Description

耐冲击的金属复合管
技术领域
本发明涉及一种耐冲击的金属复合管。
背景技术
双相不锈钢具有良好的焊接性能,与铁素体不锈钢及奥氏体不锈钢相比,它既不像铁素体不锈钢的焊接热影响区,由于晶粒严重粗化而使塑韧性大幅降低,也不像奥氏体不锈钢那样,对焊接热裂纹比较敏感。
双相不锈钢由于其特殊的优点,广泛应用于石油化工设备、海水与废水处理设备、输油输气管线、造纸机械等工业领域,近些年来也被研究用于桥梁承重结构领域,具有很好的发展前景。
节约型双相钢"经常会出现的焊接性能问题。而焊接标准双相钢并不是一个问题,而且不论采用何种工艺,都有适合这些应用的焊材。从金相的角度来看,焊接2101(1.4162)根本就没有问题,实际上它甚至要比标准级的双相钢更加容易焊接,因为这种材料事实上可以采用乙炔焊工艺来进行焊接,而对于标准双相钢材料而言,始终必须避免使用这种工艺。焊接2101所面临的实际问题是熔池的粘度不同,因此可湿性差了一点。这迫使操作人员在焊接的过程中更加多地使用电弧焊,而这正是问题的所在。尽管可以通过选择超合金化焊材加以弥补,但是我们经常希望选择匹配的焊材。
在2101中,也存在低温热影响区和高温热影响区中的显微结构之间的热影响区相互作用,比2304、2205或2507更加有利。在以2101进行试验时,也已经发现由于镍含量较低,因此产生了含有较多氮与锰的不同类型的"回火色",而这影响了腐蚀性能。在电弧和熔池中发生的这一成分损失是由于氮与锰的蒸发与熔敷,这对于双相钢等级的材料来说是一个新问题,因此在这次讲课中将作了较多描述。
发明内容
   本发明提供一种具有承压性能好、耐腐蚀性和耐冲击优点的耐冲击的金属复合管。
本发明的技术方案是:一种耐冲击的金属复合管,所述的耐冲击的金属复合管包括镀层的双相不锈钢、基层的热塑性材料和复层的锡合金组合而成,所述双相不锈钢包括铁素体不锈钢和奥氏体不锈钢,所述热塑性材料为高密度聚乙烯,所述锡合金包括铅、锑、铜和锡,所述的双相不锈钢占耐冲击的金属复合管总体分量的51%-59%,所述的热塑性材料占耐冲击的金属复合管总体分量的2%-4%,所述的锡合金占耐冲击的金属复合管总体分量的38%-46%。
在本发明一个较佳实施例中,所述的高密度聚乙烯基包括乙烯、浓硝酸、芳香烃和卤化烃。
在本发明一个较佳实施例中,所述的双相不锈钢占耐冲击的金属复合管总体分量的58%,所述的热塑性材料占耐冲击的金属复合管总体分量的2%,所述的锡合金占耐冲击的金属复合管总体分量的40%。
本发明的一种耐冲击的金属复合管,具有承压性能好、耐腐蚀性和耐冲击的优点。
具体实施方式
下面对本发明的较佳实施例进行详细阐述,以使本发明的优点和特征能更易于被本领域技术人员理解,从而对本发明的保护范围做出更为清楚明确的界定。
其中,所述的耐冲击的金属复合管包括镀层的双相不锈钢、基层的热塑性材料和复层的锡合金组合而成,所述双相不锈钢包括铁素体不锈钢和奥氏体不锈钢,所述热塑性材料为高密度聚乙烯,所述锡合金包括铅、锑、铜和锡,所述的双相不锈钢占耐冲击的金属复合管总体分量的51%-59%,所述的热塑性材料占耐冲击的金属复合管总体分量的2%-4%,所述的锡合金占耐冲击的金属复合管总体分量的38%-46%,所述的高密度聚乙烯基包括乙烯、浓硝酸、芳香烃和卤化烃。
进一步说明,所述的双相不锈钢占耐冲击的金属复合管总体分量的58%,所述的热塑性材料占耐冲击的金属复合管总体分量的2%,所述的锡合金占耐冲击的金属复合管总体分量的40%。
在进一步说明,双相不锈钢由于具有奥氏体+铁素体双相组织,且两个相组织的含量基本相当,故兼有奥氏体不锈钢和铁素体不锈钢的特点。屈服强度可达400Mpa-550MPa,是普通奥氏体不锈钢的2倍。与铁素体不锈钢相比,双相不锈钢的韧性高,脆性转变温度低,耐晶间腐蚀性能和焊接性能均显著提高;同时又保留了铁素体不锈钢的一些特点,如475℃脆性、热导率高、线膨胀系数小,具有超塑性及磁性等。与奥氏体不锈钢相比,双相不锈钢的强度高,特别是屈服强度显著提高,且耐孔蚀性、耐应力腐蚀、耐腐蚀疲劳等性能也有明显的改善。
在进一步说明,高密度聚乙烯是一种不透明白色腊状材料,比重比水轻,比重为0.941-0.960,柔软而且有韧性,但比LDPE略硬,也略能伸长,无毒,无味。易燃,离火后能继续燃烧,火焰上端呈黄色,下端呈蓝色,燃烧时会熔融,有液体滴落,无黑烟冒出,同时,发出石蜡燃烧时发出的气味。耐酸碱,耐有机溶剂,电绝缘性优良,低温时,仍能保持一定的韧性。表面硬度,拉伸强度,刚性等机械强度都高于LDPE,接近于PP,比PP韧,但表面光洁度不如PP。本发明提供一种耐冲击的金属复合管,具有承压性能好、耐腐蚀性和耐冲击的优点。
本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可不经过创造性劳动想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
