Precautions for PE threading PE pipe
PE穿线管材 和管件时，应小心轻放，避免油污，严禁剧烈撞击，与尖锐物品碰撞和抛、摔、拖，避免造成对 PE穿线管材 的冲击、机械损伤等。 1. When handling PE threaded pipes and fittings, handle them carefully to avoid oil stains, avoid severe impacts, collide with sharp objects and throw, drop, drag, and avoid impacts and mechanical damage to PE threaded pipes . There is a certain degree of brittleness at low temperature ( -5 ℃), so be careful during winter construction, use sharp scissors to cut slowly when cutting.
PE穿线管材 长期受紫外线照射易老化，安装在户外或阳光直射处时必须包有深色保护层。 2. PE threaded pipe is prone to aging when exposed to ultraviolet rays for a long time. It must be covered with a dark protective layer when installed outdoors or in direct sunlight. 应放在通风良好的库房或简易棚内，防止阳光直射，距离热源不得小于 1米。 PE threaded pipe 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.
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.
PE穿线管材 件接口部位不能有水、油污、脏物，以防假焊，造成漏水的隐患。 4. During the welding process, there must be no water, oil, or dirt at the interface of the welded PE threaded pipe fittings to prevent false welding and cause hidden dangers of water leakage.
5. When welding, the temperature of the PE pipe welding machine must meet the specified requirements (200 ° C ~ 235 ° C) before the welding operation.
PE穿线管材 直接焊接在一起，其中间应该用相配套的管件进行过渡连接。 6. It is not allowed to directly weld PE threaded pipes of different pipe diameters together, and the intermediate pipe should be connected with the matching pipe fittings.
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 used, the power should be turned off and placed in a place that is not easily accessible to prevent burns. accident.
PE穿线管材 时，端面必须与 PE穿线管材 轴线垂直，不能有斜口。 8. When cutting PE threaded pipe , the end face must be perpendicular to the axis of PE threaded pipe , and there must be no oblique opening.
PE穿线管材 前，必须对 PE穿线管材 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 PE threading pipe , the inner and outer surfaces of the PE threading pipe and fittings must be cleaned without any impurities such as sand, water and the like.
PE穿线管材 前，应刮掉 PE穿线管材 和插口管件表面的氧化层，刮削时，应量出需刮削的区域，沿 PE穿线管材 或插口管件的整个圆周均匀刮削。 10. Before inserting the PE threading pipe , the oxide layer on the surface of the PE threading 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 PE threading pipe or socket pipe.
PE穿线管材 必须插到位，并使 PE穿线管材 与管件保持平行，为了确保 PE穿线管材 的穿插到位，需在插口端做好插入深度标志。 11. The PE threading pipe must be inserted in place, and the PE threading pipe must be parallel to the fittings. In order to ensure that the PE threading pipe is inserted in place, the insertion depth mark must be made at the socket end.
12, when welding should use the matching electric fusion PE pipe welding machine (AC voltage 39.5V).
13. Reasonably grasp the scraping amount of the oxide layer on the socket end, and it is strictly forbidden to hit excessive assembly with heavy objects.
规章制度办事。 There is a certain danger in processing PE threaded pipe, and it must be handled in accordance with rules and regulations.
