RE: [MW:13023] which is better BW OR BE?

By Materials & Welding
 
 
You are talking about 2 different things.  BE is not the same as BW.  Please let me explain:
 
You should specify BE if you are referring to a specific pipe end or fitting. 
 
BE=bevelled end.  PE=plain end.  TE=threaded end. 
 
If you order an NPS 1 nipple PE/BE, you will receive a nipple that is bevelled one end and the other end is plain. 
 
If drafting an Isometric for example, if you are referring to a joint, then use BW (Butt-weld), SW (Socket-weld), but on the material list, the items will be called out as to their end preparation (BE, PE, TE).
 
Be aware that end preparation differs for Socket-welded joints compared with Butt-welded joints, check your line requirements as per your Engineering department/Customer Specifications. 
 
Warm regards,

 both are same

hi friends,
I need your expert opinion,
which is better for fittings e.g Elbows,Tee reducer  END TYPE=BW(butt
weld) or BE(bevel end).i am working on smart software and dealing with
item coding.some people write BE AND some BW as End Type.which is
better to be used ?are these same or different?thanks in advance .

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

By Materials & Welding
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

By Materials & Welding
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...
