What Is Corrosion Probe Installation?

Corrosion probe installation is the online fitting of EMT corrosion probes into live pipelines, so plants track wall loss without a shutdown. We mount each probe through a hollow plug and a service valve, and the probe reaches the process stream under full pressure. Refineries, offshore platforms, and chemical plants use this method on oil, gas, water, and multiphase lines. The probe element matches your pipe alloy, such as 316L, duplex stainless steel, or INCONEL, so the reading reflects your true corrosion rate. You avoid hot-tapping and line drain during the work. EMT supplies both ER and LPR probes for the same access system. The retrievable design lets you pull a worn probe and fit a new one under flow. The result is continuous, real-time corrosion data from a safely installed sensor on a running line. Our engineers advise the best nozzle position for accurate, representative monitoring of your process.

EMT lists these specs for each probe and tailors probe length, element material, and process interface to your exact line. Pick the body alloy to match your pipe. Choose ER for long-term metal-loss trend or LPR for instant rate. The hollow-plug mount keeps every option online and retrievable. Pressure, temperature, and hazardous-area ratings decide the right seal and housing. Our engineers confirm the model code before build. We also supply the separate probe adapter that links the probe to your collector. Share your line size, medium, and target rate with us. We then return a matched, ready-to-fit part with the correct seal, cable, and certification for your site. Most plants fit probes at pump suction, headers, or chemical injection points for early warning. We label each unit with its model code and calibration date for full traceability. Good placement catches corrosion before it threatens wall strength or causes a leak.

How Does Corrosion Probe  Work?

Corrosion probe installation starts at the pipe nozzle. First, you weld or bolt the flange base to the nozzle. Next, you screw the probe into the hollow plug with a probe nut and a sealing ring. Then a retrieval tool pushes the assembly through the service valve while the line stays live. The probe nut and seal hold pressure at the interface. Once seated, the probe element meets the process fluid directly. For ER probes, corrosion thins the element and changes the AC signal we measure. For LPR probes, the circuit reads the instant corrosion rate. You retrieve or swap the probe the same way, with no shutdown and no hot-tap. The method needs only standard access fittings and a trained field technician on site. After seating, you link the collector by cable or wireless and log data with no flow interruption. We log each step for your site records.

Why Choose Corrosion Probe Installation?

EMT probes give clear, practical advantages that protect plant integrity, uptime, and budget:

• Corrosion probe installation runs fully online, so you avoid shutdown and cut costly downtime on live, running lines, every cycle.
• A material-matched element gives a true corrosion rate that matches your exact pipe alloy, medium, and real service you run.
• A welded, glass-sealed body blocks leaks at 45 MPa and resists harsh, high-pressure, corrosive field duty, with no weep.
• IP66 housing with Ex d IIC T4 Gb rating suits explosive, hazardous-area sites without extra enclosures on site.
• The retrievable, standard hollow-plug design lets you swap probes fast, with no cutting, welding, or hot-tap work, at any time.

FAQ

Q: How is EMT corrosion probe installation done without stopping the line?

A: The probe sits in a hollow plug. A retrieval tool pushes the plug through a service valve while the line runs. The probe nut and sealing ring hold pressure, so no shutdown or hot-tap is needed.

Q: Which probe material should I choose?

A: Match the probe element to your pipe alloy. We offer 316L, duplex stainless steel, and INCONEL. Matching ensures the reading reflects your actual equipment corrosion rate.

Q: What pressure and temperature can the probe handle?

A: Standard probes handle up to 45 MPa and -200 to 260 C. We can upgrade the temperature rating to 450 C for high-heat service.

Q: Do I need a separate adapter for data collection?

A: Yes. The probe adapter links the probe to the collector and must be ordered separately. The collector can mount on the probe or be placed remotely via cable.

Q: Is EMT a certified manufacturer?

A: EMT holds ISO 9001 and ISO 14001 certifications and has 20+ years in pipeline integrity, exporting to over 20 countries.
