High Performance Powder Coating

High Performance Powder Coating (HPPC) is an advanced powder-based system that represents the latest development in anti-corrosion systems. This coating system consists of a fusion bonded epoxy layer, a polyolefin adhesive layer and a tough powder based polyethylene top coat. HPPC is designed to protect buried oil and gas pipelines in environments where excellent mechanical protection, moisture and corrosion resistance are required. The innovative HPPC coating process allows for a substantially better weld seam coverage than for other typical extruded polyolefin based systems, further ensuring the integrity of your assets.

Features & Benefits

Powder Based System Enhances Overall Asset Integrity

  • The powder based system lowers shielding, ensuring long term asset integrity through increased compliance with Cathodic Protection systems.
  • The FBE component of HPPC provides excellent adhesion to steel, providing excellent long term corrosion resistance and protection of pipelines operating up to 85°C.

Fused Monolithic Coating System

  • The unique application process of HPPC results in a fused, monolithic profile that prevents delamination and loss of adhesion.
  • The system demonstrates excellent field handling and flexibility characteristics, minimizing construction installation costs.

Very Good Mechanical Protection

  • HPPC provides excellent uniform coverage of the weld bead profile, preventing “tenting” and weaknesses in the coating cross-section.
  • Polyethylene component protects the pipeline during transportation, reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.
