黑夹克直埋式直缝钢管构造特点
Structural Characteristics of Black Jacket Directly Buried Straight Seam Steel Pipe
一局部:防腐内任务钢管
Part I: Anti-corrosion Internal Task Steel Pipe
普通状况下依据客户的设计要求或国度规范的设计要求来停止选择执行规范爲GB3092-93的直缝焊管、GB8163-87的无缝钢管以及执行规范爲GB9711-88、SY/T5037的螺旋钢管等来作爲其保送介质的内任务钢管,钢管外表停止抛丸除锈技术等级到达GB8923规范中的SA2级,其钢管外表的粗糙度到达GB6060.5规范中的R=12.5微米,其钢管外表停止除污除锈技术后,会涂刷上一层防腐涂料,来进一步增强其防水防腐蚀的功能,内任务钢管的管径大小分爲多种型号,来供客户选择。(内任务钢管的局部管径型号:Φ20、25、32、34、38、40、42、48、57、76、89、108、133、159、219、273、325、377、426、478、529、630、720、820、920、1020、1120、1220、1320、1420等多种型号。)
Under normal conditions, according to the design requirements of customers or the design requirements of national codes, the straight seam welded pipe GB3092-93, seamless steel pipe GB8163-87 and spiral steel pipe GB9711-88 and SY/T5037 are selected as the internal task steel pipe for its delivery medium. The technical grade of shot blasting and rust removal on the outer surface of steel pipe reaches SA2 level in GB8923 specification, and the outer appearance of steel pipe reaches SA2 level in GB8923 specification. The roughness of the steel pipe reaches R=12.5 micron in GB6060.5 specification. After the surface of the steel pipe stops decontamination and rust removal technology, it will be coated with an anticorrosive coating to further enhance its waterproof and anticorrosive function. The diameter of the inner task steel pipe can be divided into several types for customers to choose. (Local diameter models of internal task steel pipes: 20, 25, 32, 34, 38, 40, 42, 48, 57, 76, 89, 108, 133, 159, 219, 273, 325, 377, 426, 478, 529, 630, 720, 820, 920, 1020, 1120, 1220, 1320, 1420, etc.)
第二局部:硬质聚氨酯泡沫塑料保温层
Second part: rigid polyurethane foam insulation layer
硬质聚氨酯泡沫塑料保温层是由高功用聚醚多元醇和甲基多苯基多异氰酸酯爲原料,依照一定的比例停止谐和,经过特殊的设备借助于液体的活动性,将谐和后的液体一次性注入内任务钢管与高密度聚乙烯外护管之间的空隙中,经过化学反响发生发泡,使其发泡充沛的布满内任务钢管与高密度聚乙烯外护管之间的空腔中,借助于硬质聚氨酯泡沫塑料超强的粘结性,使二者紧紧的粘结成爲一个不易零落的全体。
Rigid polyurethane foam insulation layer is made of high-performance polyether polyols and methyl polyphenyl polyisocyanate as raw materials, according to a certain proportion to stop harmony, through special equipment with the help of liquid activity, the harmony of the liquid once injected into the gap between the internal task steel pipe and the high-density polyethylene outer guard pipe, through chemical reaction, foaming, making it foam filling. With the help of the super-strong cohesion of rigid polyurethane foam plastics in the cavity between the high-density polyethylene outer guard pipe and the full-filled inner task steel pipe, the tight cohesion of the two becomes a whole which is not easy to be scattered.

第三局部:高密度聚乙烯外护管
Part 3: High Density Polyethylene External Protector
高密度聚乙烯外护管在制造进程中选用的是优良的PE高密度聚乙烯爲原料,采用先进的真空定径设备和高明的消费工艺来停止消费,高密度聚乙烯外护管的管径大小和管材的壁厚,均可以依据客户的设计要求或国度规范的设计要求来停止消费,高密度聚乙烯外护管的管材颜色普通状况下分爲黑色和黄色两种颜色,及黑夹克管和黄夹克管,其管材的根底资料和功能目标完全相反。
High density polyethylene exterior guard pipe is made of excellent PE high density polyethylene as raw material, advanced vacuum sizing equipment and smart consumption process are adopted to stop consumption. The diameter and wall thickness of high density polyethylene exterior guard pipe can stop consumption according to the design requirements of customers or the design requirements of national standards. High density polyethylene exterior guard pipe Under normal conditions, the pipes can be divided into black and yellow colors, and black jacket and yellow jacket pipes. The basic data and functional objectives of the pipes are completely opposite.
直埋式聚氨酯保温管的劣势特点:
The disadvantage characteristics of direct-buried polyurethane insulating pipe:
1、直埋式聚氨酯保温管选用的是硬质聚氨酯泡沫塑料作爲其保温层,硬质聚氨酯泡沫塑料的闭孔率到达百分之九十七左右,其吸水率极低,避免了外界水、腐蚀性液体、微生物等的浸入,阻止了微生物的开展与消费,使直埋式聚氨酯保温管的运用寿命失掉进一步的保证。
1. The rigid polyurethane foam is chosen as the insulation layer of the direct-buried polyurethane insulation pipe. The closed-cell ratio of the rigid polyurethane foam plastic reaches about 97%, and its water absorption rate is very low. It avoids the immersion of external water, corrosive liquid and microorganisms, prevents the development and consumption of microorganisms, and further loses the service life of the direct-buried polyurethane insulation pipe. Guarantee.
2、硬质聚氨酯泡沫塑料保温层的保温功能极高,其热损失仅爲传统管材的百分之二十五,临时少量的运转运用,可以节省少量的动力,从而降低了动力的本钱。
2. The thermal insulation function of rigid polyurethane foam plastic insulation layer is very high, its heat loss is only 25% of the traditional pipes. Temporary small amount of operation can save a small amount of power, thus reducing the cost of power.
3、由于直埋式聚氨酯保温管具有防水防腐蚀的功能,所以在施工进程中不需求敷设管沟,可以间接埋上天下或水中,延长了施工周期,降低了施工本钱。
3. Because the direct-buried polyurethane insulation pipe has the function of waterproof and anticorrosion, it is not necessary to lay pipe trenches in the construction process. It can be indirectly buried in the world or water, prolonging the construction period and reducing the construction cost.
4、依据国外相关材料调查显示,以正确的办法运用直埋式聚氨酯保温管,可以使其运用寿命到达30年至50年左右。
4. According to the investigation of foreign related materials, the application of direct-buried polyurethane insulation pipe in the right way can make its service life reach about 30 to 50 years.
5、易于施工、施工周期短、操作复杂快捷、一次成型等劣势特点。
5. Easy to construct, short construction period, complex and fast operation, one-time forming and other disadvantages.
