Re: [MW:5326] Peaking & Bending Measurement of Welded Joints in Cylindrical Storage Tanks....

By Materials & Welding
Please,refer to API 650 Eleventh Edition, Addendum 2008, Numeral 7.5.2 Plumbness, 7.5.3 Roundness and 7.5.4 Local Deviations. All are very importand mesurement.

Dear Friends,

I am making fixed roof cylindrical oil storage tanks as per Indian
Standards IS-803.In section 9.3.5 it is mentioned about circularity
and shape.There it is mentioned about verticality & circularity
tolerences.Also it is mentioned about peaking and bending of welds
there..

1.Peaking of vertical weld joints measured over an arc length of 1 m
shall not exceed 12 mmm.

2.Bending of horizontal weld joints measured by a straightedge of 1 m
length shall not exceed 12 mm.

My questions are..

1.What is meant by this peaking and bending there?
2.How we will measure these factors?
3.How would the unit "millimetre" will come for these factors
measurement?
4.Is these 2 measurements are important in tank fabrication,if I am
checking vericality & circularity properly?
