Regarding the issue of burying the alkali tank underground
Thread Content
One of the new projects in our company features a 20% alkali solution tank that is designed with external insulation and external coils, but the equipment itself is designed to be buried directly in the ground! Is there a conflict? What issues need to be considered when burying it directly? ? How to prevent corrosion? ? We are in the oil refining industry, and we have come to this forum specifically to ask the experts in the chlor-alkali field for their help!
Same question: how should insulation be done for buried tanks?
Same question: How is insulation provided for this buried tank with external coils? Should a rigid insulation material be used?
At present, electrocorrosion needs to be taken into consideration. Moreover, most applications now require double-walled tanks; for corrosion protection, asphalt-glass cloth is used for enhanced protection, which will suffice for 15 years without any problems
