1 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.
