Statutory Inspection Activities
* Only personnel suitably qualified and certified competent as per the relevant Act should perform activities consisting of internal and external inspections and pressure testing. During this operation the condition and calibration of the safety valves as well as the applicable pressure gauges are also checked. Safety valves will be adjusted if required, either on-site or at an independent facility if so required. Problem areas are identified, and plant management is assisted to determine potential failure trends.
* Pneumatic pressure testing, chemical or high-pressure cleaning and various other maintenance activities can also be conducted by arrangement.
* Re-certification of uncertified equipment and repair activities by means of welding can also be arranged and managed.
