vessels verticality tolerence as per the code

[Mathew Bosco]

Pls  anybody give the info

what is tolerance for verticality from top to base of any vessels as per the code.

guide me 

wilson

[george....@gr.bureauveritas.com]

Manufacturer has to declare to what tolerance does he produce the products. There should be some company inhouse standards for all dimensions which are not covered by code.

Verticality is affecting instability (buckling).
It is up to the designer to fix this tolerance in accordance with the allowance taken during the calculation.
If the vessel is already installed and verticality is not perfect, it has to be calculated again using the actual and not the ideal geometry.

This is a requirement resulting from:
ASME BPVC Section VIII- Div. 1: U-2(a), U-5, UG-22
or
ASME BPBV Section VIII-Div. 2: Table 4.1.1

That's a bit high. It shd be mentioned as subject to max of 10mm or similar

10mm per mtr. Is a common criteria regarding structures..but up to a maxm. Of 50mm only.

[Jorge Mejía Lema]

Please see it at API 650 for Welded Tanks for oil Storage as a guia. Numeral 7.5 Dimensional Tolerances.
Plumbness from the top to bottom 1/200 of the total tank height.

 7.5.3 Roundness  and  7.5.4 Local Deviation.

[Ahmed Husain]

Normally, PIPs are referred as guidelines for verticality of pressure vessals. A. Husain

[Shashank Vagal]

For structures alone, AWS D.1 has it in 5.23, if the codes do not conflict.

1mm foevery mtr is a standard usually used ,

[Thota Kishore]

Sir,

Pls refer Api650 cl.7.5.2 for plumbness of tanks. This may be helpful to you.

[Karthik]

Hi,

Please find below the tolerance.(According to Pressure vessel hand book).

Deviation from verticality.  = 1. for vessel up to 9 meters. overall length <±13 mm. 2. for vessel over 9 meters. overall length<±3 mm/300 mm. or max.38 mm.

 

Thanks & Regards,

Gents,

This info is available from Total GS for PVV:

5.6 Deflection

Lateral deflection of vertical vessels under the effect of dynamic loading shall not exceed the

following:

• Columns with internal trays:

300 / H

• Other vessels:

200 / H

Where H = Total height of the vessel and support.
