Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe.

I. Introduction:
The cable fault tester manufacturer host is another masterpiece of the company. The technology has reached the international advanced level, breaking the monopoly of foreign companies in this field. The host adopts the highest international technology, and all high impedance fault waveforms are presented as simple low-voltage pulses. Waveform, easy to determine the distance to fault.
The cable fault tester manufacturers are used to detect high resistance leakage faults, flashover faults, low resistance grounding, and open circuit faults for various power cables.
Second, function and characteristic:
1. It can measure the high and low resistance faults of all cables below 35KV, and can adapt to a wide range of applications.
2. With user-friendly software and full Chinese menu. The key definition is simple and straightforward. The measurement method is simple and fast.
3. Detection of failure success rate, test accuracy and ease of testing better than any domestic testing equipment.
4 large touch LCD screen as a display terminal, the instrument has a powerful data processing capabilities and a friendly display interface.
5. With extremely safe sampling high voltage protection measures. Test equipment will not crash and damage in high-impact environment
6. No test blind spot.
7. Built-in power supply can test the open circuit and low resistance short circuit fault of the cable in no power supply environment.
Third, the main performance indicators:
1. Test methods: low pressure pulse, high pressure flashover, speed measurement.
2. Impact high pressure: less than 35KV power cable.
3. Data sampling rate: 80 MHz, 40 MHz, 20 MHz, 10 MHz.
4. Test distance: >30Km.
5. Reading resolution: 1m.
6. System test accuracy: less than 50cm.
7. The test cable pulse width is provided with "0.05", "0.1", "0.2", "0.5", "1", "2", and "8" microseconds.
8. With test waveform storage function: The waveforms that are tested in the field can be conveniently stored in the instrument in the specified order for observation at any time. A large number of field test waveforms can be stored.
9. The measured fault point waveform and the good-looking full-length open waveform can be simultaneously displayed on the screen to compare with the screen and superimpose and compare, and the fault distance can be automatically determined.
10. Built-in power supply: The instrument can work continuously for more than 3 hours after full charge, and it can also work with external AC power supply.
11. Working conditions: Temperature -10 °C ~ +45 °C, relative humidity 90%.
