2.0 DESIGN AND CONSTRUCTION

2.1 The pressure temperature ratings for tee, weldolets, elbows and flanges shall be calculated respectively in

accordance with ANSI B31.8, DIN2413 and ANSI B16.5. For all other types of fittings (caps, reducers,

nipple) ASME section VIII shall apply.

The standard dimension shall be in accordance

� Flanges such as weld neck flanges and blind flanges shall conform to the requirements as follows :

- ASME B16.5 upto sizes DN 600 mm (24") excluding DN 550 mm (22"),

- MSS-SP-44 for sizes DN 550 mm (22").

� With ANSI B16.9 for the tees, reducers and elbows (except for short radius elbows which should be in

accordance with ANSI B16.28)

� With ANSI B 16.9 for the caps,

� With ANSI B 36.10 for the nipples,

� And with ANSI B16.5 / MSS SP 44 for the flanges.

2.2 The temperature range as follows:

• For above ground Services (CS) : -20°C to +65°C

• For above ground Services (LTCS) : -45°C to +65°C

• For Underground Services : -20°C to +60°C

The Design pressure is 98 barg.

2.3 The wall thickness shall meet the following requirements:

2.3.1 The maximum allowable stress in the base material and in the weld shall be equal to fifty per cent (50%) of

the minimum yield strength guaranteed by the specification of the steel used.

2.3.2 The minimum wall thickness must be greater than the following:

a. Thickness calculated in line with requirements given in ASME B 16.9 Para 2.2

b. Nominal Thickness of pipe

Thickness calculation is to be submitted to Owner/Owner’s Representative for prior approval before

manufacturing.

2.3.3 If the fitting has yield strength lower than the yield strength of the pipe to which it is intended to be

welded, the wall thickness in each zone of the fitting is at least equal to the largest value "tr" of either.

� The specified pipe wall thickness times the ratio of the minimum yield strength guaranteed by the

standard of the steel of the pipe and the minimum yield strength guaranteed by the standard of the steel

of the fitting;

� The absolute minimum thickness required by the applicable code(s).

2.3.4 The specified pipe wall thickness and grade (with reference to the equivalent grade in ASTM spec. or API

5L spec.) with which the fitting and flange is intended to be used is specified in the piping material

specification.

Fittings such as tees, elbows, reducers, etc. shall be either welded or seamless type. All welded fittings

shall be subjected to heat treatment. All fittings (except weldolets) shall comply with

Page 34 of 78


D 11077

117


2.3.5 The thickness at the welding end shall not exceed 1.5 times the nominal wall thickness of the pipe to be

matched.

2.3.6 All the above requirements also apply to the welding ends of the flanges.

2.4 The manufacturer shall submit for approval to the Pipe Laying contractor and to the Client the dimensional

drawings, calculations, and the material part lists for all the types of fittings and flanges. All the documents

must be identified with the Client's order number.

2.5 The design shall take into consideration performance requirements prescribed in paragraph 2.6.

2.6 The design of tees, reducers or elbows must be established, by proof testing, in accordance with par. 2.7.

The design of the other fittings must be established by mathematical analysis according to ASME code.

2.7 All fittings under this specification shall be designed to withstand a field hydrostatic test pressure with non

corrosive water, after installation, during 24 hours at a following pressure level:

Minimum: P = 1.5 MOP

Where:

P = hydrostatic test pressure, bar

MOP = maximum operating pressure = 91barg.

The pressure level will however not exceed 1.9 MOP for the fittings and 1.5 times the 38°C pressure

rating for the flanges.

2.8 Design Proof Test

This applies to fitting only and not to flanges.

2.8.1 In addition to the requirements of par. 2.3.1 to 2.3.4 proof tests shall be made as evidence of the adequacy

to the design references. Records of design or successful proof tests shall be available at the facility for

inspection by the Client and copy shall be added to the Certified Material Test Report (CMTR, par. 6.3.).

2.8.2 Unless otherwise agreed upon between manufacturer and Client, the only required proof test is a bursting

strength test.

2.8.2.1 Prototype fittings, representatives of production, selected for test shall be identified as to material, grade,

and lot, including heat treatment. They shall be inspected for dimensional compliance to this standard.

2.8.2.2 Straight seamless or welded pipe sections, whose calculated bursting strength is at least as great as that

calculated for the fittings, shall be welded to each end of the fitting to be tested. Any internal misalignment

greater than 0.06 inch (1.6 mm) shall be reduced by taper boring at a slope not over 1:3. Length of pipe

sections for closures shall be at least twice the pipe O.D. Shorter lengths may be used as follows:

� The assembly must withstand at least 110 % of the pressure computed in 2.7.2.3.

� Minimum length of pipe shall be one pipe O.D. for sizes NPS 8" and smaller.

Test fluid shall be water or other liquid used for hydrostatic testing.

2.8.2.3 Hydrostatic pressure shall be applied until the fitting ruptures. The actual test

pressure prior to rupture must at least be equal to the adjusted proof test pressure

defined as follows:

P (adj.) = P x S act

s

( .)

where

P (adj.) = the adjusted proof test pressure, bar

P = the computed proof test pressure at burst of any part of the assembly, bar

S = minimum specified tensile strength of the pipe for which the fitting is intended to be

used, N/mm2

Page 35 of 78


D 11077

117


S (act.) = the actual tensile strength of the material of the test fitting (determined on specimen

representative of the test fitting), N/mm2

The computed proof test pressure shall be determined as follows:

which refers to the pipe which the fitting's marking identifies and, where

P = 20S t

D

. where,

P = Computed bursting pressure of the pipe, bar

S = Minimum specified tensile strength of the pipe, N/mm2

t = Nominal pipe wall thickness, mm

D = Specified outside diameter of pipe, mm

2.8.2.4 As an alternate, if the pipe ruptures, or if sufficient pressure to rupture any part of the assembly cannot be

attained, the test pressure is acceptable if a final test pressure is at least 105 % of the adjusted proof test

pressure.

2.8.3 A successful proof test on a prototype fitting, selected as required in subsection 2.7.2.1., may be used to

qualify other fittings to the extent described herein.

2.8.3.1 One test fitting may be used to qualify similar designs which shall not be smaller than one-half nor larger

than two times the size of the test fitting.

2.8.3.2 The test on a non-reducing fitting qualifies reducing fittings of the same pattern.

2.8.3.3 The untested fitting must have a t/D ratio neither less than one-half nor more than three times the t/D of the

test fitting.

2.8.3.4 The pressure retaining capacity of a fitting, made of various grades of steel, will be essentially directly

proportional to the tensile properties of the various grades. Hence, it is necessary to test a prototype in only

a single grade to prove the geometric design of the fitting.

2.8.3.5 A test on a prototype elbow qualifies elbows having longer radii than the test fitting providing they qualify

under 2.7.3.1 and 2.7.3.3.

2.8.3.6 A change in design from seamless fitting to fitting containing (a) seam weld(s) require(s) an appropriate

prototype test. A change of location of the seam weld requires a separate prototype test. Any deviation

must be submitted for approval to the pipe laying contractor.

2.8.4 If the manufacturer cannot give the certificate of prototype bursting test, the design of fittings shall be

verified as follows. A prototype must withstand during 24 hours 1.4 times the maximum operating

pressure (M.O.P). The prototype is considered to be agreed upon if the deformations measured during the

test at 1.4 X M.O.P. shows that the stress does not exceed 70 % of the minimum guaranteed yield strength

of the fitting.

The certificate of this prototype qualifies in the same limits than par. 2.7.3.

2.9 Fitting dimensions

One of the principles of this standard is the maintenance of a fixed position for the welding ends with

reference to the centreline of the fittings or the overall dimensions, as the case may be.

Dimensional standards will be in accordance with §2.1.

2.10 Fitting and Flanges Tolerances

2.10.1 Tolerances for welding ends, out-of-roundness at the welding ends and inside diameter at the bevel are

shown hereafter. Other tolerances wall thickness are as per corresponding codes: ANSI B16.9 standard

and for short radius elbows ANSI B16.28 standard.

thickness unequal to the pipe with which it is intended to be used, the welding end preparation at the joint

has to conform with Figure 3.

2.10.3 Out-of-roundness at the welding ends

The out-of-roundness, defined as the difference between the maximum and the minimum inside diameter at

the welding ends shall not exceed 1 % of the specified inside diameter for sizes NPS 4 and smaller.

Fittings & flanges NPS 4 and larger shall be machined true round.

4.3 Normalising Heat Treatment

Start & stop temperature chart shall be signed by TPIA, also power failure log shall be maintained.

4.3.1 After forming and welding, all fittings & flanges shall be heat treated by normalising. Normalising shall be

carried out in such a way that the base material acquires a fine grained perlitic structure. If the

manufacturer can give proof by qualified manufacturing procedure that after forming, the steel of the

fitting & flanges has a homogeneous fine grained perlitic structure, he can ask for a derogation supported

by technical file to the Client and to the pipe laying contractor.

The normalizing procedure requires the approval of the pipe laying contractor. Good care shall be taken to

avoid direct contact of the flames with the material to be heated.

During the normalizing period, the temperature of the heat treatment lot shall be automatically recorded by

a sufficient number of thermocouples attached to the material surface. The thermocouples shall be

adequately protected against the influence of heat radiation. Temperature variations shall be within ±

20°C. The manufacturer shall furnish time temperature charts of each heat treatment lot. The fittings &

flanges belonging to each treatment lot shall be specified on the charts. Temperature measurements by

other means are permitted only if approved by the pipe laying contractor.
