Re: [MW:26777] VALIDATION OF THE WELDING PROCESS FOR THE HARD FACING AND SEAT RING OF THE GATE VALVES

Dear Mr Neilesh Kumar

Thanks for the quick response. I shall use it and in case of any doubt I will seek your advice.

Thanks and regards

Hi ,

Its good to see your mail subject regarding validation , There is separate clause in API SPEC Q1 & API 5LD Section 7.5.2

Here are some information that you need to maintain separate format for Welding process validation.

A- DETAILS OF EQUIPMENT USED FOR VALIDATION
The process equipment's used for the validation shall be proven capable of performing the task for which they were designated

B- QUALIFICATION OF PERSONNEL INVOLVE IN THE VALIDATION
Welding Engineer / QC engineer shall ensure that only qualified personnel are assigned for the respective process, includes the weld overlay operator qualification

C- CRITERIA FOR REVIEW AND APPROVAL OF THE PROCESSS
Criteria for review and approval of the process shall be based on the criteria requirement specified in the appropriate qualification code and standard.

D-USE OF SPECIFIC METHOD AND PROCEDURES
WPS, PQR, Materials used, code requirements, specifications, procedures, inspection and testing, defining the acceotance criteria and its reference documents

E- REQUIREMENTS OF RECORDS
Equipment Operation Manual
Maintenance Records of Equipment
Calibration records for control pannel
Qualified WPS & PQR records
Operators Qualification records
Inspection & Testing records

Hope this clarifies your query and proceed further.

Dear Experts

I am required to submit to the client as to how the "VALIDATION OF THE WELDING PROCESS FOR
THE HARD FACING AND SEAT RING WELDING OF THE GATE VALVES" will be done. Following has already
Been complied and submitted but the client wants some more to be done:-

01.   WPS is accepted as submitted.
02.   PQR based on the WPS is in place and accepted.
03.   Heat treatment is not the requirement.

Please advise what else should be done, give the reference of such requirements.

Thanks in advance

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, ...
