Field Joint Coating

Field Joint Coating (FJC) is a vital solution for protecting cutback areas and girth-welded joints during pipeline construction on-site (onshore and offshore). Central Steel offers complete field joint coating materials and technical support to ensure joint protection matches the factory-applied pipe coating quality.

Field Joint Coating Systems Available:

Polyethylene / Polypropylene Heat Shrinkable Sleeves (HSS): Radiation cross-linked polyolefin sleeves lined with hot-melt adhesive for 3LPE/3PP pipeline joints.

Field-Applied Fusion Bonded Epoxy (FBE): Induction heating and powder induction spray for continuous FBE coating consistency.

Liquid Epoxy / Polyurethane Coatings: Two-component liquid systems for field manual or automatic spray applications.

Specifications & Suitability:

Applicable Pipe Diameter: Φ60.3 mm – Φ2220 mm (2" – 88")

Applicable Pipe Wall Thickness: 4.0 mm – 50.0 mm

Operating Temperature Range: -40°C to +120°C (depending on sleeve and epoxy grade)

Compliance Standards: ISO 21809-3, EN 12068, DNV-RP-F102.

Applications

Field joint coating is used in:

Onshore oil and gas pipelines
Offshore and subsea pipeline installation
Buried transmission pipelines
Water pipelines and other infrastructure projects
Coating repairs and exposed steel areas requiring reinstatement
