Regarding the design pressure of pipes and reactors, which is higher?
Thread Content
Generally, the design pressure of pipelines is higher than that of equipment; therefore, the design pressure of a hydrogenation reactor should be lower than the pressure in the inlet and outlet pipelines. But since the wall thickness of the reactor, the thickness of the flanges, as well as the stress on bolts and gaskets, are all greater than those in the pipelines, how should this be understood?
I have no experience with hydrogenation equipment, but is the diameter of the equipment the same as that of the pipes?
It seems incomprehensible when the flange thickness of the thermocouple on the reactor is significantly greater than that of the flanges used for feeding and removing material from the heating furnace tubes, while the diameter of the thermocouple’s flange is smaller
The main difference lies in their design lifespans: the reactor has a lifespan of 30 years, while the pipes have a lifespan of 10–15 years
Do you know who designed it? Some design institutes prefer to use thicker flanges for instrument nozzles*, which is a common issue*.
