API 15HR GRE Tubing

GRE means glass-reinforced epoxy. For a GRE tubing inquiry, identify the intended service and request the specification and supporting documents for the exact size and connection offered.

What API 15HR means

API 15HR is the specification titled High Pressure Fiberglass Line Pipe. It is a standard designation, not a 15-hour design life. The required service life and its design basis must be stated separately.

For downhole water injection, reinjection or polymer injection, specify the well conditions and the required tubing standard. Do not infer downhole suitability from a line-pipe standard number alone. Ask IFGS to identify the applicable specification, edition and test documentation for the proposed product.

Information needed for selection

• Well depth, completion arrangement and required tubing size.
• Fluid composition, normal and maximum temperature, operating pressure and design pressure.
• Required connection, thread drawing, installed length and mechanical loading requirements.
• Inspection requirements, requested service life and documentation needed for project approval.

The catalogue diameter and pressure ranges in the Specifications tab are reference ranges. Request the size-specific pressure-temperature rating and connection limits; a range does not establish that every size is suitable at its upper pressure value.
