Discussion on issues related to the installation of hoses connecting storage tanks
Thread Content
The tank’s inlet and outlet are equipped with two valves, one manual valve and one automatic valve. So the question is: where should the hoses be installed? 1. The inlet and outlet pipelines both use: storage tank – hose – manual valve – automatic valve – inlet/outlet pipeline. 2. The inlet and outlet pipelines both use: storage tank – manual valve – automatic valve – hose – inlet/outlet pipeline. 3. The inlet and outlet pipelines are arranged differently; for feeding, it uses: feed line – automatic valve – manual valve – hose – storage tank, while for discharging, it uses: storage tank – manual valve – automatic valve – hose. Are there any other scenarios? Welcome to the expert’s insights

Stepping stones should be provided between valves for operating and maintaining them
The storage tank is a stationary device; a rigid connection is used between the valve and the tank, while a flexible connection is used with external devices
It’s best to include a flowchart, as visual aids make the explanation more accurate. The hoses that are connected usually serve as temporary conduits for the inlet and outlet of materials. Automatic valves shouldn’t have anything to do with this, right? ? Let’s add a process diagram instead. To avoid guessing games: lol
Both inlet and outlet pipelines use: ········· storage tank – manual valve – automatic valve – hose – inlet and outlet pipelines. Alternatively: For both inlet and outlet pipelines, the configuration is storage tank – manual valve – hose – automatic valve – inlet and outlet pipelines. The key is the position of the hose; its function is to prevent the storage tank from sinking and causing the connection between the pipeline and the tank body (the weld) to tear.
Hoses are used to prevent pipes from being torn due to the settlement of storage tanks. I believe the use of hoses depends on the size of the inlet and outlet valves; if the valves are small, manual valves can be installed directly on the storage tank since no additional support is needed. If the valve diameter is large and the weight is significant, it’s better to use hoses to connect the valve to the storage tank, so that each valve can have its own support system, thereby avoiding damage caused by settlement. Is this understanding correct?
That makes sense. Small valves do not require support
It’s explained very clearly, and it’s easy to understand too
The second one; the specific specifications are unknown, it’s just done that way on site.
Storage tank + manual valve + automatic valve + hose. The reasons are as follows: 1. A manual root valve must be installed after the storage tank, and it normally remains closed and does not operate. 2. An automatic emergency shut-off valve is installed directly after the manual valve; in the event of a leak in the pipeline, it can automatically shut off the flow via the DCS, thereby preventing the leak from spreading. 3. The hose may leak, so it is installed behind the automatic emergency shut-off valve. It should be noted that the supports for manual and automatic valves need to be placed together with the tank foundation.
