II. Understanding the ER Corrosion Probe

Spesifikasi

Probe Body: 316SS/ 316LSS/ DSS/ INCONEL is available

Temperature Rating: -200℃~260℃/260℃~450℃optional

Pressure Rating: Less than 45MPa

Mounting: Access System with Hollow Plug

It should be noted that a probe adapter is essential for connecting the collector and it needs to be ordered separately.

To prevent media leakage, several measures have been implemented in the probe design. The measuring element and the probe body are integrally welded, ensuring a secure connection. Furthermore, the probe rod is filled with a filler material that demonstrates high resistance to both heat and pressure. Lastly, the interface is effectively sealed using glass, further enhancing the probe’s leak-proof capabilities.

AKU AKU AKU. Prinsip Kerja Probe Korosi ER

Probe korosi resistensi listrik (ER) beroperasi berdasarkan prinsip resistensi listrik. Ini adalah metode yang banyak digunakan untuk mengukur korosi, terutama di lingkungan yang melibatkan sistem tekanan tinggi.

Teknik Resistansi Listrik

Dalam teknik resistensi listrik, laju korosi ditentukan dengan mengukur peningkatan resistansi listrik dari probe logam saat mengalami korosi. Saat logam berkarat, ia menjadi lebih tipis, yang pada gilirannya meningkatkan ketahanan listriknya. Perubahan resistensi ini dapat diukur dan digunakan untuk menghitung laju korosi.

The principle behind this is Ohm’s law, which states that the resistance (R) of a conductor is directly proportional to its length (L) and inversely proportional to its cross-sectional area (A). Hence, as the metal corrodes and its effective cross-sectional area decreases, its resistance increases.

Operation of the ER Corrosion Probe in a High-Pressure System

The ER Corrosion Probe, such as Model EMT-EP100, is designed to function effectively in high-pressure systems. The probe assembly comprises an extension rod with a sensing element and a threaded connecting seat, all of which are welded and sealed together to withstand high pressures.

The probe is installed into the high-pressure system via a hollow plug. The plug is secured using a probe nut and sealing ring, preventing any leakage under high pressure. The probe can be installed or retrieved during the process using a retrieval tool and service valve, without requiring a process shutdown.

The probe’s sensing element, which is in contact with the medium in the pressure system, undergoes corrosion over time. This corrosion leads to a change in the element’s electrical resistance, which can be measured and used to calculate the corrosion rate. The data collected by the probe can then be transmitted to a collector via a probe adapter.

IV. Benefits of Using the ER Corrosion Probe

Preventing Unnecessary Shutdowns

One of the key advantages of ER Corrosion Probes is their ability to prevent unnecessary shutdowns. Traditional corrosion monitoring methods often require system shutdown for inspection and maintenance, which can be costly and time-consuming. However, with ER Corrosion Probes, corrosion monitoring can be performed while the system is still operational. The data collected by these probes can inform decisions about when maintenance is truly necessary, thereby avoiding unnecessary shutdowns and optimizing system uptime.

Durability in Harsh Environments

Lastly, ER Corrosion Probes are known for their exceptional durability in harsh environments. The fully welded structure, the use of high-resistance filler in the probe rod, and the glass-sealed interface contribute to the probe’s ability to withstand high pressures and temperatures. This robust construction ensures that the probes can reliably function even in extreme conditions, providing consistently accurate corrosion data over their operational lifespan. This durability reduces the need for frequent replacements, contributing to cost savings and system longevity.

V. Applications of the ER Corrosion Probe

Various Industries

Di Industri minyak dan gas, these probes are used extensively in pipelines, refineries, and offshore platforms. They help monitor the corrosion rates of equipment exposed to corrosive substances, preventing unexpected failures and ensuring the integrity of the infrastructure.

Di chemical industry, ER Corrosion Probes are used in reactors, storage tanks, and pipelines to monitor the effects of various chemical reactions on the equipment. This helps in maintaining the operational safety and efficiency of the chemical processes.

Di power generation sector, terutama di pembangkit listrik tenaga nuklir dan termal, probe ini sangat penting untuk memantau laju korosi dalam boiler, penukar panas, dan sistem pendingin. Ini membantu menjaga efisiensi pembangkit listrik dan memperpanjang umur peralatan.

Di Industri pengolahan air, probe ini digunakan untuk memantau korosi dalam sistem yang terpapar berbagai kualitas air, membantu mempertahankan integritas sistem perawatan.

Skenario spesifik

A specific example of the ER Corrosion Probe’s beneficial application can be seen in offshore oil platforms. These platforms are exposed to harsh environmental conditions and corrosive seawater. Using ER Corrosion Probes, the corrosion rates of the structural components can be continuously monitored, enabling timely maintenance and preventing catastrophic failures.

In another instance, in a chemical plant dealing with highly corrosive substances, the ER Corrosion Probe helped identify an increased rate of corrosion in a reactor. This early detection allowed for immediate preventive actions, averting potential equipment failure and production loss.

VI. Kesimpulan

Singkatnya, probe korosi EMT ER, seperti model EMT-EP100, memainkan peran integral dalam berbagai industri dengan memberikan pemantauan korosi real-time dan akurat. Pendekatan proaktif untuk manajemen korosi ini secara signifikan meningkatkan efisiensi sistem, mencegah penutupan yang tidak perlu, dan memperpanjang umur peralatan. Desain yang kuat dari probe ini memastikan daya tahannya bahkan di lingkungan yang keras, lebih meningkatkan nilainya.

Pentingnya probe korosi ER melampaui manfaat langsungnya. Kemampuan untuk memantau dan mengelola korosi secara efektif sangat penting dalam menjaga keamanan dan keandalan berbagai sistem, terutama di industri seperti minyak dan gas, kimia, pembangkit listrik, dan pengolahan air. Probe ini tidak hanya membantu dalam mengurangi biaya perawatan tetapi juga berkontribusi secara signifikan untuk mencegah kegagalan tak terduga yang dapat memiliki dampak lingkungan dan ekonomi yang parah.

Saat kita melihat ke masa depan, peran probe korosi ER dalam pemantauan korosi diharapkan akan berkembang lebih jauh. Perkembangan dalam teknologi sensor dan analisis data dapat menyebabkan data korosi yang lebih akurat dan tepat waktu, memungkinkan pengambilan keputusan yang lebih baik dan pemeliharaan preventif. Selain itu, integrasi probe ini dengan teknologi digital, seperti Internet of Things (IoT) dan kecerdasan buatan (AI), dapat membuka kemungkinan baru untuk pemeliharaan prediktif dan optimasi sistem.
