China Pig Signaller EMT

Description1. OverviewThe China Pig Signaller EMT is a piece of the necessary equipment in the process of ball passing and descaling in long-distance pipelines. It can accurately show whether the pig has passed a predetermined location. At the same time, it can assist the smooth completion of the pigging and cleaning.At present, the China Pig Signaller EMT used at home and abroad can basically meet the requirements of pigging and cleaning. But it is more troublesome for us to maintain and repair it. Most workers need to depressurize the line to stop production. All economic losses are immeasurable.Because of the above reasons. The company has also developed and developed a through-ball indicator that can be disassembled under pressure without the need for pipeline pressure relief and shutdown. Its body parts are made of stainless steel. It is acid and alkali resistant and corrosion-resistant. This through-ball indicator is in the form of mechanical contact. It is responsive and reliable. And it can be positioned and timed on the pipeline through the mechanical structure. And it can transmit the passing situation of pig objects in the pipeline. It has the characteristics of simple structure, explosion-proof and intuitive indication. And it is reliable and can be disassembled under pressure and has many other advantages. Before installing and using this indicator. Please read the manual carefully.2. Technical characteristics1. Applicable pressure range: P ≤ 10Mpa; 2. Applicable temperature range: -20℃～80℃; 3.

Equipment structureChina Pig Signaller EMT is mainly composed of the following components. 1. Base – Welded on the pipeline. (20#); 2. Mounting flange – connect the ball valve and the base. (Stainless steel); 3. Ball valve – It is the main part of the dismantling device under pressure. (Stainless steel); 4. The main body of the machine – the main part of the demolition function with pressure. (Stainless steel); 5. Air release valve – open to relieve pressure twice. (Stainless steel); 6. Positioning screw-limit 7. Connecting ring – used to connect the mechanical body and the watch head 8. Meter – The explosion-proof case is equipped with a field indicator flag. There are also digital display and remote signal terminals. 9. Safety cardboard – safety self-locking function,4. Installation and use1. Installation of China Pig Signaller EMT base Begin by removing the base from the ball pass indicator. The pipeline is then opened vertically above. Opening size Φ56. Insert the base into the solder. Note: The insertion depth of the base is based on the bottom of the base being flush with the inner diameter of the pipeline. 2. On-site installation of the ball indicator After the welding is completed, install it according to the structural form. Note that the direction of the bleed valve is consistent with the direction of the pipeline.5. The adjustment of the clock control head1. Technical characteristics of clock control headThe clock head of this indicator is explosion-proof. All it can be reliably used in the explosive mixtures formed by flammable gases such as petroleum and petrochemicals, which belong to Class II, Class B, Group T4 and below. The clock control meter is powered by 4 5# batteries 6V. It is based on a microprocessor chip. And it automatically remembers the pass time. Low-power working state. 4 batteries can be used for 1 to 2 years. The digital display provides time information to the operator.2. Operation method of clock control headThe clock control table has four LED digital light-emitting diodes. There are also two LEDs and three buttons. Four digital tubes are used to indicate the current time or the pig passing time. Two light-emitting diodes are used to indicate the pass-through condition. Three buttons are used to start the instrument. Check the time, set the time and reset the function.Preparation before passing the ball: Press the yellow button to activate the indicator. Such as digital display time and accompanied by light-emitting diode light. This time is the pass time and must be cleared.Method: Press the red key and the green key at the same time. Let go until the digital tube displays “00.00”. The indicator completes the clearing operation. The memory of the previous pass has been eliminated. At this point we press the yellow button. The nixie tube displays four horizontal bars. Then you can proceed to the next step.Setting time:The instrument will not be used for a long time. If there is a time difference. Then we can readjust the time.Time adjustment: After pressing the start button. Press the “red button” for about 3 seconds. The “hour” display code of the digital tube is flashing. This indicates that an hourly adjustment is possible. Press the “green key” and “yellow key” to add or subtract the “hour” number. After the adjustment is correct, press the “red key” to confirm. At the same time, the “minute” display code flashes. This indicates that the time “minutes” can be adjusted. Press the green key and the yellow key to add or subtract the “minute” number. After the adjustment is correct, press the “red key” to confirm. The numbers stop flashing. Displays the correct time. Then complete the time adjustment. Instantaneous display of the passing ball: when the pigging ball passes, the ball activates the transmission rod of the indicator. After the meter head senses, the on-site indicator flag is activated. At the same time it sends out a remote switch signal. The digital tube displays the current time. At this time, it is accompanied by flashing, and then goes out after 10 seconds. and remember this through time. The passing ball indicator has the function of clock display and memory display of the instant time of passing the ball.The viewing process is as follows:Press the “yellow key”. If the middle light-emitting tube is on, then the digital tube displays the time. This represents the time for the pigs to pass through. If the nixie tube displays four horizontal bars. This indicates that the pigging ball did not pass. (After pressing the “yellow key” to start) press the “green key”, the digital tube displays the current Beijing time. 5.2.1 and 5.2.2 operations can be switched at will. Note: This product is a low-power explosion-proof instrument. Under normal circumstances, the instrument is generally in the sleep state. That is, the digital tube does not display. This is only displayed for a few seconds to more than ten seconds when passing the ball, viewing, and adjusting the time.3. Lead method of external remote signalThe inside of the clock control meter provides lead terminals for external remote signals. Its type is a single pole double set (SPDT) travel switch. The capacity is AC380 DC220 5A. Remove the rear end cap of the clock control head. Lead the wire through the lower connector. It is connected with the remote signal terminal (SPDT) terminal. When the pig passes through, an instantaneous switch signal can be transmitted.6. With pressure disassembly method:1. Disassembly steps under pressure (only used when replacing O-rings) 2. Installation steps under pressure: When installing, first screw in the safety card and the core. When the safety card plate ⑽ moves to the upper limit of the notch, install and tighten the air release valve. Fully open the ball valve. Continue screwing in the core. until the core is fully screwed in. Adjust the core body notch so that it is aligned with the safety card notch. Then install the set screws and tighten. Finally, connect the header and the installation is complete.Rand                                               EMT PiggingPlug Type                                        Bidirectional or UnidirectionalInsert Depth                                    21 mmFlange Material                              Carbon Steel or Stainless SteelFlange Class                                   300#Operating Temperature                 -20 ℃ ~ 120 ℃FeaturesDesign Pressure:2500 PSI (17.2 MPa)6000 PSI (41.3 MPa)Design Temperature: -4℉ ~ 302℉ (-20℃ ~ 150℃) -15℉ ~ 400℉ (-26℃ ~ 204℃)Easy to use and cheap: China Pig Signaller EMT is simple to use, you can search “EMT Retrieval Tool” on YouTube.
