	很多刚入行的采购新人，第一次采购不锈钢焊管完全没有思路，只靠比价下单，经常出现材质选错、壁厚偷料、焊缝暗藏缺陷、无质检保障等问题，后期管路生锈渗漏、停工维修，额外增加大量成本。这份完整采购指南，分 6 大核心步骤，新手照着操作就能避开 90% 行业套路。

	二、核对规格壁厚，严防偷薄公差陷阱

	</li>
	<li data-track="13" style="box-sizing:border-box;margin:0px;padding:0px;list-style:decimal;border:0px;">
		低压常温管路选用常规壁厚；液压、换热、压力容器等高压场景按需加厚，不用盲目加厚浪费成本。
	</li>
	<li data-track="14" style="box-sizing:border-box;margin:0px;padding:0px;list-style:decimal;border:0px;">
		到货用卡尺随机抽检管材头尾、中段，避免商家标厚做薄，承压不足后期爆管。

	不锈钢管的强度和塑性是矛盾对立的二个方面
</p>
<p style="text-wrap:wrap;text-indent:2em;">
	在一般情况下，<strong><a href="http://www.jsbxghg.com/" target="_blank">无锡不锈钢管</a></strong>-310S不锈钢管强度和塑性是矛盾对立的二个方面，强度高，塑性就低。但下贝氏体组织具有较高强度和较高塑性与韧性的配合。在一定强度范围内，在强度相等时，下贝氏体的ak值高于回火马氏体。研究马氏体的性能证明，位错亚结构的马氏体具有较好的塑性和韧性，由此可知下贝氏体具有较高的塑性和韧性，是与它的亚结构高密度位错有很大关系。
</p>
<p style="text-align:center;">

</p>
<p style="text-wrap:wrap;text-indent:2em;">
	<span style="text-indent:2em;">必须指出，固溶体所间隙固溶的溶质原子对其塑性的损害是最为严重的，下贝氏体铁素体含有一定量的碳原子，但其中的碳部分地以碳化物形式脱溶出来，并且碳化物是细小而又分布均匀，这就有效地缩小了它对塑性的不利影响，而不缩小它对310S不锈钢管强度的有利作用，因此下贝氏体组织能够获得较高强度和较高塑性的协调配合。</span>

	一、看资质
</p>
<p style="text-indent:2em;">
	正规的<strong><a href="http://www.jsbxghg.com/" target="_blank">不锈钢管</a></strong>及管件生产企业，应当具备原材料质量检验报告及产品质量证明书。管道和管件上应清楚标明原材料、规格、生产批次和生产企业名称。
</p>
<p style="text-indent:2em;">
	二、看材质
</p>
<p style="text-indent:2em;">
	市面上不锈钢管常用的材质一般为304不锈钢。
</p>
<p style="text-indent:2em;">
	304不锈钢管是不锈钢管的入门标配，其耐腐蚀性及抗氧化性要比普通的201不锈钢高出不少。
</p>
<p style="text-indent:2em;">
	三、看厚度
</p>
<p style="text-indent:2em;">
	不锈钢管壁厚是决定其连接强度的关键。其质量要求不仅要保证管道连接的强度，还要具有在各种环境下的抗震性能、管道在各种外力冲激的性能，以及隐蔽工程中产品的使用寿命和腐蚀裕量。
</p>
<p style="text-align:center;">
	<a href="http://www.jsbxghg.com/" target="_blank"><img src="/Uploads/201910/5db63e32808ff.jpg" rel="external nofollow"  width="170" height="137" title="无锡不锈钢管厂家" alt="无锡不锈钢管厂家" /></a> 
</p>
<p>
	<br />
</p>
<p style="text-indent:2em;">
	目前，国内常见的不锈钢管，在相同公称通径(DN)下，国标厚度在0.8-2.0mm。
</p>
<p style="text-indent:2em;">
	四、看工艺
</p>
<p style="text-indent:2em;">
	不锈钢管的工艺取决于产品的细节，细节决定了管道的质量。
</p>
<p style="text-indent:2em;">
	比方说，管道内壁是否平衡光滑，管道壁厚是否均匀，管道端口切口是否平整、没有毛刺。
</p>
<p style="text-indent:2em;">
	五、看价格
</p>
<p style="text-indent:2em;">
	在挑选不锈钢管时，对比过不同不锈钢管厂家的产品后，一般还会再进行一个价格对比。不是说所有的东西，都是越便宜越好。我们需要对产品质量、厂家以及价格进行一个综合考虑，作出决定。

	对<strong><a href="http://www.jsbxghg.com/" target="_blank">不锈钢管件</a></strong>比较了解的都知道，不锈钢管件被氧化后容易在表面形成白斑，在出现这种情况后就要作出相应的处理，那么都有哪些处理方法呢?下面合创金属科技就来说下。
</p>
<p style="text-indent:2em;">
	1、外表打磨法。
</p>
<p style="text-indent:2em;">
	打磨可以使磨下来的铝末填充不锈钢管件的孔隙。
</p>
<p style="text-indent:2em;">
	2、高电压大电流密度冲击法。
</p>
<p style="text-indent:2em;">
	在阳极氧化前期采纳高电压、大电流冲击，使原先被杂质切割的大小不锈钢管件经过大电流冲击而衔接成片。
</p>
<p style="text-align:center;">

</p>
<p>
	<br />
</p>
<p style="text-indent:2em;">
	3、外表喷丸法。
</p>
<p style="text-indent:2em;">
	由于选用喷丸功率会得到大大的进步，因此这样的不锈钢管件经阳极氧化和染色后效果好。

</p>
<p style="text-indent:2em;">
	高品质的不锈钢材质，管子内部经过特殊处理，以避免管子被氧化，使其内表面光滑，永不腐蚀，具有304不锈钢的抗碱、酸腐蚀能力，确保了流经管路的压缩空气的质量。
</p>
<p style="text-align:center;">

</p>
<p>
	<br />
</p>
<p style="text-indent:2em;">
	可以随时随地从产气端输送高质量的空气到使用端，保证下游设备及生产工艺的连续性、稳定性和设备寿命。
</p>
<p style="text-indent:2em;">
	同时，有防腐蚀、免泄漏特性，长时间运行，保证了空气输送过程中的泄漏，有效的防止了能量损耗。
</p>
<p style="text-indent:2em;">
	光滑的内表面、全通径、内部导流等优化设计，降低了空气的流动阻力，使其管路压降减低，达到流量，从而降低由于压降引起的运行成本多达5%。(压降每减少1Bar，可减少装机功率7%的能耗)。
</p>
<p style="text-indent:2em;">
	采用高性能“O”型封闭圈，确保密封，无泄漏使用。没有空气泄漏意味着降低了运行费用。

　　随着人类文明的进步，人们生活水平的提高，金属类产品越来越得到人们的喜爱。而不锈钢管的发展也已经有了40年的历史，在我们国内不锈钢管也得到了广泛的应用。在很多领域都深受喜爱。那么不锈钢管的三大类都有哪三类呢？<br />
　　一：不锈钢装饰管<br />
　　不锈钢装饰管顾名思义就是用来做装饰的不锈钢管，主要的材质分为201，304和316不锈钢管，主要用于不锈钢防盗窗，楼梯扶手，护栏等。根据类别还可以分为普通管、花管，彩色管。<br />
　　普通管特点：生产工艺简单，品种规格较多。以不锈钢本色和拉丝磨砂为主。<br />
　　不锈钢花管特点：花管的出现改变了传统不锈钢管外观单一的特点，让人耳目一新。喜有沃各种花型齐全。
<p style="text-align:center;">
	<a href="http://www.jsbxghg.com/" target="_blank"><img src="/Uploads/201912/5deb145fed456.jpg" rel="external nofollow"  /></a> 
</p>
<br />
　　彩色不锈钢管特点：在不锈钢管表面镀一层颜色，任意规格皆可，在管材基础上按平方增加相应的加工费用。<br />
　　二：不锈钢工业管<br />
　　分为无缝管和焊管<br />
　　生产工艺：大多是不锈钢焊管，是用不锈钢卷带焊接而成的，而不锈钢卷带是经过热轧到一定厚度再压延冷轧到需要的薄厚度。不锈钢装饰管内壁有缝。不锈钢无缝管是通过冷拔方式生产，管壁无缝。<br />
　　管表面：喜有沃不锈钢装饰管是压延再加工做成的管材，表面会做抛光，所以管表面平整光滑有光泽。工业无缝管表面常是比较粗糙。<br />
　　厚度差别：304不锈钢装饰管厚度较薄，最薄能做到0.2mm，最厚只能做到5.0mm。但是工无缝不锈钢管一般都比较厚。<br />
　　应用范围：由于焊缝及厚度的限制，但是表面处理较好，所以多用于建筑装饰类产品、不锈钢制品等装饰性民用产品上。而不锈钢工业管无缝，管壁粗糙又厚，抗压能力较强，多用于满足高压、高强度、机械结构的产品使用。<br />
　　三：不锈钢制品管<br />
　　不锈钢制品管总的来说，就是制品生产商因普通不锈钢装饰管无法满足使用需求时，要求管材制造商专门定制的不锈钢管。<br />
　　它依据客户的不同需求，可细化成很多种不同的种类。如不锈钢家具管，卫浴管，水管，机械设备用管等。<br />
　　特点：对规格正负差、表面亮度做工等要求严格，会有弯管、扩缩等要求。<br />

　　在日常生活中，随处可见的不锈钢管制品越来越多，使用的不锈钢管材质也有所不同，有的使用304材质，有的是316材质，常常有人问304不锈钢管和316哪个贵，其实两者相比316更贵一些，今天就给大家分享一下两者的区别。<br />
　　304不锈钢密度为7.93g/㎝3，316不锈钢密度为8.03g/㎝3。从本质上看，二者并无明显差别，都是众多不锈钢的一种，具有耐酸、耐碱、便于加工、韧性高的特点。但要是再仔细划分，就能看出这两种材质的区别所在。<br />
　　首先在应用方面来说，304不锈钢管的使用领域比较广泛，他具有良好的耐蚀性。可用于防盗窗、楼梯扶手、防护栏、防盗门、汽车排气管、医护器具等等。
<p style="text-align:center;">
	<a href="http://www.jsbxghg.com/" target="_blank"><img src="/Uploads/201910/5db63e32808ff.jpg" rel="external nofollow"  /></a> 
</p>
<br />
　　而316在304的基础上增加了Ni、Cr、Mo元素，要比304的密度更高、耐腐蚀、耐高温能力更好，因此广泛应用于各种工业领域上（海水用设备、化学、染料，造纸、草酸、肥料等生产设备）。<br />
　　其次化学成分与性能方面对比：304不锈钢管化学名称为：06Cr19Ni10，316不锈钢管化学名称为：06Cr17Ni12Mo2。06表示含碳量低于0.08，Cr19表示含铬量为19，NI10表示含镍量为10。其中决定不锈钢管抗锈抗蚀的元素为镍，其价格也比较贵。<br />
　　304和316的纯度和厚度不一样，316耐腐蚀性相对要好一些，更能防锈。所以价格也会更贵一些。<br />
　　当然两者因用途不同，使用场景不同，我们在使用不锈钢管的时候根据适用场景选择合适的不锈钢管材，有些地方不一定就需要316不锈钢管，像北方干燥地区，使用304不锈钢管就已经足够了，耐腐蚀性好，不易生锈。但是如果用于南方沿海地区，污水处理厂等就需要使用316，不易腐蚀。<br />

<p style="text-indent:2em;">
	1、管材就是用于做管件的材料。不同的管件要用不同的管材，管材的好坏直接决定了管件的质量。建筑工程、电厂、化工厂等多用此类管材，有执行标准GB/T5310；用于高压锅炉：有执行标准GB/T8163；输送流体用无缝钢管：有执行标准GB3087。

</p>
<p>
	<br />
</p>
<p style="text-indent:2em;">
	2、低压锅炉用无缝钢管：有执行标准GB/T9948；石油裂化用无缝钢管：有执行标准GB/T14976；流体输送用不锈钢无缝钢管，常见材质有合金（15CrMo、12Cr1MoV）碳钢（10#、20#、45#）不锈钢（304、316）。
</p>
<p style="text-indent:2em;">
	薄壁不锈钢管（Light gauge stainless pipes）具有以下突出的优势：力学性能、超群的耐磨损性能、卫生性能好、良好的耐温性能、保温性能较好、内壁光滑水阻小；外表美观、清洁、时尚，可回收再利用；有利于节约水资源；使用范围广；使用寿命长综合成本低。
</p>
<p style="text-indent:2em;">
	1、 满足健康要求薄壁不锈钢管不会对水质造成二次污染，达到国家直接饮用水质标准的需要。
</p>
<p style="text-indent:2em;">
	2、可以回收利用
</p>
<p style="text-indent:2em;">
	薄壁不锈钢管是一种可以完全回收利用的水管；不会给子孙后代留下不可以处理的垃圾。
</p>
<p style="text-indent:2em;">
	3、节约水资源
</p>
<p style="text-indent:2em;">
	薄壁不锈钢管材料的强度高过了所有的水管材料，降低了水管受外力影响漏水的可能性，大量地节约了水资源。
</p>
<p style="text-indent:2em;">
	4、降低输送成本
</p>
<p style="text-indent:2em;">
	薄壁不锈钢管材地耐腐蚀性能优越，在长期地使用过程中不会结垢，内壁光洁如故，输送能耗低，节约成本。
</p>
<p style="text-indent:2em;">
	5、减少热能损失
</p>
<p style="text-indent:2em;">
	薄壁不锈钢管材料的保温性能是铜材料水管的24倍，大量地节约了热水输送中地热能损耗。
</p>
<p style="text-indent:2em;">
	6、避免洁具污染
</p>
<p style="text-indent:2em;">
	不会污染卫生洁具，避免了洁具上产生不可擦洗地“红印”和“蓝印”。
</p>
<p style="text-indent:2em;">
	国内薄壁不锈钢管是上世纪90年代末才问世的新型管材，通过新技术、新工艺，在确保使用功能的前提下，厚壁改成了薄壁。成本下降的薄壁不锈钢水管发展势头强劲，已大量应用于建筑给水和直饮水管道，建设部非常重视这一新型管材，薄壁不锈钢水管的行业标准已于2001年出台。
</p>
<p style="text-indent:2em;">
	用传统的焊接方式进行连接，因为不锈钢管在现场施工很难做到管内壁的氩气保护，保护不良的焊接会导致不锈钢抗腐蚀性能的大幅下降，其焊缝在二到三年后就会发生渗漏。若采用螺纹连接，钢管就得留有足够的套丝厚度，这样加大壁厚就会造成不必要的浪费，并且不锈钢管的套丝难度是普通钢管的几倍，安装极不方便。
</p>
<p style="text-indent:2em;">
	薄壁不锈钢管以其可靠、卫生环保、经济适用等到优点，也正在成为人们给水管材中新的选择。 可靠、卫生环保和经济使用一直是影响各类新型管材推广的三大因素。而薄壁不锈钢管几乎是这三大因素的结合者。不仅如此，其明亮光洁的外观正迎合了现代人追求高品味生活的需求。因此，它正在成为人们看好的新型管材之一。
