For metal pipes, protection may combine coatings, cathodic protection, sacrificial anodes, dielectric joints, and electrical monitoring; for pipes made of concrete, FRP, HDPE, or other materials, protection focuses on chemical durability, watertightness, abrasion resistance, joints, and environmental compatibility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In projects of <a href=\"https:\/\/eurohinca.com\/en\/pipe-jacking-2\/\">pipe ramming<\/a>, <a href=\"https:\/\/eurohinca.com\/en\/subway-terrestrial-applications\/\">above-ground and underground microtunnels<\/a>, <a href=\"https:\/\/eurohinca.com\/en\/submarine-emissaries\/\">submarine emissaries<\/a> o <a href=\"https:\/\/eurohinca.com\/en\/sea-water-catchments\/\">sea water catchments<\/a>, corrosion protection must be determined before selecting the piping, joints, installation system, and acceptance procedure.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is considered a harsh environment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A medium or environment is considered aggressive to a pipe when it can accelerate corrosion, degrade the material, or reduce the pipe's service life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most relevant factors are:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Constraint<\/th><th>Why It Matters<\/th><\/tr><\/thead><tbody><tr><td>Chlorides<\/td><td>They increase the risk of corrosion, especially in marine or saline environments<\/td><\/tr><tr><td>Sulfates<\/td><td>They can affect cementitious materials and certain types of concrete<\/td><\/tr><tr><td>Low soil resistivity<\/td><td>It is often associated with an increased risk of corrosion in metal pipes<\/td><\/tr><tr><td>Acidic or highly alkaline pH<\/td><td>It can accelerate chemical attacks or damage coatings<\/td><\/tr><tr><td>High water table<\/td><td>It maintains humid conditions and promotes electrochemical processes<\/td><\/tr><tr><td>Seawater or brackish water<\/td><td>Increases exposure to chlorides, salts, and moisture cycles<\/td><\/tr><tr><td>Wandering Currents<\/td><td>They can accelerate corrosion in buried metal pipes<\/td><\/tr><tr><td>Differential oxygen<\/td><td>It can cause localized corrosion cells<\/td><\/tr><tr><td>Sulfate-reducing bacteria<\/td><td>They can contribute to microbiological corrosion<\/td><\/tr><tr><td>Internal or external abrasion<\/td><td>It may damage coatings or protective surfaces<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">For steel structures in offshore environments or immersed in seawater or brackish water, ISO 12944-9 establishes performance requirements for coating systems in corrosivity categories CX and immersion category Im4.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Protection Based on Pipe Material<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Pipe Material<\/th><th>Main Risk<\/th><th>Standard Protection<\/th><\/tr><\/thead><tbody><tr><td>Steel<\/td><td>External corrosion, internal corrosion, pitting, stray currents<\/td><td>Exterior coating, cathodic protection, joint inspection, interior coating if applicable<\/td><\/tr><tr><td>Ductile iron<\/td><td>Corrosion of the base metal and joints<\/td><td>Exterior\/interior coatings, sleeves, cathodic protection for demanding applications<\/td><\/tr><tr><td>Reinforced concrete<\/td><td>Attack by sulfates, chlorides, carbonation, and reinforcement corrosion<\/td><td>Durable concrete design, sufficient cover, appropriate cements\/strength grades, watertight joints<\/td><\/tr><tr><td>FRP<\/td><td>Chemical Compatibility, Abrasion, Deformation, and Joints<\/td><td>Resin selection, inner liner, stiffness class, abrasion protection<\/td><\/tr><tr><td>HDPE<\/td><td>Chemical compatibility, scratching, deformation, temperature, and buoyancy<\/td><td>Selection of PE, SDR, mechanical protection, installation inspection, and ballast, if applicable<\/td><\/tr><tr><td>Jacketed pipe<\/td><td>Corrosion on the carrier, sleeve, or contacts<\/td><td>Centers, dielectric separation, sealing, drainage, or annular venting<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The selection must be coordinated with the <a>High-strength pile pipe grade and joint type<\/a>, because corrosion protection must not compromise thrust capacity, sealing, angular capacity, or installation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Corrosion Protection Systems<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Exterior cladding<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">External coatings insulate the piping from the ground or water. For metal pipes, epoxy systems, polyurethane, three-layer polyethylene, tapes, mortars, special paints, or other systems compatible with the project may be used.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following must be verified:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Environmental compatibility.<\/li>\n\n\n\n<li>Mechanical strength during driving or installation.<\/li>\n\n\n\n<li>Coating continuity.<\/li>\n\n\n\n<li>Protection of joints and ends.<\/li>\n\n\n\n<li>Repairability on-site.<\/li>\n\n\n\n<li>Thickness and adhesion.<\/li>\n\n\n\n<li>Resistance to abrasion and damage caused by handling.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">ISO 12944-5 provides guidelines for selecting protective coating systems based on the environment, surface preparation, and expected durability, although it excludes cases CX and Im4, which are specifically addressed in ISO 12944-9.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Cathodic protection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In buried or submerged metal pipelines, cathodic protection can be used to reduce external corrosion through the use of sacrificial anodes or impressed current. Its feasibility depends on electrical continuity, soil or water resistivity, coating, electrical interference, length, accessibility, and service life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The AMPP NACE SP0169-2024 standard addresses the control of external corrosion in buried or submerged metal piping systems, including external coatings, cathodic protection, electrical current, installation, stray currents, and inspection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Protection of joints and connections<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Joints are critical points because they can disrupt coatings, create electrical discontinuities, trap moisture, or be exposed to leaks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following are reviewed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Seal integrity.<\/li>\n\n\n\n<li>Chemical compatibility of the elastomer.<\/li>\n\n\n\n<li>External protection for the plug or connector.<\/li>\n\n\n\n<li>Electrical continuity if cathodic protection is required.<\/li>\n\n\n\n<li>Dielectric insulation if materials need to be separated.<\/li>\n\n\n\n<li>Angular capacity in curved drives.<\/li>\n\n\n\n<li>Damage caused during pushing, dragging, or assembly.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Interior finishes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When the fluid being transported is corrosive\u2014such as seawater, brines, wastewater, industrial fluids, or effluents containing corrosive gases\u2014an internal lining or the selection of a compatible material may be required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following are analyzed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>pH of the fluid.<\/li>\n\n\n\n<li>Chlorides and sulfates.<\/li>\n\n\n\n<li>Temperature.<\/li>\n\n\n\n<li>Presence of H\u2082S or other gases.<\/li>\n\n\n\n<li>Abrasion caused by sand or solids.<\/li>\n\n\n\n<li>Traffic speed.<\/li>\n\n\n\n<li>Operating pressure.<\/li>\n\n\n\n<li>Need for cleaning or maintenance.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5. Separation, centering, and sealing in sleeves<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When the carrier pipe is installed inside a driven casing, corrosion protection also depends on the physical separation between the two components. Centering devices, skids, and seals prevent direct contact, damage to the lining, and uncontrolled accumulation of water or solids.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In these cases, coordination is required with the design of <a>Installation and alignment of the carrier pipe within a driven casing<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Design Changes in Marine Environments<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In marine or coastal environments, the risk increases due to the presence of chlorides, brackish water, tides, persistent moisture, salinity, oxygen, currents, biofouling, and potential damage during installation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At <a href=\"https:\/\/eurohinca.com\/en\/submarine-emissaries\/\">submarine emissaries<\/a>, <a href=\"https:\/\/eurohinca.com\/en\/sea-water-catchments\/\">sea water catchments<\/a> o <a href=\"https:\/\/eurohinca.com\/en\/crossings-of-marine-protected-areas\/\">crossings of marine protected areas<\/a>, the protection must take into account:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Exposure to buried, submerged, or intertidal conditions.<\/li>\n\n\n\n<li>Seawater or brackish water.<\/li>\n\n\n\n<li>Chlorides and sulfates.<\/li>\n\n\n\n<li>Ocean currents.<\/li>\n\n\n\n<li>Sediment abrasion.<\/li>\n\n\n\n<li>Impacts During Installation.<\/li>\n\n\n\n<li>Joint protection.<\/li>\n\n\n\n<li>Ballast, buoyancy, and stability.<\/li>\n\n\n\n<li>Short service life and difficult maintenance.<\/li>\n\n\n\n<li>Environmental Conditions and Permits.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In these environments, durability must be considered as a comprehensive system: material, coating, joints, cathodic protection (if applicable), installation, inspection, and maintenance plan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is monitored during manufacturing, transportation, and installation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Corrosion protection may fail if it is damaged before the equipment is put into service. That is why the following are inspected:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Surface preparation.<\/li>\n\n\n\n<li>Coating thickness.<\/li>\n\n\n\n<li>Adherence.<\/li>\n\n\n\n<li>Continuity of the lining.<\/li>\n\n\n\n<li>Damage repair.<\/li>\n\n\n\n<li>Edge protection.<\/li>\n\n\n\n<li>Handling and Lifting.<\/li>\n\n\n\n<li>Support and supplies.<\/li>\n\n\n\n<li>Compatibility with centering devices or skids.<\/li>\n\n\n\n<li>Joint protection.<\/li>\n\n\n\n<li>Leak or pressure tests.<\/li>\n\n\n\n<li>Electrical continuity, if applicable.<\/li>\n\n\n\n<li>Record of inspections and repairs.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In trenchless projects, this check is especially important because once the pipe is installed, access to it may be limited.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Risks of Insufficient Protection<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Insufficient corrosion protection can lead to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Loss of metal thickness.<\/li>\n\n\n\n<li>Pitting or localized corrosion.<\/li>\n\n\n\n<li>Leaks.<\/li>\n\n\n\n<li>Damage to joints.<\/li>\n\n\n\n<li>Coating degradation.<\/li>\n\n\n\n<li>Corrosion under insulation or under damaged coating.<\/li>\n\n\n\n<li>Stray-current corrosion.<\/li>\n\n\n\n<li>Domestic chemical attack.<\/li>\n\n\n\n<li>Reduced service life.<\/li>\n\n\n\n<li>More maintenance.<\/li>\n\n\n\n<li>Environmental risk in critical pipelines.<\/li>\n\n\n\n<li>Operational incidents involving outfalls, intake structures, or service networks.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, protection must be incorporated from the design phase and not added at the end as a generic coating.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Information Required for Design or RFQ<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To determine the corrosion protection required for a pipeline in aggressive soils or marine environments, the following information should be provided: pipe material, diameter, wall thickness, length, end use, fluid being transported, internal pressure, temperature, required service life, geotechnical conditions, water table, soil resistivity, pH, chlorides, sulfates, salinity, presence of H\u2082S, stray currents, buried or submerged environment, joint type, proposed coating, planned cathodic protection, accessibility for inspection, installation method, risk of abrasion, environmental requirements, final testing, and quality documentation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Request a <a href=\"https:\/\/eurohinca.com\/en\/request-offer\/\">Technical review of corrosion protection for driven, pressure, or marine pipelines<\/a> before selecting
