style="text-indent:25px">不銹鋼無縫管由整塊金屬制成的，表面上沒有接縫的鋼管，稱為無縫鋼管。根據(jù)生產(chǎn)方法，不銹鋼無縫管分熱軋管、冷軋管、冷拔管、擠壓管、頂管等。按照斷面形狀，不銹鋼無縫鋼管分圓形和異形兩種，異形管有方形、橢圓形、三角形、六角形、瓜子形、星形、帶翅管多種復(fù)雜形狀。較大直徑達(dá)650mm，較小直徑為0.3mm。根據(jù)用途不同，有厚壁管和薄壁管。無縫鋼管主要用做石油地質(zhì)鉆探管、石油化工用的裂化管、鍋爐管、軸承管以及汽車、拖拉機(jī)、航空用高精度結(jié)構(gòu)鋼管。不銹鋼無縫管檢測的辦法有什么呢？重慶不銹鋼管道無縫鋼管</p><p
