Products Application field

Tubular anodes for cathodic protection

In cathodic protection, tubular titanium anodes have a wide range of applications

Cathodic protection of pipes and tanks

(1) Pipelines in soil: Pipelines are susceptible to corrosion in soil environments. By installing tubular titanium anodes near the pipeline and connecting them to a cathodic protection system, the pipeline can be effectively protected from damage due to corrosion. The high corrosion resistance and long life of tubular titanium anodes make them ideal for this application.

Tubular titanium anodes can be arranged inside or outside the tank to reduce the risk of corrosion through a cathodic protection system.

Ocean engineering

(1) Offshore platforms: In the marine environment, metal structures such as offshore platforms face the dual threats of seawater corrosion and marine biological attachment. Tubular titanium anodes can not only provide effective cathodic protection, but also adapt to the seawater environment by adjusting the composition of the oxide coating.
(2) Subsea pipelines: Subsea pipelines are an important part of marine oil and gas transportation, but they are easily corroded due to long-term immersion in seawater. The application of tubular titanium anodes can effectively extend the service life of submarine pipelines.

Products Service life

Tubular anode Service life

Because tubing is affected by many factors, including application environment, operating conditions, coating quality, substrate selection and maintenance status.

Factors affecting the service life of Tubular anodes

1. Application environment:
① Different media (such as soil, fresh water, sea water, etc.) have different degrees of corrosion on titanium anodes, thus affecting their service life.
② Chemical substances, temperature, pressure and other factors in the medium will also affect the performance of titanium anodes.
2. Operating conditions:
① Working current density is one of the key factors affecting the service life of titanium anodes. Under high current density, the consumption rate of the anode will increase, thereby shortening the service life.
② The way the anode is used (such as continuous use or intermittent use) will also affect its life.
3. Coating quality and substrate selection:
① The type, thickness, uniformity and bonding strength of the coating material will affect the corrosion resistance and service life of the titanium anode.
② Factors such as the purity, grain structure and mechanical properties of the titanium substrate will also affect the overall performance and service life of the anode.
4. Maintenance status:
Regular inspection, cleaning and maintenance of titanium anodes can extend their service life.

Under ideal working conditions (such as low current density, mild medium, etc.), the service life of titanium anodes can reach decades.
In harsher environments (such as high current density, highly corrosive medium, etc.), the service life of titanium anodes may be shortened to a few years or even shorter.

Product technical requirements

(1) Material requirements: The titanium anode substrate should be made of titanium materials that meet the standards, and the precious metal solution used for the coating should also meet the relevant standards.
(2) Dimensions: The dimensions of the titanium anode tube should meet the specified requirements, and the allowable deviation is determined by negotiation between the supplier and the buyer.
(3) Surface quality: The surface of the titanium anode should be free of pollution and debris. Minor scratches and abrasions are allowed, but they must be within the specified range.
Bonding strength: The coating and the substrate should be firmly bonded without peeling.
(4) Strengthening life: Under the specified current density, the total charge density of the titanium anode surface strengthening life test should meet the requirements of the order.
