In the pipeline safety relief device, the safety relief device of lsaw steel pipe indicates that the pipe may appear in the running process beyond normal working pressure.The purpose of setting up the safety relief device is to automatically release the pressure to protect the hardware of the equipment and piping system under the pressure of the normal working system.The design pressure of the lsaw steel pipe shall not be lower than that of the safety relief device.
There are high lift pumps in the lsaw steel pipe, especially the reciprocating pump, and sometimes the confining pressure can achieve great value. Outlet pipeline pump, pressure pump design should be the maximum confining pressure value.
Vacuum system, the pressure of the vacuum system pipe is the external atmospheric pressure, so the design pressure is 0.1 MPa external pressure.
Corrosion resistant longitudinal welded pipe, when the pipe has a higher liquid liquid column, should also consider the influence of the static head.In fact, straight seam welded pipe and equipment than complex force, this is, because it is not only the influence of the secondary load, but also often suffer due to the heat bilges cold shrink pipe force, etc, therefore, anticorrosive straight seam welded pipe design of straight seam welded pipe pressure generally should not be less than the design pressure of the equipment.
The most serious condition: determination of the design temperature: considering the environment, heat insulation, operation stability factor.For example, the design temperature shall be a little higher than the internal pressure (or external pressure) and the most demanding conditions of temperature constitute the highest operating temperature.
