RE: [MW:22159] WPS for Support

One major problem is that you do not tell us the governing Code.

If you are welding on pressure boundary that is governed by an ASME Code(s), then the you may not perform any weld to pressure boundary if it is not properly qualified in accordance with ASME Section IX. As an example, I include, in part, ASME Section I, PW-28:

PW-28 WELDING QUALIFICATION AND WELD

RECORDS

PW-28.1 Requirements for Qualification of Welding

Procedures, Welders, and Welding Operators.

PW-28.1.1 The Welding Procedure Specifications,

the welders, and the welding operators used in welding

pressure parts and in joining load‐carrying nonpressure

parts, such as all permanent or temporary clips and lugs,

to pressure parts shall be qualified in accordance with Section

IX.

PW-28.1.2 Except as provided in (a) and (b), the

Welding Procedure Specification, the welders and the

welding operators used in welding nonpressure‐bearing

attachments which have essentially no load‐carrying function

(such as extended heat transfer surfaces, insulation

support pins, etc.) to pressure parts shall be qualified in

accordance with Section IX.

Clearly your pipe shoe is load bearing and therefore requires that the welding be performed in accordance with a qualified welding procedure by a properly qualified weldor.

Dear ALL,

Please comment on the issue, Pipe to Shoe support fillet welding - Have WPS for SMAW process, can a welder do pipe to shoe support fillet welding in GTAW process.

Please note that for this specific project we don't have a wps qualified for GTAW process, only qualified wps for SMAW process.

Awaiting replies !

Regards

Richard

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

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

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, ...
