Specialized fusion‑bonded epoxy (FBE) internal coating for sweet gas pipelines, engineered to dramatically reduce surface roughness, improve flow capacity, and lower transportation costs.
Peka‑Pro FE from Peka Chemie is a premium internal FBE coating, purpose‑designed for pipelines transporting sweet (non‑corrosive) natural gas. Its advanced formulation produces an ultra‑smooth bore surface, cutting the internal surface roughness (Rz) from typical 30–50 μm to as low as < 1 μm.
This reduction minimizes turbulent drag, thereby improving gas transmission efficiency, enhancing throughput, and reducing compressor energy demand over the pipeline’s service life. Peka‑Pro FE is mechanically robust, chemically stable, and resistant to blistering under pressure, making it ideal for long‑haul gas infrastructure.
