Hi
I am looking for some calculation or information for stiffening of Blind plates for Hydrotest. The Plates avaialable aren't sufficient for the hydrotest pressure. The diameter of the pipe is 54". the wall thickness of the Pipe is 12mm. I tried calculating the required thickness as per the...
Are there any practical limits on fixing the Pump in /pump out rates for Floating roof Storage tanks ? Else, are there any limits on Floating roof velocities ? any relation to Diameter of tanks ?
I have a case of a 32M dia x 20 M height Cone roof fuel oil tank, the roof of which collapsed. The roof alongwith the truss structure caved in. At the time of the collapse, the tank had about 2 Metres of fuel oil in it. The tank had steam coils but there wasn't any transfer from / to the...
Dear all,
I would like to know the basis for calculating the relieving capacity required for a Mounded LPG bullet designed for 15 bar. What would be the basis for the exposed area of the vessel for a Mounded bullet in a fire case scenario, where only the Nozzle dome is exposed out of the mound ?
Does API650 allow for taking credit in the Design of Wind girders, when Wind speeds are less than 120 mph? Add-4 has introduced the Velocity consideration in the calculations in 3.9.6, 3.9.7. Wind velocity in my region is 87 mph. The resultant would be comparatively less no. of wind girders...
What is the relationship between Joint efficiency and Radiography per API 650 ? Can a Joint efficiency of 1.00 be used for design and Spot radiography be applied during construction. What is the normal engineering practice ?
Portions of a floating roof could have higher corrosion allowances (like the central deck, inner,bottom plate& outer rim of a pontoon, nozzles, buoys, appertunances exposed to liquid), while Top plates of Pontoons, external buoys not exposed to liquid etc. could have lower corrosion...
[b]I have to calculate the allowable nozzle loads (10" 1500#) on the inlet nozzle of a NEMA turbine. For this I have to calculate the equivalent area of the turbine exhaust for calculting the allowable nozzle loads on a NEMA SM-24 turbine, since the code specifies that I first calculate the...
Anyone out there with a vendor list of Split Tee manufacturers (conforming to ANSI B16.34) in the world ? Split tees are used for Equal size Hot tappings.
