怎樣選擇優質的冷拔鋼管是一個難題

優質冷拔鋼管質量有保障，使用壽命長，選購商品都希望選擇質量好的，面對市場上眾多的產品，如何在其中選擇出比較優質的產品是一個難題，新產品的表面都是差不多的，如果單單环氧地坪隻從表面查看不易辨別產品的質量。冷拔鋼管的選擇從它的管壁厚度方面查看，管壁的厚度和鋼材的性質有關，不得小於由於運輸、裝卸、安裝等环節所需要的最小壁厚。通常鋼管規格(包括厚度和鋼號)的變化不超過4種，在選擇管材方面出入不會很大，畢竟要求的鋼管的規格就幾種，從厚壁方面選擇出入不大。
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.
其次在焊接方面選擇，焊接技術辨別方法很容易區分，這個是從表面很容易辨別的，焊接的接口平整順滑程度都可看出冷拔鋼管的質量，焊接技術要求技術人員的熟練掌控。
Secondly, in the as彩色沥清地坪pect 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.
