螺旋管米重計算公式：(外徑-壁厚)*壁厚*0.0246615
螺旋管主要用于石油、天然氣的輸送管線，其規(guī)格用外徑*壁厚表示。螺旋管有單面焊的和雙面焊的，焊管應保證水壓試驗、焊縫的抗拉強度和冷彎性能符合規(guī)定。
螺旋管的常用標準一般分為:SY/T5037-2018(部標、也叫 普通流體輸送管道用螺旋縫埋弧焊鋼管)、GB/T9711.1-1997(國標、也叫石油天然氣工業(yè)輸送鋼管交貨技術(shù)條件第一部分：A級鋼管(要求嚴格的有GB/T9711.2 B級鋼管))、API-5L(美國石油協(xié)會、也叫管線鋼管;其中分為PSL1和PSL2兩個級別)、SY/T5040-92(樁用螺旋縫埋弧焊鋼管)。以下是螺旋管規(guī)格重量表：
