Stainless Steel Pipe-Encyclopedia

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

为什么不锈钢水管大家都首选304材质不锈钢呢?

提到高温轴承,很多人可能不是很熟悉,它在机械行业应用较多,但是高温轴承往往一般需要使用润滑,你知道使用什么润滑比较好吗?  提到不锈钢水管,市场上很多人首选的就是304不锈钢水管,那么你知道为什么大家都要首选304不锈钢水管吗?今天小编就围绕这一问题跟大家谈谈。

    一、在价格上。一般而言304不锈钢水管价格是相对居中且性价比高的。430不锈钢(铁)由于不含镍元素,所以价格较为便宜。在300系不锈钢里面,304的价格,相比于304L和316,价格要相对便宜,304L就是低C不锈钢,生产工艺的差别造成价格比304不锈钢贵,而316L不锈钢由于含有MO(钼)元素,使其耐蚀性、和高温强度有较大的提高,但其价格就相当昂贵。

    二、连接方式。目前不锈钢水管的连接一般分为焊接式连接,螺纹式连接方式,压接式连接方式,焊接式施工麻烦,现场必须使用电,其焊接的部位温度高容易岀现贫铬现象,现场又不能进行固溶处理,使焊接部位容易生锈,而且这种焊接连接方式成本较高,一般用在厚壁和大口径管道上。螺纹式连接方式,加工程序多,精度要求大,一般适用于厚壁不锈钢管或需要活接处,挤压式连接是目前不锈钢水管应用最多的方式,有环压连接,卡压连接,卡粘等。

    三、加工性能。430不锈钢由于机械性能与工艺性能较差,拉伸加工后表面会出现轧钢方向条状缺陷。316不锈钢强度高,容易塑性加工。304不锈钢具有加工性能好,韧性高的特点,加工十分的方便,对于管件也容易进行设计。304L其加工性能和304类似,但由于碳元素含量低,在焊接后或者消除应力后,其抗晶界腐蚀能力优秀,在未进行热处理的情况下,亦能保持良好的耐蚀性。

    目前大多中小口径的不锈钢水管都是采用薄壁有缝管,由制管机把切好的钢带制成规定的尺寸,而管材之间就用管件连接,管件需要扩口,需要弯曲,对不锈钢材质的加工性能要求较高。安装的便利也是人们使用时很注重的一个点,专门为薄壁不锈钢管研制的压接式连接方式就快捷方便,连接效果好且安全可靠。

    从以上内容我们能够了解到,不管是在成本上,还是加工连接上,304不锈钢水管都有着一定的优势,这也是为什么很多人会首选的原因。
