Tungsten Alloy Shielding In Industry

Tungsten Alloy Shielding In Industry Picture

Geologging is an exploration technique used mainly in the oil and gas industries. It is also known as wire line logging and borehole logging. A gamma ray source is lowered into a borehole and the radiation penetrates the rock strata. This data can then be analysis to determine whether deposits of gas or oil are present. Tungsten alloy is used to shield the radioactive source and to act as a collimator for the gamma beam.

Pie-line inspection
Radiation is used to inspect welds and to detect cracks in pipelines. A gamma source is mounted on a remote-controlled wheeled trolley (sometimes called a "pig") and travels inside the length of the pipe. A WOLFMET tungsten collimator is used to direct the radiation onto the target, whilst the radioactive source is housed inside tungsten shielding

Storing and transporting radioactive material
Though lead has long been used for storing and transporting radioactive material, but it creates environmental hazards. Further, relatively large amounts of lead are required for effective shielding. Tungsten alloy, on the other hand, are the perfect solution: They used in collimators, isotope shipping containers, gamma cameras, cobalt teletherapy machines, nuclear reactors and more. And they are environmentally friendly, and they are 50% more dense than lead, providing more effective shielding with less material.

Industrial radiography
Industrial radiography uses gamma radiation to detect structural faults in materials such as metal and concrete. As with pipe-line inspection the equipment uses tungsten shielding, coupled with a tungsten alloy collimator. Thickness, density and level gauging radioactive sources are used in industrial processes to measure thickness, density or levels of materials during production e.g. paper, plastic film, steel sheet or surface coatings. The material passes between a radioactive source, which is housed in tungsten alloy, and a detector. The strength of the detector signal is used to measure the thickness, density or level of the material.

Tungsten Alloy Plasma Accelerator Shielding
As radiation becomes a problem. To protect body from radiation is very important. Radiation shielding for plasma accelerator is quite necessary. Depending on heaviest density but smallest capacity, tungsten alloy material is more and more popular be used for making tungsten alloy shielding to protect body from plasma accelerator radiation. Compared with lead, tungsten is much smaller but with heavier density, which is very helpful for high radiation absorption. It is more than 60% denser than lead, meanwhile, it has excellent machinability, good corrosion resistance. The most important thing is that, tungsten material is environment-friendly.
