Coated Steel Pipes

Forever Steel supplies coated steel pipes for buried pipeline, oil and gas transmission, water supply, mining slurry, industrial plants and marine-related corrosion-protection projects. Available coating systems include 3PE, 3LPE, FBE, liquid epoxy, 3PP and cement mortar lining, depending on the service environment, operating temperature, soil condition, pipe size and project specification.

Buyers usually need to confirm the base pipe standard, steel grade, outside diameter, wall thickness, coating standard, coating thickness, end cutback, holiday test requirement, adhesion test requirement, packing method and shipment documents before placing an order.

Coated steel pipe is normally selected when the base pipe needs additional protection against soil corrosion, moisture, chemical exposure, seawater influence or transport damage. Forever Steel supplies coated pipes based on seamless pipe, ERW pipe, LSAW pipe and SSAW pipe, with coating solutions matched to project specifications.

1. 3PE coated steel pipe for buried oil, gas and water transmission pipelines.
2. FBE coated steel pipe for internal or external corrosion protection.
3. Epoxy coated steel pipe for flow efficiency and anti-corrosion requirements.

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).

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

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.

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.

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.

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.

1. Base pipe type: seamless, ERW, LSAW or SSAW.
2. Standard and grade: API 5L, ASTM A53, ASTM A106, ASTM A252, EN 10219 or project standard.
3. Size: OD, wall thickness, length and quantity.
4. Coating system: 3PE, FBE, epoxy, 3PP or cement mortar lining.
5. Inspection: coating thickness, holiday test, adhesion test, MTC and third-party inspection.
6. Pipe ends, cutback length, packing method, destination port and delivery schedule.
