Steel Pipe Inner Wall Liquid Epoxy Anti‑Corrosion Coating Production Line

Price Negotiable
Price: 1000000 usd
MOQ: 1 set
Delivery Time: 2-3 months
Brand: HUASHIDA
Product Description
  • Provides custom‑tailored anti‑corrosion solutions for steel pipe inner‑wall protection with high‑efficiency operation
  • Adopts mature high‑pressure airless spraying technology for uniform and full‑coverage internal epoxy coating
  • Finished lining features great adhesion, superior chemical resistance and ultra‑smooth surface
  • Lowers pipe inner roughness and flow resistance; avoids medium contamination & internal scaling
  • Significantly extends pipeline service life and reduces long‑term O&M expenses
  • Applicable for oil‑gas pipelines, water supply‑drainage pipes and various industrial process steel pipes

Core Functional Advantages

1. Long-Term Reliable Corrosion Protection The intact epoxy coating completely isolates the steel substrate from transported media including oil, gas and water, effectively preventing chemical and electrochemical corrosion, and providing stable long-term anti-corrosion protection for pipelines.
2. Improved Fluid Transportation Efficiency The ultra-smooth coated inner wall minimizes surface roughness and greatly reduces fluid friction resistance, optimizing pipeline conveying efficiency and saving long-term operating energy consumption.
3. Excellent Anti-Fouling & Anti-Scaling Performance The dense and non-stick coating surface inhibits dirt adhesion, medium contamination and internal scale and deposit formation, keeping the pipeline interior clean and stable for long-term operation.
4. Full-Life-Cycle Cost Optimization By enhancing pipeline corrosion resistance and anti-fouling capability, the equipment significantly extends pipeline service life, reduces frequent maintenance and replacement frequency, and realizes substantial full-life-cycle cost savings.

Professional Coating Structure & Standard Process Flow

1. Precision Abrasive Blast Cleaning Professional internal shot blasting treatment is implemented on pipe inner walls to reach standard Sa 2.5 surface cleanliness. This removes rust, oxide and impurities completely, and forms a uniform anchor pattern on the metal surface, ensuring maximum adhesion and bonding strength for the subsequent coating layer.
2. High-Precision High-Pressure Airless Spraying High-performance liquid epoxy primer is uniformly sprayed on the pipe inner wall via high-pressure airless spraying technology. The formed primer layer is dense, smooth and firmly bonded, building a solid primary anti-corrosion barrier for the pipeline.
3. Customizable Functional Topcoat (Optional) According to actual working conditions and customer demands, customized functional topcoats with wear resistance, anti-fouling and special medium resistance can be additionally applied to further upgrade the comprehensive protective performance of the coating system.
4. Constant-Temperature Thermal Curing The coated pipes pass through professional curing oven for integral thermal curing. The coating forms a continuous, intact and compact protective lining with stable physical and chemical properties, realizing permanent and reliable inner wall protection.
