Re: [MW:10502] WPS

By Materials & Welding
Hi,
For Quiery No.1 : you can use as per QW100.3.Please find below the extraction.
QW-100.3 Welding Procedure Specifications (WPS)
written and qualified in accordance with the rules of this
Section, and welders and welding operators of automatic
and machine welding equipment also qualified in accordance
with these rules may be used in any construction
built to the requirements of the ASME Boiler and Pressure
Vessel Code or the ASME B31 Code for Pressure Piping.
However, other Sections of the Code state the conditions
under which Section IX requirements are mandatory, in
whole or in part, and give additional requirements. The
reader is advised to take these provisions into consideration
when using this Section.

Welding Procedure Specifications, Procedure Qualification
Records, and Welder/Welding Operator Performance
Qualification made in accordance with the requirements
of the 1962 Edition or any later Edition of Section IX may
be used in any construction built to the ASME Boiler and
Pressure Vessel Code or the ASME B31 Code for Pressure
Piping.
Welding Procedure Specifications, Procedure Qualification
Records, and Welder/Welding Operator Performance
Qualification made in accordance with the requirements
of the Editions of Section IX prior to 1962, in which all
of the requirements of the 1962 Edition or later Editions
are met, may also be used.
Welding Procedure Specifications and Welder/Welding
Operator Performance Qualification records meeting the
above requirements do not need to be amended to include
any variables required by later Editions and Addenda.
Qualification of new Welding Procedure Specifications
or Welders/Welding Operators and requalification of
existing Welding Procedure Specifications or Welders/
Welding Operators shall be in accordance with the current
Edition (see Foreword) and Addenda of Section IX.

Quirey No.2:
Yes.You can use,Because both are same group number(Group no.1 - S355JR-Gr.No.1.2
S275JR - Gr.No.1.1 acc.to ISO20172)
As per ISO15614,Table - 3 ,WPS qualified with Gr.No.1-1 can qualified for 1-1 with restrict to Note - a as specified below.

Table 3 — Range of qualification for steel groups and sub-groups
Material (sub-)   Range of qualification
group of test      1  – 1 (Note-a)
piece
1 - 1

Note (a) : Covers the equal or lower specified yield strength steels of the same group


Thanks & Regards,

Dear members,

I have one query regarding WPS.

1) One of my client made a comment on a WPS which i had submitted to
them for approvel that  Procedures are from 2001.  My question is Is
there any time limit for WPS?  In my knowledge answer is No, a
qulified procedure can be used any time without changing the essential
variable.

2) I have one  qualified wps with base metal S 355 JR to S 275 JR.
Can I use this WPS to weld  S 355 JR to S 355 JR and S 275 JR to S 275
JR?

Please clear my doubts, if possible with code reference.

Thanks & Regards.

Manoj

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
