API 5L and fittings

[Bracus]

Hello. My name is Denis. I am the Russian engineer. I know materials of pipes for linear pipelines in Russia. They very strongly differ from materials on pipes according to API5L and ASTM. On this site

http://www.pipingstudy.com/piping-material-combination.html

I found compliance:

1. API5L Gr.A -> ASTM 234WPB -> ASTM 105 ->ASTM 216WCA -> A285 Gr.C

2. API5L Gr.B -> ASTM 234WPB -> ASTM 105 ->ASTM 216WCB -> 515GR.60

Help to continue the list for PSL2:

API5L Gr.42 ->?
API5L Gr.52 ->?
API5L Gr.60 ->?
API5L Gr.65 ->?
API5L Gr.70 ->?
In what document it is possible to read it?

Best regards.

Sorry for my English.

API 5L and various ASTM Standards. You may notice , the GOST were abstracted from the API 5L and 5 CT . A pretty clear connection 20 yr ago. Differences like shorter range lengths because of shorter Russian railroad cars.
Hope this is legal ; Russia has (20 yr ago ) most beautiful steel mill workers in the world.

blacksmith37, Thank for your reply.

Elaborate on the issue.
The pipeline 10 MPa, 30 .. 40 ° C
Following the calculation of the gas pipeline I got a the pipe 20 "(500mm) 0,500 in (12,7 mm) API5L X70

I need to choose the materials for the tee, elbow and flange.
I use flange B16.5, elbows and tees I use B16.9.
B16.9 refers to the A 234 / A 234M - 04. here is the following grades
WPB, WPC, WP1, WP12 CL1, WP12 CL2, WP11 CL1, WP11 CL2, WP11 CL3, WP22 CL1, WP22 CL3, WP5 CL1, WP5 CL3, WP9 CL1, WP9 CL3, WPR, WP91, WP911. Let's say I choose elbow 20 "(500mm) 0.5in A234-WPB, and tee 20x20" (500mm) 0.5in A234-WPB, A105. Is this correct combination?
API5L Gr.70 -> ASTM 234WPB -> ASTM 105

Best regards.

ASTM A860 might be a better choice for fittings in an X70 pipeline.

I have to ask, why are you going to X70 grade pipe. That pipe is difficult to weld and the fittings will cost a lot more. An X60 will give sufficient pressure rating unless the pipeline is being built through a large city.

Use A694-F? for forged, A860-WPHY? for fitting, A352-LCC for cast, A516 for plate. You shall suit the sch for not equal API-X?? grade.

if7005, dcasto, SJones, blacksmith37!

Thank you for your help!
I'll go learning codes and standarts ASME, API, and ASTM.

Best regards.

You really want to buy flanges or fittings, not the materials. The flanges and fittings that correspond to high strength grades of API 5L Pipe are ordered as flanges fabricated to MSS (Manufacturer's Standardization Society) SP44 or fittings fabricated to MSS SP75. You only need to specify the grade you require, as WPHY-70, or whatever grade yield strength you are using in Ksi (1000s of psi), eg. WPHY-60 = SMYS of 60,000 psi. There is no need to specify the exact material to make (unless you feel an overpowering need to do so) as the materials permitted to be used to obtain the specified yield strengths are already contained inside the MSS spec. WPHY = Wrought Pipe High Yield.

If you only need strengths corresponding to low alloy carbon steel strength (35 ksi), then order ASTM A234 WPB, or ASTM A105B for flanges. Again, those specs specify the required results for manufacturing fittings or flanges reaching the B strength of 35ksi, respectively, not the material itself.

BigInch, thank you for your reply.

I can not argue with you or accept you. I still poorly guided in the standards API, ASME, and even more so in MSS. And while not quite understand technical English. please, кecommend me a book or books that not only tells the pipeline, but also the correct choice of materials, strength classes, preparing specifications according to standard API, ASME, and MSS, and so on. The order of this choice.

Best regards.

Read the specs.
