Position of tank nozzle
Thread Content
Gentlemasters! I would like to ask about the considerations regarding the placement of pipe connections on storage tanks in tank farms. It would be great if you could explain why certain locations are chosen for things like material inlets and outlets, manholes, level gauge ports, and ladders
The orientation of the tank area outlets is generally determined based on process requirements, taking into account the convenience of piping and a simple flow setup.
Your question is too general; storage tanks include spherical tanks and cylindrical tanks (vertical, horizontal). Which type are you referring to? The internal medium, the pressure inside the pipe, etc. – it would be best to describe these clearly so that everyone can discuss them.
What is being made now are vertical atmospheric pressure tanks and horizontal atmospheric pressure tanks
Manholes, safety valves, level gauges, thermometers, and discharge ports must have their locations determined based on the actual piping layout. This involves aspects of the process plan, with some elements related to civil engineering, water resources, mechanical and electrical systems, etc.; please proceed with caution.
Apart from the requirements mandated by standards, the orientation of pipe openings is determined based on process piping considerations; for example, petrochemical standards require that inlet and outlet pipes for materials of type A, B, and C be located at the bottom of the tank
The pipe outlet orientation is that of the piping-equipment
It is generally divided into the operation side and the maintenance side, with the pipe openings mainly concentrated in the operation side area.
For materials A, B, and C, the inlet and outlet are both at the bottom of the tank – is this a mandatory requirement?
It mainly refers to Regulation 6.2.24 of the petrochemical standards; the responses given casually are not standardized either. If you have any doubts, it’s better to consult the regulations directly
