Performances of fiberglass reinforced composite plastic pipeline

Characterized by light weight, superior corrosion resistance, high pressure-bearing capacities, longer extension, flexibility, easiness in fabrication, energy conservation and higher safety factors, fiberglass reinforced composite plastic pipeline of high-performance flexible composite pipe with multi-layer structures will gradually replace steel pipe for development and transportation of hydrocarbons due to their overall low costs. Through a model, the mechanical property of fiberglass reinforced composite plastic pipe is analyzed. In addition, six types of fiberglass reinforced composite plastic pipes have been produced and explosion tested in accordance with different design requirements. Research results show that actual bursting pressures are basically the same with designed theoretical pressure with pressure extent of 5.5 to 25 MPa. These products can fulfill requirements presented by actual production process.
