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、聚氨酯灌注時，施工環(huán)境溫度宜為10-40℃，相對濕度應小于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溫層應充分熟化后，再進行下道工序的施工。

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溫層表面應當光滑，無明顯凹陷突出。勤奮不是天生就有的，而是后天自己養(yǎng)成的。產(chǎn)生勤奮的原因有多種，有的是心懷抱負和信念，也有的是因為某種原因或在某事上受挫，從而勤勉起來。但是，只要勤于工作，就會有成功的必然。保溫管保溫管是絕熱管道的簡稱，保溫管用于液體、氣體及其他介質(zhì)的輸送，在石油、化工、航天、軍shi、集中供熱熱、空調(diào)、市政等等管道的絕熱保溫工程。

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.

施工應注意的事項：

Notices to be paid attention to in construction:

1、施工時應避免地下水及雨水的浸泡，若端頭不慎浸水，連接外套前應做干燥處理。

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、管材應儲存在平整的場地，整齊碼放，碼放高度應小于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、管材吊裝在輕裝輕放，禁碰撞、拋擲，禁用鋼絲繩直吊管身。

3. Pipe hoisting is light and light, collision and throwing are forbidden, and pipe body is forbidden to be hoisted by wire rope.

4、保溫層及防腐層應避免火焰直接接觸。現(xiàn)場安裝請按下列程序：管溝開挖--基底處理（排水、墊砂）－下管--鋼管焊接－檢驗（水壓）－安裝（試壓）－發(fā)泡－封發(fā)泡孔。接頭安裝?公司可以派遣人員到工程現(xiàn)場進行接頭的保溫工作，包括接頭外套管的安裝、接頭外套管與主管的連接和密封以及現(xiàn)場接頭的發(fā)泡工作，但是不包括接頭部分鋼管的焊接工作。

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.

鍍鋅鐵皮聚氨酯保溫鋼管是我們生活中經(jīng)常使用到的，它也被全稱為高密度聚乙烯塑料外護聚氨酯泡沫預制直埋保溫管，它的主要作用就是用于用于液體、氣體的輸送管網(wǎng)， 化工管道保溫工程石油、化工、集中供熱熱網(wǎng)、空調(diào)通風管道、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.
