style="text-indent:25px">管道安裝須注意壓力：工程上所指壓力是指物體單位面積所受壓力，物理學(xué)中稱壓強(qiáng)。一般我們熱力工程所指公稱壓力是指物體所能承受的工作壓力，通常指相對(duì)壓力（表壓力），單位為工程大氣壓。相對(duì)大氣壓是指超出大氣壓的數(shù)值，以符號(hào)P來表示。大氣壓是指以真空為基準(zhǔn)，以真空起算，等于表壓力加上大氣壓力。1個(gè)標(biāo)準(zhǔn)大氣壓力（物理大氣壓）=1.033kg/cm2=760mmhg,為了工程上計(jì)算方便，規(guī)定一個(gè)工程大氣壓為1kg/cm2或735.6mmhg和10m水柱?，F(xiàn)我國(guó)壓力計(jì)量單位已改Mpa。1Mpa=10.2kg/cm2、10kg/cm2=0.98Mpa。流量：指在單位時(shí)間內(nèi)流過管道或其它容器有效斷面流體量。有重量流量和體積流量，單位分別為T/小時(shí)或m3/h，用符號(hào)Q表示。溫度：指物體受熱程度的量。溫度只能從高傳到低，溫度計(jì)量單位有華氏、攝氏三種。攝氏溫標(biāo)以水冰點(diǎn)為0℃，沸點(diǎn)為100℃。華氏溫標(biāo)水冰點(diǎn)為32°F，沸點(diǎn)為212°F；溫度是水冰點(diǎn)為～273℃，它高于攝氏溫標(biāo)273°，用字母T表示。我們一般所用溫度表示都采用攝氏溫標(biāo)，用字母t表示。廣州潔凈工藝管道施工工程</p></p><br
