Annex I

(normative)

Pipe ordered as “Through the Flowline” (TFL) pipe



I.1 Introduction

This annex specifies additional provisions that apply for pipe that is ordered as TFL pipe [see 7.2 c) 53)].



I.2 Additional information to be supplied by the purchaser

The purchaser order shall indicate which of the following provisions apply for the specific order item:

a)



type of length (see I.4);



b)



supply of jointers (see I.4).



I.3 Dimensions and grades

TFL pipe shall be SMLS or longitudinal seam pipe in the specified outside diameters, specified wall

thicknesses and grades given in Table I.1.



I.4 Lengths and jointers

Unless otherwise agreed, TFL pipe shall be furnished in double random lengths with no jointers.



I.5 Drift test

I.5.1

Each length of TFL pipe shall be tested throughout its entire length with a cylindrical drift mandrel

conforming to the dimensions given in Table I.2. During the drift test, the pipe shall be properly supported to

prevent sagging and shall be free of all foreign matter.

I.5.2

The leading edge of the drift mandrel shall be rounded to permit easy entry into the pipe. The drift

mandrel shall pass freely through the pipe with a reasonable exerted force appropriate for the mass of the drift

mandrel being used for the test.



I.6 Hydrostatic test

Each length of TFL pipe shall be hydrostatically tested in accordance with the requirements of 9.4, except that

the minimum test pressures shall be as given in Table I.1.

NOTE

The test pressures given in Table I.1 represent the lesser of 68,9 MPa (9 990 psi) and the pressures derived

using Equation (6), using a hoop stress, S, equal to 80 % of the specified minimum yield strength of the pipe.

Annex J

(normative)

PSL 2 pipe ordered for offshore service



J.1 Introduction

This annex specifies additional provisions that apply for PSL 2 pipe that is ordered for offshore service [see

7.2. c) 54)].

NOTE

This annex does not include requirements for specialized tests for pipe intended for applications such as pipe

reeling or for pipe that will experience high (> 0,5 %) total, single event strain during installation. For such applications,

additional testing can be necessary to prove the suitability of the pipe and the purchaser might need to supplement the

requirements of this International Standard with other appropriate provisions (e.g. see DNV-OS-F101 [14]).



J.2 Additional information to be supplied by the purchaser

i)



for Grade L555QO or X80QO and L555MO or X80MO pipe, a lower maximum tensile strength limit may

be agreed [see Table J.2, footnote b)];



j)



minimum average length other than 12,1 m (39.7 ft) and/or different range (see J.6.3);



k)



diameter and out-of-roundness tolerances for SMLS pipe with t > 25,0 mm (0.984 in) [see Table J.3,

footnote b)];



l)



use of inside diameter to determine diameter and out-of-roundness tolerances for non expanded pipe

with D W219,1 mm (8.625 in) [see Table J.3, footnote c)];



m) hardness test of the pipe body seam weld and HAZ of EW and SAW pipe (see Table J.7);

n)



CTOD testing (see J.8.2.2 and Table J.7);
