• GPS tracking and plotting
• Direct Import of data to GIS
• Attachment of video to GIS
• Validation of Asset management plans
• Audit trail of Asset management budgets
• Location of unknown mains locations
• Commissioning of new pipelines with hydrophone testing and CCTV to validate QC

Asset condition assessment surveys

API can offer an all-round solution in asset assessment delivery by offering a wide range of pipe inspection services.
We have inspected thousands of pipelines not only in the UK but also overseas, In many cases the utility has had issues with networks for periods of up to 30 years, API has removed the guess work and within a single day traced the source and resolved the issue.

Complete condition surveys for asset management on all types and sizes of pipe work. This allows validation of material type, linings, visible sediment and identification of assets.
The system enables inspection surveys up to a maximum distance of 5000 metres in one direction.
The systems are designed to be inserted into fully pressurised mains via many entry points, including through bore fire hydrants, valves and quadrena fittings.

Assessment

• NDT Asset Condition (external wall thickness assessments)
• Life Expectancy Assessment
• Asset Lifecycle
• Coupon Analysis
• Asset Risk
• Stress Corrosion
• Long Seam Cracking
