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，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。氣體管道施工公司氧氣管道應(yīng)盡量少設(shè)彎頭和分岔頭。</p><div
