2022-08-08
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.
TPEP Anti-corrosion steel pipes, also known as coated pipes, steel-composite pipes, and coated composite steel pipes. The external surface of TPEP anti-corrosion steel pipes features a three-layer protective coating formed by hot-melt fusion winding: an inner layer of epoxy powder, an intermediate layer of adhesive, and an outer layer of polyethylene. The internal surface is protected by hot-spraying epoxy powder—after the steel pipe is heated to a high temperature, the powder is evenly applied onto the pipe’s surface. This coating combines the advantages of both fusion-bonded epoxy (FBE) coatings and polyethylene coatings, making it widely applicable across various anti-corrosion engineering fields.
TPEP The underlying structure consists of a three-layer anti-corrosion coating made up of an epoxy resin layer, an intermediate adhesive, and an outer polyethylene layer. The inner wall is coated with thermally sprayed epoxy powder, which is melted and fused onto the pipe surface at high temperatures, forming a steel-plastic alloy layer. Since you’re interested in using this product, you should also know that fusion-bonded epoxy powder-coated steel pipes come in two types: single-layer and double-layer. Compared to the single-layer type, the double-layer epoxy powder coating is an ideal choice for corrosion protection. Accordingly, its construction principle involves using a single-layer fusion-bonded epoxy powder as the primer and a modified fusion-bonded epoxy powder as the outer protective layer. This significantly enhances the performance of the anti-corrosion coating, enabling it to meet stringent requirements for high-temperature resistance, permeability resistance, and impact resistance. Therefore... TPEP The compatibility between the single-layer fusion-bonded epoxy powder coating and cathodic protection has been maintained. TPEP Currently, it is widely used in pipeline engineering fields such as petroleum, chemical industry, natural gas, heating, wastewater treatment, water sources, bridges, steel structures, seawater transportation, and piling.
In addition, use TPEP There is also some important information at this time. For example, TPEP For use in different working environments. To slow down or prevent chemical reactions of pipelines in external media, thereby mitigating erosion and degradation caused by electrochemical or microbial metabolic activities, a coating can be applied to their outer walls. 2 or 3 Layered polyethylene ( TPEP ), to achieve pipeline corrosion protection, TPEP The service life of the anti-corrosion pipe has been extended. 3-5 Twice. For users, what you need to know is that it has a double-layer... FBE The coating anti-corrosion system further enhances mechanical performance, improving the coating’s impact resistance, scratch resistance, high-temperature resistance, and high-temperature permeability. TPEP It still maintains a single layer. FBE Compatibility between the coating and cathodic protection—no cathodic protection barrier. Overall coating thickness. Between, with operating temperatures up to 115 ℃, therefore today’s launch TPEP It is also an anti-corrosion coating that can be applied to steel pipes of various diameters, elbows, specially shaped parts, and fittings. Large-diameter pipelines are coated internally. FBE And external PE Large-diameter domestic drainage pipes generally use internal coatings. FBE And external application PE This ensures that the internal coating of the anti-corrosion pipe is dense, smooth, and has excellent adhesion, while the external coating is tough, impact-resistant, and easy to handle.
