镀锌铁皮聚氨酯保温钢管主要由四部分组成。工作钢管:依照输送介质的技术要求，分别采用直缝钢管，无缝钢管和双面埋弧螺旋焊管。绝缘层:硬质聚氨酯泡沫塑料。防护壳:高密度聚乙烯或玻璃纤维。渗漏报警线:出产高温，预制直埋刚到钢管保温隔热管，嵌入同一个警戒线，但凡管道泄漏的地方，通过报警线的传导，可以在适用检测仪器报警，精确定位，泄漏程度大小的泄漏，在为了通知维修人员迅速处理漏水的管段，保证供热管网的运行.
Galvanized iron polyurethane insulating steel pipe is mainly composed of four parts. Working steel pipe: According to the technical requirements of the medium, straight seam steel pipe, seamless steel pipe and double-sided submerged arc spiral welded pipe are used respectively. Insulation layer: rigid polyurethane foam. Shell: High density polyethylene or glass fiber. Leakage alarm line: production high temperature, prefabricated directly buried to the steel pipe insulation pipe, embedded in the same warning line, but where the pipeline leakage, through the transmission of the warning line, can be applied to detect instrument alarm, accurate positioning, leakage degree of leakage, in order to inform maintenance personnel to quickly deal with the leakage of the pipeline section, to protect. Safe operation of heat supply pipeline network.
1、聚氨酯灌注时，施工环境温度宜为10-40℃，相对湿度应小于80%。
1. When polyurethane is poured, the construction environment temperature should be 10-40 C and the relative humidity should be less than 80%.
2、灌注后的硬泡聚氨酯保温层应充分熟化后，再进行下道工序的施工。
2. The rigid foam polyurethane insulation layer after filling should be fully ripened before the construction of the next process.
3、灌注后的硬泡聚氨酯保温层表面应当光滑，无明显凹陷突出。勤奋不是天生就有的，而是后天自己养成的。产生勤奋的原因有多种，有的是心怀抱负和信念，也有的是因为某种原因或在某事上受挫，从而勤勉起来。但是，只要勤于工作，就会有成功的必然。保温管保温管是绝热管道的简称，保温管用于液体、气体及其他介质的输送，在石油、化工、航天、军shi、集中供热热、空调、市政等等管道的绝热保温工程。
3. The surface of rigid foam polyurethane insulation layer after filling should be smooth without obvious depression and prominence. Diligence is not innate, but acquired by oneself. There are many reasons for diligence, some are ambition and belief, others are because of some reason or frustration in something, so diligence. However, as long as we are diligent in our work, there will be a certainty of success. Insulation pipes are abbreviated as insulating pipes. They are used for the transportation of liquid, gas and other media. They are used in the insulation projects of petroleum, chemical, aerospace, military shi, central heating, air conditioning, municipal and other pipes.
施工应注意的事项：
Notices to be paid attention to in construction:
1、施工时应避免地下水及雨水的浸泡，若端头不慎浸水，连接外套前应做干燥处理。
1. The soaking of groundwater and rainwater should be avoided during construction. If the end is immersed inadvertently, drying treatment should be done before connecting the jacket.
2、管材应储存在平整的场地，整齐码放，码放高度应小于1.5米。
2. Pipes should be stored in a flat site, neatly coded, and the coded height should be less than 1.5 meters.
3、管材吊装在轻装轻放，禁碰撞、抛掷，禁用钢丝绳直吊管身。
3. Pipe hoisting is light and light, collision and throwing are forbidden, and pipe body is forbidden to be hoisted by wire rope.
4、保温层及防腐层应避免火焰直接接触。现场安装请按下列程序：管沟开挖--基底处理（排水、垫砂）－下管--钢管焊接－检验（水压）－安装（试压）－发泡－封发泡孔。接头安装?公司可以派遣人员到工程现场进行接头的保温工作，包括接头外套管的安装、接头外套管与主管的连接和密封以及现场接头的发泡工作，但是不包括接头部分钢管的焊接工作。
4. Insulation layer and anticorrosive layer should avoid direct flame contact. For site installation, please follow the following procedures: trench excavation - basement treatment (drainage, sand cushion) - lower pipe - pipe welding - Inspection (water pressure) - Installation (pressure test) - foaming - sealing foaming holes. Joint Installation? The company can dispatch personnel to the engineering site for joint insulation, including joint casing installation, connection and sealing between joint casing and supervisor, and foaming work of field joint, but excluding welding work of joint steel pipe.
镀锌铁皮聚氨酯保温钢管是我们生活中经常使用到的，它也被全称为高密度聚乙烯塑料外护聚氨酯泡沫预制直埋保温管，它的主要作用就是用于用于液体、气体的输送管网， 化工管道保温工程石油、化工、集中供热热网、空调通风管道、市政工程等。
Galvanized iron polyurethane insulated steel pipe is often used in our life. It is also known as high-density polyethylene plastic external protective polyurethane foam precast directly buried insulation pipe, its main role is used for liquid and gas transportation pipeline network, chemical pipe insulation engineering, stone oil, chemical industry, central heating network, air conditioning. Ventilation pipeline, municipal engineering, etc.
