直埋式保溫管的工藝流程和產(chǎn)品特點(diǎn)：
The technological process and product characteristics of directly buried insulating pipe:
直埋式保溫管一種是由保送介質(zhì)的直縫鋼管、高密度聚乙烯外套管以及直縫鋼管和外套管之間填充的聚氨酯硬泡保溫層嚴(yán)密結(jié)合而成。
The direct buried insulating pipe is a rigid polyurethane foam insulating layer filled between the straight seam steel pipe, the high density polyethylene outer sleeve and the straight seam steel pipe and the outer sleeve.
直埋式保溫管的制造只需將除銹防腐后的直縫鋼管套在聚乙烯套管內(nèi)，兩頭注入聚氨酯泡沫，使之充沛填滿(mǎn)鋼管與聚乙烯套管之間的空隙，終使螺旋鋼管、套管、保溫層構(gòu)成一個(gè)結(jié)實(shí)的全體，到達(dá)防腐保溫的效果;這種防腐保溫方式可以架空或許埋在地下，整個(gè)施工進(jìn)程均可在現(xiàn)場(chǎng)停止。
The manufacture of directly buried insulation pipes only needs to set the straight seam steel pipes after rust removal and corrosion protection in the polyethylene bushing, and the two ends are filled with polyurethane foam to fill the gap between the steel pipe and the polyethylene bushing so as to make the spiral steel pipe, casing and insulation layer form a sturdy whole so as to achieve the effect of anticorrosion and heat preservation. The construction process can be stopped on site.
工藝流程： 鋼管檢驗(yàn)-除銹防腐-穿管成型-封頭修補(bǔ)-成品檢驗(yàn)-成品堆放次要設(shè)備： 鋼管緩沖平臺(tái)、撥管機(jī)組、傳動(dòng)線、鋼管預(yù)熱爐、拋丸機(jī)主機(jī) 檢驗(yàn)轉(zhuǎn)臺(tái)和不合格螺旋焊管前往傳動(dòng)線、快進(jìn)滾輪組、牽引機(jī)、穿管機(jī)械、高壓發(fā)炮機(jī)、修補(bǔ)平臺(tái)、快出滾輪、檢驗(yàn)平臺(tái)等。
Technological process: steel tube inspection - rust removal and anticorrosion - pipe piercing forming - head repair - finished product inspection - finished product stacking secondary equipment: steel tube buffer platform, pipe diverting unit, transmission line, steel tube preheating furnace, shot blasting machine main machine inspection turntable and unqualified spiral welded pipe to transmission line, fast-forward roller set, tractor, pipe piercing machinery, high-pressure gun launcher, repair platform, Fast-out roller, inspection level Taiwan and so on.
產(chǎn)品特點(diǎn)：直埋式預(yù)制保溫管較之傳統(tǒng)的各類(lèi)保溫管材具有非常突出的優(yōu)點(diǎn)：
Product features: Direct-buried prefabricated insulating pipes have outstanding advantages over traditional insulating pipes.
1、保溫功能好，熱損失僅爲(wèi)傳統(tǒng)管材的25%，臨時(shí)運(yùn)轉(zhuǎn)可浪費(fèi)少量動(dòng)力，明顯降低動(dòng)力本錢(qián)。
1. Good thermal insulation function, heat loss is only 25% of the traditional pipe, temporary operation can waste a small amount of power, significantly reducing power costs.
2、具有很強(qiáng)的防水和耐腐蝕才能，不需附設(shè)管溝，可間接埋上天下或水中，施工簡(jiǎn)便迅速，綜合造價(jià)低。
2. It has strong ability of waterproofing and corrosion resistance. It can be buried in the world or water indirectly without additional pipe trenches. It is simple and quick to construct, and its comprehensive cost is low.
3、在高溫條件下也具有良好的耐腐蝕和耐沖擊性，可間接埋入凍土層。
3. It also has good corrosion resistance and impact resistance at high temperature, and can be buried in the frozen soil indirectly.
4、運(yùn)用壽命可達(dá)30-50年，正確的裝置和運(yùn)用可使管網(wǎng)維修費(fèi)用極低。
4. The service life can reach 30-50 years. Correct installation and operation can make the maintenance cost of the pipeline network very low.
5、可設(shè)置報(bào)警零碎，自動(dòng)監(jiān)測(cè)管網(wǎng)滲漏毛病，精確指示毛病地位并自動(dòng)報(bào)警。
5. It can set up alarm fragments, automatically monitor the leakage of pipeline network, accurately indicate the fault status and automatically alarm.
