全球压力容器市场报告(2017-2021年)
A pressure vessel is a mechanical device, designed to store liquids or gases at specific
pressure points in closed containers. The pressure applied is considerably different
from the ambient pressure. These devices are widely used in many industrial
applications, and they generally appear as industrial compressed air receivers and
domestic hot water storage tanks. Other examples of pressure vessels are autoclaves,
distillation towers, diving cylinder recompression chamber, vessels used in mining or oil
refineries, nuclear reactor vessels, and petrochemical plants. In addition, pressure
vessels find their applications in hydraulic and pneumatic reservoirs under pressure,
rail vehicle airbrake reservoir, and storage vessels for liquefied gases, such as
ammonia, chlorine, and LPG.

全球浪涌保护器件市场报告(2017-2021年)
Surge protection devices are used in electrical installation protection systems. This
equipment is designed to prevent the flow of excess voltage into the circuit. Whenever
there is a flow of overvoltage, the surge protection device transmits the excess current
flow to the earth and thus protects the electrical appliance.

全球隧道和凿岩设备市场报告(2017-2021年)
The tunnel boring and rock drilling machines are used to excavate holes for tunnels
through different kinds of soil and difficult rocky terrains as an alternative to
conventional blasting methods. Machines operate effectively by reducing the
disturbance to the ground while boring through any difficult terrain. Typically, a tunnel
boring and rock drilling machine comprise a rotating cutting wheel, followed by the
main bearing, trailing support mechanisms, and a thrust system. Based on the
geographic terrain of the region, different types of tunnel boring and rock drilling
machine are used. As the machine functions smoothly, it is majorly used in highly
urbanized areas to complete drilling work in less time. However, the upfront cost
involved to assemble the equipment and difficulties experienced while transporting
them across different sites is one of the main drawbacks of the tunnel boring machine
(TBM).
