保温钢管分为力量大类: 1、低压流体输送聚氨酯保温钢管 2、中高压高温蒸汽钢套钢保温钢管。两者输送介质温度、压力有所差别。
1、聚氨酯保温管从里到外分三层结构:
一层:工作钢管层 根据设计和客户的要求一般选用无缝钢管、螺旋钢管和直缝钢管。钢管表面经过先进的抛丸除锈工艺处理后,钢管除锈等级可达GB8923-1988标准中的Sa2级,表面粗糙度可达GB6060.5-88标准中R=12.5微米。
第二层:聚氨酯保温层: 用高压发泡机在钢管与外护层之间形成的空腔中一次性注入硬质聚氨酯泡沫塑料原液而成,即俗称的“管中管发泡”。
第三层:高密度聚乙烯保护层: 预制成一定壁厚的黑色或黄色聚乙烯塑料管材。其作用一是保护聚氨酯保温层免遭机械硬物破坏,二是防腐、防水。

钢套钢保温管保温结构依据滑动方式不同分为:内滑动式与外滑动式
1、内滑动式:保温结构由工作钢管、硅酸铝、减阻层、微孔硅酸钙、隔热层、不锈钢紧固钢带、铝箔反射层、聚氨酯保温层、外套钢管、外防腐层组成。
2、外滑动式:保温结构由工作钢管、玻璃棉保温隔热层、铝箔反射层、不锈钢紧固带、滑动导向支架、空气保温层、外护钢管、外防腐层组成。

“保温钢管”它是一种在经过了保温工艺处理后形成了一种钢制管道。下面。小编为大家详细的介绍一下保温钢管的分类和其他相关内容。也希望通过小编的介绍,大家可以深入细致地了解保温钢管的知识,在了解它的同时也方便大家选择购买。

一、保温钢管的分类
1、钢套钢复合保温钢管
小编为大家介绍的是保温钢管的具体分类。首先,我们要说的是钢套钢复合保温钢管,它是一种可以埋在地下的管道,它可以在没有混泥土的情况下使用,这样就可以使我们在使用时降低了材料的成本,同时也可以缩短,我们在施工上使用的时间。钢套钢复合保温钢管如果按照保温结构的滑动形式不同可以分为内滑动式的和外滑动式的。
内滑动式的它的结构形式主要为可以用来输送介质的钢管,外套钢管,复合硅酸盐或者是微孔硅酸钙,还有硬质聚氨酯泡沫塑料和玻璃钢壳防腐保护层等等组成。这种内滑动式的保温钢管在一些保温处理技术上是非常可靠的。这主要是因为它的保温结构有减阻层,隔热层,外套钢管,外防腐层,铝箔反射层等等组成。
而外滑动式的保温钢管的结构形式主要是由内钢管,富锌底漆,滑动导向支架,耐高温玻璃棉,外套钢管,空气保温层,铝箔反射层,和外套钢管防腐层组成。
2、聚氨酯保温钢管
接下来,小编为大家介绍的是聚氨酯保温钢管,它的优点主要有:在使用它可以降低工程造价;聚氨酯保温钢管它的热损耗低,这就保证了它可以节约能源;第三个优点是它的防腐蚀性能比较好,绝缘性也是比较好的,另外它的使用寿命是很长的。
二、保温钢管的应用
保温钢管,它是比较适合使用在-50℃—150℃的温度内,同时它的应用也比较广泛,它可以适用在集中供暖,集中供冷,冷库,煤矿,或者是石油化工等行业。
关于保温钢管的分类和应用,小编就先简单的为大家介绍到这里,如果大家还想要了解更多相关的知识,或者是有关房屋装潢装修的问题,都可以注册土巴兔账号,关注土巴兔网站,这里小编会为大家尽全力解答各种问题。
