Q: I am designing a gas pipeline as per ASME B31.8. The specification calls for API 5L Gr B materials pipes. Can I replace this pipe material with ASTM A106 Gr B which is readily available in local market? Please give technical justifications. Thanks!
A: Each supplier of mentioned materials can provide you with their chemical & mechanical properties, their equivalents and purposes. As the designer (an expert) of particular pipeline project, only you must overtake decision and responsibility which material to apply! Nobody else will do it instead of you! As an expert in this field you have sure some specialized institutions that you can consult, but last decision will be always yours.

Gr. "20" acc. to GOST 1050 is equivalent to Gr. "B" acc. to ASTM A 106/A53.. For Casing and/or Tubing pipes sometimes grade is not indicated at all and indicated only a letter as "K", "D" etc. acc. to related yield and tensile strengths. The same in API standard designated for Oil & Gas Industry mostly used Grades as "B", X42 X52 etc. Also other grades applicable acc. to relevant standards DIN, EN, ASTM.

Q: How can I get to know all inquiries for aluminum tubes and pipes? (asked by: firstname.lastname@example.org)
A: Dear Mr. Anant Shri Kajaria, This is a very good question! There are two ways:
1) As a FM (free member) you can request basic data of all companies, which have posted inquiry or offer ads. You will get them for free, chronologically ordered (by dates), in an Excel table with an empty Manipulation Column (MC). Go through posted ads and mark interested ads in MC as e.g. Al-P (P = purchase). Sort then your Excel according MC, hide un-necessary columns and copy & paste interesting data in a Notepad and from it in your working database. As a FM you can also see in the Special directory how many companies, which have jointed their products, buy and sell Al - pipes.
2) As an EM (exclusive member) you'll get automatically basic data with short program description of all companies currently added in the Special directory and its monthly updates. Go to the Special directory, click at Products and then at Group 21000. Find interested Al - pipes. You can click at product's code to get them all or at suppliers or purchasers. You'll get the relating companies in an alphabetical order. In your MC you can mark them as Al-P (purchaser) or Al-S (supplier). There are much more companies in Sd without jointed products. To include also them in your working database, sort your Excel according short description and make then fine research in Program description from the interesting companies using this web site.

Definition of buttering from ASME Section IX, QW/QB-492 Definitions:Buttering: the addition of material, by welding, on one or both faces of a joint, prior to the preparation of the joint for final welding, for the purpose of providing a suitable transition weld deposit for the subsequent completion of the joint.Simply it is weld build up of (one or both) base metal(s) before beginning to weld the joint itself. This can be done in order to make up for poor joint preparation as indicated previously, but also is done to minimize the effect of PWHT on a sensitive material or eliminate subsequent PWHT. For the latter cases a couple of examples may be in order:1.If you wanted to weld P91 pipe to a stainless steel pipe, ASME Code would require a PWHT of the P91 at nominally 1400F (760C). This temperature would, however, “sensitize” the stainless steel (cause carbide precipitation along the grain boundaries). One way to eliminate this problem is to butter (or overlay) the P91 with ERN…

Level PSL 2 has additional mandatory requirements for chemical composition, notch toughness and strength properties and additional NDE. Requirements that apply to only PSL 1 or to only PSL 2 are so designated. Requirements that are not designated to a specific PSL designation apply to both PSL 1 and PSL 2.The pipe grade for PSL 1 pipe is identical to the steel grade (designated by a steel name). It consists of an alpha or alphanumeric designation that identifies the strength level of the pipe and is linked to the chemical co…
