Coated Steel Pipes

High-Performance Coated Steel Pipes – Advanced Anti-Corrosion Solutions

As an industry-leading manufacturer, FOREVER STEEL provides high-integrity Coated Steel Pipes engineered to withstand the most aggressive soil and marine environments. By integrating premium base pipes (SMLS, LSAW, ERW, SSAW) with state-of-the-art coating technologies, we ensure a service life exceeding 30–50 years for critical global infrastructure.

Technical Specifications & Dimension Range

Our coating facility handles a wide spectrum of pipe dimensions to meet diverse project scales:

Outside Diameter (O.D.): 2"–120" (60.3mm–3048mm)

Wall Thickness (W.T.): 3mm–60mm

Base Pipe Options: Seamless (SMLS), Longitudinal Welded (ERW/LSAW), Spiral Welded (SSAW).

Length: Single pipe up to 12.5 meters (Custom lengths available for specialized piling or transmission).

Advanced Coating Systems & Protection Standards

We offer multi-layer protection systems compliant with the most stringent international anti-corrosion standards:

External Coatings:

3PE (3-Layer Polyethylene): Compliant with DIN 30670, CAN/CSA Z245.21.

FBE (Fusion Bonded Epoxy): Single or Dual Layer, compliant with AWWA C213, API RP 5L7.

3PP (3-Layer Polypropylene): Ideal for high-temperature environments, compliant with DIN 30678.

Coal Tar Enamel/Epoxy: Compliant with AWWA C203/C210.

Internal Linings:

Liquid Epoxy: Reduces friction and enhances flow efficiency (API RP 2L).

Cement Mortar Lining (CML): Compliant with AWWA C205, ideal for water utilities.

Material Compliance & Global Standards

All base pipes and coating materials are strictly sourced and processed under ISO 9001 quality management:

Steel Grades: API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80; ASTM A53; ASTM A106; EN 10219 (S355J2H).

Manufacturing Standards: API 5L (PSL1/PSL2), ASTM A252, AWWA C200, AS/NZS 1579.

Professional End Preparation

To ensure superior weld integrity and coating continuity during field jointing:

Cut-Back Area: Standard 100mm–150mm uncoated ends (customizable) for ease of on-site welding.

Bevelled Ends: Precisely machined to 30°(+5°/-0°) per ANSI B16.25, protected by temporary anti-rust varnish or tape.

End Protection: Heavy-duty plastic caps or steel rings to prevent internal contamination and bevel damage.

Critical Industry Applications

Our coated solutions are the benchmark for durability in:

Energy Infrastructure: Long-distance oil, gas, and jet fuel transmission pipelines.

Water Management: Desalination plants, municipal water supply, and high-pressure sewage systems.

Marine & Piling: Offshore piling, bridge foundations, and harbor construction in high-salinity environments.

Quality Assurance & Technical Documentation

Holistic Testing: 100% Spark Leakage (Holiday) Testing, Adhesion (Peel) Tests, Impact Resistance, and Coating Thickness Verification.

Traceability: Mill Test Certificates (MTC) issued according to EN 10204 3.1.

Project Compliance: Full provision of ITP (Inspection and Test Plan) and MPS (Manufacturing Procedure Specification) for international tenders.

Export Packaging & Logistics Strategy

We prioritize the integrity of the coating layer during international transit:

Handling: Strict use of nylon lifting slings and rubber-padded hooks to prevent coating scarring.

Packaging: Padded bundling for small pipes; large diameter pipes use specialized rubber separators and timber dunnage to avoid steel-on-steel contact.

Shipping: Expert sea-worthy lashing in containers or bulk vessels; Third-Party Inspection (SGS/BV) is mandatory before shipment to ensure "Zero-Defect" delivery.
