offshore Structure
Corrosion Control
Offshore structures represent large capital assets and are extremely costly to run. Located next to the sea or placed in deeper waters, these structures are subjected to hostile, corrosive, marine environments and require continuous preventive maintenance to ensure prolonged and safe operation.
Corrosion is one of the most damaging factors in offshore structures that can lead to significant damage and even catastrophic structural failure. The vast majority of severe marine corrosion is caused by the combined effects of the sun, temperature, atmospheric gases ( O2 & CO2 ), moisture and minerals (salt) contained in the air. To simplify corrosion control of structural steel of offshore structures, cathodic protection in conjunction with protective coatings is a popular method used in industry practice.
Offshore Platform Cathodic Protection System
Offshore platforms, often placed in deep water, serves as a base for drilling wells, rigs and extracting oil/gas from beneath the ocean floor. It houses specialized machinery, pipelines and storage facilities necessary for the extraction, processing and transportation of oil or gas. Control of corrosion on these complex structures is necessary for the economic development of oil and gas production, to provide safe support for working and living areas.
Wind Turbine Foundation Cathodic Protection System
To tackle climate change, offshore wind farm is poised to become a major asset for electricity generation in the transition away from harmful fossil fuels towards a cleaner, greener, less carbon-intensive energy future. Most offshore wind farms employ fixed-foundation wind turbines in relatively shallow water. These foundations are built with stability and resilience to withstand harsh marine environment and erosion corrosion.
Wharf & Jetty Pile Cathodic Protection System
The well-maintained wharf is a critical component of the waterway transport system. The wharf structures, such as piers, jetty piles, are constantly exposed to the direct impact of sea surface water and the presence of aggressive corrosive elements. To combat this issue, cathodic protection systems are commonly utilized to acts as a shield, safeguarding the piles from corrosion, thereby ensuring their prolonged service life.
onshore Structure
Corrosion Control
From steel reinforced concrete buildings, electrical transmission tower, to large scale solar farms, a wide range of onshore facilities need to operate efficiently for decades. To satisfy the high requirements of their owners, these valuable assets need to be protected against corrosion in accordance with the ambient conditions.
Onshore environments, particularly those in industrial and urban areas, are battlegrounds against corrosion due to their exposure to various corrosive elements, including harsh atmospheric conditions, environmental pollutants, aggressive chemistry in the soil, etc. To combat these challenges, cathodic protection is employed as an effective strategy that help protect assets and ensure their longevity. By utilizing the full range of products and methods developed by years of research, YUXI can reliably provides tailor-made solutions for every type of these assets.
Reinforced Concrete Structure Protection and Rehabilitation
Reinforced concrete is used in construction because of excellent durability, workability & high strength. However, concrete corrosion induced by chloride attack and carbonation really impacts the strength and integrity of the structure over time. When steel elements within the concrete structure corrode, the resulting rust expands and tends to proceed in a very specific form known as “pitting”. Cathodic protection is a technique used to prevent or reduce corrosion rates.
Photovoltaic Farmland Ground-Mounting Pile Corrosion Resistance
The scale and number of photovoltaic (PV) farms increase rapidly worldwide. Solar panels are generally mounted on galvanized steel piles that are embedded in the soil. One major concern for solar farm operator is the impact of subsurface corrosion on the service life of the steel piles. Cathodic protection system, using impressed current or sacrificial anodes, is recommended as a long-lasting approach to direct the chemical reaction (corrosion) elsewhere, away from the piles.
Transmission Tower or Lattice Power Pylon AC Mitigation
Electricity pylons, usually lattice towers, are the most common type for high-voltage transmission lines. When underground pipelines and overhead high-voltage electricity tower are co-located, they are subject to AC interference. AC-induced corrosion is a significant threat to integrity of buried pipelines, due to its very high localized corrosion rate. Thereby AC mitigation, achieved by installation of different grounding methods, is required to decrease the induced voltage on pipelines.
Pipelines
Corrosion Prevention
Metallic pipelines buried in the ground, submerged in the sea or exposed to seawater are at serious risk to corrosion and fouling. Corrosion of steel piping is a common process which is unfortunately difficult to counteract. Internal and external corrosion have been responsible for a high percentage of the significant incidents on pipelines transporting gas and liquid.
The type and rate of corrosion are closely dependent on factors such as the local soil resistivity and chemistry along the pipeline’s route, the transported substance composition, the operating pressure and temperature. Therefore, a combination of organic coatings and cathodic protection should be considered as the most widely used preventive method for controlling corrosion.
Underground Pipelines Cathodic Protection
External surfaces of pipelines, which are mostly fabricated from carbon steel, are prone inherently to be corroded by electro-chemical reactions with the environment. The buried pipes face an environment that can change due to climatic factor and soil conditions. Variations in these factors create a dynamic environment where protective measures must be adaptive and robust.
Submarine Pipelines Cathodic Protection
Severe buckling or corrosion may lead to subsea pipeline failures. Once the pipeline is seriously leaking, it will result in economic losses, as well as damaging the surrounding ecological environment. Thus, it is necessary to eliminate the potential threats at the earliest stage to ensure the safety. CP system is a popular method intended for protecting pipelines external surfaces from the corrosive effects of seawater.
Pipeline Internal Corrosion Prevention
Pipelines, carrying corrosive liquids or contaminants, are vulnerable to internal corrosion. Corrosion can lead to the gradual reduction of the wall thickness of the pipe, resulting in loss of strength. This loss can cause the pipeline to leak or rupture due to internal pressure stresses. Therefore, CP systems intended for internal corrosion control should be part of any newly built, below-grade pipeline design.
Storage Tanks
Corrosion Prevention
Corrosion in tanks, defined as the destruction of metal surface, is the deterioration process due to its physicochemical or chemical interaction with the environment. The external corrosion of the tank stains under the influence of atmospheric moisture and vapors of aggressive substances contained in the air. The inside corrosion culprit basically involves chemical composition of the substance stored.
Corrosion can lead to structural damage, leaks and contamination of the stored substance. To reduce the danger of corrosion damage to the metal frameworks, it is essential to implement a certain protection measures of rust and corrosion control. YUXI can provide numerous cathodic protection systems for any tank whether new build or existing retrofit.
Aboveground Storage Tank Floor Cathodic Protection
The soil-facing side of a tank bottom is highly susceptible to corrosion. The presence of inevitable gaps and crevices between the annular plates and the ring wall is a major source of corrosion around the tank’s base. Such spaces under the tank bottoms allow for the ingress of moisture and diffusion airborne chloride. ICCP system has been adopted as the most predominant method to mitigate soil-side corrosion of the tank base.
Underground Storage Tank Cathodic Protection
With more owners choosing to hide their propane tanks with popular underground installations, the need to protect steel tanks from moisture and chemicals in the soil has never been greater. Aggressive ions in the soil, such as chlorides and sulfates, can aggressively attack metal, hastening degradation. To minimize the rusting of tank exterior, cathodic protection system is widely applied as a complementary measure in conjunction with protective coating.
Water Tank Internal Surface Cathodic Protection
Water tanks are essential for storing and supplying clean water for various purposes. However, water tanks can develop corrosion of interior surface over time, due to chemical reactions with water and other substances. Corrosion not only affects the quality of stored water but also shortens the tank’s lifespan. Our cathodic protection system should be considered as a crucial technique for internal corrosion resistance.
Ship Hull
Corrosion Prevention
& Anti-fouling Solutions
The ship is continuously in contact with water and moisture laden winds which makes it highly susceptible to corrosion. Corrosion is one of the greatest enemies of the ship main body and its machinery — from the outer body to the smallest equipment used in operations.
We offers a wide range of anodes for cathodic protection of pleasure craft, river boats, canal boats, cruising boats and ocean going ships. They are ideally used to prevent corrosion of the hulls, propellers, rudders, shafts, ballast tanks, sea chests, buoys, etc.
Underwater Hull Corrosion Protection
By pairing zinc reference electrodes with mixed metal oxides coated disc anodes mounted below the water line, our impressed current cathodic protection system is designed to continuously monitor the level of protection and automatically adapt to the current required to avoid corrosion.
Marine Growth Prevention System (MGPS)
To protect and purify the surface of ship’s pipework and mechanical parts, electrolytic anti-fouling is regarded as the most economical way achieving marine biofouling protection. The anti foulants released by copper anode rods create an environment that discourages organisms to adhere and breed.
Propeller Shaft Grounding System
Earthing the propeller shaft to the ship’s hull prevents corrosion and spark erosion in the shaft bearings and gearboxes. The earthing is provided by spring loaded silver graphite brushes, and monitored by a compact mV meter. The system consists of a slip ring, brush holder, silver brush and voltmeter.
Wastewater Treatment
Known as liquid waste, wastewater is any water that has been used and tainted by humans, whether it be at home, in the factory or from other commercial premises. There are two different types of wastewater: sewage and industrial effluent. And all require their own treatment plans to ensure the treated water is environmentally safe to be released back into a natural water source.
As an alternative method to classic physical-chemical water treatment, electro-chemical water treatment is characterized as an advanced and economical treatment process to remove physical, chemical, and biological contaminants contained in the wastewater. Electro-oxidation, electro-reduction, and electro-coagulation are three fundamental methods. All electro-chemical processes take place at the electrodes while passing a direct electric current through the electrolyte solution.
Industrial Effluent Treatment
Industrial effluent is the dirty wastewater from non-residential sources generally require additional preliminary treatment steps than what is needed for sewage. As a combination process of electro-flotation and electro-precipitation, electro-flocculation is a water treatment technology of applying direct electrical current to treat and flocculate contaminants that are generally more difficult to remove by filtration.
Sewage Treatment
Sewage refers to the wastewater comes from domestic or municipal sources, which flows away through sewers. Our solutions for wastewater reuse and discharge focus on organic contaminants degradation, electro-chemical oxidation and filtration as well as removal of dissolved solids. With our combination of technologies, you are set to meet legal treatment requirements, all while minimising the operating costs.
Landfill Leachate Treatment
Landfill leachate is a very offensive liquid produced by the solid waste disposal in an aerobic environment. Due to complex chemical composition of leachate, the treatment of leachate is the most important concern for solid waste management. Nowadays electro-chemical processes present a way to treat leachate in an effective, relatively safe, and economically feasible manner.
Water Purification & Disinfection
Electro-chemical disinfection (ECD) — a method in which chemical oxidants are generated in situ via redox reactions on the surface of an electrode — has attained
growing acceptance in recent years as an alternative to traditional chemical dosing disinfection methods.
It has proven its reliability in several practical applications, mainly for the production of germ-free water and the disinfection of drinking water, swimming pool water, industrial cooling water, etc. To ensure the electro-chemical reaction effectiveness, titanium electrodes with platinum group metals are generally the best suited to water disinfection.
Seawater Desalination by Electrodialysis
Seawater desalination is an effective way to tackle water stress in arid coastal regions. Electro-dialysis technology is proven to be one of the promising membrane-based desalination processes to produce fresh water for drinking, irrigation, or industrial use. Electrodialysis utilizes electric potential to move the salts ions through pairs of charged selective membranes, which trap salt in alternating channels.
Cooling Tower Water Descaling
Limescale buildup, especially on heat transfer surfaces, can cause several problems, including reduced water flow, increased energy costs, and shortened life expectancy. To combat limescale accumulations and minimize biological deposits, the water descaler is adopted in basin water treatment system of central air-conditioning circulating cooling tower.
Swimming Pool Water Disinfection
Swimming pool sanitation is an important requirement for any pool owner. To maintain high levels of water quality, the bathing water needs continuous disinfection and sterilization. Owing to the side effects of conventional chemical disinfectants, electro-chlorination has emerged as the most popular non-chemical solution in recent years.
Energy & Chemistry
Characterized by two electrodes operating in the electrolyte solution, electrolysis is widely recognized as a high-performing solution for various electro-chemical processes. Especially in the case of frequent polarity reversal, the electrode material is required to be resistant to both oxidation and reduction.
Therefore, the less energy-intensive
electrode material with high stability is vital to ensure porcess efficiency and cost effectiveness. Due to its low chlorine evolution potential and high oxygen evolution potential, titanium-based electrodes are widely applied in reactor cell for large scale hydrogen production, chlor-alkali production and certain chemical products processing.
Green Hydrogen Production
As demand for clean and sustainable energy sources continues to grow, hydrogen is poised to play a significant role as an energy vector. Large-scale green hydrogen production by water electrolysis technology using a source of renewable energy emerges as one of the most promising option in the transition to a carbon-neutral economy.
Chlor-alkali Production
The chlor-alkali industry – in which chlorine and sodium hydroxide are produced by electrolytic decomposition of brine – has become the principal source of chlorine in modern chemical industry. The electrolyzing process in an membrane cell with positive and negatively charged electrodes is the most common and economical way preferred.
Electrolytic Organic Synthesis
The severe limitations of fossil fuels and finite resources influence the scientific community to reconsider chemical synthesis and establish sustainable techniques. Electro-organic conversion has attracted particular attention from international academia and industry as an environmentally benign and cost-effective technique.
Refinery & Manufacturing
As environmental concerns continue to gain prominence globally, the titanium-based electrodes have recently grown in popularity in key end-use industries, such as electronics, semiconductors, automotive, etc.
We provide advanced electrodes solutions in line with various industry requirements. Titanium-based electrode is a highly abundant and recyclable material, making it a sustainable choice for a wide variety of industrial electrochemical processes on a
huge scale.
Copper Foil Electrodeposition
The demand for high-grade copper foils has significantly increased in recent years for their excessive use in electronic appliances. Electro-deposited copper foil is manufactured by depositing copper ions, via electrolysis, onto a rotating titanium drum to form a thin film of high purity foil.
Electrometallurgy / Metal Electrowinning
Electrometallurgy is an important method used in metallurgy for extraction of metals from aqueous solutions by electrolysis. This electro-extraction (EE) process can be used in winning of metals from molten-salt solution (leaching) and purification of crude metals obtained via the hydrometallurgical routes.
Electroplating
Electroplating is a popular metal finishing and improving process used to prevent corrosion of metal or for decorative purposes. Regarded as an insoluble anode for long-term use, our titanium anode coated with noble metal oxides is applied in various electroplating operations, such as gold plating, chrome plating, copper plating, nickel plating, and zinc plating.
