QT450球墨铸铁介绍：

为铁素体型球墨铸铁，韧性和塑性较高。低温时，韧性向脆性转变，但低温冲击值较高，且有一定的抗温度急性变和耐蚀性。用途较广，在农机中用于铧犁、犁柱、差速器壳等；通用机械中用作阀体、高低压气缸等；还可用于输电线路的钢帽等。

球墨铸铁是碳以球形石墨的形态存在，其机械性能远胜于灰口铁而接近于钢，它具有优良的铸造、切削加工和耐磨性能，有一定的弹性，广泛用于制造曲轴、齿轮、活塞等高级铸件以及多种机械零件。

QT450 ductile iron introduction:

For ductile iron with ferrite type, toughness and plasticity are high. At low temperature, toughness changes to brittleness, but low temperature impact value is higher, and has certain resistance to temperature acute change and corrosion resistance. It is widely used in agricultural machinery, such as plough, plough column, differential case, etc. It is also used as valve body, high and low pressure cylinder in general machinery, steel cap of transmission line, etc.

Ductile iron is a kind of carbon which exists in the form of spherical graphite. Its mechanical properties are much better than gray iron and close to steel. It has excellent casting, cutting and wear resistance. It has certain elasticity and is widely used in manufacturing high-grade castings such as crankshafts, gears, pistons and many kinds of mechanical parts.

双球橡胶接头优点：
1、产品本身设计比单球型长，具有良好的减震和降噪效果。
2、具有良好的伸缩位移性能。
3、使用寿命比单球使用寿命长。
4、在国外使用双球橡胶接头的概率大于单球型橡胶接头。

5、体积小、重量轻、弹性好、安装维修方便。

6、安装后可吸收管道震动产生的横向、轴向、角向位移；不受管道不同心，法兰不平行的限制。

7、安装后可降低管道水泵等震动产生的噪音，吸振能力强。

8、内无缝高压橡胶接头，选择不同的橡胶材质在耐高温、耐酸碱、耐油的管道中更有效地防止了腐蚀性介质对橡胶接头内壁的侵蚀，提高了使用寿命。

9、具有良好的综合性能，所以它广泛用于化工、建筑、给水、排水、石油、轻重工业、冷冻、卫生、水暖、消防、电力等基础工程。
10、根据材料不同可制成耐酸、耐碱、耐腐蚀、耐油、耐高温、耐辐射、耐磨、耐老化等各个品种，适应多种介质和环境。

The advantages of double ball rubber joints are:

1, the design of the product itself is longer than that of the single ball type, and has good damping and noise reduction effects.

2. It has good performance of telescopic displacement.

3, the service life is longer than that of the single ball.

4, the probability of using double ball rubber joints abroad is greater than that of single ball rubber joints.

5, small volume, light weight, good elasticity, easy installation and maintenance.

6. After installation, the transverse, axial and angular displacement caused by vibration of pipeline can be absorbed; it is not restricted by the dissymmetry of pipeline and the non-parallel flange.

7, after installation, it can reduce the vibration and noise generated by pipes and pumps.

8. Internal seamless high-pressure rubber joints, choose different rubber materials in high-temperature, acid-alkali resistance, oil-resistant pipelines to effectively prevent the corrosive medium on the rubber joints of the corrosion of the inner wall, improve service life.

9. It has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire protection, electricity and other basic projects.

10. According to the different materials can be made into acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, high temperature-resistant, radiation-resistant, wear-resistant, aging-resistant and other varieties, adapt to a variety of media and environment.
