(I) Distinct Advantages of KMT Pipeline
1) Magnetron Commander
KMT magnetron commander has a mode for keyboard operation which bestows it the feature of giving remote command. This eliminates the requirement of operator moving to-and-fro the commander. With ever keyboard press, a sound is prompted. The security and accuracy is extremely high as there is option of canceling the command in case the commander is moved in error.
KMT receiver is based on intelligent sampling zoom circuit. In addition, it also boast of integrating a special positioning algorithm in its software. This eliminates the requirement of manual adjustment to find the position. So, you get precise position without any error.
3) Self-diagnostic performance power
KMT pipeline crawler boasts of an integrated self-diagnostic function. Traditional PLC control is not present and hence the instrument has less weight and is more compact.
(II) Unit Structure & Overall Structure of KMT Pipeline Crawler
(III) The Key Technology of KMT Magnetic Positioning
1) Latest and newly introduced pipeline crawler magnetic position sensing system
people-oriented； environmental；zero accidents；zero injuries；zero pollution.
2) Characteristics and Effects
The anti-interference ability, stability and practicality of KMT crawler’s positioning sensor are exceptional.
KMT pipeline was used in the "Libya Elephant Oilfield Water-Injection Project". While the peak working hours, the crawler was successful in continuous detection of:
- Over 200 number of D609.6mm welds every day
- Overall 4,000 welded junctions, its failure rate was 0
This is exemplary to the outstanding stability of the KMT magnetic position sensing system of pipeline crawler.
(IV) Film Image Definition of KMT Pipeline Crawler
1) How To Improve Radiographic Definition
a) Variable frequency technology is responsible for improved definition, highly consonant, and for working independently from the battery voltage level.
b) "Differential" structure is implemented to make sure that crawling is done easily
2) Features of X-ray Pipeline Crawler
a) Short-voltage protection function
b) In case of circuit fail, crawler moves backward after 30 minutes
c) Power-off protection function
3) Technical Parameters
a) Display control unit (SD-9992D)
b) Display: 12.1 "LCD industrial touch screen; Brightness: 500cd / m2 highlighted; Resolution: 1024 × 768.
c) Function Display: There is a man-machine interface on which one can see various crawler's parameters such as crawling distance, crawling speed, overall pressure index, crawler’s tilt angle, the brightness of all primary as well as secondary sources; English version control software.
4. Video Storage: H.264 video compression format, built-in 300G hard drive.
5. Control Function: There is a wireless handheld controller and a touch screen keyboard which is suitable for operating every function in all possible states of crawler. For editing text, an analog keyboard is also provided.
6. Control Functions: control the crawler’s forward and backward, left and right turn, adjust lightness, camera control, one- key response to camera, lifting frame control, speed control, video recording, storing data recalls, text editing in live video.
7. Output port: AV output and multiple USB ports.
(V) Testing efficiency of KMT pipeline crawler
In Sep. 2014, in Mianyang city, Sichuan province, KMT pipeline crawler was used to test welds of natural gas-transporting pipeline of Guanghua company.
The said pipeline crawler was used since it was based on latest and high technology. This gave the machine exclusive benefits of precise test results, higher levels in detection, lesser cost of tests, particularity in case of long-distance delivery pipeline’s welding testing.
For detecting a 325 diameter pipeline, they used a traditional pipeline. Just 15 welds of the pipeline were detected in a complete one day. On the other hand, if KMT pipeline crawler was used, 30 welds of the pipeline were detected in the same duration. Hence, there was a double increase in their work efficiency. From cost point of view, KMT pipeline crawler uses only one film around one weld, saving 360mm film for customer for one weld.
(VI) Heat Treatment Of Kmt Portable X Ray Flaw Detector
When a X-Ray Generator is in operation, there is a creation of hundreds of thousands of volts. Along side, large amount of heat is generated when the electrons of X-Ray are bombard with the tungsten anode target surface. This means that cooling factor is a critical one. Altering the gap in iron core to alter the current in high-voltage transformer.
