Re: [MW:22967] Requirements Of PWHT for the Cross Country Pipe Lines

Re: [MW:22967] Requirements Of PWHT for the Cross Country Pipe Lines - Reg

Hi,

Since your WPS qu

Thanks & Regards,alified with PWHT, you can't use this for without PWHT jobs.

Since your construction code doesn't reqire PWHT you have 2 option.

01. Do new WPS/PQR without PWHT

02. If you don't want to prepare new, then follow as per your existing WPS (as your client said)

Refer scope of work, Isometric drawing and P & ID to find the applicable code.
Section 434.8.9 specifies about PWHT is ANSI B 31.4

Sir,
which design code is used whether ASME 31.4 or ASME 31.8.

Dear Experts,

We have done PQR with PWHT for the Material APL 5L Grade X60, and the coupon Size is 40 Inch & the Thickness is 38 mm with the Construction code application of API 1104 (Cross Country Pipe Line)

Based on the results we prepared WPS Also, But, As per API 1104 for 38.00 mm THK PWHT is not required

Now The Aramco PID instructed to follow the WPS to do all the Joints PWHT

What is the remdy for this & hat should we do

Kindly drop your advise

Thanks & Warm Regards,

Amul Raj T

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...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
