1. What is black powder coated steel pipe?
Black powder coated steel pipe is a black steel pipe with a metal surface coated with powder. This powder can extend the life and corrosion resistance of the black steel pipe, making the metal tube more beautiful and durable, so it is widely used in all walks of life.2. What is the black coating on steel pipe?
The powder used in the coating process is typically composed of finely ground particles of various materials.These metal powder coatings are mainly made of epoxy resin, polyester resin and additives such as curing agents, leveling agents, pigments, fillers, etc.These polymers are combined with pigments to achieve the desired black color. The powder coating is applied to the surface of the steel pipe electrostatically or via fluidized bed dipping, and then cured under heat to create a tough, durable finish.A common black powder-coated metal pipe is epoxy coated black iron pipe.
The composition of epoxy resin anti-corrosion steel pipe
① Steel pipes: seamless steel pipes, straight seam steel pipes, spiral steel pipes and other steel pipes.
② Epoxy resin coating, this product is a two-component, high-solid coating made of epoxy resin as the main agent. Divided into primer and topcoat. Component A consists of epoxy resin, pigments, additives, and auxiliaries, while Component B is a curing agent formulated with modified amines.
3.Characteristics of black powder coated steel pipe
(1) Corrosion resistance, long lifeThe cured epoxy resin powder coating film is tough and water-resistant, non-toxic, and does not pollute water. It has strong and good adhesion between the paint film and the paint film, which ensures the durability and life of the black steel pipe.
(2) Wide range of uses
Coated black pipes find numerous applications across various industries due to their durability, corrosion resistance, and aesthetic appeal. This coated steel pipe is suitable for domestic, commercial water delivery systems, HVAC (Heating, Ventilation, and Air Conditioning) systems, industrial applications and home improvement.
(3) Beautiful appearance
Black powder coated steel pipe has a beautiful appearance, which improves the decorative and visual effects of the pipe.
4. Can black powder coated steel pipe be welded?
Yes, powder coated steel pipe can be welded, but it requires some additional preparation.However, the powder coating in the welding area needs to be removed before welding the steel pipe. This is because the high temperature of welding will cause the powder coating to burn, release smoke and may contaminate the weld.
5.How to clean black powder coated metal?
To remove the powder coating on black steel pipes, you can use the following two methods.(1) Mechanical removal
Use a grinding wheel and wire brush to physically clean the welding area. When cleaning, you need to wear safety protective tools, such as glasses, gloves and masks.
(2) Chemical removal
Use a chemical cleaner to dissolve the powder coating on the black steel pipe, but be careful that the chemical will not hinder the subsequent welding work. At the same time, during the coating removal process, we must pay attention to protection to avoid harm to the human body.
