Re: Hydrogen Embrittlement

perhaps it was just that particular MODEL....which was built about the time I was born. I specifically remember directing the crew that cut the unit up and scrapped it under the direction of a fellow from Exxon who had done the same thing at 2 other locations....because they were too dangerous to co...

Re: Hydrogen Embrittlement

I am pretty sure that the use of Hydrogen in the petroleum catalytic process has been discontinued.... as I mentioned, the last refinery where I worked (in the middle east), had the last running hydroformer in existence - and we shut it down while I was there (in the 1980s). Unless something new has...

Re: Drilling to depth?

no, because these 'finger feed' drill chucks have only so much axial travel.

You set the quill so that when the finger chuck is at the bottom of its travel you are where you need to be for the drill.

Dianne:

do it in the mill....you will need the positioning accuracy for the holes

if you want 'feel' then get one of these small drill 'finger' chucks that you can feed by hand.

Re: Hydrogen Embrittlement

in the petroleum industry, hydroforming is a very different concept from using hydraulic pressure to form metal. In a refinery, HYDROFORMING is (was) a process which while popular in the 1940's has totally disappeared from the business. Technical description: "a process for producing high-octan...

Re: Compressor woes

As a suggestion going forward:

My air compressor is on a 20 minute timer that must be manually reset if I want it to keep running.

This allows my wife to 'push a button' to get air in the garage for tires then drive away...not like I EVER have to worry about her shutting things off (giggle...)....

Re: Hydrogen Embrittlement

Ever hear of Hydroformers in refineries?

find about on Google and be horrified.

When I worked in Saudi in the 1970's we STILL had one running (the last in the world).

Re: Steam Hose?

as long as it is a valve that you can always get to quickly and shut off fast, that's cool and at most a bit embarrassing - I have NEVER left a clamp loose (this week...)... reaching in around a blown out water glass and twisting a valve handle 3 turns is another matter.... which is why many full si...

Re: Steam Hose?

CBREW: very clear observation on your part the problem with steam in rubber hose is not always temperature or pressure, but with the cutting action of steam on the interior surface of the hose...remember that steam moves at supersonic speeds and does things very differently than simple high pressure...
