Epoxy Resin Anti-Corrosion Steel Pipe
- Commodity name： Epoxy Resin Anti-Corrosion Steel Pipe
- 产品描述
-
Epoxy resin anti-corrosion steel pipe is a steel pipe based on steel pipe, which is coated with epoxy resin coating on its surface through a special process to form an anti-corrosion layer. The following is a specific introduction:
Product composition
Steel pipes are usually seamless steel pipes, straight seam steel pipes, or spiral steel pipes. Epoxy resin coating is a two-component, high solid coating, with component A consisting of epoxy resin, pigment, filler, and additives, and component B being a modified amine curing agent.
Performance characteristics
It has excellent durability, and the cured paint film is tough and water-resistant. Strong adhesion, tight bonding between paint films and between paint films and steel pipe surfaces. Outstanding rust and water resistance, and tough paint film with good wear and impact resistance. In addition,High solid content, thick coating, room temperature curing, no need for large baking equipment.
Specification parameters
The outer diameter is usually between 219mm and 1420mm, the wall thickness is between 6mm and 30mm, the coating thickness is generally between 0.5-1.0mm, and can be customized according to needs. The applicable temperature range is generally -30 ℃ -120 ℃.
Anti corrosion principle
The epoxy resin coating forms a dense protective film, isolating the steel pipe from the external corrosive medium, preventing oxygen, water, etc. from coming into contact with the steel pipe, thus playing a role in anti-corrosion. At the same time, the epoxy resin itself has good chemical stability,
Can resist corrosion from various corrosive substances.Processing technology
First, clean and remove rust from the surface of the steel pipe, then use high-pressure airless spraying or immersion coating methods to evenly apply epoxy resin coating on the surface of the steel pipe, and finally send it to a curing furnace for high-temperature curing to form an anti-corrosion layer.
Application areas
Widely used in high-rise building water supply and drainage, fire sprinkler, HVAC, cable internal and external anti-corrosion and other fields, also suitable for pipelines transporting corrosive media in petrochemical and marine engineering, and can be used for drinking water transportation,Because its coating is non-toxic and does not pollute water.
Connection method
groove connection, flange connection, bimetallic welding connection and other methods can be used. DN50-DN300 steel pipes can be connected with grooves, DN50-DN2000 can be connected with flanges, and DN100 and above can be connected according to the situation Choose bimetallic welding connection or direct welding.
