G.3.4.2 The test specimens, testing procedure, and rating of the specimens shall be in
accordance
(New) with API RP 5L3. The type of notch (pressed or chevron) shall be selected by agreement
between the manufacturer and the purchaser.
G.3.4.3 At least 80% of the heats shall exhibit a fracture appearance shear area of 75% or more
(New) for the specified test temperature.
G.3.4.4 In the event the average value of the two specimens from the length selected to represent
(New)
the lot is less than 75%, the manufacturer may elect to establish the lot average by testing
two specimens from each of two or more additional lengths of pipe in the lot. In
establishing the new lot average, the manufacturer may elect (a) to employ the combined
average of the three tests or more; or (b) to discard the result of the first test, reject the
pipe from which it was taken, and employ the combined average of the two or more
additional tests. Alternatively, the manufacturer may elect to test all the pipe in the lot, in
which case 80% or more of the lengths tested and applied to the order shall exhibit an
average of 75% or more shear.
G.3.4.5 Specimens showing material defects or defective preparation, whether observed before or
(New)
after breaking, may be discarded, and replacements shall be considered as original
specimens.
G.3.4.6 The manufacturer shall be responsible for replacement of such heats as may be
(New) necessary to meet the above requirements.
G.4 TEST FREQUENCY
G.4.1
G.4.2
This clause is cancelled.
Frequency of CVN and DWT for D
specification (Refer Table 18).
G.6 GUIDANCE FOR DETERMINING CVN ABSORBED ENERGY VALUES IN BURIED
ONSHORE GAS PIPELINES
G.6.1
This clause is also applicable for liquid or liquefied petroleum gas(LPG) pipelines.
G.12 ADDITIONAL FRACTURE TOUGHNESS REQUIREMENTS (TRANSVERSE CHARPY
V-NOTCH) FOR PSL2 PIPE.
G.12.1 Fracture toughness testing shall be performed in accordance with the requirements of
(New) para 10.2.4.3 and 10.2.1.2 of API Spec 5L and as modified in this specification, with a
test temperature of 32°F (0°C) or at a lower temperature as specified in the Purchase
Order. The required minimum all heat average full size absorbed energy value (based on
a set of three specimens) for transverse body specimen shall be the greater of (a) and
(b) given below.
The required minimum average full size absorbed energy value for weld and HAZ
specimen shall also be the greater of (a) and (b) given below. In addition, the lowest
individual absorbed energy value of the three specimens shall not be less than 80% of the
value specified.
