Installation of metal flexible hoses for inlet and outlet pipes of small storage tanks
Thread Content
1. The maximum volume of the small storage tank (intermediate tank) is approximately 78 m3, and the medium contained is acetate. Are metal hoses required for the inlet and outlet pipes of this tank? 2. The seismic intensity at the location where this storage tank will be built is 8 degrees. In accordance with the \"Design Manual for Oil Storage and Transportation,\" it is necessary to take earthquake effects into account when selecting the length of the hose corresponding to a compensation amount of ±200 mm The structural team has done a rough estimate: the maximum settlement of this tank is <30mm ； 3. If a metal hose is chosen in accordance with Article 2, it will be very long; coupled with the requirement that flammable liquids must be transported in separate containers, this increases the difficulty of piping installation significantly ；
Wouldn’t it be better to use a hose as a compensation element, combined with a fixed rigid pipe?
Whether it’s an earthquake or subsidence of the ground, the main concern is actually potential stretching issues with the pipelines; using metal flexible hoses is a great solution—whether it’s a small storage tank or not. However, before deciding to use metal flexible hoses, it is necessary to pay attention to the internal material, operating pressure, and the use of the external stainless steel woven mesh.
