Leaks are one problem. Another is dissimilar materials, i.e. metal into plastic, or plastic into metal.
If it is metal into plastic and the metal is high end or the spec or oversized or the plastic is undersized then the method of number of turns can cause a real problem with the plastic...
There is very little you can do to change the attitudes of upper management. Whatever system put them in upper echelons is the one they know, understand, and at this point prefer.
If you can manage to do good and look good at the same time, since they are not always mutually exclusive, you...
And sometimes engineers turn into artists - Alex Calder being the most notable.
Understanding people is integral to the success of any product or project. Arts and humanities can give insight into peoples wants, desires, motivations and preferences.
If it is a hazard that means someone's life, limb or livliehood could be lost. Any one who percieves the hazard has a duty to see that it is reported and corrected.
I have done many searches looking for recommended torque by size and material for threaded pipe connections. Almost all sources give a "number of turns" method. Does anyone know why torques are not used?
Just a general question a driver for you traffic engineers from a Manufacturing Engineer. The city of Tucson, AZ instituted "Lag Left" turn signals a number of years ago. The story was that it would move more vehicles thru the left turn lanes since some would get a chance to turn...
A little more on Eiffel
I know of at least two structures by Eiffel that are in North America. One is the supporting stucture for the Statue of Liberty in New York Harbor. The other is an all metal church in Santa Rosalia, Baja Sur, Mexico. Any one know of any others works by Eiffel in North...
Evaporative or swamp cooling is not very effective if the relative humidity goes above about 30%. It will also raise the humidity considerably in the shop, which may or may not be a concern for your product and equipment. I have seen a heat exchanger type evaporative cooler where the...
I am looking for information on the accuracy of visual assessment of angles, specifically how many degrees off of parallel or perpendicular do two objects (medium size 1 foot to 4 foot range) have to be for someone to notice?
Just a list of what comes to mind: screws, nuts, bolts, clips of all kinds, hose clamps, C-clamps, magnets (mostly for paper to enameled steel), string, rubber bands, buckles, snaps, buttons, zippers, latches, fun-tac putty, and on and on.
This is from a website I found on tube bending while looking for something else. Unfortunately I didn't note the URL, but I did print it. Here is their formula.
Measure or calculate the length you need along the centerline of the pipe as if you had sharp angles. Bends will "add"...
