Description

A protective fiber glass coating (hereinafter referred to as PFC) for steel pipes and bends with an outer diameter of 219 to 1420 mm, designed to protect the pipelines corrosion-resistant coating from mechanical damage during construction, reconstruction, repair and during operation. By designation, PFC is applied to the pipe in two versions: general “G” or reinforced “R”.
