CE-IT Buried Pipeline Insulating Flange Tester
Used to measure the insulation performance of insulating flanges with cathodic protection, it can directly display the final result of the measured insulating joint, such as short circuit, short circuit, or good. On-site testing requires no calibration or operation, and it can determine whether the insulating joint has failed within 30 seconds.

Introduction to the CE/IT Buried Pipeline Insulating Flange Tester
The CE-IT Buried Pipeline Insulating Flange (Insulating Joint) Tester from Tinker & Rasor Company in the United States was developed by the American Tinker & Rasor Company (referred to as TR Company) for quickly testing the insulation performance of insulating flanges and insulating joints on buried pipelines. The CE-IT Underground Pipeline Insulator Performance Tester is a fully automatic, highly sensitive electronic device used to test the effectiveness of buried pipeline insulators, and it can also be used to determine the isolation status of road crossing casings.
The Model CE-IT Insulator Tester is fully automatic and highly sensitive electronic instrument designed to test the effectiveness of buried pipeline insulators. The CE-IT can also be used to determine isolation condition of pipelines in road crossing casings.
During testing, the internal circuit of the CE-IT Buried Pipeline Insulating Joint Performance Tester can automatically adapt to the voltage polarity present on the underground pipeline system. The entire testing process is completed within 30 seconds, and the test results are displayed as readings on the LCD screen, with an audio signal to alert the operator when the test is complete. The CE-IT Buried Pipeline Insulator Performance Tester from the American Tinker & Rasor Company has been factory-calibrated and can be used directly without on-site adjustments. The RF-IT Surface Pipeline Insulating Joint Tester from the American Tinker & Rasor Company has been applied to the effectiveness testing of insulating flanges and insulating joints both domestically and internationally, becoming one of the equipment for ECDA effectiveness assessment of buried pipelines. The RF-IT Above-ground Pipeline Insulating Joint Tester, when used in conjunction with the CE-IT Buried Pipeline Insulating Flange (Insulating Joint) Tester, can solve the insulation performance testing of all flanges and joints.

The circuit of the CE-IT Underground Insulating Joint Tester can automatically adjust and adapt to the voltage polarity present on the pipeline being tested, and the test results are displayed in English on the LCD screen.
"GOOD": When the CE-IT detects that the electrical load on either side of the pipeline insulator does not leak from one side to the other, the LCD screen displays "GOOD"; this means that an electrical load can be created, so it is confident that the insulator is good.
"BAD/SHORT": When the CE-IT detects that the electrical load on either side of the pipeline insulator leaks from one side to the other, the LCD screen displays "BAD/SHORT"; this means that an electrical load cannot be created, so it is confident that the insulator is ineffective.
"BAD/OPEN": When the CE-IT cannot create an electrical load on one or both sides of the insulator, the LCD screen displays "BAD/OPEN"; this result indicates that the wires on one or both sides of the pipeline insulator being tested are disconnected.
Technical Principles of the CE-IT Underground Insulating Flange Tester
The true impedance value of a buried insulator depends on many factors, such as the environment at its location. In environments with very low impedance, the impedance measurement for an insulation failure point should be below 0.5 ohms. Therefore, for the inspection of insulation failure points in buried pipelines, current leakage testing is better than built-in impedance testing. For this reason, the TR-CE-IT Buried Pipeline Insulator Performance Tester considers the electrical performance of the failure point itself, rather than its built-in impedance. Generally, the following situations may occur during insulator testing:
· In practice, different ground voltage readings can prove to be on opposite sides of the insulator; when the difference in ground voltage across the insulator is small or of opposite polarity, it indicates that it comes from the opposite side of the protected section of the pipeline.
· The current leakage allowed to flow at the contact point is 25% or lower;
· The voltage drop across the insulator is relatively significant (while the voltage drop across an ineffective or short-circuited insulator is negligible, typically 10 millivolts or lower);
The CE-IT Buried Pipeline Insulator Performance Tester uses the above three criteria to determine the condition of the insulator and the test path (for example, from the test post to both sides of the insulator): open circuit, short circuit, or good.
