[MW:31036] Re: ASME672 ELECTRIC-FUSION-WELDED STEEL PIPE FOR HIGH-PRESSURE SERVICE

By Materials & Welding
SAW is one of  the EFW (electro fusion welding) process and is acceptable
double welding is welding from both sides

Hello Peers, 
the above specifications states EFW welding whereas the supplier offers SAW pipes could you please advise this is acceptable or not.
The codes states:
Quote:
5.2 Welding:
5.2.1 The joints shall be double-welded, full-penetration
welds made in accordance with procedures and by welders or
welding operators qualified in accordance with the ASME
Boiler and Pressure Vessel Code, Section IX.
5.2.2 The welds shall be made either manually or automatically
by an electric process involving the deposition of filler
metal.
:Unquote

what is intended by "Double-Welded" in 5.2.1
Regards,

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...
