廠傢介紹辨別偽劣冷拔鋼管的方法

鋼管是冷拔鋼管制作的主要材料，鋼管的質量直接影響冷拔鋼管的制作質量，選擇冷拔鋼管註意其質量問題，辨別偽劣產品，在眾多的產品中找出優質材料。冷拔鋼管辨別偽劣冷拔鋼管首先查看表面，質量差的鋼管表面會有麻面現象，容易結疤，表面並不是很光滑。註意觀察它的表面是否有劃痕，是否有裂紋存在，出現以上現象的冷拔鋼管一律定為偽劣產品。偽劣冷拔鋼管無金屬光澤，呈淡紅色或類似生鐵的顏色。
Steel pipe is the main material for cold-drawn steel pipe production. The quality of steel pipe directly affects the quality of cold-drawn steel pipe production. Pipe selection should pay attention to its quality problems, identify fake and inferior products, and find out high-quality materials in many products. Cold-drawn steel pipes distinguish fake and inferior stee环氧地坪l pipes by first looking at the surface, poor quality steel pipe surface will have hemp phenomenon, easy to scar, the surface is not very smooth. Pay attention to observe whether there are scratches and cracks on the surface of the steel pipe. The steel pipe with the abo透水地坪ve phenomena is considered to be fake and inferior products. The fake and inferior steel pipes have no metallic luster and are light red or similar to pig iron.
此外還有一部分要查看的是它的橫切面，優質鋼管的橫切面比較整齊，而偽劣材由於材質差，切頭端面常常會有掉肉的現象，即凹凸不平，並且無金屬光澤。根據以上的信息從表面查看冷拔鋼管鋼管的質量，辨別出偽劣產品，爭取選擇最優質的管材。
In addition, there is also a part to look at its cross-section, the cross-section of high-quality steel pipe is relatively neat, and fake and inferior materials due to poor material quality, the end of the cutting head often has the phenomenon of flesh loss, that is, uneven, and no metallic luster. According to the above information, the quality of cold-drawn steel pipe can be viewed from the surface, the fake and inferior products can be identified, and the best quality pipe can be selected.
