Peaking & Banding | PPT - SlideShare
May 14, 2020 · Peaking and banding refer to the roundness and straightness of shell plates around vertical and horizontal joints in storage tanks. Peaking is measured using a horizontal sweep board along vertical joints, while banding is measured using a vertical sweep board along horizontal joints.
What you mean by peaking and banding? - Bayt.com Specialties
Apr 7, 2015 · Peaking & banding is nothing but the profile of the tank i.e while erecting the shell plates the curvature to be maintained. The shell plates rolled to a radius to be maintained till the welding of joints completed.
CNT on Example de Peaking and Banding - AST Forum
Jan 7, 2010 · Peaking is when the Vertical shell weld or weld joint is not properly fit up and it makes a peak at the joint. Sometimes this is caused because the shell plate wasnt properly rolled. The radius of the tank in that area will not be correct.

peaking value - American Welding Society
Jul 25, 2009 · I refer on ASME VIII Div.2 (2008a) Part 6 paragraph 6.16.3 C, peaking value shall be determined using paragraph 4.14 but when you go through 4.14 it only details the evaluation of vessels outside of tolerance (i.e. shell tolerances, local thin areas). Hope you can help me out.
Tank Peaking/Banding Issue, API 650 - Google Groups

On bending stresses at longitudinal weld joints of cylindrical shells ...
Jan 1, 1994 · Bock and Zeman [345] proposed a power-series approximation for the local type of peaking in welded longitudinal joints of cylindrical shells with angular misalignment of the cylinders. Good agreement with the FE analysis was noted.

Check the gap between the sweep board and the tank shell and note down the value if there is. considerable gap (beyond inches or 13mm). For a more accurate positioning of the sweep board, slide the board. horizontally to fit it properly to the tank shell. A torch light & scale/measuring tape may be used to assess the gap.
