Re: [MW:16838] SS-304L Cladding on Inner Dia. of Carbon Steel ring

Dear,

Plz confirm,the Heat treatment of Cladded ring is necessary , my production engineer has recommended that we can use a local arrangement to cool the Ring at the time of cladding.

Cooling arrangement shall be - Water cooled by dipping the ring in the water tub.Heat is absorbed by cooling water.

Plz recommend is it possible.

Regards,

Vineet

Dear Experts,

I have to made SS-304L Cladding on Inner Dia. of Carbon Steel ring , below are the details:

Base Metal - SA 516 Gr.70

ID-490 mm , Thk-150 mm

Stainless Steel (304L)Cladding , thk- 5 mm finish

Plz furnish my queries-

1) Method / process of Cladding. You can use GTAW or FCAW as per your availabilty of Automatic ID overlay facilty

2) Filler Wire/Electrode--E309LT1 for barrier +E308LT1 for subsequent layer if FCAW and ER309L +ER308L for GTAW process

3) Heat treatment--For CS Pipe PWHT at Soaking tmp of 600-620C for 1hr soaking time which willbe suitable up to 20Hrs soaking time
Howevr you require to qualify PQR to decide the height at

undilted chemistry of 308L is achieved from base of overlay

Regards,

Vineet Kumar

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...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
