CCTV Inspection
Pipeline CCTV inspections

Earlier evidence.
Better temperature compensation.
Auditable results.
APT pneumatic testing uses acoustic temperature measurement to determine average temperature changes in the air inside a pipeline. The test software combines this information with pressure data and creep compensation to help distinguish temperature effects from leakage during large-volume pressure tests.
-
Earlier leak discrimination
-
Digital auditable test records
-
Automatic test-certificate generation
-
Reduced conditioning and overall test time where applicable
Specialist support when network continuity matters
MTS Contracting Ltd supports emergency works arising from third-party damage and system failure. In-house capability includes PE squeeze-off and stocked 7 bar IP materials for pressure points, bypasses and vents. Through specialist delivery partners, the available response can extend to stopple, bag-off, IRIS, drilling, window cuts and branch saddles.
