Now that we have bought the cold-drawn steel pipe, we all hope to maximize its utilization. How can we make better use of cold-drawn steel tubes? This requires us Liaocheng Ronghe Metal Material Co., Ltd. to keep improving the process in the production of cold-drawn steel tubes, and to maximize the service life of cold-drawn steel tubes. We produce cold-drawn steel tubes of different materials, elements are naturally different. Generally speaking, our cold-drawn steel pipe is not easy to rust. But it doesn't mean that since cold-drawn steel pipe is not easy to rust, we usually don't need to care about it, we can put it aside directly and have a good rest. Because if the cleavage of cold-drawn steel tube is not carefully maintained, its service life will be shortened, and it will also bring unnecessary losses to our cold-drawn steel tube factory and customers. Since you buy cold-drawn steel pipe is bound to hope that the service life can be longer, so we should pay attention to the maintenance of cold-drawn steel pipe. 冷拔钢管在工艺上要增加寿命，首先就要对冷拔钢管进行酸洗去除表面氧化皮，然后经过润滑处理，这样对钢管进行酸洗、钝化表面处理，使表面形成一层保护膜。. 然后酸洗过后再用电解方法进行一次补充就可以让冷拔钢管得到更进一步的保护这样经过大家出厂的冷拔钢管能够最大的增加他的使用寿命，提高利用率。
In order to prolong the service life of cold-drawn steel pipes, it is necessary to acid-wash the cold-drawn steel pipes to remove oxide scales on the surface, and then lubricate them. In this way, the steel pipes are acid-washed and passivated to form a protective film on the surface. After pickling, the cold-drawn steel pipe can be further protected by adding electrolytic method once again, so that the service life of the cold-drawn steel pipe can be maximized and the utilization rate can be increased.
