    ASTM A106 Marking requirements-below 2"

    Thanks Metengr. I understand your comments. My concerns: A106 specifically states: "For sizes 1 1/2, 1 1/4, 1, & 3/4 EACH LENGTH SHALL BE MARKED". A106 also states that for sizes less than 3/4", the marking may appear on a bundle tag. Since A106 is the prevailing spec, it supercedes the...

    ASTM A106 Marking requirements-below 2"

    A106-B states that marking shall be per ASTM A530. A530 allows bundle tags for sizes below 2" Nominal Diameter. In A106 however, the material spec specifically states that 1 1/2", 1 1/4", 1" & 3/4" SHALL BE MARKED per A530. My interpretation is that A106 intends for each lenght of pipe in...

    Recommendations--steel bulkheading

    I have a client that is looking to install a bulkhead at a freshwater lake. The contractor has given the following options for steel which will be driven into the soil in shallow water: 5 gage-black steel OR 8 gage-galvanized steel I welcome any suggestions or recommendations.

    Referee Standards in ASTM A691 & B31.1

    Metengr, The pipe will be provided in the N&T condition. The issue specifically relates to the tempering temp--B31.3 (704-746) VS A691 (590-745). The 650 that has been applied to the tube is not acceptable. Pls Also note: the 540 mentioned in the orignal post was a typo! Tks,

    Referee Standards in ASTM A691 & B31.1

    Thanks metengr. Upon further research I see that the B31.3 HT requirements have specifically been imposed for the longitudinal weld seam by the E&C---KBR. Don't guess I have a way to circumvent the issue since it's imposed by the client.

    Referee Standards in ASTM A691 & B31.1

    We've recently purchased 30" X .812" A691 1/1/4 Crome pipe from a European producer. We're now finding that the pipe should have been manufacturered to the B31.1 requirements which have a slightly higher tempering temperature than is required by the ASTM spec--details as follows: Post weld...

    Welded A/SA 691 P91 pipe VS Smls A335 P91

    Thanks metengr for your post. Unfortunately I do not have a copy of Section I. I work for a large seamless pipe producer and am trying to get a copy from our office in Italy however, to date no luck. Can you elaborate further on the information on Pg-9. Specifically I'm trying to verify the...

    Welded A/SA 691 P91 pipe VS Smls A335 P91

    Further to my previous post and recognizing that A691 is not an acceptable material under Section I, does the same hold true for welded pipe produced under ASME SA671 and ASME SA 672?

    NACE MR 0175 Requirements

    If I recall correctly, HRC 22 is close to a Brinell hardness of 241 which has an equivalent tensile strength of appx 118,000-120,000 PSI. A516 Plate will never achieve these values under normal heat treat conditions.

    A/SA 691 P91 Welded Vs A335 P91

    A number of years back I worked with a domestic E&C getting A/SA 691 P91 pipe approved for use in Power Plant construction. After months of testing and qualification in Europe, the welded pipe was finally approved. I am trying to understand the current B31.1 and Section 1 requirements related...
