Compact® is GUL's latest guided wave transduction system for pipeline inspections. The versatile design of the Compact® system represents significant improvements over our standard inflatable range transduction system. While building on everything that has gone before in order to maintain the overall superb standard of the GUL guided wave system, the new Compact® system has been completely re-engineered to reduce the weight by 35% and the axial width by 30%. It reduces the radial height clearance to under 38mm. This is an inspection system designed to ensure effortless operation while tackling a wide range of inspection challenges, from refinery pipe racks to restricted access road crossings.
