Bookmark or Share- How to change units without converting! - Eng-TipsIf you must scale the entire part, you need to scale all linear dimensions. If you can not automate this, you may miss a dimension or two in the midst of the blinding tedium. To avoid missing any dimensions, first export your model, import it to a new part file and scale that. Overlay the two parts in a temporary assembly.
- Eng-Tips is the largest engineering community on the InternetThe Omega (overstrength) factors should only be used where specifically called for in the code. Typically these are applied to connections and other items that would tend to fail in abrupt rupture (i.e. brittle things) vs. elements that can fail via yielding and help the structure absorb the seismic energy.
- Mud Mat as Structural Element - Foundation engineering - Eng-TipsA mud mat (or blinding concrete) is never a structural element - would not count on it for any strength or load distribution. Had a client in a former French Colony in SE Asia who was upset that for a foundation excavation (which the contractor had excavated a bit too small in one corner) that we had placed the mud mat on what was open and then ...
- Two valve Isolation rule - ASME (mechanical) Code IssuesSafety programs require common sense and must be controlled by the organization that owns/operates or repairs hazardous equipment. With that said, in certain applications - for example separate boilers (not twin furnace boilers) that feed into a common steam outlet header the ASME B&PV code requires a stop and check valve as a form of double ...
- B16.5 Blind Flange - Best Practices - Eng-TipsThe thickness of a blind flange in B16.5 is depicted as being exclusive of the raised-face, and paragraph 6.3 states you are allowed to remove the raised-face to create a flat face flange. This leads me to believe the corrosion allowance would equal the height of the raised-face (1/16" for CL150/CL300, and 1/4" for CL600->CL2500).
