Dear Sirs,
Thanks for your reply.
The actual Batch test certificate of E310-15 electrode is having an chemical composition of Carbon-0.092, Chromium-25.055 & Nickel 20.870.
As per QW404.5 (b) and comparing the chemical composition values of batch test certificate and QW 442 A No. 8 & A No. 9...

I have to weld the material grade SS 310 to SS 310 and for which electrode selected is E310-15.
Query
As per material chemical composition of SS 310, Maximum percentages of elements are as follows
Carbon - 0.25, Chromium - 14.5-30.0, Nickel - 19.0...
Thanks for all replies.

Sir, As per ASME B31.1 Table 132 the temperatures and time not mentioned as minimum. But for alloy steel pipes I think its better to go with 2hours soak time. Please let me know if you have any comments.
Thanks again
In one of the Project Alloy steel Piping, most of the Piping Spools are in accordance with ASME B31.3 and only one Spool they need as per ASME B31.1. Now The concern is PWHT as per ASME B31.3 for P4 (A335 P11), P5A (A335 P22) Heat treatment soaking time is Minimum 2hours, wheares as per ASME...

Dear Sir,
1. We have used qualified welder as per ASME Sec.IX
2. Yes we performed 100%MPT on the Grounded off area.
3. Performing destructive examination means whether we have to do any destructive tests on flange, which test?, as we are planning to perform Hardness test on the...
We are Fabricating Pipe Spools, inorder to identify the Pipe Spools we are cold hard stamping a two digit identification mark on flange face (Thickness Portion) without disturbing/interfering manufacturer's identification.
We had some error in hard stamping of Spool identification, to correct...
Hi,
@denlow60
Most of the electrode manufacturer's recommend us to use E9018-B3 to weld SA335 Gr.P22 Pipe Material.
I have a question on your reply, Is it electrode E8018-B3 or B3L, Because as per ASME Sec.II Part-C E8018-B3 doesn't exist only E8018-B3L is mentioned.
Thanks everyone for your...
Hi,
Good Day!!!!
I have to weld SA335 Gr.P22 to P22 Material to weld this whether I can choose the below mentioned electrode and filler wire-
GTAW - ER80S-B3L
SMAW - E8018-B3L
In most of the welding hand books and manufacturer recommendation electrode E9018-B3 & ER90S-B3 is selected to weld...
Hi,
Good Day!!!!
Design Code - ASME B31.3

We have a WNRF Flange of Dia 20" of which the serration face is damaged (Approximately 3mm Depth and Length 60mm) due to the improper handling.
Can any one recommend me the correct procedure to rectify the damage...
Good Day!!!!
Thanks Sir for your reply.
Most of the MTCs we have reviewed it mentions only the Starting material (Pipe, Bar or Plate), it doesn't mention the condition of Raw Material used to manufacture the fittings as it is not an requirement to mention in the MTC as per SA234 Cl.17.0...
Good Day Everyone!!!!
Material Description - SA234 Gr.WPB, Hot formed between 780-980 Degree Celcius
In MTC it has been mentioned as the Tensile test (Mechanical Properties) carried out on Raw Material.
As per SA 234 Tensile requirements Cl.9.0 (9.1 to 9.4), I am bit confused and would like to...
Good Day Everyone......

Hi,
No because, If Impact test requirement is specified then Group No. becomes essential variable from supplementary essential variable and P No. is also an essential variable. Hence, a qualification of procedure is required.
Hi,
I have two questions regarding Weldolet which are mentioned below-
1. I have a Weldolet of size designation/marking as 36"-2" x 3/4" 3000# - which means we can use this Weldolet for Run pipe sizes ranging from Dia 2" to 36" with an outlet size of 3/4". This particular Weldolet is not...
