ARO powder for jacking pipe About

Specially used for external protective coating of jacking pipe construction, it can also be applied on FBE coating to improve the wear resistance and impact resistance of FBE external coated steel pipe. It has the excellent adhesion and cathodic stripping resistance of single-layer FBE coating and the ultra-high hardness and ultra-high wear resistance of double-layer FBE coating.

The coating complies with SY/T 0315-2013 and GB/T39636-2020 standards.

According to different design requirements, the thickness of one coating can reach 800-1000m for ordinary grade and 1500m for reinforced grade.
It does not need to be used with any coating, and can be used alone as the outer protective layer of the steel jacking pipe.
The extremely low surface friction coefficient reduces the resistance of jacking construction.
It still has high flexibility (-30, 30 bending without cracking) at high coating thickness (1000m).
Cathode stripping (-1.5V, 65, 48h) 5mm.
Abrasion resistance (1000g/1000r, CS-17) 50mg; or sand fall abrasion resistance (L/m) 3L.
Adhesion (pulling method) 20MPa.
The thickness of one-time curing coating can exceed 1500m.
The maximum operating temperature can reach 90.

Superior Abrasion and Corrosion Resistance

ARO Powder is formulated to safeguard pipes during the challenging jacking process, delivering top-tier abrasion and corrosion resistance. By forming a robust protective overlay, it extends the life of pipelines even in harsh environments. The excellent adhesion and high-impact tolerance ensure reliable long-term performance, making it a preferred choice for infrastructure applications.

Versatile Application Methods and Fast Curing

Suitable for both electrostatic spray and fluidized bed techniques, ARO powder provides flexibility in industrial application. It cures quickly at temperatures between 180C and 220C, allowing for an efficient coating process and optimal film formation. The powder form simplifies handling and storage, and the product is supplied in secure HDPE packaging to maintain quality.

Broad Color Range and Compliance with Global Standards

Available in multiple colors such as orange, gray, yellow, brown, blue, and violet, ARO powder meets aesthetic and functional requirements. It conforms to established international standards including DIN, AWWA, and ISO, ensuring it meets quality and performance benchmarks for pipeline projects worldwide.

FAQ's of ARO powder for jacking pipe:

Q: How is ARO powder applied to jacking pipes?

A: ARO powder is commonly applied through electrostatic spray or fluidized bed processes. Both methods ensure an even distribution of the powder onto the pipe's surface, followed by a curing process at 180C to 220C, resulting in a uniform, durable protective coating.

Q: What benefits does ARO powder provide during pipe jacking operations?

A: ARO powder offers superior abrasion and corrosion resistance, protecting pipes against mechanical wear and harsh environmental conditions during jacking. The high impact resistance (>15 Joules) and excellent adhesion extend pipe lifespan and minimize maintenance needs.

Q: When should ARO powder be used for pipeline projects?

A: ARO powder is ideally used when enhanced protection is required for pipes subjected to mechanical stress or corrosive environments, especially during the pipe jacking process or for long-term corrosion protection in buried and exposed pipelines.

Q: Where should ARO powder be stored before use?

A: The powder should be stored in a cool, dry place away from sunlight, in its original sealed packaging. Proper storage ensures the product maintains its performance qualities for up to 12 months from the date of manufacture.

Q: What are the available pack sizes and types for ARO powder?

A: ARO powder is available in 20 kg or 25 kg pack sizes, supplied in either HDPE bags or drums. These packaging options maintain product integrity and facilitate safe handling and transportation.

Q: How does the curing process of ARO powder contribute to its performance?

A: Curing the powder at the specified temperatures (180C-220C) ensures it develops into a dense, tough coating with film thickness between 300-700 microns. This activation optimizes adhesion and resistance properties, crucial for pipeline longevity.

Q: What makes ARO powder a reliable choice for industrial pipeline coating?

A: ARO powder stands out due to its excellent abrasion and corrosion resistance, color options, compliance with ISO and DIN standards, and industrial-grade formulation, making it a dependable solution for demanding pipeline applications.
