Re: Re: [MW:9893] Groove design and bevel

DEAR SIR GROOVE DESIGN IS NOT AN ESSENTIAL VARIABLE, BUT YOU SHOULD FOLLOW ASME B 31.3.

Dear Manpreet,
>>I would like to share my experience realted to same issue which is raised by Mr. Husain.
>>In our previous project we received fittings thickness greater than 22 mm with compound bevel .However pipes received with single bevel.Then contractor propose to do compound bevel for pipes with additional work and of course with extra cost.
>>Construction code ASME 31.3 & approved WPS was without Impact, with PWHT as per ASME IX .
>>WPS/PQR was qualified by Ludwing (one of reputed TPI ) showing various combination of joint configurations.Based on that we told contractor to go ahead with welding as it is - i.e.one side compound bevel & other side single bevel
>>So there was big noise between contractor & us....contractor was not ready to weld joint like that
>>Please let me know then my interpretation was correct or not ?
>>Warm regards

Dear All,

I have a query, kindly share your valuable knowledge on this subject.

1-As per ASME IX, Table QW-253 and QW-256, groove design is non-essential variable for SMAW and GTAW welding.
2-As per ASME B31.3, Fig 328.4.2 and ASME B16.25 Fig 3 and 5 (also Para 3.1C), components having thickness above 22 mm shall have compound bevel.

I would like to know that if the requirements of ASME B31.3 and 16.25 as stated above are mandatory? Because as per SEC IX, it is non-essential variable.
What I have observed at site, all pipes and fitting above 22 mm thickness have compound bevel from manufacturer, but all bevel prepared at side are single bevel. Is this acceptable?
