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(lái)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 /> 唐山焊管比較便宜螺紋管的加工方法一般有絞紋法、滾壓法、擠壓法和軋制法。</p><div style="width:100%;text-align: center;"><img

鍍鋅管，也稱為鍍鋅鋼管，分為熱浸鍍鋅和電鍍鋅。熱浸鍍鋅層厚，涂層均勻，附著力強(qiáng)，使用壽命長(zhǎng)。電鍍成本低，表面不光滑，耐腐蝕性比熱浸鍍鋅管差。鍍鋅鋼管：熱鍍鋅鋼管鋼管基板與熔融電鍍液復(fù)合物理、發(fā)生化學(xué)反應(yīng)，形成致密的鋅鐵合金層耐腐蝕結(jié)構(gòu)。合金層與純鋅層、鋼管襯底集成在一起。因此，其耐腐蝕性強(qiáng)。<br /> 鍍鋅鋼管：冷鍍鋅鋼管鋅層是電鍍層，鋅層與鋼管基板分開分層。鋅層很薄，鋅層簡(jiǎn)單地附著在鋼管基板上，很容易脫落。因此，其耐腐蝕性差。在新家中，禁止使用冷鍍鋅鋼管作為供水管。</pstyle="margin:0px;padding:0px;color:#666666;text-transform:none;text-indent:0px;letter-spacing:normal;font-family:微軟雅黑;font-size:14px;font-style:normal;font-weight:400;word-spacing:0px;white-space:normal;orphans:2;widows:2;background-color:#ffffff;font-variant-ligatures:normal;font-variant-caps:normal;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;">
