What are the principles and advantages of anti-corrosion steel pipes, and what are their coating requirements?

2022-11-07

With the increasing development of national pipeline transportation infrastructure, pipelines have found widespread application. Coating is one of the fundamental methods for preventing corrosion of steel pipes. After removing rust from metal pipelines, the paint should be applied evenly and firmly to effectively isolate the pipe from various corrosive media. Let’s now take a closer look at the principles behind anti-corrosion steel pipes.

Anti-corrosion steel pipes are steel pipelines that have undergone special anti-corrosion treatment, effectively preventing or slowing down corrosion caused by chemical or electrochemical reactions during transportation and use. Combining the mechanical strength of steel pipes with the corrosion resistance of plastics, these pipes serve as underground metallic structures. To extend their service life, steel conduits and lead-sheathed aluminum cables typically feature an external anti-corrosion coating for protection.

There are three primary methods for classifying steel pipes: by manufacturing process, by shape, and by application. Manufacturing processes are typically divided into seamless and welded types. By shape, steel pipes can be categorized into standard round, square, and special types such as double-dimple pipes. As a special type of steel pipe, anti-corrosion steel pipes undergo specialized anti-corrosion treatments that effectively prevent or slow down chemical or electrochemical reactions and corrosion during transportation and use.

TPEP anti-corrosion steel pipe, also known as coated pipe, steel-composite pipe, or coated composite steel pipe, features an outer wall made by a hot-adhesive wrapping process that forms a three-layer anti-corrosion coating consisting of an underlying epoxy powder, an intermediate adhesive layer, and an outer polyethylene layer. The inner wall is protected by a hot-sprayed epoxy powder coating. After the steel pipe is heated to high temperatures, the powder is evenly applied to the pipe’s surface. As a result, this coating combines the advantages of both epoxy powder (FBE) coatings and polyethylene coatings. It can be widely used in various anti-corrosion engineering applications.

TPEP anti-corrosion steel pipe, fully known as internally fused epoxy and externally 3PE-coated anti-corrosion pipeline, uses a steel pipe as its base material. The outer wall is coated with a three-layer polyethylene anti-corrosion layer, while the inner wall is protected by a hot-melt epoxy resin powder. At high temperatures, this process forms a steel-plastic alloy layer. It is commonly referred to as TPEP anti-corrosion steel pipe.

TPEP anti-corrosion steel pipe, also known as coated pipe, steel-composite pipe, or coated composite steel pipe, features a three-layer anti-corrosion coating. The outer wall of the TPEP anti-corrosion steel pipe is coated using a hot-melt fusion winding process, consisting of a bottom layer of epoxy powder, an intermediate layer of adhesive, and an outer layer of polyethylene, forming a robust three-layer structure. The inner wall is protected by a hot-sprayed epoxy powder coating, where the steel pipe is heated to high temperatures before the powder is evenly applied onto its surface. As a result, this coating combines the advantages of both fused-bond epoxy (FBE) coatings and polyethylene coatings. It is widely applicable across various anti-corrosion engineering fields.

Before starting work on coated composite pipes, carefully read the drawings and make thorough preparations according to the specific methods outlined in the construction process and the detailed procedures of the construction plan. Many factors can affect the quenching quality of coated composite steel pipes; hot-dip galvanized pipes are prone to rusting, which can once again contaminate water bodies.

Plastic-coated composite pipes are products consisting of an inner and outer coating made of PE (modified polyethylene) hot-dip plastic or EP (epoxy resin), offering excellent corrosion resistance. At the same time, the coating itself possesses good electrical insulation properties and does not cause galvanic corrosion. They also exhibit low water absorption.
