GB/T 19830-2017 Petroleum and natural gas industries—Steel pipes for use as casing or tubing for wells
Abstract
1.1 This standard specifies the technical delivery requirements for steel pipes (casing, tubing, and short sections), rough-machined fittings, fittings materials, and accessory materials, and establishes the requirements for three product specification grades (PSL-1, PSL-2, and PSL-3). The requirements for PSL-1 form the basis of this standard. Appendix H includes the standard technical requirements for PSL-2 and PSL-3 product specification grades for all steel grades except H40, L80 9Cr, and C110 steel grades.
The specifications, quality, wall thickness, steel grades, and applicable pipe end processing of the pipes covered by this standard are listed in Tables C.1 and C.2 or Tables E.1 and E.2.
Upon consultation between the purchaser and the manufacturer, this standard can also be applied to flat-end pipes of other specifications and wall thicknesses.
