無縫鋼管是用鋼錠或?qū)嵭墓芘鹘?jīng)穿孔制成毛管，然后經(jīng)熱軋、冷軋或冷撥制成。無縫鋼管大量用作輸送流體的管道。鋼管與圓鋼等實(shí)心鋼材相比，在抗彎抗扭強(qiáng)度相同時(shí)，重量較輕，是一種經(jīng)濟(jì)截面鋼材，<span style="color:red;"><span style="color:red;">寬泛</span></span>用于制造結(jié)構(gòu)件和機(jī)械零件，如石油鉆桿、汽車傳動(dòng)軸、自行車架以及建筑施工中用的鋼腳手架等。無縫鋼管制造環(huán)形零件，可提高材料利用率，簡(jiǎn)化制造工序，節(jié)約材料和加工工時(shí)，如滾動(dòng)軸承套圈、千斤頂套等，目前已<span style="color:red;"><span style="color:red;">寬泛</span></span>用鋼管來制造。 </p> <p> 鋼管還是各種常規(guī)武器不可缺少的材料，炮筒等都要鋼管來制造。鋼管按橫截面積形狀的不同可分為圓管和異型管。由于在周長相等的條件下，圓面積較<span style="color:red;"><span style="color:red;">大</span></span>，用圓形管可以輸送更多的流體。此外，圓環(huán)截面在承受內(nèi)部或外部徑向壓力時(shí)，受力較均勻，因此，絕大多數(shù)鋼管是圓管。 </p> <p>

金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗(yàn)方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對(duì)于管材一般常用的有布氏、洛氏、維氏硬度三種。 </p> <p> A、布氏硬度（HB） </p> <p> 用一定直徑的鋼球或硬質(zhì)合金球，以規(guī)定的試驗(yàn)力（F）壓入式樣表面，經(jīng)規(guī)定保持時(shí)間后卸除試驗(yàn)力，測(cè)量試樣表面的壓痕直徑（L）。布氏硬度值是以試驗(yàn)力除以壓痕球形表面積所得的商。以HBS（鋼球）表示，單位為N/mm2（MPa）。 </p> <p> 其計(jì)算公式為： </p> <p> 式中：F--壓入金屬試樣表面的試驗(yàn)力，N； D--試驗(yàn)用鋼球直徑，mm； d--壓痕平均直徑，mm。 </p> <p> 測(cè)定布氏硬度較準(zhǔn)確可靠，但一般HBS只適用于450N/mm2（MPa）以下的金屬材料，對(duì)于較硬的鋼或較薄的板材不適用。在鋼管標(biāo)準(zhǔn)中，布氏硬度用途較廣，往往以壓痕直徑d來表示該材料的硬度，既直觀，又方便。 </p> <p> 舉例：120HBS10/1000/30：表示用直徑10mm鋼球在1000Kgf（9.807KN）試驗(yàn)力作用下，保持30s（秒）測(cè)得的布氏硬度值為120N/ mm2（MPa）。 </p> <p> <br /> 秦皇島消防**管大概多少錢</p><p
