Short section is a kind of fittings commonly used in industrial pipeline connection. There are common thread nipples, which are divided into two heads, outer silk, single head outer silk, flat head and outer silk, and some short joints with flanges.
The short section is divided into tubing short section and casing short section. The flanging short section in the pipe fittings is popular with the flange. The flange is set in the flanges, then the tail and the steel pipe are welded. At this time, the flange can be moved. As long as the flange is connected to the flange at any time, the flange can be connected.

1, according to the actual lighting needs of the work site of the explosion-proof road lamp, determine the lamp and ballast installation location and method, and then press the lamp to the ballast contact point distance and ballast to the 220V power contact point to prepare the appropriate length Three-core cable (no more than 2 meters available with the lamp cable).
2. Close the ballast box cover and tighten the fastening bolts. Finally, connect the other end of the three-core cable to the 220V power supply according to the explosion-proof requirements.
3. When the distance between the explosion-proof road lamp and the ballast contact exceeds 2 meters, the three-core cable needs to be replaced. That is, use an Allen wrench to unscrew the six hexagonal bolts of the lamp housing. After the lamp body is pulled out, remove the three-core cable that comes with the lamp, and then connect the prepared three-core cable according to the original connection method.
4. Introduce one end of the prepared three-core power cable through the input device of the ballast input port, introduce the ballast cavity, and then connect the L line (FireWire), N line (neutral line), and ground line to the ballast. On the terminals of terminals 1, 2, and 3, and tighten the compression nut.
5. Use a socket wrench to unscrew the fastening bolts on the ballast cover and remove the cover. Introduce one end of the three-core cable of the lamp into the ballast cavity through the ballast output device and put the red wire. The black line (or blue line) and the yellow-green line are connected to the ballast's terminals 4, 5, and 6 respectively, and then the compression nut is tightened.
6. When replacing the bulb, first cut off the power of the explosion-proof road lamp , check whether the hanging chain is hanging, then use the Allen wrench to unscrew the six hexagon socket bolts on the lamp shell, and carefully pull down the lamp body part to make the lamp body The lamp caps are separated and the old bulb is unscrewed and replaced with a new bulb.
The tubing short section is a short tubing. Compared with the tubing, it is only of different lengths and the others are the same. The lengths are: 0.25m, 0.5m, 1M, 1.5m, etc., which are used to match the downhole string.
