Baker Hughes is headquartered in Houston.

On 14 July 2021, Baker Hughes inquired about a temperature test chamber through LIB’s England agent. Its specimens are oil drums for underwater surveys, which are large and heavy. In addition, specimens needed to be tested for their performance under the situations of temperature and pressure simultaneously. So, we designed equipment---T-4500B for Baker Hughes and opened many holes in the workroom of the equipment to connect the tube for injecting pressure into the workroom. To place oil drums in the equipment conveniently, we also designed a window above the equipment which can be opened by the controller. T-4500B is working in their lab now.
