不鏽鋼無縫鋼

不鏽鋼管材的概念

   不鏽鋼管材是一種中空的長條鋼材,大量用作輸送流體的管道,如石油、天燃氣、水、煤氣、蒸氣等,另外,在搞彎、抗扭強度相同時,重量較輕,所以也廣泛用於製造機械零件和工程結構。也常用作生產各種常規武器、槍管、炮彈等。

    分類:鋼管分無縫鋼管和焊接鋼管(有縫管)兩大類。按斷麵形狀又可分為圓管和異形管,廣泛應用的是圓形鋼管,但也有一些方形、矩形、半圓形、六角形、等邊三角形、八角形等異形鋼管。
    對於承受流體壓力的鋼管都要進行液壓試驗來檢驗其耐壓能力和質量,在規定的壓力下不發生泄漏、浸濕或膨脹為合格,有些鋼管還要根據標準或需方要求進行卷邊試驗、擴口試驗、壓扁試驗等。

無縫不鏽鋼管材也稱不鏽鋼無縫管,是用鋼錠或實心管坯經穿孔製成毛管,然後經熱軋、冷軋或冷撥製成。無縫鋼管的規格用外徑*壁厚毫米數表示。

規格及外觀質量 

1、規格:熱軋管外徑32630mm。壁厚2.575mm。冷軋(冷拔)管外徑5200mm。壁厚2.512mm

2、外觀質量:鋼管的內外表麵不得有裂縫、折疊、軋折、離層、發紋和結疤缺陷存在。這些缺陷應完全**掉,**後不得使壁厚和外徑超過負偏差。

3、鋼管的兩端應切成直角,並**毛刺。壁厚大於20mm的鋼管允許氣割和熱鋸切割。經供需雙方協議也可不切頭。

4、冷拔或冷軋精密無縫鋼管《表麵質量》參照GB3639-83

無縫管工藝流程 

管坯——檢驗——剝皮——檢驗——加熱——穿孔——酸洗——修磨——潤滑風幹——焊頭——冷拔——固溶處理——酸洗——酸洗鈍化——檢驗——冷軋——去油——切頭——風幹——內拋光——外拋光——檢驗——標識——成品包裝

包裝

GB2102-88規定。鋼管包裝分三種:捆紮、裝箱、塗油捆紮或塗油裝箱。
