I need all the key dimensions for Figure 1502 hammer unions from 2-4inch. I know this is not an organizational standard (e.g. API, ASTM, etc), but there is an industrial standard (thus the whole Fig system start by one company) which all the manufacturers comply to so that the fig. 1502 female...
Who's standard are these ports made to? I see several manufactures that make MP C&T fittings and valves/manifolds with female C&T ports, but none of them mention the specification reference. Is it an ASTM, SAE, Mil, et.c spec? Is it Autoclave proprietary but now made by any one? I'...
Answered my own question. It required me to actually read [smarty]. The Basic Diameter is the minor diameter of the internal thread. This is not stated on or under the chart. It was is the reading a few pages before (pg 1792)
I'm looking Table 2b (Gen Purpose American Natl Standard Single Start Screw Threads) and Table 3 (Gen Purpose Acme Single Start Screw Thread Data ASME/ANSI B1.5-1988) on pages 1797 and 1799 of the Machinery's Handbook 26.
Table 2b states that the maximum Minor diameter for a 3/4-6 thread is...
I'm thinking that "may" not be correct unless they did the drawing incorrectly. On this particular drawing, they have the number on the right of the z regardless of where the leader is.
I know that with ANSI/AWS, the size is always to the left of the symbol and the length is always to the...
I have a fabrication drawing from the UK that has a z3, z6, and such in front of the weld symbol were weld size usually goes. What does that mean? I doubt it means 3mm, 6mm, etc. since it is on an aluminum structure.
Q=AV , where V ^2= P/(density[1+loss/2]) and A = pi x r^2 was taken from my "Fundamentals of Fluid Mechanics" book published by John Wiley & Sons Inc. (see attached). Please feel free to call and correct them, zdas04. There may be a flaw. I certianly don't see a time unit source in the...
There's also another thing I'm trying to figure out. I that equation....
Q=AV , where V ^2= P/(density[1+loss/2]) and A = pi x r^2
..... Q is volume/time. Where did the time come from? Velocity, yes, but the equation for velocity has Density and Pressure, neither of which have a unit of...
I'm pretty far removed from flow dynamics, so please excuse the elementary question.
A technician is testing a oil pump at my work place and taking flowrate data at a given output pressure. The output pressure is being set by a needle valve.
These are some of the points:
0psi ---- 39GPM...
I often have problems with getting products made in the US that were designed in the UK? Machine shops are always asking for substitute materials. I prefer to use what's specified whenever possible.
In this case UNS C72420. Where can I get it from? If no where in the US, then what high...
Until I can find some way to know for suer, gut-feeling-calcs suggest that it should be ok if nearest machined feature is 18 inches away.
I guess what needs to be known is, at what temperature will the pipe shape be compromised and will it reach that temperature 18 inches from the weld on a 24"...
I'm designing a receptacle using A106 B 24" sch 60 pipe. The ID will be machined for a very close fit to what goes inside (.01" gap). This pipe the be welded to a large plate. I'm trying to figure out the minimum length to make the pipe such that the welding will not effect the shape/size of...
We had the output shaft of a torque wrench fail. The torque wrench is rated for 3200 ftlbs. The square output shaft is practically 1.08 inches square. According to the formula I used [ Max Torque = (2/9)x shear stress x(width of square)^3, where shear is .42*yield], the shaft would have to be...
