class="khcont">以ψ表示，單位為%。計(jì)算公式如下：式中：S0--試樣原始橫截面積，mm2；S1--試樣拉斷后縮徑處的少橫截面積，mm2。硬度指標(biāo)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。A、布氏硬度（HB）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)。其計(jì)算公式為：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。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，布氏硬度用途廣，往往以壓痕直徑d來(lái)表示該材料的硬度，既直觀，又方便。

class="khcont">今天給大家介紹無(wú)縫鋼管和焊管的區(qū)別到底在哪里？首先：主要的就是他們的成型工藝不同。普通的鋼管，比如自來(lái)水水管，一般是通過(guò)將平板材經(jīng)折彎后焊接起來(lái)的，這種工藝比較簡(jiǎn)單粗糙，成品加工后可以在上面發(fā)現(xiàn)一條焊縫。而無(wú)縫鋼管一般是將熔融狀態(tài)的鋼水通過(guò)環(huán)形狹縫積壓出來(lái)后再經(jīng)拉伸等處理工藝成型，在這種工藝下就沒(méi)有焊縫。在性能上，無(wú)縫鋼管在承壓能力上較普通鋼管有很大提高，所以經(jīng)常被用于高壓設(shè)備使用。如液壓設(shè)備的管路連接等。而普通鋼管的焊縫部位是其薄弱環(huán)節(jié)，焊縫質(zhì)量也是影響其整體性能的主要因素。對(duì)現(xiàn)在的人們來(lái)說(shuō)，無(wú)縫鋼管很是熟悉。因?yàn)樗诟鱾€(gè)領(lǐng)域都起著舉足輕重的作用。我們中國(guó)的無(wú)縫鋼管在1953年10月27日，根無(wú)縫鋼管試軋成功，這也是1953年我國(guó)重工業(yè)發(fā)展中的巨大事件。或許，無(wú)縫鋼管并不是什么高科技產(chǎn)品，但正是因?yàn)橛辛怂庞辛宋覀兊墓I(yè)的發(fā)展。無(wú)縫鋼管作為輸送管運(yùn)輸著油、氣體、水源等各個(gè)流體。它就像我們?nèi)梭w的血管一樣，為我們的祖國(guó)大地不斷的運(yùn)輸和分配著各個(gè)能源的合理利用。
