2. Description of Corrosion Probes and Coupons
The EMT-EP100 probe features a fully welded structure, making it highly suitable for harsh environments. Its robust design includes:
- Extension Rod with Sensing Element. The probe assembly consists of an extension rod that houses a sensing element, allowing for precise corrosion measurement.
- Threaded Connecting Seat. This facilitates secure installation and retrieval of the probe.
- Welded and Sealed Components. You weld and seal each part of the probe assembly to ensure durability. You further protect the interface end with high-temperature glass sintering, which enhances its resistance to extreme conditions.
- Protective Cap. The probe sensor can be equipped with a protective cap to safeguard it during installation and operation.
1) Installation and Retrieval
Key features include:
- Hollow Plug Connection. The probe is installed into a hollow plug using a probe nut and sealing ring, ensuring a secure fit.
- Retrieval Tool and Service Valve. The probe-plug assembly can be efficiently installed or retrieved using a dedicated retrieval tool and service valve, facilitating maintenance while keeping operations running smoothly.
2) Specifications
Matériels
You can construct the probe body from various materials, including 316 stainless steel, 316L stainless steel, duplex stainless steel (DSS), and INCONEL. This variety ensures compatibility with different media.
Temperature Rating
The probe operates effectively within a temperature range of -200℃ to 260℃, with an optional range extending from 260℃ to 450℃.
Pressure Rating
This probe handles pressures less than 45 MPa, making it suitable for high-pressure applications.
Prévention des fuites
To prevent media leakage, the design integrates the measuring element with the probe body through welding. The probe rod contains a heat and pressure-resistant filler, and the interface is sealed with glass. This combination ensures reliable performance in challenging environments.
