知识业内对两个产品的叫法不一样,说是鳍片管的可能是从事这个行业比较久一点的人员,实质东西和结构没有太大区别。一般钢质的都是在无缝钢管上焊接而成。普遍认为螺旋鳍片管中的鳍片高度要比螺旋翅片管中的翅片要高一些(这个不是主要因素,翅片高度都是可以按客户要求定制的)。不过螺旋鳍片管相对的螺旋翅片管来说使用的环境比较恶劣,焊接工艺相对要严谨一些。话虽如此只是新产品整体型钢质螺旋翅片管大家还没有认识或者见识到,目前市场上基本都是理解成一个产品,只是需要从业人员知道就好了,便于服务客户。The term for the two products is different in the knowledge industry. It is said that the fin tube may be a person who has been engaged in the industry for a long time. The substance and structure are not very different. Ordinary steel is welded on seamless steel pipe. It is generally believed that the fin height in the spiral fin tube is higher than that in the spiral fin tube (this is not the main factor, fin height can be customized according to customer requirements). However, the spiral finned tube relative to the spiral finned tube for the use of the harsh environment, the welding process is relatively rigorous. That said, it is only a new product of integral steel spiral finned tube we have not yet known or seen, the current market is basically understood as a product, but the need for employees to know it, easy to serve customers.螺旋鳍片管和螺旋翅片管什么区别What is the difference between spiral finned tube and spiral finned tube?鳍片管和翅片管的主要作用就是增加受热面(或散热)、提高传热效率。The main function of finned tube and finned tube is to increase heating surface (or heat dissipation) and improve heat transfer efficiency.焊接强度和稳定性区别Difference between welding strength and stability1.1 拉脱力试验: 大于200MPa 或者钢管部分撕裂1.1 pull-out test: greater than 200MPa or partial tear of steel pipe.1.2焊缝宽度: 大于翅片厚度 即焊着率>99%1.3焊接强度稳定性: 每班首件做焊接试样 达到2.1 或者2.2的要求1.2 Weld Width: Thicker than Fin, i.e. Welding Rate > 99% 1.3 Welding Strength Stability: The first part of each shift to do welding specimens to meet the requirements of 2.1 or 2.21.4 焊缝抗弯曲试验: 翅片左右弯曲20度 向左向右弯曲两次 焊缝无裂纹1.4 weld bending test: fins bending about 20 degrees to left to right bend two times weld without crack.1.5 锤击试验: 平行于钢管敲击翅片上部 直到翅片脱落 翅片本身不得断裂1.5 hammer test: parallel to the top of the steel pipe beating the fins until the fins are detached, and the fins themselves must not be broken.1.6 如果试验失败 必须启用退火功能1.6 if the test fails, the annealing function must be enabled.热影响区区别Heat affected zone difference用显微镜配合微硬度计测量Measurement with microscope and micro hardness tester钢管热影响区深度小于0.5mmThe depth of heat affected zone of steel tube is less than 0.5mm产品尺寸精度区别Product size accuracy difference3.1 翅片段全长 -1mm ~ +1mm 分段运动精度 -0.5mm ~ +0.5mm3.1 wing segment full-length -1mm ~ +1mm segmented motion accuracy -0.5mm ~ +0.5mm3.2 片距 -0.2mm ~ +0.2mm3.2 slice distance -0.2mm ~ +0.2mm3.3 翅片和钢管垂直度 -1度 ~ +1度3.3 fin and steel tube perpendicularity -1 ~ +1 degrees3.4 同组对焊翅片平面度 -0.2mm ~ +0.2mm翅片本身厚度公差引起的高度差除外3.4 the same group of welding fins flatness -0.2mm ~ +0.2mm fin thickness tolerance caused by height difference except.3.5 同组对焊翅片高度差 -0.2mm ~ +0.2mm 翅片本身尺寸公差引起的高度差除外3.5 the height difference of the welding fin is the same as that of the -0.2mm group, except for the height difference caused by the size tolerance of the fin +0.2mm.3.6 双管中心距离公差 -0.5mm ~ +0.5mm3.6 double center distance tolerance -0.5mm ~ +0.5mm3.7在同样钢管材料, 同样片距和片数条件下, 不同翅片管焊接后长度变化一致3.7 under the same steel tube material, the length of the finned tubes will be changed after welding with the same chip spacing and number of sheets.焊接速度区别Difference of welding speed基管外径25~51 翅片厚度2mm 每对焊接时间小于3秒 (不包括上下料时间和退火时间)Welding time of each pair of fins with 25-51 outer diameter and 2 mm thickness is less than 3 seconds (excluding loading and unloading time and annealing time) 方管
