文远环保（13280671957）PE农田灌溉管焊接,PE农灌管连接,PE灌溉管怎么焊
第一步：准备
将pe热熔对接焊机准备好，包括液压站、铣刀、加热板等相关电源，并将对接架平稳放置；第二步：放置
将需要焊接的两段pe管放置于对接架中，连接处置于对接架四夹具的中间。
第三步：固定
合上对接架的上下支架，并用螺栓将pe管固定。
第四步：铣削
将铣刀从提篮中拿出，放置于两pe管中间，推动液压站的操纵杆，将两pe管与铣刀接触，直至两连接平面铣好，铣出连续的长带状碎屑。
第五步：对中
因为铣削过程中可能会对固定的管材造成偏移，所以一定要再次对中、调整错边量，当然也要注意不要污染端口，否则必须再次进行切削。
第六步：加热
将铣刀放回至提篮，并将加热板从提篮中取出放入两pe管中间，进行加热，待两管开始翻边并达到要求之后，放回加热板。
第七步：焊接
将热板取出后，立即按要求的压力，迅速合拢待焊接PE端口。
第八步：冷却
对接完成后，有一个保压冷却的时间，最后冷却时间到了，焊口温度和环境温度一致，才可以卸压至0并拆下所焊管材，本次焊接结束。
镀锌方管焊接用2.5mm焊条就可以，不过对接难点，搭接或者角接容易点，另外有镀锌层肯定焊缝成型不太好，因为镀锌层的锌金属是一种低熔点技术，在焊接时锌层会沸腾爆炸，使焊缝成型变差；另外因氧化锌有毒，焊接时做好抽风排烟以免影响身体健康。
1、管道和接头的表面要保证平稳、清洁、无油。
2、将管道插入管件试装，对好方向、角度，并做好记号。
3、把试装过的熔接管道和管件，插入自调式热熔焊机对应型号的加热模具中，接通机器电源并等待片刻，当绿灯闪烁说明已经达到熔接温度，可以进行熔接工作了。
4、把管道平稳而均匀地推入管件接口中。
5、在管道接头插入管件接口之后的几秒钟之内，必须把管道与管件接头调节到标记好的位置。
6、经过几分钟时间的冷却，熔接接头就可以达到标准强度，完成熔接工作。

Step 1: prepare
The PE hot melt butt welding machine is ready, including the hydraulic station, milling cutter, heating plate and other related power supply, and the stable placement;
The second step: place
The two section will need to be placed on the welding to butt the rack in the middle connecting frame four disposed docking fixture.
The third step: fixed
On the shelf on the docking bracket, and the bolt will be fixed to.
The fourth step: Milling
Remove the cutter from the basket, placed in two to promote the middle hydraulic lever, two PE and the cutter contact, until the two connected plane milling, milling a long continuous strip of debris.
The fifth step: Centering
Because the milling process may result in a fixed pipe offset, so be sure to adjust the wrong side of the amount, of course, we should also pay attention not to pollute the port, or must be re cutting.
The sixth step: heating
The milling cutter is put back to the basket, and the heating plate in the two to the middle, removed from the basket for heating, after two pipe flanging and meet the requirements of the heating plate, put back.
The seventh step: Welding
The hot plate removed immediately, according to the requirements of the pressure of rapid closure for welding PE port.
The eighth step: cooling
After the completion of the docking, there is a pressure to maintain the cooling time, the final cooling time, the welding temperature and the ambient temperature in order to be able to discharge pressure to 0 and remove the welded pipe, the end of the welding.
Galvanized welded with 2.5mm welding rod can be, but docking difficulties, or lap fillet easier, and certainly the galvanized layer weld is not very good, because the galvanized zinc metal is a low melting point, when welding zinc layer boiling explosion, the weld forming variation; also because Zinc Oxide is poisonous do the exhaust smoke so as not to affect the health of welding.
1, pipe and joint surface to ensure smooth, clean, no oil.
2, the pipe into the pipe fitting, good direction, angle, and mark.
3, the installation of welding pipes and pipe fittings, inserted into the self adjustable heating type hot melt welder mould, switch the machine on and wait for a moment, when the green light flashes that have reached the welding temperature, welding work can be carried out.
4, the pipeline smoothly and evenly into the pipe fittings interface.
5. In the next few seconds after the pipe joint is inserted into the pipe fitting, the pipe and pipe fittings must be adjusted to the marked position.
6, after a few minutes of cooling, welding joint can reach the standard strength, complete the welding work.
