Fiberglass casing for downhole GRE programs
This fiberglass casing is downhole GRE casing manufactured by micro-controlled filament winding of epoxy resin and high-strength glass fiber roving. It is intended for operators who need corrosion resistance, long service life, light weight, and lower job costs versus conventional steel casing in suitable wells.
Production-range information already published for this line lists diameter DN100–DN250 and pressure grating 10 MPa–25 MPa, with design and production available according to customer demands. Referenced product standards include API 15HR Specification for High Pressure Fiberglass Line Pipe and SY/T 6267-2006 Specification for High Pressure Fiberglass Line Pipe. Typical uses called out here include casing-damage well repair, water-source wells, and CBM straight wells.
Note: Parameters on this page are general design information based on materials and technical status and are not an inspection basis by themselves. Products are not limited to the listed sizes and can be designed and manufactured to customer demands—always confirm final dimensions and ratings with CNPS.
