怎样确定厚壁焊管是优质的重要关键.石油、天然气等液体的运输一直是个值得注意的问题,因为它们在运输过程中有很大的危险存在,一旦出现泄漏事故,将给人们带来很大的损失,甚至威胁人类的生命安全呢,因此选用的厚壁焊管一定要保证质量。猜你可能会喜欢对厚壁无缝焊管做简要介绍。那么在选择厚壁焊管时要注意什么问题呢?首先要注意它的厚度,管径必须大于0.02,因为只有这样的承受的压力才大,即使用力拉,才不会发生断裂。其次要看它的表面是否光滑,劣质的厚壁焊管表面常有结成的疤痕,有的还有细小的裂纹,它的表面缺少光泽,一看到这样的焊管,就要知道这不是上等的焊管。

How to determine the thick-walled welded pipe is an important key to high quality. The transportation of oil, natural gas and other liquids has always been a noticeable problem, because they have a great danger in the process of transportation, once there is a leakage accident, it will bring great losses to people, and even threaten the safety of human life. Therefore, the thickness chosen is very thick. The wall welded pipe must ensure the quality. Guess you might like to give a brief introduction to thick walled seamless welded pipe.

So what should we pay attention to when choosing thick wall welded pipe? First of all, pay attention to its thickness, diameter must be greater than 0.02, because only such a large pressure to bear, even if stretched, will not break. Secondly, it depends on whether its surface is smooth, poor quality thick-walled welded pipe surface often has formed scars, and some have small cracks, its surface is lack of gloss, see such welded pipe, we must know that this is not a first-class welded pipe.

再者,你还要从不同的地方来量一下管径。看看不同的地方是否相同,优质的焊管应该各个地方都是大约相同的,否则就是劣质的。 大家在选择时一定要选择大厂家的,一般都有严格的包装,包装比较松散的,往往是不规范的。

Besides, you have to measure the diameter from different places. To see if the different places are the same, high quality welded pipe should be about the same everywhere, otherwise it is inferior. We must choose big manufacturers when choosing, generally have strict packaging, packaging is loose, often not standardized.
