Description
1. Introduction
The EMT Pig Signal Detector is an advanced intrusive bidirectional triggering pig detector specifically designed to monitor pig passage through pipelines. This detector can be equipped with multiple display options, including B, C, D, and CD displays, each providing distinct indications and actions when a pig passes through the pipeline.
- B Display: The indication flag shifts from horizontal to vertical.
- C Display: The indication flag shifts from horizontal to vertical, and the SPDT or DPDT switch activates and remains active.
- D Display: A digital time display begins counting and records the exact trigger time; the SPDT or DPDT switch activates and remains active until a factory-set time, after which the display returns to standby.
- CD Display: The indication flag shifts from horizontal to vertical. The SPDT or DPDT switch activates when the trigger deflects a certain angle and resets after the trigger resets; the digital time display functions similarly to the D display.
The SN2-TQZ detector connects via a 2″ flange. Models ending in REUV denote an upper ball valve handled under pressure, mounted above the foundation. Models ending in REDV denote a lower ball valve handled under pressure, mounted below the foundation.
2. Installation
Prior to installing the SN2-TQZ pig detector, ensure the pipeline is prepared with a flange that matches the installation specifications of the detector. The flange should adhere to ANSI B 16.5 standards or customized standards, with a space of 150mm from the flange top face to the internal pipe wall or as per custom measurements.
- Preparation: Place a compatible sealing gasket (3.2mm for RF flanges) between the two flanges, ensuring the indicator’s trigger action aligns correctly with the pipeline.
- Insertion: Insert the trigger end into the pipeline and secure the flange seat to the pipeline interface using screws.
- Display Adjustment:
- For B, C, and CD displays: Loosen the four nuts under the display’s square flange, rotate the flag display to the desired position, and retighten the nuts.
- For D displays: Unscrew the knurled nut under the display, adjust its direction, and retighten.
3. Maintenance
Regular maintenance ensures the effective operation of the SN2-TQZ pig detector.
- Seal Replacement: If leakage occurs at the flange seat, the seal is likely damaged and needs replacing. External seals can be replaced directly, while internal seals should be replaced by the manufacturer.
- Flange Seat Removal: For non-retrievable pig detectors, ensure the pipeline or system is depressurized before removing the flange seat.
- Core Removal Under Pressure: Special tools are required for removing the core of retrievable pig detectors under pressure.
- For SN2-TQZ-x-REDV models: Use a special long bolt, standard nut, and common spanner.
- For SN2-TQZ-x-REUV models: Special tools are necessary for safe removal under pressure.
By adhering to these guidelines, the EMT SN2-TQZ pig signal detector can be effectively installed, adjusted, and maintained, ensuring reliable pig passage monitoring and system integrity.
