Pipe to Pipe MS Flange Connection for Chilled Water

[siril kumar]

Hi Everyone,

We will have to do pipe to pipe connection through flanges. Our Pipe is 400 mm ID/ 8 mm thick MS Pipes. Fluid is chilled water from 7 to 25 Deg C. The Pressure on the Pipe Shall be 11 KG/cm2.  I am primarily referring 2 standards: ASME B31.3 & MSS SP-44.  B31.3 is primarily for the process Pipes. So I want to understand:

1) For chilled water can we refer any other standard other than 31.3

2)  For pipe Flanges  other than Standard of MSS SP-44 can we refer anything

3) Does IS/ BS Standard which refer flanges in Table give any reference to Pipe to pipe flange Standard 

Thanking you in Anticipation

Regards,

Siril

better to refer to B31.3, considered a potable water line only temperature (7 to 25).

Dear All,

There is Nozzle of 20" dia should be welded with the Tank shell ( A fillet Joint). What should be the max allowable gap between shell and Nozzle.

Is 4mm gap is allowed?
