Pipeline Internal Joint Derusting & Epoxy Coating Robot

l To meet the upgrading market demand for large-scale pipeline rehabilitation, our new-generation robot supports full internal pipeline rehabilitation. It realizes integrated operation of full-wall derusting, vacuum dust cleaning, epoxy spraying and quality inspection for long-distance water and oil pipeline renovation projects, such as 8-kilometer continuous pipeline internal treatment. It greatly improves project quality and creates high commercial added value for engineering contractors.

Two core models are available: liquid epoxy spraying robot and FBE powder spraying robot. We are the world’s exclusive manufacturer of professional FBE pipeline powder spraying robots, breaking long-term technical industry bottlenecks.

Core Technical Highlights

Sa2.5 Standard Shot Blasting Derusting Adopts advanced shot blasting technology instead of traditional sandblasting, stably meeting Saudi Aramco Sa2.5 cleanliness standard to ensure superior coating roughness and adhesion.

1km Long-Distance In-pipe Remote Operation Supports 1-kilometer automatic in-pipe shuttle spraying and automatic return. Real-time video, images and construction data are synchronously transmitted for quality monitoring and traceability.

Intelligent Fault Rescue & Safety Protection Automatic alarm for failure or low power. Equipped with dedicated rescue device to drag out the robot rapidly, avoiding equipment loss and construction delay.

One-stop Integrated Process Integrates derusting, vacuum dust cleaning, intermediate frequency heating and spraying, ensuring consistent and stable coating quality.

Dual Cooperation Modes Supports robot sales and on-site engineering cooperation for oil, gas and water pipeline projects, with full-process technical support and after-sales service.

Competitive Advantages

Exclusive FBE Powder Spraying Technology World-leading FBE robotic spraying capability, coating adhesion reaches above 5MPa.

Fully Automatic Closed-Loop Operation Full-process automatic control from derusting to curing, improving working efficiency by 30%.

Ultra-wide Adaptability Applicable to pipe diameter 114mm–4200mm, compatible with FBE powder and liquid epoxy, suitable for 3LPE/3LPP anti-corrosion projects.

Harsh Environment Durability Salt spray resistance up to 1000 hours, compliant with SY/T0457 and AWWA C210 international standards, adaptable for offshore, hydrogen energy and petrochemical pipelines.

Our pipeline rehabilitation robots serve high-end anti-corrosion projects across 23 countries, delivering efficient, stable and reliable pipeline repair solutions.
