nitric acid high in iron - Corrosion engineering - Eng-Tips
2003年10月9日 · for strong acids you shouldn't be pulling iron out of your tank wall in the time it takes to haul it. by the way that is several lbs. of iron /load. that is a lot. suspect that you are getting Fe contamination from storage. you need to take samples at …
Anti siphon hole in dip pipe - Pipelines, Piping and Fluid …
2006年11月30日 · If used to reduce electrical charge that would otherwise accumulate from solvent "free fall", dip pipes can sometimes be replaced by an attached angle iron letting the liquid flow down the angle iron, or simply by cutting and removing one metal strip off the 2-in pipe along its whole length inside the tank. No anti-siphon holes would then be ...
API 579 - Dent vs Out-of-roundness 1 - Eng-Tips
2024年12月12日 · Basically, the localized dents occurred in the area circled in red, where an angle iron was welded internally to the shell. The circumferential deformations took place just above the area circled in blue, which corresponds to a flat end (mirror).
Allowable Shear Stress 3 - Eng-Tips
2001年8月10日 · The bolt is "pulled" through the bolt hole axially shearing the material of the plate with the bolt head. Therefore I would use plate shear strength according to vonlueke, thus 0.577Sy (Sy = yield strength) is equal to the shear yield strength of a ductile material. For Cast Iron it would be basically the point where it fractures.
Pipe Thread Stength - Mechanical engineering general discussion
2008年10月17日 · The allowable stress for a low grade Carbon Steel pipe is 15ksi at ambient, that would allow a 390 lb load. If it is Mallable Iron, 10ksi would be an allowable stress which would allow you a 260 lb load. For a sch40 nipple. Use a sch80 for safety. Allowable Stress does not equal Ultimate Stress.
Bottom Chord Failure of Wood Roof Truss - Eng-Tips
2021年9月6日 · Should have four smaller come alongs, two on each broken end (pulling perpendicular to the trusses). Then each broken ends can be kept aligned as the truss is compressed. Adjacent intact trusses can be temporarily braced together to anchor the reaction end of each of these four smaller come alongs.
