U型弯管 
U-管换热器是由折流板和U型管束装配在管壳中共同构成,为管壳式(列管式)换热器一种,U形管束大大的增强了换热面积和效率,高性能的U形管是确保设备正常运作的前提条件,高性能U形管对弯管设备提出了极高的要求,罗德钢铁通过CNC数控弯管系统,对管子的弯管半径,减壁量以及圆度进行控制,并且在弯管后做去应力退火(以确保去除冷加工应力残余),做100%水压试验,出具弯管报告



弯曲半径: 1.5*OD(外径)~1500毫米
当订单要求管子的最小弯曲半径小于1.5倍外径时,必须和生产商协商一致。
直管生产最长长度(弯管前):35米
单腿长长度范围: 最短1米,最长16.5米
注意:其它尺寸需要和生产商协商一致。
热处理:弯管后进行去应力退火(弯管处加两边腿长的300毫米处)
包装: 采用根据不同规格,弯曲半径等设计的,熏蒸过的,适合海运运输,牢固的实木木箱包装,整管加套塑料薄膜,管端戴帽套,如客户订单内有特殊要求,严格恪守。
1.100% PMI检测/SPECTRO 化学成分分析
2.100%尺寸检验&100%表面检测
3.拉伸实验,卷边实验,硬度试验,反向压扁实验
4.弯管后100%水压测试加100%无损检测
5.
根据客户要求,检查每只U形管弯管后弯管处是否进行去应力退火,并提交弯管报告

注意: 所有检测都需根据标准和测试结果提供检测报告

 
1.直线度测试
2.粗糙度测试
3.晶相分析
4.晶腐实验
5.低温冲击实验
6 .形管通球实验
7.弯管处渗透实验
a.材质单(根据EN10204/3.1或者EN10204 3.2要求提供材料检测证书)
b.原材料质保书
c.根据标准和订单要求的所有其它检测报告
d. 热处理报告
e.装运前的装运通知
f.质量保证函
g.弯管报告
h.弯管后热处理报告
