Inspections Services
Inspection and cleaning of (fire extinguishing water) pipes (pigging). Measuring and checking cables. Visser & Smit Hanab is a specialist. From making pipes piggable to pipe inspections and cleaning. We`re happy to help prevent faults and unnecessary maintenance.
Intelligent pigging
Pigging is cleaning and drying pipes using a foam rubber `sponge` that moves through the pipe. A `train` of modules behind the sponge turns it into an intelligent `pig`. This `pig` measures the wall thickness and the extent of the corrosion from the inside. Intelligent pigging is a less expensive and quicker alternative to digging up pipes.
Pig traps
Many pipes are not `piggable` as standard. There are no facilities to launch a pig and then retrieve it. As such, Visser & Smit Hanab developed mobile ‘pig traps`. High-pressure vessels that are temporarily mounted to a pipe and which, in theory, make it possible to pig every pipe larger than 4 inches. Based on the data that the pig gathers, a maintenance plan for corrective and preventive maintenance .
