WPS and PQR

[saleem manhappulath]

Dear all

I have PQR Cs to inconel with impact. 

Thinkness 11.07mm

Deposit weld metal thickness: gtaw-6mm smaw -5.07

I need prepare wps for gtaw only

What thickness range will mention for base metal in wps

Regards 

Saleem

Dear Saleem

Basemetal /weld metal Thickness qualified range depends on the factors like construction code(design code, service) ,welding code , client specifications and other international standards applicable for an application.

if code of construction ASME SEC VIII DIV.1 & welding code ASME SEC IX 

Weld deposit thickness range  : 12mm Max

base metal Thickness range: 11.07mm to 22.14mm Max

if code of construction  ASME B31.3 & welding code ASME SEC IX

Weld deposit thickness range  : 12mm Max

base metal Thickness range: 5.53 mm to 16.07mm Max

Thanks& Regards, 

Srinivas Rao

Dear All,

As per B31.3 - 2020 & ASME SEC IX 

Base Metal Thk Range 11.07 mm to 22.14 mm

Weld Metal Thk (Max)    12 mm

Regards,

Manikandan

Dear  Manikandan  , 

 Impact testing qualification limites for ASME B31.3 2020 for highpressure piping it is still T/2  to T+6  , however it shall be clarified by ASME body  refer attached. 

and construction code always supersedes welding code.

Regard,

srinivas Rao

 

[Manikandan J]

Dear Mr.Srinivas,

  T/2  to T+6 thickness limits not applicable as per latest  latest edition of B31.3 2020 & It shall be applicable for 31.3-2018 Edition

Please find the snapshot of  both 2018 & 2020 Edition for your reference.

Regards,

Manikandan

Dear Mr. Manikandan,

still T/2  to T+6 thickness limits is applicable for  chapter IX piping attached file for your infroamtion and  How ASME Is applied strigent requiremnt to normal pressure piping (chapter -V)  , why more relaxtation on hIgh pressure piping (chapter IX)  is a question now , let ASME B31.3 2020 Edition intepreations can only clarify this requirment. let us wait till that time.

Thanks & regards,

Srinivas Rao

What I understand is :

When we are in high pressure we use T/2 to T+6

When we are in normal pressure we use T/2 to 2T 

Is that right ??
