We are now approaching 20 Dec, 30 days after this plea.
(Robt wonders if the interview was successful in revealing the qualifications for a Senior Reliability Engineer at SpaceX.)
Why is the "trailer skin (?) thermal expansion" causing instrument measurement difficulties?
Seems the instrument would have to be mounted on shock-proof or very resilient mounts to avoid damage while the trailer is being pulled, when the trailer frame itself is bent and twisted loading and...
On two levels, it can hardly be otherwise: A welder cannot "be qualified" on a WPS test weld if that WPS itself is not yet qualified.
On the other hand, should YOU (your company) always chose your best welder (of those available) to make the certification welds for a new WPS?
Your "best...
Rational limits apply "first".
Example:
- Dye Pen exam or UT exam MUST WAIT until the weld zone has cooled down to near-room-temperature. The dye and UT lubricant/sound seal goop needs time on a relatively cool surface to soak, to not be burned off by a hot weld zone.
- VT? Often, can be...
I regularly use 6 and even 8 inch NPT threaded fittings on temporary lube oil pipe assemblies for flush fittigns and lineups. But those are temporary use, low temperature (60 to 150 deg F) and low pressure assemblies.
Every threaded fitting MUST BE allowed to be screwed tight, then not...
Purchased a new NiCd razor. It has an old-style external (1.5 volt DC wall plug-in/cheap Chinese) charger/inverter.
No apparent "controller" or regulator like the more modern LiOH batteries and regulators.
Will I gain anything useful by fully discharging it to 0.0, then recharging? Or just...
Liability and the "pursuit of accountability" might be difficult:
"Pemex took full ownership of the Deer Park refinery in early 2022, acquiring Shell SHELL's stake in a refining joint venture. Mexico had acquired the facility to become more self-sufficient in gasoline and diesel."
The Mexican...
An open question about pipe supports in that 3D image. How is the sliding small pipe support under the 1 inch (1/2 inch ?) pipe coming off the bottom of the large elbow expected to "only carry" the small weight of the 1 inch pipe?
Would not the massive weight of the large pipe and its...
I was told on a different thread on www.freerepublic.com that the excess fuel was burning off while being "drained" out the bottom of the stage by gravity after landing (being caught in the twin arms). Disconcerting to see open flames after a landing - Certainly NOT what I expect after an...
I share Little Inch's reservations about the access to the large flange nuts and bolts for removal (of the bolts/studs) and torqueing of the nuts. (Add access and torqueing of the small flange nuts and fasteners too.) To resolve assembly and maintenance concerns, move the fitting out towards...
Received the Loctite 222 as recommended.
Is squirting phosphoric acid into the 3/8 tapped holes recommended, or "bad idea", to convert the rust before threading the new setscrews? https://files.engineering.com/getfile.aspx?folder=81ad5c87-6038-4d1d-8301-e0ab4f955d45&file=Setscrews_As-Rusted_2.jpg
As concerning as the external (visible) general rust and untreated corrosion is,
- and the near-certain probability that "several specific points" with the internal corrosion on the salt-water "puddles" deep in the bottom and the sagging middle of the three or more of these pipes have locally...
Accurate, helpful info. My symptoms match the (Default, or "Incorrect For Me") setting for this Setting.
I will reset the value.
From your link, the following is repeated:
OSNAPCOORD (System Variable)
Controls whether coordinates entered on the command line will override running object...
The weld was made with NO PREP and without removing the paint from either surface. SO the interior of the weld is well, "as good as the burned paint inside the weld".
A mark of the lack of quality: The weld slag was not removed after cooldown. So what ever is there still cannot be looked at...
I am going to (reluctantly and rarely!) disagree with all of the above.
For ANY FLANGE, you MUST order by ALL of the following:
Nominal diameter
Material (and sometimes with certification papers)
Type of flange and Flange face: RFWN, RFSO, RFSW, FFWN, API style, etc
Class or "Pressure...
Aluminum tube frames - perhaps 1 x 1 hollow. Velcro attachment method. So, a lightweight item is being positioned.
Probably not a welding jig or fixture, but a #D adjustable "assembly jig" nonetheless for a 18 inch x 18 inch x 18 inch assembly that needs to be re-positioned regularly...
Snap is "off" Grids are "off"
OSnap defaults are Cen, End, Insertion point (for blocks), Intersection. I really don't want to continually change these either.
But. When I run a line (or dimensions, or move a point to a new point) particularly when in a complicated area with a lot of...
Thank you. Why was my assumption that the (slightly more expensive) SSTL setscrews incorrect? Or simply not needed compared to sealing the threads chemically?
