TOBO Coated Steel Pipe: Delivering Durability to ASME Standard

TOBO Coated Steel Pipe: Delivering Durability to ASME Standard

TOBO Coated Steel Pipes represent a critical advancement in infrastructure durability, designed to combat corrosion and significantly extend asset life in aggressive environments. Produced to exacting ASME standards for dimensional and material quality, these pipes undergo specialized surface treatment and application of high-performance barrier coatings. This process creates a formidable, long-lasting shield that protects the structural steel core from moisture, chemicals, and abrasion. By integrating robust steel strength with advanced polymer science, TOBO delivers a piping solution that ensures project integrity, minimizes lifecycle costs, and provides reliable performance in buried, submerged, or industrial exposure applications.

1. Product Description
TOBO Coated Steel Pipes are manufactured from certified seamless or welded steel pipe, which serves as the structural substrate. The core product involves a meticulous, multi-stage process: first, achieving a near-white metal surface cleanliness through abrasive blasting; then, applying a precisely controlled, factory-bonded protective coating. Our flagship systems include Fusion-Bonded Epoxy (FBE) for excellent adhesion and cathodic disbondment resistance, and 3-Layer Polyolefin (3LPE/3LPP) systems that combine epoxy adhesion with a polyolefin layer for superior mechanical protection.

2. Key Specifications

• Base Pipe: Compliant with ASME B36.10M and materials such as ASTM A53, A106, or API 5L.

• Coating Specifications: Applied per ISO 21809, ASTM A775, or AWWA C213 standards.

• Standard Coating Types: Single/Dual Layer FBE, 3-Layer Polyethylene (3LPE), 3-Layer Polypropylene (3LPP).

• Size & Thickness: Available for pipes from NPS 1/2" to 48", with coating thickness tailored to service conditions (e.g., 300-1000μm for 3LPE).

• Performance Temperature: Suitable for continuous operation within ranges specific to coating type, typically -40°C to 100°C for 3LPE and up to 140°C for 3LPP.

3. Application
These pipes are engineered for longevity in scenarios where failure due to corrosion is unacceptable:

• Oil & Gas Transmission: Primary choice for onshore and subsea cross-country pipelines, ensuring decades of service.

• Water & Utilities: Protection for municipal water mains, sewer force mains, and industrial water intake/outfall lines.

• Chemical & Process Industries: Used for underground piping networks and effluent lines handling corrosive soils or liquids.

• Infrastructure & Marine: Ideal for structural pilings, dock facilities, and coastal structures exposed to saltwater splash zones.

• Mining & Slurry Transport: Pipes with specialized abrasion-resistant linings or external coatings for harsh mining operations.

4. Key Advantages

• Superior Corrosion Immunity: Creates a continuous, non-conductive barrier that effectively isolates steel from electrolytes, drastically slowing the electrochemical corrosion process.

• Mechanical Resilience: Polyolefin coatings provide excellent resistance to impact, soil stress, and handling damage during transport and installation.

• Synergy with Cathodic Protection: FBE coatings are specifically designed to work efficiently with impressed current cathodic protection systems as a secondary defense.

• Lifecycle Economics: The initial investment is offset by dramatically reduced maintenance, repair, and replacement costs over the asset's extended lifespan.

• Quality Assurance: Factory-applied under controlled conditions ensures consistent thickness, complete coverage, and optimal adhesion, unlike field-applied coatings.

5. Function
The primary function of TOBO Coated Steel Pipes is to preserve the mechanical integrity of the pipeline system by preventing substrate corrosion. They act as the first and most critical line of defense, ensuring the safe, uninterrupted, and economical flow of contents. By preventing wall thinning and leaks, they protect the environment, ensure public safety, maintain operational capacity, and safeguard the significant capital investment embodied in pipeline infrastructure.
