Hi Kadir,   For pressure of 5Bar, you may define the thickness for IS 2062 based on dia, loadings on the vessel, and any more factors dictated by client spec, However for MOC (Chemical composition) we have to consider so many other parameters also like as… 1.        Fluid in service / Storage. 2.        Atmospheric conditions. 3.        Client specifications. 4.        Design life / No.of years for service… 5.        Any weight limitations.. 6.        Application (like as surge tanks i.e periodical loadings and to absorb surge pressures)… 7.        And as you required temperature also… As per IS 2062 – And as per your statement 160Deg C is a high temperature application, better you may refer ASTM A 515… (though a very negligible difference between these in chemical compositio...

Dear All. There are some issues and concerns about bolt and nuts:(please mentioned reference document) 1.If the ring gaskets are lubricated and bolt tightening have been done and no leaks observed during hydro testing, is it accepted or not?if not flanges must loose? 2.Unfortunately after tightening, C.S bolts and nuts are painted.is there a document that painting forbidden or not (especially for sour service)? 3.B7M bolt and nut have rusted before tightening, are they must be derusted or not& how?rusting can affect on torque value? and regard to any leakage observed can be assured that min required tension are applied on bolts? 4.Is there a technical document that investigate effectiveness of Hammer tightening vs. of wrench and tensioner?
