What is a pressure pipe
     From a broad sense, the pressure pipeline is all to bear the internal pressure or pressure of the pipeline, regardless of how the tube medium. Pressure pipeline is a part in the pipeline, the pipeline is used to transport, distribution, mixing, separation, emission, measurement, control and stop the flow from the pipe and pipe fittings, flanges, bolts, gaskets, valves and other components or compression components and support components of the assembly.
     Characteristics of pressure piping
      1, the pressure pipeline is a system, interrelated and mutually influence, pull one hair and move the whole body.
     2, the long diameter ratio of the pressure pipe is very large, it is very easy to lose stability, the stress situation is more complex than the pressure vessel. The complicated flow state of the fluid pressure inside the pipeline, buffer, frequency change working conditions than the high pressure vessel (such as high temperature, high pressure and low temperature, low pressure, displacement, wind, snow, earthquakes are likely to affect the pressure pipeline stress).
     3, pipe components and pipe support a wide variety of materials, various materials have the characteristics and specific technical requirements, material selection complex.
      4, the pipeline may leak point more than the pressure vessel, only one valve usually has five.
      5, many types of pressure pipeline, the number of large, design, manufacture, installation, inspection, application management links, and the pressure vessel is not the same.
