聚氨酯保温管的施工办法
Construction Method of Polyurethane Insulation Pipe
1、钢管的外向折叠,某些厂家过于与追求高效率,在消费进程中使压下量偏大,会形成钢管在轧制时发生折叠,在外表构成各种折线,使钢材强度大幅度下降。
1. External folding of steel pipes, some manufacturers are excessively pursuing high efficiency. In the process of consumption, the reduction is too large, which will lead to folding of steel pipes during rolling. It will form various folding lines on the surface, which will greatly reduce the strength of steel products.
2、管面呈现麻面,当用于制造钢管的轧槽经长工夫运用后会发生严重磨损,会使制造出的钢管外表凹凸不平。
2. The surface of the pipe is linen. When the groove used to manufacture the steel pipe is used for a long time, serious wear will occur, which will make the surface of the steel pipe uneven.
3、外表结疤,假如用来制造钢管的钢材中含杂质较多,材质不平均,并且用于加工的机器过于粗陋,就极能够使杂质咬入轧棍,惹起结疤。
3. Scar on the outside. If the steel used to make steel pipes contains more impurities, the material is uneven, and the machine used for processing is too crude, it can make impurities bite into the rolling rod and cause scarring.
4、钢管商标、印字不标准,优质管质量好、材质平均,停止印字时不会呈现不标准的景象,而材质不平均的钢管很容易在印字时呈现倾斜等景象。
4. The steel pipe trademark and printing are not standard, the quality of the high-quality pipe is good, and the material quality is average. When the printing stops, the steel pipe with uneven material will not show the scene of non-standard, and the steel pipe with uneven material will easily show the scene of inclination when printing.
5、内径尺寸动摇,当制钢资料不平均,制钢温度不波动或由于设备粗陋致使轧机弹跳大时,会使钢管内径呈现较大的动摇,致使钢筋受力不均,容易断裂。
5. The inner diameter of steel tube is shaken. When the steel-making data are not uniform, the steel-making temperature does not fluctuate or the rolling mill bounces due to rough equipment, the inner diameter of steel tube will be shaken greatly, resulting in uneven stress on steel bar and easy to fracture.
聚氨保温管道中首当其冲的就是钢套钢保温钢管,它采用没有混凝土构造的状况下也可以停止地下直埋的方式,即任务钢管的热收缩在外管内停止,从而降低了资料本钱,延长了施工日期,并保证了供热管道的平安性,可以在不同温度环境下更平安的普遍使用,尤其适用于低温蒸汽管道项目。运用温度可达150℃-450℃ 钢套钢保温管是由外护钢管加钢管防腐、聚氨酯泡沫保温层及内任务钢管组合而成。钢套钢蒸气复合保温管适用于保送2.5MPa、350摄氏度以下的蒸汽或其它介质,该产品用钢管做外防护层,具有强度高,不易损坏,施工检修简便,运用寿命长的优点。
In polyammonia heat preservation pipeline, the steel-jacketed steel heat preservation pipe is the most important one. It can also stop burying directly underground without concrete structure, that is, the thermal shrinkage of the task steel pipe stops inside the pipe, which reduces the cost of data, prolongs the construction date, and ensures the safety of the heating pipeline. It is more safe and widely used in the same temperature environment, especially for low temperature steam pipeline projects. The steel sleeve steel insulation pipe with temperature up to 150 -450 C is made up of external protection steel pipe and steel pipe anti-corrosion, polyurethane foam insulation layer and internal task steel pipe. Steel sleeve steel vapor composite insulating pipe is suitable for transporting steam or other media below 2.5 MPa and 350 degrees Celsius. The product uses steel pipe as outer protective layer, which has the advantages of high strength, not easy to damage, simple construction and maintenance, and long service life.

钢套钢保温管保温构造根据滑动方式不同分爲:内滑动式与外滑动式 1、内滑动式:保温构造由任务钢管、硅酸铝、减阻层、微孔硅酸钙、隔热层、不锈钢紧固钢带、铝箔反射层、聚氨酯保温层、外套钢管、外防腐层组成。 2、外滑动式:保温构造由任务钢管、玻璃棉保温隔热层、铝箔反射层、不锈钢紧固带、滑动导向支架、空气保温层、外护钢管、外防腐层组成。
According to different sliding modes, the thermal insulation structure of steel-jacketed insulation pipe can be divided into internal sliding mode and external sliding mode. 1. Internal sliding mode: thermal insulation structure consists of task steel pipe, aluminium silicate, drag reduction layer, micro-porous calcium silicate, thermal insulation layer, stainless steel fastening strip, aluminium foil reflective layer, polyurethane insulation layer, coated steel pipe and external anti-corrosion layer. 2. External sliding type: thermal insulation structure consists of task steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air thermal insulation layer, external steel pipe and external anti-corrosion layer.
聚氨酯直埋保温管由于具有恒久的耐腐蚀抗老化的特征,在使用中备受人们的欢送,故而有着很大的需求市场存在,也因而关于聚氨酯保温管的消费有着很大的消费数额要求。关于聚氨酯保温管的消费加工,需求针对详细用处与构造停止处置。关于有内管和外套管的保温层施行,聚氨酯发泡保温管通常是在两管之间间接灌注发泡浆料,一次成型发泡。
Polyurethane direct-buried insulating pipes are welcomed by people because of their long-lasting corrosion resistance and aging resistance. Therefore, there is a great demand market, and there is a great demand for consumption of polyurethane insulating pipes. With regard to the consumption and processing of polyurethane insulating pipes, it is necessary to stop disposing of them according to their detailed uses and structures. As for the application of insulation layer with inner tube and outer sleeve, polyurethane foamed insulation pipe is usually indirectly filled with foaming slurry between the two pipes, forming and foaming at one time.
