Test Procedure

Confirm Project Information

Pipelines to be inspected and their details
Testing specification requirements

Initial Work Area Inspection

Is test area barricaded off or sufficiently delineated?
Is traffic control established?
Has a Safe Work Method Statement been completed and all control measures followed?
Has a Confined Space Risk Assessment & Entry Permit been completed?
Is the confined space equipment and procedures set up as per the Risk Assessment & Entry Permit conditions followed?
Structure lids removed and placed at a safe distance from the entry point
Environmental controls installed as and if required

Inspection Steps

Equipment checked and in good working order
Insert test plugs into the structure inlets with extendable pole if possible so confined space risks are avoided
Inflate plugs and add support as per manufacturer's specifications
Attach bypass plug to vacuum pump and vacuum down pipeline to test pressure
Allow for vacuum to stabilise for an amount of time as per specifications
Hold vacuum for time specified in specifications and record result

Disassemble Steps

Disconnect hose from vacuum pump and release pressure from pipeline
Release pressure from plugs and carefully retrieve plugs out of structure
Replace structure lids, remove barricading and return all items to test unit

Final Demobilisation

Notify client of results and to contact TestX office to arrange further testing or reports
Calibrated gauge numbers used
