A threaded brass plug screwed into a threaded brass coupling will corrode and become fused together when subjected to warm humid air and undisturbed for a long period of time (10 or 20 years). Since corrosion removes metal, how is it that the plug cannot be removed after it apparently corrodes...
I have acquired a 25-year old “cryogenic cooler”. The manufacturer sells the stainless-steel insulated box in various sizes and cooling configurations to suit a customers needs. They don't all cool to low temperatures but may cool to temperatures well below -100C if you have enough LN to throw...
I have a 4000 psi quick-disconnect that ejected the plug. It may have been subjected to higher pressures than 4000 psi. Does anyone know if quick-disconnects will first rupture or will it fail to hold the mating fitting when subjected to excessive pressure?
One-pin vs. a two-pin flange?
A contractor indicated that they would rather have a two-pin flange rather than a one-pin flange when connecting to a piping system that had a 20-inch Megalug flanged conection.
Can anyone point me to a source for corrosion rates of steel pipes that are located inside a building (dry conditions) that are used for kitchen waste water? Waste-water in general would be OK.
I am trying to determine the remaining service life of a 60 year old building drainage system. I...
