Details Introduction
The inner wall epoxy powder coated steel pipe is a steel-plastic composite pipe made by using welded steel pipe as the base material and adopting processes such as double pretreatment of sandblasting and chemical treatment, preheating, inner coating, curing and post-treatment. It has excellent comprehensive performance, strong corrosion resistance and mechanical properties, good chemical stability and water resistance, and has the functions of reducing resistance, anti-corrosion, pressure resistance and antibacterial. It is generally not restricted by the conveyed medium, and the coating has a very strong bonding force with steel. Coating material: Epoxy powder (EP). It is suitable for working environments below 80℃. The steel pipe coating has extremely high adhesion. Its coating hardness is high, impact resistance is good, and it has good chemical corrosion resistance.
The production and processing range of internal and external epoxy powder anti-corrosion steel pipes is φDN80-ODN3500
Inner and outer epoxy resin paint anti-corrosion steel pipe/inner and outer epoxy powder composite pipe
Inner and outer plastic-coated pipes, inner and outer plastic-coated steel pipes are made by melting a layer with a thickness of 0.5 to 0.5 on the inner wall of the steel pipe
Steel-plastic composite pipes composed of organic substances such as 1.0mm polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP), or non-toxic polyvinyl chloride (PVC) not only possess the advantages of steel pipes, such as high strength, easy connection, and resistance to water flow impact It also overcomes the shortcomings of steel pipes such as easy corrosion, pollution and scaling when exposed to water, as well as the low strength and poor fire performance of plastic pipes. The design life can reach 50 years. The main drawback is that it cannot be bent during installation. When performing operations such as hot working and electric welding cutting, the cutting surface should be coated with non-toxic room-temperature curing adhesive provided by the manufacturer.
Operational versatility characterizes contemporary epoxy powder spraying equipment, with configurations available for both manual operation and fully automated production lines. Manufacturers have developed specialized solutions accommodating various workpiece sizes and production volumes, from compact units for small components to large-scale conveyorized systems for industrial fabrication. The equipment's compatibility with diverse epoxy powder formulations enables applications across multiple industries including automotive components, electrical enclosures, furniture, and architectural elements. This flexibility allows manufacturers to implement coating solutions tailored to specific product requirements and production parameters.
From an environmental perspective, epoxy powder spraying equipment offers sustainable advantages compared to traditional solvent-based coating technologies. The process eliminates volatile organic compound emissions associated with liquid coatings, supporting cleaner manufacturing operations and reduced environmental impact. The closed-loop powder recovery systems minimize waste generation while energy-efficient curing ovens contribute to lower operational carbon footprints. These ecological benefits, combined with the durable, high-quality finishes achieved through proper application, position epoxy powder spraying as a environmentally preferable coating solution for manufacturers addressing both performance requirements and sustainability objectives.
