Welding Materials

(OP)
Hi;
I would like to know if there any limitations if welding piping ASTM A106 Gr B with piping ASTM A333 Gr 65.
Regards

RE: Welding Materials

These two materials may be used in the difference process conditions.
Why to mix them together? And, what the limitation is based on?

RE: Welding Materials

(OP)
Hi,
For some reasons we are obliged to use them togather in the same process condition for a max design temperature of 290°C

RE: Welding Materials

(OP)
Dear all
What is the difference between the next materials:
ASTM 357 cl 1 and ASTM 516 Gr 70.
Can they be used in the same process conditions?
can they be interchangeable?.
which one is better for gas hydration vessels.
Regards

1. Please make a new topic for a new questions
2. As to your other questions, there's no 'better'. The may be (grossly) the same, but different for a reason. As such, it depends on the process conditions, which you havent specified. They're not interchangeable per se, but may be, for certain conditions.
3. Your questions seem very basic. Whats your level of expertise and experience?

RE: Welding Materials

Dear XL83NL,

Guess he is a trainee doing some project.

This is such a wonderful forum, but some freshers with little or no experience and expertise use it for selfish gains.

Regards.

RE: Welding Materials

There is no problem welding A-106 to A333 65. You need to obtain the specifications of A-516 and A357 CL1 and compare.

RE: Welding Materials

Could someone enlighten me as to what A333 65 is?

RE: Welding Materials

Grade 65 is, indeed, not an A333 listed material

RE: Welding Materials

I apologize for thinking the questioner new what he was talking about nd did not check. Possibly he meant Gr 6 but who knows? Indeed there is no A-333Gr65. He possibly also means API 5LX65. In either case they can be readily welded to A-106.
