直埋式保温管的工艺流程和产品特点：
The technological process and product characteristics of directly buried insulating pipe:
直埋式保温管一种是由保送介质的直缝钢管、高密度聚乙烯外套管以及直缝钢管和外套管之间填充的聚氨酯硬泡保温层严密结合而成。
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.
直埋式保温管的制造只需将除锈防腐后的直缝钢管套在聚乙烯套管内，两头注入聚氨酯泡沫，使之充沛填满钢管与聚乙烯套管之间的空隙，终使螺旋钢管、套管、保温层构成一个结实的全体，到达防腐保温的效果;这种防腐保温方式可以架空或许埋在地下，整个施工进程均可在现场停止。
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.
工艺流程： 钢管检验-除锈防腐-穿管成型-封头修补-成品检验-成品堆放次要设备： 钢管缓冲平台、拨管机组、传动线、钢管预热炉、抛丸机主机 检验转台和不合格螺旋焊管前往传动线、快进滚轮组、牵引机、穿管机械、高压发炮机、修补平台、快出滚轮、检验平台等。
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.
产品特点：直埋式预制保温管较之传统的各类保温管材具有非常突出的优点：
Product features: Direct-buried prefabricated insulating pipes have outstanding advantages over traditional insulating pipes.
1、保温功能好，热损失仅爲传统管材的25%，临时运转可浪费少量动力，明显降低动力本钱。
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、具有很强的防水和耐腐蚀才能，不需附设管沟，可间接埋上天下或水中，施工简便迅速，综合造价低。
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、在高温条件下也具有良好的耐腐蚀和耐冲击性，可间接埋入冻土层。
3. It also has good corrosion resistance and impact resistance at high temperature, and can be buried in the frozen soil indirectly.
4、运用寿命可达30-50年，正确的装置和运用可使管网维修费用极低。
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、可设置报警零碎，自动监测管网渗漏毛病，精确指示毛病地位并自动报警。
5. It can set up alarm fragments, automatically monitor the leakage of pipeline network, accurately indicate the fault status and automatically alarm.
