The "Code for Design of Thermal Insulation Engineering of Industrial Equipment and Pipelines" recommends that the medium temperature fluctuation of tank heat tracing systems should be controlled within a reasonable range. In on-site operation and maintenance, problems are often encountered such as local overheating of heat exchangers causing oil cracking, or condensation causing reduced heat transfer efficiency. The SLR-25 jacketed heat exchanger adopts a metal jacket structure and can be evenly arranged in groups according to tank dimensions, reducing temperature unevenness.
A: Carbon steel jackets are suitable for mineral oil and neutral water media, but are not suitable for long-term contact with weakly acidic or weakly alkaline solutions. Stainless steel jackets have better durability in corrosive media, and the procurement cost increases accordingly. Operation and maintenance personnel should decide based on the medium composition, concentration, and temperature, referring to the material compatibility table, to avoid jacket corrosion perforation caused by improper material selection.
A: Multiple groups of heat exchangers should be evenly arranged according to tank dimensions and medium characteristics to avoid concentrated local heat load. For oils with higher viscosity, the number of heat exchangers can be appropriately increased and the power of a single group reduced. During arrangement, maintenance space and medium flow direction should also be considered to ensure full contact between the heat exchange surface and the medium.
A: Focus on checking whether the jacket surface has scaling, corrosion, or deformation, whether the wiring terminals are loose, and whether the insulation resistance is within the allowable range. If local temperature abnormalities are found, check whether the corresponding heat exchanger is disconnected or the medium flow is blocked. Regularly cleaning attachments on the jacket surface can maintain heat transfer efficiency.
The SLR-25 jacketed heat exchanger can be used for heating and cooling of water, oil, air, and neutral chemical solutions. In scenarios such as tank heat tracing, pipeline antifreeze, and reactor temperature control, selecting carbon steel or stainless steel jackets according to medium corrosiveness and arranging them reasonably according to tank dimensions helps extend the equipment service life.
