作者: -1    发布时间: 2018-08-03    次浏览
球墨铸铁管是指用铸铁浇铸成型的管子。球墨铸铁管用于给水、排水和煤气输送管线,它包括铸铁直管和管件。劳动强度小。按铸造方法不同,分为连续球墨铸铁管和离心球墨铸铁管,其中离心球墨铸铁管又分为砂型和金属型两种。按材质不同分为灰口球墨铸铁管和球墨球墨铸铁管。按接口形式不同分为柔性接口、法兰接口、自锚式接口、刚性接口等。其中,柔性球墨铸铁管用橡胶圈密封;法兰接口球墨铸铁管用法兰固定,内垫橡胶法兰垫片密封;刚性接口一般球墨铸铁管承口较大,直管插入后,用水泥密封,此工艺现已基本淘汰。
Ductile iron pipes refer to pipes made of cast iron. Ductile iron pipes are used for water supply, drainage and gas transportation pipelines, including cast iron straight pipes and fittings. The labor intensity is small. According to different casting methods, it can be divided into continuous ductile iron pipe and centrifugal ductile iron pipe, among which centrifugal ductile iron pipe can be divided into sand mold and metal mold. They are divided into gray ductile iron pipes and spheroidal graphite cast iron pipes according to their materials. According to the form of interface, it can be divided into flexible interface, flange interface, self anchored interface and rigid interface. The flexible ductile iron pipe is sealed with rubber ring, the flange interface spheroidal graphite cast iron pipe is fixed with flange, and the inner pad rubber flange gasket is sealed; the rigid interface is usually large, and the straight pipe is inserted and the cement is sealed with cement. The process has been basically eliminated.
 
按其制造方法可分为:砂型离心承插直管、连续铸铁直管及砂型铁管。

According to their manufacturing methods, they can be divided into: sand type centrifugal plug straight pipe, continuous cast iron straight pipe and sand type iron pipe.


球墨铸铁管的分类

 
按其所用的材质不同可分为:灰口铁管、球墨球墨铸铁管及高硅铁管。
According to the material used, it can be divided into: gray iron pipe, spheroidal graphite cast iron pipe and high silicon iron pipe.
 
1、给水球墨铸铁管:给水球墨铸铁管使用18号以上的铸造铁水经添加球化剂后,经过离心球墨铸铁机高速离心铸造成的管道,球墨球墨铸铁管具有铁的本质、钢的性能,防腐性能优异、延展性能好,密封效果好,安装简易、主要用于市政、工矿企业给水、输气,输油等。是供水管材的首选,具有很高的性价比。
1.Water ball ink cast iron pipe: after adding spheroidizing agent of more than 18 cast iron water to the water ball ink cast iron pipe, the ducts produced by centrifugal cast iron casting machine are made of centrifugal cast iron machine at high speed centrifugal casting. The ball ink cast iron pipe has the essence of iron and the properties of steel. For municipal, industrial and mining enterprises water supply, gas transmission, oil and so on. It is the first choice for water supply pipes, and has high cost performance.
2、砂型离心铸铁直管:砂型离心铸铁直管之材质为灰口铸铁,适用于水及煤气等压力流体的输送。
2. Sand mold centrifugal cast iron straight pipe: The material of sand mold centrifugal cast iron straight pipe is grey cast iron, which is suitable for conveying water and gas and other pressure fluids.
3、连续铸铁直管:连续铸铁直管即连续铸造的灰口球墨铸铁管,适用于水及煤气等压力流体的输送。
3. Continuous cast iron straight pipe: Continuous cast iron straight pipe is continuous casting gray nodular cast iron pipe, suitable for water and gas pressure fluid transmission.
4、排水球墨铸铁管:普通排水铸铁承插管及管件。柔性抗震接口排水铸铁直管,此类球墨铸铁管采用橡胶圈密封、螺栓紧固,在内水压下具有良好的挠曲性、伸缩性。能适应较大的轴向位移和横向由挠变形,适用于高层建筑室内排水管,对地震区尤为合适。从接口形式看可分为:W型柔性铸铁排水管,B型柔性铸铁排水管,A型柔性铸铁排水管。
 4. Drain ductile iron pipe: common drainage cast iron socket pipe and fittings. The flexible aseismic interface drains cast iron straight pipe. This kind of ductile cast iron pipe is sealed by rubber ring and bolt, and has good flexure and flexibility under internal water pressure. It can adapt to large axial displacement and transverse deflection, and is suitable for indoor drainage pipes of high-rise buildings, especially for earthquake areas. From the interface form, it can be divided into: W type flexible cast iron drain pipe, B type flexible cast iron drain pipe and A type flexible cast iron drain pipe.


连续灰口球墨铸铁管的公称口径为75~1200毫米。直管长度有4米、5米及6米;按壁厚不同分LA、A和B三级。砂型离心灰口球墨铸铁管的公称口径为200~1000毫米,有效长度有5米及6米;按壁厚不同分P、G两级。强度大、韧性好、管壁薄、金属用量少、能承受较高的压力。
The nominal diameter of the continuous gray ductile iron pipe is 75~1200 millimeters. Straight tube length is 4 meters, 5 meters and 6 meters; according to wall thickness, it is divided into three grades: LA, A and B. The nominal diameter of sand mold centrifugal grey nodular cast iron pipe is 200-1000 mm, and the effective length is 5 meters and 6 meters. High strength, good toughness, thin wall, less metal consumption, and high pressure.
球墨铸铁管的公称口径为80~2200毫米,与灰口球墨铸铁管相比,强度大、韧性好、管壁薄、金属用量少、能承受较高的压力,有效长度有5米,6米及8米;按壁厚不同分P、G两级。是球墨铸铁管材的发展方向。球墨球墨铸铁管采用炼铁高炉生产的低磷、低硫的优质铸造铁水,按当前国际上先进的离心铸造、退火工艺,水冷金属型离心铸管机浇铸而成,经过退火、承插口修整、水压试验、内壁衬层水泥、水泥衬层养生、水磨水泥内衬、外壁涂敷沥青漆、沥青漆烘烤、承口防锈处理、喷唛头及包装等多道工序的精心处理,具有高强度、高延伸率、耐腐蚀的钢筋铁骨。
The nominal diameter of the ball ink cast iron pipe is 80~2200 millimeters. Compared with the gray ductile cast iron pipe, it has large strength, good toughness, thin tube wall, less metal consumption and can bear higher pressure. The effective length is 5 meters, 6 meters and 8 meters, and P and G two are divided according to the thickness of the wall. It is the development direction of ductile iron pipe. The ball ink cast iron pipe is made of low phosphorus and low sulphur cast iron water produced by iron smelting blast furnace. It is cast by the current international advanced centrifugal casting, annealing process, water cooled metal centrifugal casting machine, after annealing, socket dressing, water pressure test, lining cement, cement lining and cement lining. It has a high strength, high elongation and corrosion resistant steel frame with high strength, high elongation and corrosion resistance.
管与管之间的连接,采用承插式或法兰盘式接口形式;按功能又可分为柔性接口和刚性接口两种。柔性接口用橡胶圈密封,允许有一定限度的转角和位移,因而具有良好的抗震性和密封性,比刚性接口安装简便快速,按铸造方法不同,劳动强度小。
The connection between pipe and pipe is in the form of plug-in or flange interface, which can be divided into flexible interface and rigid interface according to function. The flexible interface is sealed with rubber ring, allowing a certain limit of angle and displacement, so it has good aseismic and sealing properties. It is easier to install than rigid interface, and the labor intensity is small according to the different casting methods.
