在保温过程的处置处置之后，工作钢管内的温度在不同工作环境和外部介质的作用下得到保证。外表温度满足或满足运用请求的钢管。
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.
保温钢管有哪些优点?直埋保温管的阴极维护是金属防腐过程中的一种电化学维护办法。与直埋保温管的其他防腐工艺不同，他向受维护的金属体施加电流，从而使受维护金属体的电极电位发作负移，这是金属失去自发性的趋向。从原子态转变为离子态的态度。从基本上抑止腐朽蜡烛的发作。但是，这个过程必需在电解液中停止，因而埋入的钢管十分合适阴极维护。
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，保温钢管的缺陷是什么?直埋保温管自身的阴极维护和防腐层互相补充。防腐层的存在能够大大减少阴极维护所耗费的电流，并且阴极维护能够补偿防腐层缺乏完好性，从而完成平安性和经济性的圆满分离。
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.
保温钢管选用技术1：高温预制直埋保温管是一种直埋式预制保温管，具有良好的保温性能，平安牢靠，工程造价低。它有效地处理了城市集中供热130°C-600°C高温传热预制直埋保温管暴露管端保温，滑动光滑和防水问题。
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.
高温预制直埋保温管不只具有的技术和适用性能，难以与传统的沟槽和架空铺设管道相比，而且具有显着的社会和经济效益，也是一种强有力的加热措施。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.
保温钢管选择技术2：由于聚氨酯硬质泡沫保温层与钢管表皮严密粘合，隔绝了空气和水的浸透，起到了良好的防腐效果。同时，其发泡孔封锁，吸水率小。高密度聚乙烯外壳和FRP外壳具有良好的耐腐蚀性，保温性和机械性能。因而，工作钢管的外皮简直不被外部空气和水腐蚀。
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.
保温钢管选用技巧3：钢套管上的排水管能够及时排出湿气，也可作为日常运转的报警信号管。管道的热补偿采用波纹管补偿器，装置在套管内构成直埋方式。没有必要树立察看井，施工操作便当，施工周期短。适用于保送低于2.5MPa和350摄氏度的蒸汽或其他介质。本产品采用钢管作为外维护层，具有强度高，不易损坏，施工维护简单，运用寿命长的优点。
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. This product uses steel pipe as outer maintenance layer, which has the advantages of high strength, not easy to damage, simple construction and maintenance, and long service life.
