搪瓷管的工作温度对自身使用的影响
为了能让大家更多的了解搪瓷管，下面给大家介绍搪瓷管的工作温度对自身使用的影响：
In order to let you know more about enamel pipe, the following to ioduce the work temperature of enamel pipe for their use:
搪瓷管经900℃高温焙烧，冷却后搪瓷与钢板粘结在一起。由于搪瓷的线膨胀系数和延伸率小于钢板，因此冷却后搪玻璃的变形量小于钢板的变形量，搪瓷受到钢板的约束产生压应力。搪瓷管制成后，其搪玻璃即存在预压缩应力，而钢板则存在预拉伸应力。
Enamel tubes were calcined at high temperature after 900, and the cooling was bonded with the steel plate. Because the enamel linear expansion coefficient and extension rate is less than the steel, so cooling after deformation of the glass lined ***aller than that of the plate deformation, enamel is compressive stress caused by plate c***traint. After the cool of enamel, glass lining is pre compressive stress, and the steel plate are pre tensile stress.
由于预应力与线膨胀系数和延伸率相关，线膨胀系数和延伸率与温度又密切相关，因此搪瓷管的工作温度对搪瓷管的使用影响很大。如果因温度变化大而使搪瓷产生的应力超过其使用应力，搪瓷将被***。
As the prestressing force is related to linear expansion coefficient and elongation coefficient, linear expansion coefficient and extension rate are closely related to the temperature. Enamel will be destroyed if the temperature changes greatly and the stress of the enamel is more than that of its use.
因此搪瓷管搪瓷层遇冷、热急变，极***瓷。因此搪瓷管有耐温限制：温度 200℃，耐温急变：冷冲击lt;1IO~C，热冲击lt;120℃。考虑到钢市自身供需面未有改观，估计下周不锈钢板价格依旧弱势调整为主。投料时物料温度与罐体温差太大以及升温时蒸汽过猛、降温太急也能导致爆瓷。因此搪瓷管在使用中升、降温要缓慢、均匀，分级冷却。
Therefore, the enamel enamel pipe cold hot blast, highly explosive porcelain. The enamel pipe with temperature resistant limit: 200 degrees Celsius temperature, high temperature blast: cold shock lt;1IO~C, heat shock lt;120 C. The temperature of the material and the tank temperature difference of the feed is too high and the heating steam, excessive cooling too quickly can also lead to explosive porcelain. Therefore, in the use of enamel pipe or slow cooling, uniform cooling, grading.

搪瓷管的使用性能受温度影响
搪瓷管经过高温焙烧、冷却后，搪瓷与钢板就粘结在了一起。对生产的搪瓷波纹管进行试验证明，如果搪瓷波纹管按上述规范工作，它的便用寿命基本土可达到5万次左右。由于搪瓷的线膨胀系数和延伸率小于钢板的特性，冷却后搪玻璃的变形量会小于钢板的变形量，而搪瓷受到钢板的约束就会产生压应力。也就是说搪瓷管制成后，搪玻璃会存在一种预压缩应力，而钢板则存在预拉伸应力。
Enamel tube through the high temperature roasting, cooling, enamel and steel plate is bonded together. Because the characteristics of enamel of the coefficient of linear expansion and extension rate is less than the plate, deformation after cooling glass lining will be less than the amount of deformation of steel, and steel plate enamel c***trained will generate compressive stress. That is to say the enamel tube, glass lined there will be a pre compressive stress, and the steel plate are pre tensile stress.
由于预应力与线膨胀系数和延伸率相关，而线膨胀系数、延伸率又与温度密切相关，因此搪瓷管的工作温度对瓷管本身的使用会带来很大的影响。Theenamelpipewithtemperatureresistantlimit:200degreesCelsiustemperature,hightemperatureblast:coldshocklt。在这里需要注意温度的变化，如果温度变化大，很容易使搪瓷产生的应力超过使用应力，从而引起搪瓷的***，一旦搪瓷层遇到冷、热急变，极易发生爆瓷现象。
Due to prestressing force and the coefficient of linear expansion and extension rate, and the coefficient of linear expansion, elongation and closely related with the temperature, so the enamel pipe working temperature on the porcelain tube itself use will h***e a great impact. Here we need to pay attention to the change of temperature, if the temperature change is big, easy to cause the enamel of stress over the use of stress, so as to cause enamel damage, once the enamel layer encountered cold and hot blast, prone to burst phenomenon of porcelain.
空气预热器的概述
HINO-PILE空气预热器，体积小，特殊高性能。由于放热和受热流体沿传热面紊流流动，热交换性能非常。是代替以前的蛇形管式、翅片管式、多管式、二重管式、套筒式、螺旋式、平板式及蓄热式热交换器的新一代***率产品。
1、应用范围广，机能多样
气体-气体，气体-液体，液体-液体的加热、冷却、冷凝、蒸发等各种形式的热交换方法。
活跃在产业机械、矿山、建筑、电力、汽车、化学、食品等各个工业分布中。
2、长久维持高性能
流体通路呈蛇形或菱形。单板表面流体的层流部分产生脱离运动，流体加大紊流度。两流体同时激烈的新陈代谢获得高传热系数。而且由于脱离运动，尘土、渣屑、杂质不易附着，故可维持长久的高性能。
3、小型化成功
蛇形通道-列，连续、密闭、相互层叠的构造，与管间相隔的多管式构造相比，同一容积的传热面积增加数倍。由于总传热系数大，所需传热面积减小，热交换器实现了小型化。
4、流动阻力小
由于传热性能，流体通过的距离缩短，而且单板（间隔）可根据对压力损失的要求自由调整。
5、优良的耐压性
单板间波形的顶点相互接触，根据外框的设计抗压能力可以自由选择。
6、易保修
没有驱动部件，维修频度少。炭灰、尘土、渣屑、杂物等附着物可用刷子、化学剂、喷射等方法清洗。构造简单。
7、优良的耐热性
材料为耐热钢，经溶接组装，单元波形曲板对热膨胀差耐性极强。
