聚氨酯保溫管的施工辦法
Construction Method of Polyurethane Insulation Pipe
1、鋼管的外向折疊,某些廠家過于與追求高效率,在消費進程中使壓下量偏大,會形成鋼管在軋制時發(fā)生折疊,在外表構(gòu)成各種折線,使鋼材強度大幅度下降。
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、管面呈現(xiàn)麻面,當(dāng)用于制造鋼管的軋槽經(jīng)長工夫運用后會發(fā)生嚴(yán)重磨損,會使制造出的鋼管外表凹凸不平。
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、外表結(jié)疤,假如用來制造鋼管的鋼材中含雜質(zhì)較多,材質(zhì)不平均,并且用于加工的機器過于粗陋,就極能夠使雜質(zhì)咬入軋棍,惹起結(jié)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、鋼管商標(biāo)、印字不標(biāo)準(zhǔn),優(yōu)質(zhì)管質(zhì)量好、材質(zhì)平均,停止印字時不會呈現(xiàn)不標(biāo)準(zhǔn)的景象,而材質(zhì)不平均的鋼管很容易在印字時呈現(xiàn)傾斜等景象。
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、內(nèi)徑尺寸動搖,當(dāng)制鋼資料不平均,制鋼溫度不波動或由于設(shè)備粗陋致使軋機彈跳大時,會使鋼管內(nèi)徑呈現(xiàn)較大的動搖,致使鋼筋受力不均,容易斷裂。
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.
聚氨保溫管道中首當(dāng)其沖的就是鋼套鋼保溫鋼管,它采用沒有混凝土構(gòu)造的狀況下也可以停止地下直埋的方式,即任務(wù)鋼管的熱收縮在外管內(nèi)停止,從而降低了資料本錢,延長了施工日期,并保證了供熱管道的平安性,可以在不同溫度環(huán)境下更平安的普遍使用,尤其適用于低溫蒸汽管道項目。運用溫度可達150℃-450℃ 鋼套鋼保溫管是由外護鋼管加鋼管防腐、聚氨酯泡沫保溫層及內(nèi)任務(wù)鋼管組合而成。鋼套鋼蒸氣復(fù)合保溫管適用于保送2.5MPa、350攝氏度以下的蒸汽或其它介質(zhì),該產(chǎn)品用鋼管做外防護層,具有強度高,不易損壞,施工檢修簡便,運用壽命長的優(yōu)點。
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.

鋼套鋼保溫管保溫構(gòu)造根據(jù)滑動方式不同分爲(wèi):內(nèi)滑動式與外滑動式 1、內(nèi)滑動式:保溫構(gòu)造由任務(wù)鋼管、硅酸鋁、減阻層、微孔硅酸鈣、隔熱層、不銹鋼緊固鋼帶、鋁箔反射層、聚氨酯保溫層、外套鋼管、外防腐層組成。 2、外滑動式:保溫構(gòu)造由任務(wù)鋼管、玻璃棉保溫隔熱層、鋁箔反射層、不銹鋼緊固帶、滑動導(dǎo)向支架、空氣保溫層、外護鋼管、外防腐層組成。
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.
聚氨酯直埋保溫管由于具有恒久的耐腐蝕抗老化的特征,在使用中備受人們的歡送,故而有著很大的需求市場存在,也因而關(guān)于聚氨酯保溫管的消費有著很大的消費數(shù)額要求。關(guān)于聚氨酯保溫管的消費加工,需求針對詳細用處與構(gòu)造停止處置。關(guān)于有內(nèi)管和外套管的保溫層施行,聚氨酯發(fā)泡保溫管通常是在兩管之間間接灌注發(fā)泡漿料,一次成型發(fā)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.
