Stainless Steel Pipe-Encyclopedia

For water supply pipes, 304 and 316L stainless steel materials meet all national drinking water standard requirements in immersion water tests. The smooth inner wall of stainless steel pipes prevents scale buildup and bacterial contamination over long-term use, offering antibacterial, anti-shock, tensile, high-pressure, and high-temperature resistance. This minimizes water quality impact and effectively prevents secondary pollution. Thin-walled stainless steel water pipes are widely recognized as one of the best-performing pipe materials

提到304不锈钢水管,大家都很熟悉,而304不锈钢水管种类比较多,常见的有304不锈钢装饰管和卫生食品级不锈钢304水管,其实这二种水管有很大的区别,下面小编为大家介绍其区别处。

生产工艺不同:

卫生食品级不锈钢304水管最小规格DN15的水管壁厚为0.6mm——0.8mm,允许偏差不超过公称壁厚的±10%,焊缝要求质量比较高,压扁、扩口、弯曲、拉伸试验性能要求很高,其试验水压要求达到2.5Mpa以上。生产效率一般都在1.5米/分钟,而且生产过程中必须要进行在线的涡流探伤检测,有时还必须做水压试验。

304不锈钢装饰管的壁厚没有明确规定,焊缝的质量要求不高,对管材所承受的压力也没有明确要求,生产速度很快,生产效率能达到20米/分钟。

采用的标准不同:

卫生食品级不锈钢304水管采用的标准是GB/T29038-2012《薄壁不锈钢管道技术规范》。所含的重金属镍、硫、磷、铅、6价铬的重金属迁移量在标准之内,长期使用不会积垢、不易被细菌粘污,无须担心水质受影响,更能杜绝水的二次污染。

304不锈钢装饰管采用的标准是GB/T18705-2002《装饰用焊接不锈钢管》,不能直接与食品接触及用作饮用水管道。

应用领域不同:

卫生食品级不锈钢304水管多用于给排水管道、燃气管道、食品加工输送管道、医疗输送管道等领域;304不锈钢装饰管多用于工业、家装装饰等领域。

以上是304不锈钢装饰管与卫生食品级不锈钢304水管的区别,了解这些区别,使用时便能更好的选择。
