I would like to ask about instrument selection in coastal areas
Thread Content
For projects in Indonesia, where there is heavy rainfall, and where protection against salt spray corrosion is required, does this mean that instruments, whether indoor or outdoor, all need to be designed to resist salt spray corrosion? How should this be specified in the selection process? Is it necessary for outdoor instruments to have an IP66 rating? What is the maximum protection level that explosion-proof instruments can achieve? Is it not possible to use such ratings?
In coastal areas, especially in humid and rainy environments like Indonesia, it is indeed necessary to give thorough consideration to the resistance of instruments to salt spray corrosion. For instruments, whether indoor or outdoor, it is recommended to choose products with resistance to salt spray corrosion. For outdoor instruments, an IP66 rating is essential to ensure their water and dust resistance in harsh weather conditions. The protection rating of explosion-proof instruments can usually reach IP67 or higher, but the specific choice depends on the actual environment and safety requirements. When selecting a product, it is possible to specify in the technical specifications that the instrument should have resistance to salt spray corrosion, along with the required protection level, such as IP66 or higher. At the same time, ensure that explosion-proof instruments meet relevant safety standards. .
I think the water and dust resistance of the instruments is an important factor in selection, and installation cannot be ignored either.
I have a question: the IP66 rating is meant to prevent dust and water from entering, right? Is it unnecessary to use a protection box with both IP65 and IP66 ratings? It would be better to just choose an IP66-rated instrument. How is salt spray resistance taken into account when selecting instruments? For example, the material of the instrument’s enclosure is chosen to be 316, and the wiring box for temperature instruments is also made of 316. As for protective tubes, they are generally selected based on the properties of the medium used; is it necessary for them to be made of 316 as well? How should the material for valves be chosen? Is it too costly to use 316 all the time?
Select the appropriate product based on the on-site conditions, and in accordance with the owner’s budget: D
You can request C5-I or C5-M; the standard number is in the upper left corner. You can refer to it
If you want something reliable and long-lasting, it’s better to add an instrument panel or a rain cover as needed
For high-value instruments, install protective boxes; for those of lower value, focus on the material used
