Ultrasonic Thickness Measurement
SHIP THICKNESS GAUGING
Structural Assessment of Hull Structures.
We have been associated by Class ABS, LRS, DNV, BV, GL, IRS, NK, KRS and RINA for carrying out thickness gauging towards owners assessment/ annual/ intermediate/ special/ CAS/CAP surveys.
Our well experienced team carries out marine structural examination and Ultrasonic surveys for vessels at sea, in port and dry dock. We provide repair/ renewal specification to steel structure of the vessel and marking of the steel for renewal. We are competitively priced and same basis lump sum cost or per pointto suit our customer requirements.
Thickness Gauging for Industrial Applications
Pipelines
An extensive pipeline network exists around the world for transporting oil, gas and chemicals. A damaged pipeline will not only have a severe environmental impact but may also result in injury to personnel. Furthermore, it may also lead to long and expensive down times. Ultrasonic thickness surveys and Inspections on pipelines can be costly and time consuming due to the sheer size of them. The ruggedness of the gauges means that they can endure the harsh environments in which pipelines areoften located.
Road Tankers
Road tankers corrode and erode from the inside out, and regular inspections are required to prevent accidents from happening. It is usual to measure the top, bottom and sides of the tank, as well as the knuckle ends, to identify areas of thinning before accidents occur. Inspections are normally carried out by road tanker refurbishment companies, inspection companies and also in house by largehaulage companies.
Storage Tanks
Storage tanks can contain anything from water to chemicals to petroleum, and in each case it could be extremely damaging if an accident occurred due to excessive corrosion. Also, LPG tanks are susceptible to corrosion and require regular thickness measurements to assess their condition. The multigauge 5500 is ideal to wear on the waist belt for rope access surveys or for climbing ladders or scaffolding.
Bridges
All bridges have a structure based on steel frames and supports. Some are completely encased in concrete and others have the metalwork exposed. It is essential to carry out maintenance checks to assess the serviceability and structural strength of the bridge. Routine inspections vary from a 2to 6 year cycle depending on the bridge type. The range of gauges cover all aspects of bridge inspection from inspecting the footings underwater to carrying out rope access surveys. The Multigauge 5700 thickness measurement gauge allows measurementstobestoredthegaugesothat routineinspections canbetaken.
Lighting Columns
Lighting columns are susceptible to corrosion at the base, due to splashes and
ground water, and the collar (swage joint) often due to condensation built up
inside the column. Regular inspection of lighting columns using a thickness
measurement gauge is recommended to ensure they are maintained in good
condition and are structurally safe to prevent the column from collapsing and
causing possible injury. Local governments and authorities are usually required to
carry out thickness measurements on a regular basis along local roads and
highway networks.
Measurments are typically taken, using a thickness measurement gauge, at four points around the circumference at different heights on the lighting column.
General Industry
Most factories have reserves of chemicals stored in tanks to allow them to carry out their respective processes. These are generally transferred around site using pipelines. Both the tanks and pipelines are susceptible to corrosion and can be kept in check with simple thickness monitoring. Other applications may include wear on machinery, boiler tube measurement, quality assurance, inspection of metal structures, condition monitoring of plant assets or preventative maintenance. Inspection of refineries is essential to prevent accidents from occurring.
