Description

双层金属耐蚀管接头
本实用新型涉及防耐蚀双层金属材料的管接头。
管接头是石油、化工、湿法冶金等工业生产设备大量管道系统中广泛应用的重要元件，许多管件只要求内腔能承受腐蚀性液、汽流的腐蚀。目前该类产品均是由某一种昂贵的耐蚀金属材料制造的。这些材料有不锈钢、钛、钛合金、镍、镍合金、铝、铝合金。这些由一种材料作成的管接头比碳素钢、碳素低合金钢制造的管接头要昂贵的多。
本实用新型的目的在于提供一种内层是上述任何一种耐蚀金属材料、外层是碳素钢或碳素低合金钢制成的双层内腔防腐蚀管接头。这种管接头具有节约贵重金属材料、造价低，且能提高管接头强度等优点。
本实用新型的技术方案是这样实现的：这种双层金属管接头外层是碳素钢或碳素低合金钢，内层分别是不锈钢、钛、钛合金、镍、镍合金、铝、铝合金。管接头的壁厚T＝0.02-0.25倍的管接头外径D、D1，内层壁厚T1＝0.2-0.6T。
附图实施例：
图1是双层金属耐蚀三通管接头；
图2是双层金属弯头；
图3是双层金属大小头。
实例1：
双层金属三通管接头，D＝57，D1＝45，C＝64，M＝44，T＝5.6，T1＝3；
实例2：
双层金属三通管接头，D＝D1＝57，C＝64，M＝60，T＝5.6，T1＝3；
实例3：
双层金属弯头，D＝57，α＝90，L＝10，R＝76，T＝5.6，T1＝2；
实例4：
双层金属大小接头，D＝57，D1＝45，L＝76，T＝5.6，T1＝2。
