一、不鏽鋼矩形管的概述
不鏽鋼矩形管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。
二、不鏽鋼矩形管的分類
不鏽鋼矩形管可以分無縫鋼管和焊接鋼管(有縫管)兩大類。
三、不鏽鋼矩形管的耐壓能力和質量
對於承受流體壓力的不鏽鋼矩形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。
四、不鏽鋼矩形管的重量計算
a—矩形管的長,b—矩形管的寬,t—矩形管的壁厚,L—矩形管的長度,不鏽鋼的密度7.9
重量計算=[(a×b)-(a-t)×(b-t)]×L×7.9 (單位:千克)
