MMO/Ti柔性阳极是新一代的长寿命柔性阳极,其主要特点是综合了MMO/Ti阳极的发生电流大和铜芯电缆的导电性能佳的优点。由于发生电流大,接地电阻小,特别适用于高阻地区或涂层破损的管道阴极保护,也可用于大型储罐罐底板外加电流阴极保护及输油气站场、石化厂、电厂埋地金属设施的区域性阴极保护。由于阳极本身含有焦碳粉,因此现场安装时不需要加填料,安装方便快捷。
特点:
●连续的MMO/Ti线性阳极
●连续的内部接头电缆
●焦炭填充在织物包覆层内
●透气织物包覆
优点:
●输出电流分布均匀,即使管道防腐层破损严重,也能保证电
流的均匀分布,实现阴极保护;
●保护电位分布均匀,避免过保护和保护不足;
●针对性强,对其它金属构筑物干扰影响小;
●杂散电流干扰小,在复杂管网区域内可解决屏蔽和干扰问题
●可与管道同沟敷设,解决了岩石、高电阻率区段无法敷设阳
极的问题;
●安装容易,成套产品,可直接安装,不需要额外的组件和材料
●施工简便,与管道同时施工,同沟敷设,便于安装;同时可大幅减少电流漏失,提高保护电流利用效率。
安装方式:
●电缆牵引式铺设
●挖沟铺设
●铺设于罐底或罐间的砂层上

MMO/Ti Flexible anode is flexible anode with long service life and it is mainly characterized by the combination of large generation current advantages of MMO/Ti anode and superior conductivity performance of copper core cable. Thanks to its large generation current and small grounding resistance, it is particularly suitable for cathodic protection of the pipes installed in regions with high resistance or the pipes suffering from damages to coats, and it may also be used in impressed current cathodic protection for base plates of large storage tanks as well as regional cathodic protection for buried metal facilities in oil/gas transfer fields, petrochemical plants and power plants. As the anode itself contains coke powder, it is not needed to add packing materials during field installation, which enables convenient and fast installation.
Features:
Continuous MMO/Ti linear anode
Continuous inner connector cable
Coke is filled in fabric cladding
Breathable fabric cladding
Advantages:
Uniform distribution of output current guarantees uniform distribution of current used for cathodic protection, regardless of the seriousness of damages to pipecoating;
Uniform distribution of protective potential prevents over-protection and insufficient protection;
Targeted design minimizes the interference and affects to other metallic structures;
Small stray current helps solve the problems of shielding and interference in the regions with complex pipeline networks;
The anodes can be laid in the same ditch with pipelines, which helps solve the problem of laying anode in rocky and high-resistance sections;
Installation is simple and direct for product package without using additional assemblies and materials;
The anodes and pipelines are laid at the one time and in the same ditch, which is simple for both construction and installation; in addition, considerable reduction of current leakage improves the utilization efficiency of protective current.
Installation methods:
Cable traction laying
Laid in ditches
Laid at the bottom of tanks or on the sand layer between tanks
