Temperature and pressure of a surface the choose and buy of common sense

Industry develop very quickly now, for the sake of the real-time monitoring of temperature and pressure in the piping, pipe are often used to the temperature and pressure on surface, so how to choose and buy? 1, installed on the boiler or pressure vessel for the temperature and pressure of a surface, the choose and buy is to be consistent with the relevant equipment on the pressure gauge. 5 ~ 3 times, the best temperature and pressure to select 2 times a body surface, to avoid the overpressure damage. 2, for using precision pressure gauge, a body surface temperature and pressure, the choose and buy is according to the installation of the equipment level of stress to the choose and buy. 3, when using a body surface temperature and pressure, if the use of space has certain corrosion, so, we in the choose and buy when, must according to the state of corrosion, to choose different material, otherwise will cause damage to pressure gauge, so that the measured temperature is not accurate. The last reminder, in addition to the choose and buy, for use in the production of temperature and pressure of the body surface, we suggest that in the process of using regular maintenance.
