Dear Mr. Jose Sebastin The sket you attached itself is self explanatory. Distortion at the longitudial weld and circuferential weld are measured with these templates and it shall not exceed the figure you have given. For further clarification please feel free to call me on 09892193345 ( Mumbai) Gopu

2010/5/31 jose seban <joseseban@gmail.com> 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?

Jose Sebastian,
