Using under pressure drilling techniques our technicians are able to determine the condition of the internal parts of valves and pipes using bore scopes and video scopes so that a thorough assessment of their condition can be made and a solution proposed if required. Our techniques currently allow us to prove that a valve is seizing or leaking by using bore scopes, if picture evidence is required. Alternatively, by using the latest technology, we now have the ability to obtain this information without invasive means.
