1、不锈钢水管缺点—安全无毒

不锈钢材料是可以植入人体的健康材料，所以对供水管来说，选用不锈钢管道是有利健康的。浸泡水试验，各项指标均符合国家有关饮用水标准要求。不锈钢管道内壁光滑，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。

2、不锈钢水管缺点—选材讲究

所有原材料采用牌号为304、304l、316、316l，均符合jis4305要求。以上牌号具有性能稳定、强度高、热膨胀系数低等特点。

3、不锈钢水管缺点—使用周期长

不锈钢表面薄而致密的富铬氧化膜，使得不锈钢水管在包括软水在内的所有水质中都具有良好的耐腐蚀性，即使埋地使用也有优良的耐蚀性;实地腐蚀试验数据表明，不锈钢水管的使用寿命可达100年，寿命周期内几乎不需要维护，避免了管道更换的费用和麻烦，综合使用成本低。

4、不锈钢水管缺点—使用性能好

不锈钢可以在-270℃-400℃的温度下长期安全工作，无论是高温还是低温，都不会析出有害物质，材料性能相当稳定;不锈钢水管抗拉强度大于530 n/mm ，而且具有良好的延展性和韧性。不锈钢水管的高强度，极大地降低了受外力影响漏水的可能性，显著降低了水的渗漏率，使水资源得到有效的保护和利用。

5、不锈钢水管缺点—减少运输成本

不锈钢管道内壁光滑，水阻非常小，减少了压力损失，降低了输送成本。由于不锈钢的热膨胀系数低，在热水管道中有效的降低了热能损耗。不锈钢材料是100%可以再生的材料，不会给环境造成公害。

不锈钢水管是一种寿命周期成本低的长寿材料，健康卫生的绿色材料，可持续发展的环保材料。发达国家基于人体健康和寿命周期成本的考虑，不锈钢水管的应用已日趋普及。我国进入21世纪特别是加入wto后，也急需提高产品档次，以改变塑料管、复合管远不能完全适应供水管系的需要和满足国家对饮用水品质要求的现状，限度地实现人民提高生活质量为目标。健康饮水就从选择304不锈钢水管开始!

xingdaye stainless steel water pipe safety, environmental protection, health, zero maintenance, to eliminate the secondary pollution of water quality, the price is appropriate, is a high-quality water pipe material. after several decades of practical use, it has been proved that stainless steel material has excellent corrosion resistance, sanitation, rust free, scale free, precipitate free, self-cleaning, long life and recyclability, which is an excellent bearing body of human drinking water pipeline at this stage. stainless steel pipes have become a trend in developed countries such as europe and the united states. the main reason why the tap in japan can be opened and drunk is that the quality of drinking water does not change in the process of flowing through the end-user after coming out of the water plant. 99% of tokyo water pipe network in japan uses stainless steel pipes. since 1999, stainless steel pipes have been used in china. from the perspective of market use, the share of thin-walled stainless steel pipes is gradually expanding. foshan xingdaye metal material co., ltd. is a private enterprise integrating scientific research, manufacturing and sales. its main products include socket pipe fittings, flanges, etc. material: carbon steel, stainless steel, alloy steel. foshan xingdaye metal materials co., ltd. has the production process, production equipment and test and detection system, which can be designed and manufactured according to the needs of different customers by adopting chinese gb, gb / t, hgj, shj, jb, american ansi, astm, mss, japanese jis and international iso standards. the products are characterized by smooth internal and external surfaces, small physical dimension error, uniform wall thickness, fine metallographic structure, good mechanical properties, corrosion resistance and long service life. the products are widely used in petroleum, chemical industry, papermaking, food, beer, electric power, shipbuilding, natural gas and other industries, with reliable quality, reasonable price and thoughtful service, which are well received by all walks of life. welcome to inquire and ask for more detailed information. we sincerely look forward to your support and cooperation, seek common development and win-win situation. 1. disadvantages of stainless steel water pipes - safe and non-toxic stainless steel materials can be implanted into human health materials, so for water supply pipes, the selection of stainless steel pipes is beneficial to health. in the test of soaking water, all indexes are in accordance with the requirements of relevant national drinking water standards. the inner wall of stainless steel pipe is smooth, so it will not scale and be easily contaminated by bacteria after long-term use. it is not necessary to worry about the impact of water quality, and it can also prevent the secondary pollution of water. 2. disadvantages of stainless steel water pipe: the material selection shall be based on the grades of 304, 304l, 316 and 316l, all of which meet the requirements of jis4305. the above brands have the characteristics of stable performance, high strength and low coefficient of thermal expansion. 3. disadvantages of stainless steel water pipes - the thin and dense chromium rich oxide film on the surface of stainless steel pipes with long service life makes the stainless steel water pipes have good corrosion resistance in all water quality, including soft water, even if they are buried in the ground, they also have excellent corrosion resistance; the field corrosion test data show that the service life of stainless steel water pipe can be up to 100 years, almost no maintenance is needed in the service life cycle, which avoids the cost and trouble of pipe replacement, and the comprehensive use cost is low. 4. disadvantages of stainless steel water pipe - good performance stainless steel can work safely for a long time under the temperature of - 270 ℃ - 400 ℃. no matter at high or low temperature, harmful substances will not be separated out, and the material performance is quite stable; the tensile strength of stainless steel water pipe is greater than 530n / mm, and it has good ductility and toughness. the high strength of stainless steel water pipe greatly reduces the possibility of water leakage affected by external forces, significantly reduces the leakage rate of water, and effectively protects and utilizes water resources. 5. disadvantages of stainless steel water pipe - reduce the transportation cost. the inner wall of stainless steel pipe is smooth, the water resistance is very small, the pressure loss is reduced, and the transportation cost is reduced. due to the low coefficient of thermal expansion of stainless steel, the heat loss is effectively reduced in the hot water pipeline. stainless steel material is 100% renewable material, which will not cause environmental pollution. 1. stainless steel drainage pipe shall refer to gb / t12771-2008, gb / t12771-2011, cj / t152-2010 and other relevant national standards and industry standards; there are many specifications from dn50 to dn600; the inner wall of the pipe is smooth, without scaling, sanitation, pollution and corrosion resistance, which can reach 100 years. 2. the above description is only a preliminary introduction of stainless steel drainage pipe, for reference only. if there is any mistake or leakage, please understand. for more information, please call for stainless steel drainage pipe information or visit our company for details. the company has the right to modify or supplement the parameters according to the technical improvement without notice. the actual data shall be subject to the order and delivery. product features: stainless steel drainage pipe with safety and health, high strength, good corrosion resistance, durable, long life, maintenance free, beautiful and other features. application: stainless steel drainage pipe is widely used in water supply and drainage system, fire fighting system, gas pipeline system, etc. executive standards: refer to gb / t12771-2008, gb / t12771-2011, cj / t152-2010 and other relevant national standards and industry standards for stainless steel drainage pipes. stainless steel water pipe is a kind of long-life material with low life cycle cost, healthy and healthy green material, and environmental protection material with sustainable development. based on the consideration of human health and life cycle cost in developed countries, the application of stainless steel water pipe has become more and more popular. in the 21st century, especially after china's accession to the wto, it is also urgent to improve the quality of products, so as to change the status quo that plastic pipes and composite pipes are far from meeting the needs of water supply system and the requirements of the country for drinking water quality, so as to achieve the goal of improving people's living quality. healthy drinking water starts with 304 stainless steel pipe!
