Pipeline characteristics
1, the pressure pipeline is a system, mutual correlation with each other, led by a move the body.
2, the pressure pipe length to diameter ratio is very easy, easy to instability, the force situation is more complicated than the pressure vessel. (Such as high temperature, high pressure, low temperature, low pressure, displacement deformation, wind, snow, earthquake and so on are likely to affect the pressure pipe force situation). The pressure flow in the pipeline is complicated, the buffer is small, the working conditions change the frequency higher than the pressure vessel.
3, pipe fittings and pipe support a wide range of various materials have their own characteristics and specific technical requirements, the use of complex materials.
4, the pipeline may leak more than the pressure vessel, only one valve usually has five.
5, the number of pressure pipes, the number of large, design, manufacture, installation, testing, application management and more links with the pressure vessel is very different.
Pressure level division criteria
Low-pressure pipe 0 ≤ P ≤ 1.6MPa
Medium pressure pipe 1.6 <P≤10MPa
High pressure pipe 10 <P≤100MPa
Ultra High Pressure Piping P> 100MPa
