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.
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:
Coating Type |
Typical Application |
Common Standards |
Buyer Check Point |
|---|---|---|---|
| 3PE / 3LPE coating | Buried oil, gas and water pipelines | DIN 30670, ISO 21809-1, CAN/CSA Z245.21 | Layer structure, coating thickness, cutback length and holiday test |
| FBE coating | External or internal anti-corrosion protection | AWWA C213, API RP 5L7 | Surface preparation, curing, adhesion and coating continuity |
| Liquid epoxy coating | Water, flow improvement and selected industrial service | Project specification, AWWA-related requirements | Dry film thickness, repair records and visual inspection |
| Cement mortar lining | Water transmission and utility pipelines | AWWA C205 | Lining thickness, curing condition and end protection |
| 3LPP / 3PP coating | Buried or submerged oil, gas and water pipelines where polypropylene coating is specified | ISO 21809-1, DIN 30678-1 or project specification | Design temperature, coating class and thickness, cutback, field-joint compatibility and inspection requirements |
| Hot-dip galvanized steel pipe | Above-ground utility, fire-service and exposed structural use where galvanized pipe is permitted | ASTM A53/A53M; ASTM A795/A795M for specified fire service; EN 10255 with EN 10240 where specified | Pipe and coating standards, zinc thickness or mass, ends and service approval; zinc coating alone does not establish pressure or potable-water approval |
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), witness points and shipment release criteria are agreed in the purchase order and inspection plan.
Use these technical resources to define the coating system, surface preparation, inspection records, handling controls and project-specific acceptance criteria.
