鋼套鋼保溫管由于外層的支撐鋼管采用焊接方式連接，所以其密閉性能十分優(yōu)異，而且外護(hù)層鋼管的堅固性、可靠性保證了熱網(wǎng)在高濕度地區(qū)的正常運(yùn)行。保溫管在安裝時是有嚴(yán)格的技術(shù)規(guī)范要求的，必須要參照相應(yīng)設(shè)計技術(shù)規(guī)范執(zhí)行。 </p> <p> 鋼套鋼保溫管的安裝要求：首先按照設(shè)計圖紙的要求，驗收管段質(zhì)量，仔細(xì)核對設(shè)計材料和各部位的幾何尺寸，充分考慮管段預(yù)留的位置和段的吊裝措施，熱力管道上放空和放凈開孔均應(yīng)在地面時完成，管線在吊裝之前應(yīng)完成管道管托的焊接工作并完成管道及管托的油漆工作。江蘇埋地式鋼套鋼鋼套鋼的內(nèi)滑動保溫層的保溫結(jié)構(gòu)的優(yōu)點是：保溫密封性好，無支架熱橋，有非常好的保溫效果。</p><div

彎頭、三通和疏水節(jié)是焊接在管道上面，且焊縫的外觀及質(zhì)量不應(yīng)低于GB50236-2011規(guī)定的二級質(zhì)量。 </p> <p> 焊接完成后需要進(jìn)行無損檢測，使用射線探傷和超聲波探傷，檢查管道焊縫的質(zhì)量。對于公稱壁厚小于或等于6mm的焊接三遍，其角焊縫無法進(jìn)行射線或超聲波探傷時，可采用水壓檢測及著色探傷進(jìn)行替代，著色探傷不應(yīng)低于丨級質(zhì)量。 </p><p> 鋼套鋼采用防水型保溫結(jié)構(gòu)，在外滑動型保溫結(jié)構(gòu)的基礎(chǔ)上在保溫層外增加防水層，使工作管和保溫層完全密閉;該結(jié)構(gòu)的優(yōu)點是不懼外套管進(jìn)水，避免因極端天造成地面積水進(jìn)入鋼套管保溫管內(nèi)使保溫層遭破壞失效。 </p> <p> 同時寧波萬里管道有限公司生產(chǎn)的保溫管具有含疏水節(jié)的彎頭，引導(dǎo)流體在芯管內(nèi)改變既定流動方向且排除地管中由于施工或液化現(xiàn)象產(chǎn)生積水的管件。保溫管的鋼套管上的排潮管既能及時排出潮濕氣體，又可作為日常運(yùn)行的報警信號管。鋼套鋼為什么需要防腐。</p><div style="width:100%;text-align:
