講述聚氨酯保溫管的幾種固定形式：分為：1、內(nèi)滑動(dòng)外固定就是工作鋼管受熱膨脹時(shí)，鋼管運(yùn)動(dòng)，發(fā)生位移，而保溫結(jié)構(gòu)層與外套管成一整體結(jié)構(gòu)，不產(chǎn)生運(yùn)動(dòng)。外固定即工作鋼管和外保護(hù)管同時(shí)固定，在每一段管道和補(bǔ)償器的兩端，都要設(shè)兩個(gè)很大的鋼筋混凝土支墩，才能保證管道的固定。不設(shè)導(dǎo)向支架。外固定因?yàn)楸仨氃O(shè)鋼筋混凝土支墩，所以施工占地大、投資多、工期長(zhǎng)，而且支墩又是直埋保溫管道的薄弱部位，該部位易產(chǎn)生"熱橋"，也易出現(xiàn)滲水現(xiàn)象，管道運(yùn)行不正常時(shí)，該部位也易出現(xiàn)***。特別是對(duì)"鋼套鋼"保溫結(jié)構(gòu)，由于溫升引起的外鋼管熱應(yīng)力特別大，鋼筋混凝土支墩的尺寸也特別大，該部位也更易出現(xiàn)***。根據(jù)外護(hù)管的不同，又可分為塑套鋼結(jié)構(gòu)、玻璃鋼套鋼結(jié)構(gòu)和鋼套鋼結(jié)構(gòu)。經(jīng)過(guò)實(shí)踐證明，塑套鋼結(jié)構(gòu)已經(jīng)不適應(yīng)直埋蒸汽管道的特點(diǎn)，基本上被淘汰?！安Ａт撎卒摗北亟Y(jié)構(gòu)必須采取這種固定形式。2、內(nèi)滑動(dòng)內(nèi)固定就是將工作鋼管通過(guò)一定的結(jié)構(gòu)形式固定在外保護(hù)管上，充分利用外保護(hù)管的強(qiáng)度和剛度以及外保護(hù)管與土壤之間的摩擦力來(lái)使內(nèi)管固定，不用鋼筋混凝土結(jié)構(gòu)固定，可節(jié)省鋼筋混凝土支墩。只有以鋼管作為外保護(hù)管才可能采用內(nèi)固定形式。固定端有隔熱設(shè)施，以減少熱橋效應(yīng)。</p><div
