    Allowable Loads/Moments on Tee Joint

    You are right, I do not have complete geometry information about the tee joint. Till now what I have done is modelled two intersecting cylinder of 16in. diameter at right angles to each other. This result in a sort of singularity at the intersection. I do not know how to remove this...

    Allowable Loads/Moments on Tee Joint

    Hi : For use in a 16in pressure vessel, I am trying to calculate the allowable nozzle loads on a 16in Tee. Can someone tell me how do I calculate the allowable loads per ASME pressure vessel code ? Thanks Kapil,Cincinnati

    Yield Stress for Brass Bulkhead Coupling SAE CA360

    Hi, I am looking for yield stress for this material CA360 "Brass Bulkhead Couplings". Do any of you know the value or if someone can point to reference that would be great. Thanks Kapil,EWT

    Nozzle Loads : Allowable for Thermal,Seismic,Weight+Pressure Load

    TGS4, After looking at table 5.3, as suggested by you, I have few questions. The seven load combination does not consider the nozzle loads due to thermal expansion/contraction. Does it mean per ASME, I need not check for thermal loads at all and only consider the load case 4) D+0.7*E ...

    Nozzle Loads : Allowable for Thermal,Seismic,Weight+Pressure Load

    Hi. The nozzle loads as per the customer spec. includes loads due to (Weight+Pressure),Thermal and Seismic. Now, Customer wants us to add all these loads and qualify the nozzles. I am using WRC-297 for stress calculation. Now, simply adding these loads and checking against the Local Membrane...

    How to design Reinforced Blast Doors

    Hi, I am currently working on designing a blast resistant door per TM5-1300 (Now UFC 3_340_02) Manual. The parameters (Blast door is double leaf 187.5 X 196 in, each leaf supported on two sides)are such that using a 2" thick steel plate results in support rotation angle of 3 degree. Now...

    Modelling Piping T Joint in Ansys

    Hi : I am trying to model a Tee-Joint Piping in Ansys. What I have done so far is modelled to 2 cylinders of 8 inch radius intersecting at 90 degrees to each other. Next I am trying to create a fillet area of 24 inch radius at the intersection. However, Ansys is having trouble creating that...

    ACI 318- 05 : Load Factor for Seismic Loading

    Hi : I am designing anchor bolts per ACI 318-05. I have seismic g loading's of 0.6g in horizontal and vertical direction per IBC 2003, and this is the only load I have to consider. What load factor do I use for my calculations per ACI 318-05 ?

    Flow Through Pipe, Reaction at Hangers

    Sorry, I was not clear in my last post. The question was to determine the reaction force on the hanger. Now, While applying the conservation of momentum, will the reaction force on each elbow be the same or would it be different. What is the worst case scenario ? Thanks, Kapil,EWI

    Flow Through Pipe, Reaction at Hangers

    Hi : I have a system to pipe network, consisting of 4 Pipes and 3 elbows (90 degrees). Fluid Flows through one end of the pipe at a pressure of 35psi and flow rate 2787 ft^3/min and leaves at pressure of 20 psi from the other end. Now, my task is to design the pipe hangers, which would have...

    Friction Value b/w Stainless Steel Clamp and Neoprene

    Hi All : I need to figure out the pull out load in an expansion joint. The joint consists of two aluminium pipe, with a 1" gap and covered with Ventglas (a heavy glass fabric double-coated with duPont's Neoprene(polychloroprene))and which is clamped at both ends with Stainless Steel Hose...

    Screw Size for Hose Clamp

    Hi : I am trying to figure the bolt preload due to torque on the clamp. But I am not able to figure out the size of the screw used for this clamp. The max I know is they say use 5/16" hex nut driver to tighen it. Can somebody help ? These are specs for the clamp ...

    Hose Clamp + Friction Force

    Hi All : How do we find the axial load a pipe a take before it slips from the Hose Clamps at the expansion joint ? I have two aluminium pipes wrapped around by Ventglas Sheet( Forming an expansion Joint). The Ventglas sheet is clamped to the aluminium pipe using 4 hose clamps, two on each...
