304 and 316L stainless steel materials are the only health materials that can be implanted into human body, so for water supply pipes, stainless steel pipes are the most beneficial to health. In the immersion water test, all the indicators meet the requirements of the relevant national drinking water standards. Stainless steel pipeline has smooth inner wall, no fouling, no bacterial contamination, anti-bacterial, anti-seismic, anti-tension, high pressure and high temperature resistance, no need to worry about water quality, and can prevent secondary pollution of water.Thin wall stainless steel water supply pipe is recognized as one of the best pipes with comprehensive properties
304, 316 L thin-walled stainless steel water pipes and pipe fittings series products are widely used in star hotels, medical and health, fire protection, housing, water, food, beverage, schools, airports, subways, high-speed rail, industry, education, ships, industrial desalination projects, drinking water, direct drinking water, cold and hot water, gas and other system fields of large and medium-sized construction projects, and the product sales network has been widely spread It has been exported to Europe, Southeast Asia and other countries and regions, and has established partnerships with many enterprises around the world, with a very broad prospect.
在不锈钢管的JIS标准里，按其规格（用途）的不同，规定了这些项目的数值。线材只指定了抗拉强度，而结构钢不仅规定了屈服强度，还规定了残余伸长应力、断后伸长率、断面收缩率等。不锈钢管抗拉试验，就是夹住标准试样的两端，慢慢拉伸到断裂为止。无法保证试样和实物的一致，但是只要在大企业生产，且进行了足够的质量管理，就不应有大的差异。特别是热处理过的，就不存在实物与试样不一致的担心。
