Precautions for using PE pipe welding machine
PE pipe welding machine is a more sophisticated equipment, and it has certain dangers. Please pay attention to it when using:
1. When handling pipes and fittings, be careful to handle them carefully to avoid oil pollution, severe impacts are strictly prohibited, and collision with sharp objects, throwing, dropping, dragging, etc., to avoid causing impact on the pipes, mechanical damage, etc. There is a certain degree of brittleness at low temperatures (-5 ° C), so be careful during winter construction, and use sharp scissors to cut slowly when cutting.
2. PE pipes are prone to aging when exposed to ultraviolet rays for a long time. When installed outdoors or in direct sunlight, they must be covered with a dark protective layer. Pipes and fittings should be placed in a well-ventilated warehouse or simple shed to prevent direct sunlight, and the distance from the heat source should not be less than 1 meter.
PE管焊接机 防潮和脏物污染。 3. When hot-melt connection, please observe the safe operation rules of electrical tools, pay attention to moisture and dirt pollution of PE pipe welding machine .
4. During the welding process, there must be no water, oil, or dirt at the interface of the welded pipe fittings to prevent false welding and cause hidden dangers of water leakage.
PE管焊接机 的温度达到规定的要求（ 200℃～235℃）时方可进行焊接操作。 5. When welding, the temperature of the PE pipe welding machine must meet the specified requirements ( 200 ° C ~ 235 ° C) before the welding operation can be performed.
6. It is not allowed to directly weld pipes with different pipe diameters, and the intermediate pipes should be connected with matching pipe fittings.
PE管焊接机 表面温度很高，焊接操作者一定要小心烫伤，在不用 PE管焊接机 时应关闭电源，将其放置在不易被人接触的地方，以防 发生烫伤事故。 7. During normal welding, the surface temperature of the PE pipe welding machine is very high. The welding operator must be careful of burns. When the PE pipe welding machine is not in use , the power should be turned off and placed in a place that is not easily accessible to prevent burns. accident.
切割管材时，端面必须与管材轴线垂直，不能有斜口。 8. When cutting the pipe, the end face must be perpendicular to the pipe axis and there must be no oblique opening.
、插入管材前，必须对管材和管件内、外表面进行清洁，不得带有泥沙、水等任何杂质。 9. Before inserting the pipe, the inner and outer surfaces of the pipe and fittings must be cleaned without any impurities such as sand, water, etc.
、插入管材前，应刮掉管材和插口管件表面的氧化层，刮削时，应量出需刮削的区域，沿管材或插口管件的整个圆周均匀刮削。 10. Before inserting the pipe, the oxide layer on the surface of the pipe and the socket pipe should be scraped off. When scraping, the area to be scraped should be measured and scraped uniformly along the entire circumference of the pipe or socket pipe.
、管材必须插到位，并使管材与管件保持平行，为了确保管材的穿插到位，需在插口端做好插入深度标志。 11. The pipe must be inserted in place, and the pipe must be parallel to the pipe fittings. In order to ensure that the pipe is inserted in place, the insertion depth mark must be made at the socket end.
、焊接时应采用相配套的电熔 PE管焊接机 （交流电压 39.5V）。 12. When welding, the matching electric fusion PE pipe welding machine (AC voltage 39.5V) should be used .
、合理掌握插口端氧化层的刮削量 ,严禁用重物敲击过量装配。 13. Reasonably grasp the scraping amount of the oxide layer on the socket end , and it is strictly prohibited to hit excessive assembly with heavy objects.
、焊接 D110以上规格管件时应在管材两端采用紧固夹具，确保管材在焊接过程中受熔融料的压力而外移。 14. When welding pipe fittings above D110 , fastening fixtures should be used at both ends of the pipe to ensure that the pipe is moved outward by the pressure of the molten material during the welding process.
