1020x12螺旋管樁理論重量|江蘇螺旋鋼管執(zhí)行標(biāo)準(zhǔn)
螺旋管及其標(biāo)準(zhǔn)分類
承壓流體輸送用螺旋縫埋弧焊鋼管SY5036-83主要用于輸送石油、天然氣的管線；承壓流體輸送用螺旋縫高頻焊鋼管SY5038-83，用高頻搭接焊法焊接的，用于承壓流體輸送的螺旋縫高頻焊鋼管。鋼管承壓能力強(qiáng)，塑性好，便于焊接和加工成型；一般低壓流體輸送用螺旋縫埋弧焊鋼管SY5037-83，采用雙面自動(dòng)埋弧焊或單面焊法制成的用于水、煤氣、空氣和蒸汽等一般低壓流體輸送用埋弧焊鋼管
現(xiàn)在螺旋鋼管的常用標(biāo)準(zhǔn)一般分為:SY/T5037-2000（部標(biāo)、也叫 普通流體輸送管道用螺旋縫埋弧焊鋼管）、GB/T9711.1-1997（國(guó)標(biāo)、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(jí)鋼管(到目前要求嚴(yán)格的有GB/T9711.2 B級(jí)鋼管)）、API-5L（美國(guó)石油協(xié)會(huì)、也叫管線鋼管；其中分為PSL1和PSL2兩個(gè)級(jí)別）、SY/T5040-92（樁用螺旋縫埋弧焊鋼管）
