Petroleum and Natural Gas Industries - Steel Pipe for Pipelines - Technical Delivery Conditions - Part 1: Pipes of Requirement Class A - Second Edition
 N 3183-1

Annotation

This part of ISO 3183 specifies the technical delivery conditions for seamless and welded pipe of non-alloy and alloy (except stainless) steels with the basic quality and testing requirements (level A), which are intended for the transmission and distribution of combustible and non-combustible fluids (including water) in the petroleum and natural gas industries.

This part of ISO 3183 includes threaded and extra-strong threaded line pipe; and plain-end, regular-mass plain-end, special plain-end, extra-strong plain-end and double-extra-strong plain-end pipe; as well as bell and spigot pipe.

Dimensional requirements on threads and thread gauges, stipulations on gauging practice, gauge specifications and certification, as well as instruments and methods for inspection of threads are given in ISO 10422 and are applicable to products covered by this part of ISO 3183.

Grades covered by this part of ISO 3183 are L175, L210, L245, L290, L320, L360, L390, L415, L450, L485, L555, grades intermediate to the grades L290 and higher, listed in table 2.

For regular-mass and special plain-end pipe (special mass) as shown in tables 8 and 9 and for threaded pipe larger than nominal size 12 (see table 6) the size designations used herein are outside-diameter sizes. For all other pipe, the size designations are nominal pipe sizes. Where pipe size limits (or size ranges) are given, these are outside-diameter sizes except when it is stated that they are nominal. These outside- diameter size limits and ranges apply also to the corresponding nominal sizes (see 7.6).

NOTE 1 Attention is drawn to the definition for seamless pipe in 3.2.2.1.
