3. Design and Construction

Material Selection and Durability:

The EMT-EP100 ER Corrosion Probe is constructed from a selection of high-grade materials known for their strength and resistance to corrosion. The use of 316 SS and 316LSS stainless steels provides excellent resistance against a wide range of chemicals and corrosive environments. Duplex Stainless Steel (DSS) offers even higher strength and toughness, which makes it ideal for demanding applications where mechanical and corrosion resistance is critical. Additionally, the inclusion of INCONEL, an alloy well-suited for extreme environments, enhances the probe’s capability to withstand high temperatures and corrosive pressures, making the EMT-EP100 exceptionally robust in hostile operational conditions.

Structural Integrity and Welding:

The probe’s fully welded structure is a key feature in its design, contributing significantly to its overall integrity and durability. This welding ensures that all components of the probe are securely joined, eliminating any potential weak spots that could lead to structural failures or media leakage. The hermetic sealing of each joint further reinforces this effect, creating a solid, unitary construction that can withstand the rigors of operational stresses without compromise.

Probe Assembly Components:

The probe assembly is a meticulously design for optimal performance and reliability. It includes:

• Extension Rod. This component houses the sensitive sensing element and is crucial for the transmission of corrosion data from the point of measurement to the monitoring system. The rod is designed to ensure that the sensor remains correctly positioned within the pipeline, maximizing its exposure to the internal environment for accurate corrosion monitoring.
• Threaded Connecting Seat. This feature of the probe facilitates a secure and reliable connection to the pipeline system. The threads are precision-engineered to match industry-standard specifications, ensuring a tight fit that prevents any movement that could affect measurement accuracy or lead to wear and tear over time.
• High-Temperature Glass Sintering. At the interface end of the probe, high-temperature glass sintering works to seal and protect the internal components. This method of sealing is chosen for its superior durability and reliability under high temperature conditions, effectively insulating the internal elements from external environmental factors that could degrade the probe’s performance.

4. Functionality and Installation

Functionality:

The EMT-EP100 ER Corrosion Probe has a protective cap to shield the sensing element from damage and contamination, ensuring reliable corrosion monitoring. It seamlessly integrates with monitoring systems to provide real-time, accurate corrosion data, essential for pipeline integrity assessments.

Installation:

Installation of the EMT-EP100 is straightforward and designed to minimize system downtime. The probe attaches to a hollow plug using a probe nut and sealing ring, ensuring a secure, leak-proof connection. It is installed or retrieved using a retrieval tool and service valve, allowing operations to continue without the need for process shutdowns. This retrievable design facilitates easy maintenance, recalibration, or adjustment, enhancing system adaptability and operational efficiency without significant interruptions.
