During on-site troubleshooting, procurement personnel often find that after continuous operation, heat exchangers exhibit issues such as increased pressure drop on the medium side, interface leakage, or material corrosion. Most of these problems are related to the failure to provide complete engineering parameters during the selection stage. The SLR-36 jacketed heat exchanger is designed based on the heating and cooling requirements of water, oil, air, and neutral chemical solutions. The following outlines the key procurement and usage points from an engineering parameter perspective.
The equipment can handle water, oil, air, and neutral chemical solutions. The materials of the jacket and heat exchange tubes are selected based on the corrosiveness of the medium. During procurement, the medium name, concentration, and operating temperature must be specified. For neutral chemical solutions, the chloride ion content should be confirmed to avoid selecting metal materials prone to stress corrosion.
The design operating temperature range and pressure rating are determined according to the working conditions. Before procurement, the maximum operating temperature, minimum ambient temperature, and system pressure must be provided. When the medium temperature approaches the allowable upper limit of the material, a margin should be reserved, and the impact of thermal expansion on interface sealing should be considered.
Flow parameters directly affect the heat exchange area and pressure drop. The purchaser should provide the medium flow rate, allowable pressure drop, and interface type (flange, threaded, or welded). The interface size must match the on-site piping to avoid additional resistance or leakage points caused by diameter reduction.
The equipment requires reserved maintenance space to facilitate jacket removal and tube bundle cleaning. For oil media, scaling should be checked regularly; for water media, attention should be paid to scale and microbial corrosion. The installation location should be away from vibration sources, and the interface orientation should be convenient for operation.
When requesting a quote from the supplier, it is recommended to provide the medium name, operating temperature, flow rate, interface specifications, and material requirements. The supplier will confirm the model and configuration based on this information to avoid selection deviations caused by incomplete parameters.
