  • Why Water Scale is Dangerous for Equipment

    Mineral scale occurs wherever circulating water exists, and it forms very fast (generally less than 3 weeks). Even a very thin layer, it will also cause insulation, make equipment inefficient, increase cost, and in some serious cases, it will shut down the whole system and even cause explosion. These problems have already existed in different fields, and are becoming worse and worse. ...

  • Water hammer (hydraulic shock) causes and preventative measures

    Water hammer (or hydraulic shock) is the momentary increase in pressure inside a pipe caused by a sudden change of direction or velocity of the liquid in the pipe. Water hammer can be particularly dangerous because the increase in pressure can be severe enough to rupture a pipe or cause damage to equipment. Therefore, the proper opening and closing of valves is fundamental to safe pipeline ...

  • ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible for costly replacement of piping and equipment by corrosive attack on metah. what is Dissolved Oxygen? Dissolved axygan (D.O.f is the ...

  • Analytical Devices for the Measurement of Water Vapor in the Natural Gas Process and Transmission Industry

    ABSTRACT The determination of water vapor (and water dew point) is crucial in the processing, custody transfer and transport of natural gas. High levels of water vapor in a natural gas stream can lead to a number of problems which include the formation of hydrates and the contribution to freezing and corrosion of plant and equipment. There are a number of ways of determining the water vapor ...
