Corrosion Probe Inc

Description

We are Corrosion Probe Inc and have produced a new resistance corrosion probe. Includes cartridge seal. One end of the cylindrical sealer is sealed. The other end has a connection structure for sealing the connection with the conveying pipeline. A rotating sleeve is worn on one end of the cylindrical sealer. The rotating sleeve is axially fixed and circumferentially rotatable is mounted on the cylindrical sealer and is in sealing cooperation with the cylindrical sealer. There is a pick-and-place screw on the rotating sleeve. The lower end of the pick-and-place screw rod is provided with a threaded section. It is for connection to corrosion coupons, and resistance probe threads.

When we use it, one end of the cylindrical sealer is connected to the delivery pipeline. Turn the pick and place the screw down until it is tight with the resistance probe. Rotating the rotary sleeve moves the pick-and-place screw up with the resistance probe. Then the resistance probe is taken out, and the whole process realizes the automatic pick and place of the resistance probe, and the operation is convenient.

In oilfield production and operation, the production operation is often affected by the corrosion of the inner wall of oil and gas pipelines. Therefore, we need regular corrosion monitoring of oil and gas pipelines. In this way, we can grasp the corrosion situation of the pipeline. In order to optimize the anti-corrosion measures. Ensure the safe operation of pipelines.

Working Principle:

Resistance probe type corrosion online monitoring system is use electromagnetic resistance corrosion monitoring technology. The signal collected by the field probe is transmitted to the industrial processor through the transmitter and the signal cable. This enables fast and accurate determination of corrosion data in production plants. There are also reads, network transfers, feedback, and data sharing. Corrosion laws are studied by analyzing corrosion monitoring data. Then the purpose of corrosion monitoring to corrosion monitoring can be achieved.

The resistance probe method is to measure the corrosion rate by measuring the change in the resistance value of the metal sensing element exposed to the medium in the process of corrosion. Corrosion of the surface of metal elements results in a reduction of the metal cross-section. This in turn increases the resistance accordingly. The change in resistance is specifically reflected in the change in current. There is a certain functional relationship between current change and metal corrosion. Resistance probe corrosion monitoring uses the relationship between current change and metal loss to determine metal corrosion rates.

Inductance probes are placed on metal/alloy sensitive elements by measuring. The corrosion rate is measured by the change in impedance of the surrounding coil due to corrosion of the sensitive element. Because of its high magnetic permeability. So the sensitive element greatly strengthens the magnetic field strength around the coil. It in turn significantly increases the line country’s inductive reactance. The inductive reactance method combines the fast response of the linear polarization method with the widely applicable advantages of the resistance probe method. This makes it possible to quickly and accurately measure corrosion rates in any corrosive environment.

The probe is installed on the processing pipeline, and the analog signal related to the corrosion rate is collected by the data collector. After amplification, it is converted into a digital signal. And sent to the monitoring room computer. After the data reaches the computer, it is processed, displayed, and a database is established. Then we monitor it online in real-time through multiple points. This obtains the corrosion conditions at various points in the production process.

Background technique:

Online corrosion monitoring technology is a specialized technology developed in China in the past ten years. It is mainly aimed at continuously monitoring the corrosion rate of steel pipes and equipment under normal operation of the medium. And it can evaluate the corrosion inhibitor effect. This is a reliable and effective method for controlling corrosion and assessing safety within steel piping and equipment.

The electro-corrosion shell is the original measurement, and it also easily has damage. If the pressure is too high or the corrosion is too severe, it will cause damage to the measuring element. Two immediate manifestations of this damage are perforation or breakage of the measuring element. The consequence of this is pressure into the infill wall inside the corrosion probe. This subjects the solder joint of the needle to the threaded sleeve to high pressure. Leaks can then occur and there is a certain risk.

Electrocorrosion shells not only have the above-mentioned technical problems. At the same time, it also has the problem that the electro-corrosion shell is often in the pipeline when the steel pipeline needs to be cleaned. This can hinder the cleaning of the pipes. And the cleaning solution is easy to damage the electro-corrosion shell.

Therefore, it is necessary to design a working state that can adapt to high pressure. At the same time, it does not affect the technical scheme of the high-pressure corrosion resistance probe for pipeline cleaning.

Technical implementation elements:

We offer a high-voltage corrosion resistance probe. It can solve the problems in the existing technology. For example, when cleaning pipes, the conventional electro-corrosion shells tend to hinder. Also, conventional corrosion probes cannot for high pressure. Especially in the special working state of the early natural gas well testing process, the middle technical problems.

In order to solve the above-mentioned technical problems, the beneficial effects of a probe capable of withstanding high pressure and being convenient for pipeline cleaning are achieved.

This product is realized through the following technical solutions:

It includes a casing, and two ends of the casing are respectively connected with a mounting sleeve and a threaded sleeve. The mounting sleeve, the housing, and the threaded sleeve form a cavity.  The electrode holder is provided with an electrode sheet for detecting the corrosion rate in the pipeline. The other end of the threaded sleeve has a connection to a plug body with a needle. The resistance probe also includes a pressure-resistant sealing device.  It is respectively connected to the inner wall of the shell and the inner wall of the threaded sleeve.

In order to better realize the utility model, further. The mounting sleeve mainly includes a connecting part and a mounting part that has a connection to the shell. The connecting portion and the mounting portion are integrally formed. A cavity is formed in the connection part, the shell, and the threaded sleeve.

Principle:

The device is a high-voltage corrosion resistance probe. It is mainly to monitor the corrosion rate in the pipeline. At the same time, it is monitored by measuring elements. This transmits the monitored signal through the conducting needle to the needle site. Because the device is in the oil and gas pipeline system, it is usually necessary to clean the pipeline. Our commonly used measuring elements are electro-corrosion shells. The electro-corrosion shell needs to pass through the pipeline and extend into the pipeline. This can achieve the purpose of monitoring. The electro corrosion shell easily has damag during cleaning.

This increases the cost. It also brings greater inconvenience to cleaning, in order to improve the above shortcomings. Therefore, in this device, the measuring element is configured as an electrode pad. Electrode pads need to pass through the pipe. And fit on the inner wall of the pipe. It does not need to protrude into the tube. This thus solves the inconvenience brought about in the previous cleaning process. Because it uses electrodes. Therefore, monitoring is more sensitive. This makes it more practical to monitor the corrosion rate within the tube.

Corrosion Probe

Oil and gas pipeline system. The working pressure is usually within 10MPa. However, the working pressure needs to reach 63MPa during the early gas well testing. In order to adapt to ultra-high pressure conditions, the device is provided with a sealing device in the cavity. The main function of the sealing device here is to seal and resist pressure. When the corrosion is too severe, air pressure enters the cavity. High-temperature ceramics on the sealing device can play a role in compression. The sealing screw acts as a block. This is to prevent high-pressure damage to the needle.

An ultra-high pressure probe designed by us. It can withstand the pressure of up to 63Mpa. Therefore, the use of the device is stronger.
