Ultrasound tests on metals - Import export

SDT was the first to pioneer on ultrasound-based hatch cover weathertightness testing on board of ships back in the late 1980s. Together with MacGregor, Lloyds Register of Shipping and IMCS, SDT was able to put ultrasound testing of hatch covers on the world map and make it the preferred method for testing hatch covers by charterers, shippers, P&I insurers and stakeholders in the marine industry. Another first position for SDT is that further development of the tightness testing equipment resulted in SDT launching the world’s first Class type approved and bespoke SHERLOG product range in 2000. Ever since, the SDT SHERLOG equipment became a symbol of reliable and professional hatch cover testing. As no solution is complete without training, SDT & IMCS developed the first and only training course for ultrasound testing of hatch covers in line with the IACS UR Z17 criteria.

Non-rotating asset components seldom receive the routine surveillance they need Hydraulic systems represent another way industry converts electricity to mechanical energy. A pump, normally powered by an electric motor, moves hydraulic fluid through a system. The system is typically made up of a reservoir to hold the hydraulic fluid, high pressure lines to carry the fluid, control valves that ensure the fluid is sent where needed, relief valves for safety, and cylinders to produce mechanical energy. The pump and motor receive attention while the balance of the system is run-to-failure. Ultrasound testing could change this lackadaisical approach; especially considering its versatility, ease of use, and applicability to most hydraulic defects. External and Internal Leaks External leaks can often be found by visual inspection. Some external leaks, like a ruptured hose or fitting, are easy to spot. Simply follow the trail of spilled oil. Others are not so obvious.
