X40 pipe ?

Date 01-25-2012 23:51

Most all work i've done in the past we use 8010 on X60 X70 anything below has been 7010,
What would the reason be to use 8010 on X40 pipe?
The test was standard 1104 12" bell hole 5p+ bead 8010 rest way out.
The pipe to be used for the job was 4" sch40 X40.

Thanks rj

Hi

Difficult to say if there is a good reason, but sometimes the stresses that will be placed on the pipeline during the installation process may exceed the yield stress of the material. In these cases, they want to make sure that the plastic deformation happens on the base metal and not the weld, and will consequently specify overstrength filler metals. (e.g. if the pipe is to be reeled for laying off-shore from a barge.)

Or maybe they just had too much of this filler, and needed to use it? :smile:

Thanks
this is just fabrication at an oil station all above ground.

Ladies and Gentlemen,
I am a CWI graduate engineer and have never heard of a standard weight schedule 40 NPS pipe being X40. Black iron pipe ASTM NPS is A-53 steel. The X-40 is a designation of API oil field tubular line pipe with different dimensions. I have never heard of a X-40 API. The lowest number I heard of is an X-48. I hope this is helpful.
Sincerely

Ladies and Les (CWI graduate engineer),

Oil field tubular products are a different animal than API line pipe.
There is no X48. There is X42, X46, X52, X56, X60, X65, X70 & X80.
Those can be made to a schedule size or an API size. API size most often.
There is also multi grade baby size pipe made to A-53 grade B/API X42 (or API 5L gr. B). That's fairly common.

JT, not a CWI graduate engineer.

JTMcC,
Recall X48 in a NYC job in the trench with broken sewer line "water" going towards back CWI'ing with perspiration! You seem more knowledgeable than me on the matter. If I was betting my job I would contact API and/or ASTM and/or the pipe parallel organization. Having paper does not mean clean work !
