Pentane unloading pipeline
Thread Content
The straight-line distance of a pentane unloading pipeline is approximately 15 meters, running from the unloading dip pipe to the discharge pump; however, there are two other pipes in this section of pipeline. In order to bypass these two pipes without affecting the operation of the other two pumps, the owner wants to arrange the pentane pipeline in a \"Z\" shape to go around them. The highest point of the character “ several” in the pipeline is approximately 3m. 1. What I want to ask is whether this is feasible? 2. Does arranging the pipes in a “ several” shape have any impact on the pressure in the pipes?
Construction companies like it; the volume of work increases, and costs rise. What diameter should the pipes be? However, the construction cost for diameters below Dn100 is not high. Generally, such pipes are routed along the steel beams in the loading/unloading shed; it’s necessary to discuss whether installation at specific points is really required. As long as safety is not compromised, adding elbows and short pipes to bypass those areas will suffice – there’s no need for waste
1. The liquid accumulated in the “J” shape from the unloading crane pipe cannot be completely pumped out. 2.Cavitation may occur
I can understand that there is fluid accumulation that cannot be completely drained; is cavitation occurring at the discharge pump? Why does cavitation occur? Could you explain it? Thank you :)
It’s a DN80 pipeline; it wasn’t the requirement of the construction party, but rather the decision of the project owner. As the design firm, I need to consider whether the requirements put forward by them can be met. Are you saying it’s okay as long as safety is not compromised? If we use elbows and short pipes to avoid it, I think it should be the same as using a \" several \"-shaped pipe, right? So how can it be done without compromising safety?
From the unloading dip pipe to the discharge pump, that is, the inlet pipeline of the pump, you can calculate the additional pressure drop.
