Millions of pounds are being wasted in lost production time as a result of industry failing to inspect pipework thoroughly.
According to Peter Jagger of Phoenix Inspections Systems Ltd, a specialist in non-destructive testing, too many disruptions are caused by leaks or blockages which could have been prevented by accurate monitoring.
"The problem is that even where pipework is inspected this isn't carried out in a regimented fashion,"says Jagger. "Most firms rely on smoke bombs, water flushing or objects passed down the pipe or simply banging on the side of it with a hammer. These traditional methods fail to provide any record or give the operator any idea of the internal condition."
A simple sonic device produced by Phoenix claims to offer a solution. The Acoustic Ranger Hole and Blockage Detector emits a sound wave which runs along the inside of the pipe,following it around bends and even complex spirals. It can detect and locate holes, blockages or foreign bodies in up to 500 metres of tubing at inspection rates of up to 800 tubes an hour.
This system reportedly requires no dismantling of pipes and uses existing break-in points. It offers greater accuracy and substantial time savings over conventional techniques,along with the added advantages of data information storage on disk and printed hard copies.
Current health and safety regulations demand that all vent lines are checked but fail to specify an exact method. The Acoustic Ranger Hole and Blockage Detector has enjoyed widespread popularity in the nuclear and petrochemicals sectors, where users like BASF,BNFL and ICI need to maintain high safety standards and appreciate the value of accurate diagnosis and recording of faults.
