    Welded Pipe Patches

    Thanks for the help Ralph. You're right; we almost always do a UT of existing pipe wall to ensure adequate thickness prior to repair welding. I'd seen the AWS Pipeline Welding & Inspection a while back - I'll look at it again. Thanks for posting, Nelson

    appliance charging via induction?

    Well yes I remember that half of Japan is 50Hz and the other half is 60Hz. The specs in the owner's manual say "AC 100-240V, 50-60Hz". I thought that the most interesting feature of the unit was that there were no electrical contacts on either the razor or the battery charger. That...

    VB programming for printing formatted text

    I program often in VB 6.0 but I have never seen a direct VB utility for printing formatted text. You need the VB reports module; I'm sure it is available in the Enterprise Visual Studio but I don't have the reports module. The reports module is VB's method for sending stuff to the printer.

I am getting ready to start a new job as an Oracle developer at the same salary, so I feel like one of...

    di water

    One way the pH can drop in DI water is if it comes into contact with oxygen. I have seen DI water (not yet treated for pH control) go from 7 pH to 5.7 pH following inadvertant aeration. A lot of applications require that DI water tanks be inerted, as with nitrogen, to prevent this.

    Titanium

    Don't know about feed rates and tooling, but titanium fines are flammable/explosion hazard so incorporate measures to collect and contain titanium dust.

    Welded Pipe Patches

    We receive "requests for temporary approval" from various ships who weld pipe patches on various piping systems with through-wall leaks. We disposition each request on a case by case basis. We do not know of any industry standard for pipe patch geometry, weld joint design (I am...
