1.Scope:

2

The Stress analysis is carried out for the main steam line from Boiler PR-0191 up to the branch point in the existing steam header.

The isometrics of following lines have been considered for the analysis.

300-STHH-483040 Main steam line from Boiler PR 0191

100-STHH-483042 Line from main steam to deaeration( up tocontrol valve PV 483275)

100-STHH-483044 Bypass of PV-483275

250-STMH-483059 Down stream of control valve PV-483275

150-STMH-483117 Down stream of control valve PV-483275

100-STHH-483126 Line from main steam line to PV 483324 Silencer

250-STHH-483041 Line from main steam line to PV 483273 Silencer

2.Design Basis

2.1 The input file is based on the Piping Isometrics2.2 The pressure, temperature and material are from Piping Isometrics2.3 The pipe stress analysis is according to ASME B31.12.4 The software of stress analysis is CAESAR II Version 5.0

3.Load Cases considered

CASE 1 (HYD) WW+HP+HHydro

CASE 2 (OPE) W+D1+T1+P1+HThe whole system is at 515°C except The down stream of PV483273&UV483324 at ambient The down stream of control valve PV483275 at 336°C

CASE 3 (OPE) W+D2+T2+P1+HThe main steam line from boiler to the Battery limit XV is at 515°C The down stream of XV is at ambient.The down stream of UV483324 is at ambientThe down stream of PV483275 is at 336°C

CASE 4 (OPE) W+D3+T3+P1+H The main steam line from boiler to the battery limit XV is at 515°C

The down stream of XV is at ambient.The down stream of PV483275 is at 336°C

CASE 5 (OPE) W+P1+HSustained

CASE 9 (SUS) WNC+HWeight with no contents+Hanger

CASE 13 (EXP)L13 =L2-L5Expansion from installation to temperature T1

CASE 14 (EXP) L14=L3-L5Expansion from installation to temperature T2

CASE 15 (EXP) L15=L4-L5Expansion from installation to temperature T3

CASE 19 (SUS) L19=L2-L6Hot sustained corresponding to Temp T1

CASE 20 (SUS) L19=L3-L7Hot sustained corresponding to Temp T2

CASE 21(SUS) L19=L4-L8Hot sustained corresponding to Temp T3

Where P1=Design pressureHP=Hydro test pressureVectors D1,D2 and D3 are identical and corresponds to the Movements of Nozzle node 10
