U型弯管 
U-管換熱器是由折流板和U型管束裝配在管殼中共同構成,為管殼式(列管式)換熱器一種,U形管束大大的增強了換熱面積和效率,高性能的U形管是確保設備正常運作的前提條件,高性能U形管對彎管設備提出了極高的要求,羅德鋼鐵通過CNC數控彎管系統,對管子的彎管半徑,減壁量以及圓度進行控制,並且在彎管后做去應力退火(以確保去除冷加工應力殘餘),做100%水壓試驗,出具彎管報告。 



彎曲半徑: 1.5*OD(外徑)~1500毫米
當訂單要求管子的最小彎曲半徑小於1.5倍外徑時,必須和生產商協商一致。
直管生產最長長度(彎管前):35米
單腿長長度範圍: 最短1米,最長16.5米
注意:其他尺寸需要和生產商協商一致。
熱處理:彎管後進行去應力退火(彎管處加兩邊腿長的300毫米處)
包裝: 採用根據不同規格,彎曲半徑等設計的,薰蒸過的,適合海運運輸,牢固的實木木箱包裝,整管加套塑料薄膜,管端戴帽套,如客戶訂單內有特殊要求,嚴格恪守。
1.100% PMI檢測/SPECTRO 化學成分分析
2.100%尺寸檢驗&100%表面檢測
3.拉伸實驗,卷邊實驗,硬度試驗,反向壓扁實驗
4.彎管後100%水壓測試加100%無損檢測
5.
根據客戶要求,檢查每隻U形管彎管後彎管處是否進行去應力退火,並提交彎管報告

注意: 所有檢測都需根據標準和測試結果提供檢測報告

 
1.直線度測試
2.粗糙度測試
3.晶相分析
4.晶腐實驗
5.低溫衝擊實驗
6 .形管通球實驗
7.彎管處滲透實驗
a.材質單(根據EN10204/3.1或者EN10204 3.2要求提供材料檢測證書)
b.原材料質保書
c.根據標準和訂單要求的所有其他檢測報告
d. 熱處理報告
e.裝運前的裝運通知
f.質量保證函
g.彎管報告
h.彎管後熱處理報告
