在日常生活中,我们也可能会遇到管道破裂,或者是对路面进行修整的时候,挖机不小心碰到PE,PPR给排水管道的时候,这种情况下该怎样应急处理呢?市面上常用的PE抢修节究竟是什么?如何使用呢?接下来润硕管业一一解答:

PE管补洞需要根据实际情况来定

  ①临时加急抢修,可以用抢修节或者哈夫节临时处理,但是维持时间一般在一年以内。

  ②可以把破漏部分切割掉,两端切口平整,平整端口与法兰热熔连接,两套法兰与钢片相连。

  ③如果管道沉降比较严重,并且破坏面积比较大,这时候就要把漏洞管处切割处理,用电熔弯头或者电熔直接加上短节链接管道。

  ④如果管子的口径小,可以切割漏洞部分,用直接热熔连接(不常用)。

PE管道发生漏水

处理PE管漏水方法

一、对于漏水程度比较轻微的需要进行局部补漏

  1、管壁裂缝漏水:关于铸铁管管壁裂缝漏水可选用管卡修补;管卡系选用10mm厚的钢板做成两个半圆管子,比裂缝长30mm,内圆半径为修补管道外径,内衬 3mm厚橡胶板,管卡安装好后,用螺栓拧紧。关于PE管管壁裂缝漏水选用同标准、同资料的塑料管箍或疾速接头或许PE抢修节修补。

  2、接口漏水:关于铸铁管接口如选用灰口,可先将灰口外表剔掉约 0.5~1.0mm,再对灰口剔凿部位作洁净处置,然后将清理过的灰口用环氧水泥砂桨填实,把灰口外表抹平即可。关于铅接口,则可除掉铅口,从头灌铅、打实。关于PE管材接口漏水,可选用同标准、同资料的相应pe管件修补,行将接口处管道连同pe管件一同锯掉,再将新配pe管件与原管道衔接,锯切掉管道时,长度欠好把握,需求经验丰富的管道工操作。

二、对于漏水程度比较严重的需要重新更换聚乙烯PE管

  当PE管道损坏严峻无法修补或修补费用较大时,就要思考悉数更新管道。

PE抢修节的使用方法:

  1.安装使用中,必须保证管道外表面清洁。 由于使用的管道在地下埋的时间过长, 非金属 管件表面会附着很多泥土,大都被腐蚀,管件表面会被氧化生锈、甚而变形,只有进行必要的清理和稍加整形后才能使用抢修节,内侧表面才能与管件表面贴合完整。

  2.要注意安装时的角度问题。在安装客件两部分吻合后,再将螺丝上紧,上螺丝时要保 证抢修节两侧受力平衡,四面与管道完全接触没有缝隙,压力适中,才能避免漏水。

  3.还有一个应当注意的问题,胶圈是否平整。如果胶圈卷曲或者在上螺丝过程式中将胶 圈隔断,也不能起到密封效果。

  4.抢修节在使用的时候要先把堵头卸下来放空安装好后再堵上.

PE抢修节

  在现阶段PE管材管件已经开始应用于大城市,像深圳广州上海北京这些城市在给排水用管上都在使用PE管材,但由于在使用过程中有时水压过大而导致水管爆破的,只要长度不要太长,使用抢修节不仅方便快捷,而且也保险。

In our daily life, we may also encounter pipe cracks, or when repairing the road surface, when the excavator accidentally touches the PE or PPR water supply and drainage pipes, how should we deal with emergency situations in this case? What is the common PE repair festival on the market? How to use it? Next, Runshuo Pipe Industry will answer one by one:

PE pipe filling hole needs to be determined according to the actual situation

  ①Temporary urgent repairs can be handled temporarily at the Emergency Repair Festival or the Half Festival, but the maintenance time is generally within one year.

  ②The leaking part can be cut off, the two ends are cut flat, the flat port is connected with the flange by heat fusion, and the two sets of flanges are connected with the steel sheet.

  ③If the pipeline subsidence is serious and the damaged area is relatively large, cut the leaky pipe at this time, and use electric fusion elbow or electric fusion to directly add the short link pipe.

  ④If the diameter of the pipe is small, the leaky part can be cut and connected by direct heat fusion (not commonly used).

PE pipe leaks

How to deal with PE pipe leakage

1. For minor leaks that need to be partially patched

1. Water leakage from pipe wall cracks: Regarding the water leakage of cast iron pipe wall cracks, pipe clamps can be used to repair; the pipe clamp system uses 10mm thick steel plate to make two semicircular pipes, which are 30mm longer than the crack. The inner radius is the outer diameter of the repaired pipe. Lining  3mm thick rubber sheet, after the pipe clamp is installed, tighten it with bolts. Regarding the leakage of PE pipe wall cracks, use plastic pipe clamps or quick joints of the same standard and the same materials or PE emergency repair joints.

2. Water leakage at the interface: For the cast iron pipe interface, if a gray port is selected, the surface of the gray port can be removed by about  0.5~1.0mm, and then clean the picking part of the gray port, and then use epoxy cement for the cleaned gray port Fill it with sand paddles and smooth the surface of the ash. Regarding the lead interface, the lead port can be removed, and the lead can be poured from the beginning to make a solid. Regarding the leakage of the PE pipe interface, you can choose to repair it with the corresponding pe pipe fittings of the same standard and the same data. The pipe at the interface and the pe pipe fitting can be sawn off, and then the new pe pipe fitting is connected with the original pipe. When the pipe is sawn off, the length is not good. Grasping, requires experienced plumber operations.

2. For serious water leakage, the polyethylene PE pipe needs to be replaced

   When the PE pipe is severely damaged and cannot be repaired or the repair cost is high, it is necessary to think about all the renewal of the pipe.

How to use PE repair section:

   1. During installation and use, the outer surface of the pipeline must be clean. Due to the long time that the used pipelines are buried in the ground, a lot of soil will adhere to the surface of the non-metallic pipe fittings, and most of them will be corroded. The surface of the pipe fittings will be oxidized, rusted, and even deformed. The repair joint can only be used after necessary cleaning and slight shaping. , The inside surface can be intact with the surface of the pipe fitting.

   2. Pay attention to the angle of installation. After the two parts of the installation guest are matched, tighten the screws again. When installing the screws, ensure that the forces on both sides of the emergency repair section are balanced, and the four sides are in full contact with the pipe without gaps, and the pressure is moderate to avoid water leakage.

  3. There is another problem that should be paid attention to, whether the rubber ring is flat. If the apron is crimped or the apron is separated during the screwing process, the sealing effect will not be achieved.

  4. When the emergency repair section is used, the plug must be removed first to empty it and then plug it after installation.

PE Repair Festival

At this stage, PE pipe fittings have begun to be used in big cities. Cities like Shenzhen, Guangzhou, Shanghai, and Beijing are all using PE pipes for water supply and drainage pipes. However, because of the excessive water pressure during use, the water pipes may burst. The length should not be too long. It is not only convenient and quick to use the repair section, but also safe.
