hii eveyone ...do you know where I can  get the correct torque values for metallic flanged joints of sa193 bolts used...thanks...

RE: correct torque...

If you run a Google Search for "Torque Value" you get a lot of answers, mainly tables where you can look for the data you need.

RE: correct torque...

look in ASME PCC-1 "Guidelines for Pressure Boundary Bolted Flange Joint Assembly "- it give a torque table for 50 ksi

RE: correct torque...

emrekop,
        Bolt torque requirements are dependant upon the actual bolt load requirements of the joint. The physical dimensions of the gasket and the material of construction will determine the minimum, maximum and optimum seating stress requirements. External loads as well as pressure will affect the bolt loading requirements to ensure that the minimum seating stress in maintained whilst not exceeding the maximum seating stress of the gasket. To provide a bolt torque for a joint is not easy to do without knowing all of the dependant factors which could affect the required bolt load and hence torque. Also remember that if a bolt torque is given the actual bolt tension applied to the bolted joint could be in excess of +/-30 % of the anticipated value.
