Oil and gas industries including lower carbon energy — Thermoplastics lined tubing for wells

Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone — Tubes à revêtement thermoplastique pour les puits

Abstract / scope

This document specifies requirements for downhole thermoplastics lined tubing (TLT) used in the oil and gas industries, including configuration, materials, manufacturing, inspection and testing, documentation, marking, packaging, transportation, storage and use.

This document is applicable to downhole thermoplastics lined tubing (TLT) used in contact with media related to oil and gas exploration and production (which involves multiphase flow, as well as water injection).

This document is suitable for thermoplastics including but not limited to polyethylene (PE), polyethylene of raised temperature resistance (PE-RT), ultra-high molecular weight polyethylene (PE-UHMW), crosslinked polyethylene (PE-X), polypropylene (PP), unplasticized polyamide (PA-U), polyketone (PK), polyphenylene sulfide (PPS), polyvinylidene fluoride (PVDF), and polyetheretherketone (PEEK) which meet the requirements of relevant design specifications, standards or regulations.
