Re: [MW:17248] Distance between two L-Seam

Dear Mr. Himanshu,

As per B 31.3 seam to seam minimum distance is given as 4 times thickness but B 31.3 haven't mentioned L seam to L seam staggering. Means can be weld without staggering.

Hello To ALL,

This clause applicable to Pressure Vessel, What about PIPING can any one suggest for piping as per (API 1104, B31.4, B31.3 or B31.1).

Thanks.

Hi Guru,

You can find in ASME VIII Div. I, UW-9 (d).

(d) Except when the longitudinal joints are radiographed
4 in. (100 mm) each side of each circumferential welded
intersection, vessels made up of two or more courses shall
have the centers of the welded longitudinal joints of adjacent
courses staggered or separated by a distance of at
least five times the thickness of the thicker plate.

Hope it is Ok for U...

Cheers,

Dear all,
I know that 100mm is permissble distance between two consecutive longitudinal seams but, can any one confirm minimum distance between two longitudinal seams should be mantained. Kindly mention ASME clause.

Thanks &Regards

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

Hi, You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this. Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime. Again, these simulated no. Of cycles shall be specified in MTC. The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case). One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example. In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
