怎样选择优质的冷拔钢管是一个难题

优质冷拔钢管质量有保障,使用寿命长,选购商品都希望选择质量好的,面对市场上众多的产品,如何在其中选择出比较优质的产品是一个难题,新产品的表面都是差不多的,如果单单只从表面查看不易辨别产品的质量。冷拔钢管的选择从它的管壁厚度方面查看,管壁的厚度和钢材的性质有关,不得小于由于运输、装卸、安装等环节所需要的最小壁厚。通常钢管规格(包括厚度和钢号)的变化不超过4种,在选择管材方面出入不会很大,毕竟要求的钢管的规格就几种,从厚壁方面选择出入不大。

The quality of high quality cold-drawn steel pipes is guaranteed, the service life is long, and the commodities are expected to be selected with good quality. Faced with many products on the market, how to select the better quality products is a difficult problem. The surface of new products is similar. If only looking at the surface, it is difficult to distinguish the quality of products. The selection of cold-drawn steel pipe is based on its wall thickness. The thickness of the pipe wall is related to the properties of steel, and should not be less than the minimum wall thickness required for transportation, loading and unloading, installation and other links. Usually there are no more than four kinds of steel pipe specifications (including thickness and steel number), and there will be no big difference in the selection of pipe materials. After all, there are several required steel pipe specifications, and there is little difference in the selection of thick wall.

其次在焊接方面选择,焊接技术辨别方法很容易区分,这个是从表面很容易辨别的,焊接的接口平整顺滑程度都可看出冷拔钢管的质量,焊接技术要求技术人员的熟练掌控。

Secondly, in the aspect of welding, the method of distinguishing welding technology is easy to distinguish. It is easy to distinguish from the surface. The quality of cold-drawn steel pipe can be seen from the smooth degree of welding interface. The welding technology requires skilled control of the technicians.
