Polyethylene Coating Test on Metal.

Our Services

Evaluation of coating thickness, adhesion, integrity, and protective performance of polyethylene coatings on metal pipelines and steel structures

Polyethylene coating test on metal is widely applied on steel pipes, tanks, and metal structures to protect against corrosion, moisture, soil chemicals, and environmental exposure. The Polyethylene Coating Test evaluates - Coating thickness Adhesion strength Holiday (pin-hole) detection Surface continuity Overall protective performance This test ensures that the coating meets required protection standards for long-term durability—especially for underground pipelines, water lines, oil & gas pipelines, structural steel, and industrial installations.

Why Polyethylene Coating Test Matters.

Ensures Effective Corrosion Protection on Metal Surfaces

Polyethylene coating acts as a barrier against: Soil corrosivity, Chemical attack, Moisture penetration, UV & environmental degradation. Testing verifies that the coating is applied correctly and provides maximum corrosion resistance.

Detects Coating Defects Before Pipeline or Structure Failure

Typical defects include: Pinhole/holidays, Porosity, Thin coating areas, Disbonded coating, Mechanical damage during transport or installation Testing prevents major failures such as leakage, rusting, and premature pipeline deterioration.

Confirms Compliance With International & Indian Standards

PE coatings must meet the specifications provided in: IS 10289 – External Fusion Bonded Epoxy/PE Coatings for Steel Pipes, IS 3589 / IS 4984 – Pipe Specifications, ISO 21809-1 – Coatings for Pipeline Transportation Systems, DIN 30670 – Polyethylene Coatings for Steel Pipes, Project or client QA/QC requirements, Testing ensures coating is consistent, durable, and approved for service.

Supports Long-Term Asset Life & Reduces Maintenance Cost

Proper coating ensures: Extended service life of metal pipelines, Reduced corrosion and maintenance frequency, Lower risk of costly shutdowns, Improved reliability of underground and submerged systems A well-tested coating system leads to safer and more economical infrastructure operations.
