Hi every body
Can every body advice me that, what is different between material A537 CL 1 and A537 CL 2?
The above materials is used for LPG service (in spherical tank ) with the design condition is:
Temp. Operation/Design: 28/-10deg.C
Wall Thickness : 57 mm
Hope to see your advice soon
Dear All,
My Question is : If a welder has done performance qualification for SMAW using E-7018, would also qualified for E8018 ?
Note : other variables are unchanged
Dear Guys,
I am building a new spherical thank Material is SA537-Class1, wall thickness= 31 mmm.
According to ASME sec VIII div 2. PWHT not mandatory , but user want to perform PWHT.
Fabricator of plate said :
ASME-SA-537 ( 65mm and under),Code Requirements: Tensile Strength :485 – 620 MPA...

Hi Guys,
I want to know about reference of requirement of RT ( radiography test), we have to perform before or after PWHT?.
Material is SA 537 Class 1., thickness = 31 mm (PWHT is user requirement)
Applicable Code is ASME sec.VIII Div. II.
Thanks in advance
Hello, I have a Question :
After we perform PWHT (stress relieve annealing),is there any decrease of tensile strenght of material, if yes ,how many percent decrease? Thanks
Note :
Material : ASTM A-537 class 1, stress relieve temperature @ 595º (ref ASME –III div. 2) :Equipment : Spheical...
