方矩管不能淋雨大家一定要注意!

  许多建筑行业的资深人士都曾说过,矩形钢管是绝对不允许下雨的,在储藏时一定要放在室内,而不能像其他钢材那样直接放在室外。这是为什么呢?济南镀锌管公司小编告诉你,这是因为长方形的管子是铁制的,雨后会生锈的。因此,当矩形管被储存时,它一定不能下雨。

  Many senior people in the construction industry have said that rectangular steel pipes are absolutely not allowed to rain, and they must be stored indoors rather than directly outdoors like other steel products. Why is this? Jinan galvanized pipe company told you that this is because the rectangular pipe is made of iron and will rust after rain. Therefore, when the rectangular tube is stored, it must not rain.

  1. 如需长时间存放,从存放之初起,应使用不透明的覆盖物进行保护,避免腐蚀、腐蚀涂层老化、翘曲等矩形管的现象。

  1. If it needs to be stored for a long time, the opaque covering shall be used for protection from the beginning of storage to avoid corrosion, aging of corrosion coating, warping and other rectangular pipes.

  2、封面应牢固耐用,防止长时间日晒雨淋和腐朽渗漏。

  2. The cover shall be firm and durable to prevent long-term sun, rain and rot leakage.

  3.当矩形管被覆盖时,钢管的表面应通风,以避免水汽在其表面积聚。

  3. When the rectangular pipe is covered, the surface of the steel pipe shall be ventilated to avoid the accumulation of water vapor on its surface area.

  4. 储存矩形钢管时,应有支撑,并与地面保持一定距离,以保证钢管的通风。

  4. When storing rectangular steel pipes, they shall be supported and kept a certain distance from the ground to ensure the ventilation of steel pipes.

  5. 矩形管堆放存放后,应取下管端保护器,以免管端保护器与钢管接触面上积水,不易挥发。

  5. After the rectangular pipe is stacked and stored, the pipe end protector shall be removed to avoid water accumulation on the contact surface between the pipe end protector and the steel pipe, which is not easy to volatilize.

  6. 矩形钢管存放时应注意叠层数,避免叠层过多导致管端局部受力,导致钢管径向塑性变形,损伤防腐层。建议光管堆放层数参照《管道与钢管铁路运输规范》或APIRP 5l1-2009《船舶与远洋船舶管道与钢管运输规范》。也可以通过试验确定或根据钢管的安全堆垛高度进行。防腐管的叠层数按GB/T 23257-2009《埋地钢管聚乙烯防腐层》执行。

  6. Pay attention to the number of layers when storing the rectangular steel pipe, so as to avoid the local stress at the pipe end caused by too many layers, resulting in the radial plastic deformation of the steel pipe, and damaging the anti-corrosion coating. It is suggested that the number of stacking layers of bare pipes should refer to the code for railway transportation of pipelines and steel pipes or the code for transportation of pipelines and steel pipes of ships and ocean going ships (apirp 5l1-2009). It can also be determined by test or according to the safe stacking height of steel pipes. The number of layers of anticorrosive pipes shall be in accordance with GB / T 23257-2009 polyethylene anticorrosive coating for buried steel pipes.

  7. 储存时应避免接触油类、铜类等污染物。

  7. Avoid contact with oil, copper and other pollutants during storage.

  8. 制定矩形管道长时间存放的系统文件,并根据系统实施。

  8. Develop system documents for long-term storage of rectangular pipes and implement them according to the system.

  更注意矩形管的存放,同时我们也要避免过多的层数,以保证其通风,以免生锈、变形或损坏防腐层。如果出现生锈问题是由于矩形管存放不当,可以联系我们,济南镀锌管厂家,我们帮您分析,一起看看如何解决这个问题。

  Pay more attention to the storage of rectangular pipes. At the same time, we should avoid too many layers to ensure the ventilation, so as to avoid rust, deformation or damage to the anti-corrosion coating. If the rust problem is due to improper storage of rectangular pipes, you can contact us, Jinan galvanized pipe manufacturer, we can help you analyze and see how to solve this problem.
