style="text-indent:25px">氣體管道安裝的注意事項(xiàng)1、管道連接時(shí)，嚴(yán)禁強(qiáng)力對(duì)口。管子與設(shè)備的連接，應(yīng)在設(shè)備安裝定位緊好地腳螺栓后自然地進(jìn)行。2、管道安裝若采用組合方式時(shí)，組合件應(yīng)具備足夠剛性，吊裝后不應(yīng)產(chǎn)生變形，臨時(shí)固定應(yīng)牢固可靠。3、在管線上因安裝儀表插座、疏水管座等需開孔、且孔徑小于30mm時(shí)，不得用氣割開孔。4、管道安裝時(shí)，注意管子與管子之間應(yīng)有一定的間距，相互不得接觸，也不得與基礎(chǔ)或設(shè)備之任何零件相碰，并應(yīng)留有足夠的距離，留作管道膨脹及敷設(shè)保溫材料之用。5、根據(jù)設(shè)計(jì)圖紙?jiān)诠艿郎蠎?yīng)開的孔洞，宜在管子安裝前開好。開孔后須將管道內(nèi)部清理干凈，不得遺留鉆屑或其它雜物，嚴(yán)禁汽割及角向磨光機(jī)進(jìn)行開孔。6、對(duì)于大直徑焊接鋼管，管子對(duì)口時(shí)，應(yīng)保證其縱向焊縫相互錯(cuò)開不少于100mm，并宜處于容易檢查的部位。7、支吊架安裝工作宜與管道的安裝工作同步進(jìn)行。支吊架的形式和安裝位置須嚴(yán)格遵照設(shè)計(jì)規(guī)定。管道的支吊架可參照國(guó)標(biāo)05R417-1中的各種形式并結(jié)合現(xiàn)場(chǎng)情況制作安裝。</p><p style="text-indent:25px">氧氣管道安裝：管道連接。采用焊接時(shí)，碳素鋼管施焊的首層用氬弧焊，其他各層用電弧焊。鋁銅管焊接多用氬弧焊。焊縫采用無損探傷抽查。用法蘭連接時(shí)，法蘭焊口處需作著色檢查。為了導(dǎo)出靜電，管道法蘭連接處要加焊導(dǎo)電片，一般用銅片或扁鋼，兩端與管道焊接的長(zhǎng)度應(yīng)大于50mm，并按設(shè)計(jì)要求做好靜電接地裝置。法蘭連接處的墊片一般用退火軟化的鋁片或銅片，安裝法蘭、閥件等用的工具應(yīng)經(jīng)過脫脂處理。試壓管道安裝完畢后，按設(shè)計(jì)要求進(jìn)行系統(tǒng)的強(qiáng)度試驗(yàn)和嚴(yán)密性試驗(yàn)。試驗(yàn)介質(zhì)可采用無油干燥的空氣、氮?dú)饣驘o油清水，以采用氣體介質(zhì)的較多。當(dāng)設(shè)計(jì)對(duì)試驗(yàn)壓力未作規(guī)定時(shí)，可取工作壓力的1.25倍作強(qiáng)度試驗(yàn)壓力，壓力應(yīng)逐級(jí)緩升，升到強(qiáng)度試驗(yàn)壓力值后持續(xù)10min，以無變形、無泄漏為合格。然后降至工作壓力作嚴(yán)密性試驗(yàn)，用涂肥皂水等方法進(jìn)行檢查，以無泄漏和恒壓半小時(shí)壓力不降為合格。按法蘭與管子的連接方式分為以下五種基本類型：螺紋法蘭、平焊法蘭、對(duì)焊法蘭、承插焊法蘭、松套法蘭。</p><div

style="text-indent:25px">氣體管道的管道如不能自由地伸縮，就會(huì)產(chǎn)生巨大的附加應(yīng)力。因此，在溫度變化較大的管道和需要有自由位移的常溫管道上，需要設(shè)置膨脹節(jié)，使管道的伸縮得到補(bǔ)償而消除附加應(yīng)力的影響。對(duì)于蒸汽管道、高溫管道、低溫管道以及有防燙、防凍要求的管道，需要用保溫材料包覆在管道外面，防止管內(nèi)熱(冷)量的損失或產(chǎn)生凍結(jié)。常用的保溫材料有水泥珍珠巖、玻璃棉、巖棉和石棉硅藻土等。管子、管子聯(lián)接件、閥門和設(shè) 備上的進(jìn)出接管間的聯(lián)接方法，由氣體的性質(zhì)、壓力和溫度以及管子的材質(zhì)、尺寸和安裝場(chǎng)所等因素決定，主要有螺紋聯(lián)接、法蘭聯(lián)接、承插聯(lián)接和焊接等四種方法。蒸汽管道分為兩種工作狀態(tài)，一個(gè)溫度高，一個(gè)近似于環(huán)境溫度，在冷熱交替變換中，會(huì)因?yàn)闊崦浝淇s原理而產(chǎn)生位移和受力，管道越長(zhǎng)，位移和受到的力越大，為了防止管道發(fā)生損壞，需要采取措施進(jìn)行規(guī)避，于是就有了這個(gè)彎，也被稱作為“膨脹節(jié)”，是用來吸收管子軸向膨脹位移的，也有躲避混凝土梁柱的要求，一舉兩得。邊臺(tái)的氣體管路隱藏在實(shí)驗(yàn)工作臺(tái)后面服務(wù)通道內(nèi)。壓力管道安裝</p><p
