Window Cut in a Crude Oil Pipe Line

You asked about how to cut a 1 sq. ft. hole in a pipe having 1" thick walls, did you not? All the rest that you mentioned just now was not part of the original question and is completely irrelevant to it. A hole is hole - it doesn't care what comes after. It's still just a hole, and that's all you asked. That hole doesn't care one whit about the effects of crude oil on fused silica - and that's an experiment you should be performing separately in any case. You know, to prevent an oil spill in case that window fails? Why are you planning to find out whether it will or not on a live oil pipeline? The more you say, the scarier it gets.

You asked about cutting a hole, when there's a shitload of people building that pipeline who could do it for you in a heartbeat. You asked about cutting a hole. Now you're back-pedaling.

Selles, get away from that pipeline. You don't know what you're doing.

best way is to use the waterjet ,with the template you can cut in any shape for this thickness.

That's a very good suggestion sohail. GA.

The question still remains, as to why a person, the OP, who cannot figure out how to perform a rudimentary fabricating task, is in a position to be even contemplating this?

Alarm bells started ringing when the requirement for radii at the corners of the window to be cut was an epiphany for the OP......

Well, I see our latest troll is still with us.

Hey, Selles, if you're too thick to have figured out by now that there are no pipeline contractors on the forum who will do your work for you, how can you possibly claim to have invented a new form of energy????

Grow up, hire a contractor and quit trying to convince the members here that you're anything other than a FRAUD!!

I do not believe your intellectual property crap and I do not believe that you are anything other than a blow-hard, trying to blow smoke up our collective butts.

I'll gladly sign a NDA and look at your contraption, and give you an honest assessment of the technical merits, as I see them.

If you want to call me on this, PM your e-mail address to me and I'll respond.

Ball's in your court, serve or shut up!

Selles, instead of marking my comment OT, why don't be a man and prove that you have something other than wishful thinking. Send me your contact information.

Cynics Anonymous.

I don't normally post Anon, but thought I'd make an exception in the case of our delusional friend.

But I'm back now, to challenge the savior of the world Selles to show me his bona fides, if he has any.

Having dabbled in GHz waveguide tuning in my younger days, I feel marginally qualified to have an opinion.

Hey, maybe that exoplanet is the source of Selles new microwaves.

Well, at first Selles said in his 'Silicium' post that they were using a "...new form of microwaves" but here says a "new form of microwavING" - a different meaning altogether. Now I'm willing to give Selles the benefit of the doubt as I suspect English is not his native tongue, but, on the flip side, his command of English is more than enough to have convinced me that he sloshes when he walks and that's a fact.

English is not the issue. It's the fact that Selles is blindly demanding that we tell him how to perform a simple, everyday (to pipeline builders) cutting operation while claiming to have this revolutionary technology that is nothing but wishful thinking, or worse, a marketing claim with no validation.

I'll give him credit for sucking us all in to this farce.

Yepperdoodles. That's where the slosh part comes in.

He asked about cutting a square hole, then the bit about about microwaving the whole 750 k bbl/day and from there it went downhill at the speed of..well..new forms of microwaves.

Btw, that exoplanet radiates microwavings. Techniques. Building a technique-demodulator even as we speak. It uses a silicium diode (as opposed to a pot of germaniums).

This whole thing just reeks of someone not thinking things through, starting with square holes and sharp corners - where it really went off the cliff even before the subject of heating ALL of the crude with microwaves came up, and not just the perimeter where the problem is (viscous drag), a problem which has already solved and far more efficently than the method Selles is proposing. There are more problems with this that I haven't mentioned and won't because I think we've kicked this dead horse enough.

This is the product I think we used to use on refined product pipelines to reduce viscous drag.

Well at least you didn't get OT'ed for suggesting that science is based on the laws of nature.

If real science is not based on the careful observations of nature and actions/interactions of all things around us what exactly is it based on?

Well, one thing Selles has learnt from all this early on is how to abuse the GA/OT system.

I thought your OT'd reply was spot on and so I took the liberty just now of de-OT'ing it. Hope you don't mind...

Thanks but most here know I find the whole voting system petty and childish.

In fact I rarely ever use it unless its to undo an unfair OT mark because some pinhead was having a tantrum and thought they would toss a few out.

As far as honest and true GA votes from me I think I may have given out 2 or 3 now and I blame those on my overindulging in ice cream and candy causing my blood sugar to go too high for a short time impairing my judgement.

Lol.

Truthfully I've never intentionally given either kind and, in every case it was because I was trying to jab that 'Report' button and missed.

Those pipefitters and contractors scrambling all over it outside the site cabin do, Mildred.

Hottapping? API RP 2201.

Typical Hot Tap installation consists of a tapping saddle,

gate valve, and Hot Tapping Machine. The installation is

tested, the valve is opened, and the cutter and pilot drill

advanced. When the cut is completed, the cutter and

pilot drill are retracted, the valve is closed and the Hot

Tap Machine removed.

Sorry for not reading all the posts, but has anyone suggested installing a flanged "T", maybe with a stop valve and such?

Would allow the energy source to be advanced into the flow area, but also removal for service. This brings fabrication bact to standard components and methods.

Since Selles is a troll who has taken revenge on many here, childishly I might add, I will tell you that the whole scheme is a technical joke and an insult to intelligent engineers and technicians everywhere.

Selles, feel free to zap a few more GA's for all of us who didn't swallow your line of bull-crap.
