在保溫過(guò)程的處置處置之后，工作鋼管內(nèi)的溫度在不同工作環(huán)境和外部介質(zhì)的作用下得到保證。外表溫度滿足或滿足運(yùn)用請(qǐng)求的鋼管。
After the disposal and disposal of the insulation process, the temperature in the working steel pipe is guaranteed under the action of different working environment and external medium. Steel pipes whose external temperature meets or meets the application requirements.
保溫鋼管有哪些優(yōu)點(diǎn)?直埋保溫管的陰極維護(hù)是金屬防腐過(guò)程中的一種電化學(xué)維護(hù)辦法。與直埋保溫管的其他防腐工藝不同，他向受維護(hù)的金屬體施加電流，從而使受維護(hù)金屬體的電極電位發(fā)作負(fù)移，這是金屬失去自發(fā)性的趨向。從原子態(tài)轉(zhuǎn)變?yōu)殡x子態(tài)的態(tài)度。從基本上抑止腐朽蠟燭的發(fā)作。但是，這個(gè)過(guò)程必需在電解液中停止，因而埋入的鋼管十分合適陰極維護(hù)。
What are the advantages of insulating steel pipes? Cathodic maintenance of directly buried insulating pipes is an electrochemical maintenance method in the process of metal corrosion protection. Unlike other anticorrosive processes of directly buried insulating tubes, he applied current to the maintained metal body, thus causing the electrode potential of the maintained metal body to shift negatively, which is the tendency of metal losing spontaneity. The attitude of changing from atomic state to ionic state. Basically suppress the occurrence of decaying candles. However, this process must be stopped in the electrolyte, so the embedded steel tube is suitable for cathode maintenance.
另外，保溫鋼管的缺陷是什么?直埋保溫管自身的陰極維護(hù)和防腐層互相補(bǔ)充。防腐層的存在能夠大大減少陰極維護(hù)所耗費(fèi)的電流，并且陰極維護(hù)能夠補(bǔ)償防腐層缺乏完好性，從而完成平安性和經(jīng)濟(jì)性的圓滿分離。
In addition, what are the defects of the insulation pipe? The cathode maintenance and the corrosion protection layer of the directly buried insulation pipe complement each other. The existence of anticorrosive coating can greatly reduce the current consumed by cathodic maintenance, and the cathodic maintenance can compensate for the lack of integrity of the anticorrosive coating, thus completing the successful separation of safety and economy.
保溫鋼管選用技術(shù)1：高溫預(yù)制直埋保溫管是一種直埋式預(yù)制保溫管，具有良好的保溫性能，平安牢靠，工程造價(jià)低。它有效地處理了城市集中供熱130°C-600°C高溫傳熱預(yù)制直埋保溫管暴露管端保溫，滑動(dòng)光滑和防水問(wèn)題。
Selection technology of heat preservation pipe 1: High temperature prefabricated directly buried heat preservation pipe is a kind of directly buried prefabricated heat preservation pipe, which has good heat preservation performance, safety and reliability, and low cost. It effectively deals with the problems of heat preservation, smooth sliding and waterproof of the exposed end of the prefabricated direct-buried heat preservation pipe for 130 C-600 C high temperature heat transfer in urban central heating.
高溫預(yù)制直埋保溫管不只具有的技術(shù)和適用性能，難以與傳統(tǒng)的溝槽和架空鋪設(shè)管道相比，而且具有顯著的社會(huì)和經(jīng)濟(jì)效益，也是一種強(qiáng)有力的加熱措施。和。
High temperature prefabricated directly buried insulation pipe not only has advanced technology and applicability, it is difficult to compare with traditional trench and overhead pipeline laying, but also has remarkable social and economic benefits. It is also a powerful heating measure. And energy saving.
保溫鋼管選擇技術(shù)2：由于聚氨酯硬質(zhì)泡沫保溫層與鋼管表皮嚴(yán)密粘合，隔絕了空氣和水的浸透，起到了良好的防腐效果。同時(shí)，其發(fā)泡孔封鎖，吸水率小。高密度聚乙烯外殼和FRP外殼具有良好的耐腐蝕性，保溫性和機(jī)械性能。因而，工作鋼管的外皮簡(jiǎn)直不被外部空氣和水腐蝕。
The selection technology of heat preservation steel pipe 2: because the rigid polyurethane foam insulation layer is tightly adhered to the steel tube epidermis, the air and water are separated from the surface, and good anticorrosive effect is achieved. At the same time, the foaming hole is blocked and the water absorption rate is small. High density polyethylene shell and FRP shell have good corrosion resistance, thermal insulation and mechanical properties. Therefore, the outer skin of the working steel pipe is hardly corroded by external air and water.
保溫鋼管選用技巧3：鋼套管上的排水管能夠及時(shí)排出濕氣，也可作為日常運(yùn)轉(zhuǎn)的報(bào)警信號(hào)管。管道的熱補(bǔ)償采用波紋管補(bǔ)償器，裝置在套管內(nèi)構(gòu)成直埋方式。沒(méi)有必要樹(shù)立察看井，施工操作便當(dāng)，施工周期短。適用于保送低于2.5MPa和350攝氏度的蒸汽或其他介質(zhì)。本產(chǎn)品采用鋼管作為外維護(hù)層，具有強(qiáng)度高，不易損壞，施工維護(hù)簡(jiǎn)單，運(yùn)用壽命長(zhǎng)的優(yōu)點(diǎn)。
Selection Skills of Insulating Steel Pipe 3: Drainage pipe on steel casing can discharge moisture in time, and can also be used as alarm signal pipe for daily operation. High quality bellows compensator is used for heat compensation of pipeline. The device is directly buried in the casing. There is no need to set up inspection wells. The construction operation is convenient and the construction period is short. Suitable for delivering steam or other media below 2.5 MPa and 350 degrees Celsius.
