適合國標螺旋鋼管的工程項目有哪些

日期:2020-04-20

國標螺旋鋼管主要由熱軋卷和中厚板制成。國標螺旋鋼管采用雙面埋弧焊技術。國標螺旋鋼管的壁厚略厚于普通國標螺旋鋼管。

國標螺旋鋼管

與普通壁厚國標螺旋鋼管相比,國標螺旋鋼管具有抗壓強度高、沖擊強度高、安全性能高、使用壽命長的優點。根據目前國內外市場需求,主要應用于以下行業領域:

1.工程結構。該行業主要采用中低端國標螺旋鋼管,如火車站、地鐵、體育場等大型管桁架工程。目前,國家尚未頒布結構用國標螺旋鋼管的相關實施標準。目前,國家標準/T3091-2008已普遍實施。

2.機加工。行業對大直徑直縫鋼管的平直度和不圓度有較高的要求,如使用道路機械和化工設備。

3.石油天然氣管道主要采用國標螺旋鋼管,如西氣東輸工程,一般執行國標GB/T9711-2011 PSL1。
