MMO/Ti Wire Flexible Linear Anode
YUXI’s flexible MMO linear anode is a kind of anode which is prepackaged in a porous, non-woven fabric “sock” that contains high conductivity calcined petroleum coke breeze —— enhancing the abrasion and damage resistance. It improves the current distribution efficiency and helps prevent over-voltage problems such as hydrogen generation and associated rapid coating disbondment.
Our MMO linear anode consists of titanium wire coated with Ir-Ta mixed metal oxide catalyst, running in parallel with an insulated copper conductor. It is used for impressed current cathodic protection of buried structures, such as buried oil (gas) pipelines, underground tank, petrochemical container etc.
Description
—— Quality Copper Conductor ——
Our power cable delivers the required current over considerable distance without incurring substantial longitudinal voltage drop. The choice of the cable can be made from HMWPE, XLPE/PVC, Kynar/HMWPE or as per specification.
—— High-grade MMO Wire ——
The core of the anode is composed of high-tensile titanium wire, which meets ASTM B348 Grade I/II. The iridium-tantalum mixed metal oxide catalyst demonstrate high chemical stability for use in soil or fresh water, where low chloride ions present.
—— Tight Joint Sealing ——
The MMO wire and the copper conductor are crimped together. Besides, the connection joint is sealed in a splice kit with epoxy resin to prevent water intrusion — Helium Leak Test passed. Connections are nominally made at 5m(16.4 ft.) intervals to ensure uniform current distribution along the length of the anode. Different connection intervals can be accommodated as required.
—— Evenly Backfill Filling ——
—— Acid-resistant Braid Fabric Jacket ——
—— Reel Packing ——
Our MMO linear anode can be packed on wooden or steel reel as required. It is normally installed right from the factory provided reel into the trench for easy transportation.
—— Practical Application ——
Typical uses for YUXI’s MMO linear anode include the impressed current cathodic protection of in-plant piping, buried oil (gas) pipelines, petrochemical container, tank bottoms and other underground structures. The linear anode can be easily field cut to appropriate lengths, or it can be spliced to other segments. This tough anode can be buried directly in the soil. Thus it simplifies field installation and saves labor cost.
