Products and Services


Leak Testing
Helium leak testing with laboratory standard based mass spectrometer is recognized throughout the world as the only method for quantifying a leak. CCS offer both Air / Helium and Nitrogen / Helium testing options for new build construction on Hydrocarbon systems.



Inspection Services
Existing piping systems in service that are affected by contaminants, organic and inorganic scales will suffer reduced flow rates or affect heat transfer. We can offer tailored chemical cleaning and retrojet services for most new build and existing systems on a case-by-case basis.


CCS supply Spool piece Hydrotesting as part of our pre-commissioning package. CCS can also reinstate spools instead of Hydrotesting if piping modification takes place prior to final leak test. This ensures structural integrity which in turn increases safety to all personnel and minimises barriers around test areas allowing for simultaneous operations in a construction area.
