它是绝缘法兰的替代产品。
绝缘接头是管道系统中阴极保护的重要装置，它是绝缘法兰的替代品。
Insulating joint is the important equipment of cathodic protection which is used in the system of pipeline, and instead of insulating flange.
与绝缘法兰不同的是，绝缘接头的左法兰和勾圈是通过焊接实现连接的。
Insulating joint which is different from insulating flange achieve connection through welding(appendix A).
绝缘法兰漏电会缩小阴极保护站的有效保护范围，增大阴极保护站的输出电流。
The electric leakage of insulated flange will narrow the effective protection scope and widen the output current for CP station.
就绝缘法兰是否漏电，提出了电流方向法、管道电流法及接地电阻法等判断方法。
Three methods to judge the electric leakage of flange are put forward, that is, current direction method, pipeline current method and earth resistance method.
在新、旧管子连接处安装绝缘法兰，破坏了长管道的原电池，即：阳极(新管子)和阴极(旧管子)间电断路。
By insulating flange at the junction between the new and old pipe, the long line galvanic cell is "broken up" - the anode (new pipe) is electrically separated from the cathode (old pipe).
结果表明，采用电绝缘法兰、套管、以及在整个管系中采用电绝缘吊架、支架，是舰船海水管系中防止异种金属接触腐蚀目前最有效的绝缘措施。
