Single-layer epoxy powder (FBE) and double-layer epoxy powder (2FBE) anti-corrosion for steel pipes

Single-layer epoxy powder (FBE) and double-layer epoxy powder (2FBE) anti-corrosion for steel pipes

Fusion-bonded epoxy (FBE) powder external coatings (FBE/2FBE) are a new type of anti-corrosion coating that has been developed over the past 30 years. FBE coatings come in two types: single-layer and double-layer. The term "FBE coating" typically refers to the single-layer fusion-bonded epoxy coating. The single-layer FBE coating uses a specialized fusion-bonded epoxy powder coating as its film-forming material. This epoxy powder coating is applied using an electrostatic spraying process, forming a continuous film in a single pass.

Fusion-bonded epoxy (FBE) powder coatings—also known as 2FBE—are a new type of anti-corrosion coating that has been developed over the past three decades. FBE coatings come in two types: single-layer and double-layer. The term "FBE coating" typically refers to the single-layer fusion-bonded epoxy coating. The single-layer FBE coating uses a specialized fusion-bonded epoxy powder coating as its film-forming material. This epoxy powder coating is applied via electrostatic spraying, forming a continuous film in a single pass. This epoxy powder coating is a thermosetting material, produced by mixing and grinding solid epoxy resin, curing agents, and various additives. Before painting, steel pipes undergo shot blasting and intermediate-frequency preheating. Then, using an electrostatic spraying method, the epoxy powder coating is applied onto the heated pipe surface, where it melts and bonds firmly to the pipe surface, subsequently curing to form a protective coating. Generally, FBE coatings have a single-coat film structure. FBE coatings offer numerous advantages, including strong adhesion to steel, excellent film integrity, resistance to cathodic disbondment, tolerance to soil stress and abrasion, simple application procedures, zero pollution, superior impact and flexural resistance, and high temperature resistance. As a result, they have been widely adopted abroad. FBE coatings can be used for external corrosion protection of steel underground pipelines or underwater pipeline facilities operating at temperatures ranging from -30°C to 100°C.

Steel pipe polypropylene 3PP anti-corrosion

Steel pipe polypropylene 3PP anti-corrosion

2PP/3PP Anti-corrosion Steel Pipe Specifications: Φ89mm–Φ3200mm Material: Q235B, Q345B, 10# Steel, 20# Steel, Grades X42–X80 Standards: SY/T7041-2016, DIN30678 Advantages of the Anti-corrosion Coating The three-layer polyethylene anti-corrosion coating combines the excellent properties of both epoxy coatings and extruded polyethylene coatings. It integrates the interfacial characteristics and chemical resistance of epoxy coatings with the mechanical protection features of extruded polyethylene coatings, significantly enhancing the performance of each component. Therefore, it serves as an outstanding external protective layer for buried pipelines. According to relevant data, the three-layer PE coating can extend the service life of buried pipelines up to 50 years and is currently recognized internationally as one of the most advanced pipeline external anti-corrosion technologies. In 3PE anti-corrosion systems, the three-layer PE coating has been first applied in oil and gas systems. The Shaanxi-Beijing natural gas pipeline and the Kuerle-Shanshan oil pipeline—both already completed in China—along with the nearly 4,000-kilometer West-to-East Gas Pipeline project, all utilize the three-layer PE external anti-corrosion coating. Additionally, the 67-kilometer high-pressure pipeline from Shaanxi to Tianjin, the 30-kilometer outer ring high-pressure natural gas pipeline, and the 122-kilometer pipeline of the Shaanxi-Beijing underground gas storage facility also employ the three-layer PE coating. As such, the three-layer PE coating has become the leading direction for the future development of external anti-corrosion coatings for pipelines. Applications: The product is widely used in oil pipelines, natural gas pipelines, heating pipelines, and water supply pipelines. Application Scope: Currently, China has not yet established an industry standard for 3PP coatings. Therefore, the 3PP anti-corrosion pipelines produced generally follow the German standard DIN30678 “Polypropylene Coatings for Steel Pipelines.” The 3PP coating is primarily used as an anti-corrosion layer for pipelines transporting media at relatively high temperatures, as well as for pipelines located in desert regions characterized by high surface temperatures and prolonged sunlight exposure. Consequently, it has gained increasingly widespread application on buried water, gas, and oil pipelines in areas with high surface temperatures and long periods of sunlight.

Applying fiberglass to the surfaces of carbon steel, concrete, or other substrates to prevent the substrate from being damaged or deteriorated under the influence of media or environmental factors is referred to as "fiberglass anti-corrosion." Commonly used fiberglass anti-corrosion techniques include: fiberglass lining, glass flake lining, resin mortar brick and tile lining, epoxy self-leveling coatings, epoxy powder spraying, and fiberglass coating applied directly onto the substrate surface.

Polyurea anti-corrosion coating for steel pipes

Polyurea anti-corrosion coating for steel pipes

The future development of polyurea-coated anti-corrosion steel pipes: Polyurea coatings represent the international trend in next-generation anti-corrosion technology. Currently, major pipeline companies worldwide have adopted polyurea anti-corrosion coatings—for instance, the oil pipelines in Alaska, USA; the Gulf oil pipeline in Indonesia; the Siberian oil pipeline in Russia; and the water transmission pipelines in Kuwait—all of which use polyurea as their anti-corrosion coating. Superiorities of Polyurea-Coated Anti-Corrosion Steel Pipes: Polyurea-coated anti-corrosion steel pipe materials exhibit excellent construction performance when used for pipeline joints. Typically, straight pipe sections are prefabricated in the factory, while joints are connected on-site via spray application. After polyurea treatment, the pipeline maintains outstanding continuity and integrity, ensuring that the entire pipeline system is completely sealed with no seams, thereby guaranteeing its overall anti-corrosion performance and ultra-long service life. Key Features of Polyurea-Coated Anti-Corrosion Steel Pipes: Fast curing speed, allowing for seamless application on vertical and curved surfaces without sagging; excellent corrosion resistance, capable of withstanding erosion by most chemical media; superior physical properties, providing strong adhesion to metal substrates; 100% solid content, non-polluting, and environmentally friendly; seamless coating, completely eliminating the risk of leakage points. Main Applications of Polyurea-Coated Anti-Corrosion Steel Pipes: Overhead pipelines, directly buried pipelines, oil pipelines, gas pipelines, municipal sewage pipelines, and various types of steel pipelines—both internal and external wall anti-corrosion. Future Development of Polyurea-Coated Anti-Corrosion Steel Pipes: Polyurea coatings represent the international trend in next-generation anti-corrosion technology. Currently, major pipeline companies worldwide have adopted polyurea anti-corrosion coatings—for instance, the oil pipelines in Alaska, USA; the Gulf oil pipeline in Indonesia; the Siberian oil pipeline in Russia; and the water transmission pipelines in Kuwait—all of which use polyurea as their anti-corrosion coating. According to international standards, all underground metal pipelines employ a combined protection approach involving an anti-corrosion coating and cathodic protection. Among these, the pipeline anti-corrosion coating serves as the primary barrier. The 3PE anti-corrosion coating, which integrates the advantages of high-density polyethylene wrapping and fusion-bonded epoxy powder, is now widely used. However, its main drawback—the unresolved issue of joint repairs—remains a challenge. The heat-shrink sleeves currently used do not match well with the 3PE coating, significantly reducing the service life of the system.
