1. Scope
1.1 General
This Standard covers seamless electric-welded pipe (flash-welded pipe and low-frequency electric-welded pipe excluded), and submerged-arc-welded pipe primarily intended for use in oil or gas pipeline systems.
Notes:
(1) Flash-welded pipe is pipe manufactured by a process using electric-resistance heating to produce a simultaneous coalescence over the entire area of the abutting edges and the application of pressure for joining.
(2) Low frequency is less than 1 kHz.
1.2 Size, Grade, and Category
Note: It is not intended that pipe be available in all combinations of size, grade, category, and manufacturing process.
The individual pipe manufacturers should be consulted to ascertain the availability of specific pipe items.
1.2.1 Outside Diameter and Wall Thickness
This Standard covers pipe having specified outside diameters from 21.3 mm to 2032 mm inclusive. The standard outside diameters and wall thicknesses are given in Table 1.
1.2.2 Grade
For other than sour service, this Standard covers pipe from Grade 241 to Grade 690 inclusive. For sour service, this Standard covers pipe from Grade 241 to Grade 483 inclusive.
Note: The standard grades are Grades 241, 290, 359, 386, 414, 448, 483, 550, 620, and 690; however, intermediate grades are also permitted.
1.2.3 Category
This Standard covers pipe in the following categories:
(a) Category I ? pipe without requirements for proven pipe body notch-toughness properties;
(b) Category II ? pipe with requirements for proven pipe body notch-toughness properties in the form of energy absorption and fracture appearance; and
(c) Category III ? pipe with requirements for proven pipe body notch-toughness properties in the form of energy absorption.
