Search 16 stainless steel tube diameter stainless steel rod barter against 14mm

[jime]

Hi everybody

I take advantage of this section for my announcement.

I'm looking for a length of about 50mm of a tube of 16 inside, I could swap it for solid rod (I have 14mm and 4mm) or buy it if necessary, the post will take care of bringing us closer

Hello
I have this:
1/2 "stainless steel tube
so d int: 15
d ext: 21
th. 3
interested?

Hello

that could be well, I just have a doubt about the interior space of the reactor, I have the impression that I misunderstood, I believe that it is necessary a rod of 13 mm for a tube of 15mm, either a space of 1mm on each side of the rod
christophe's sheet on the reactor:

The usual diameter of the inner tube of the reactor is 1 / 2 inch, 15 16 mm was inside, but other dimensions may be suitable. Ensure that the clearance between the rod and tube either to 1 1,5 mm.

With my 14mm rod and a 15/21 tube I will have a clearance between the rod of 0,5 mm on each side of the rod, I inquire and I confirm that.

Hello

The duct have standard measurements
1 / 2 thumb pipe
the external measurement is standardized at 0,830 "or 21mm
the internal measurement is variable depending on the thickness of the duct
most often at 0,580 "or 14,8mm

the pipe ducts 1/2 21 ... 15
standard rods is 1/2 inch or 12,7 mm
originally it is the dimensions taken by Panton

It confirms what I read on the quanthomme site

Important note: It has recently been found that the 12mm steel rod used initially in the pyrolysis chamber has a slightly too small diameter if a 15x21mm tube is used (see photo at the bottom of the page) as pyrolysis chamber. (It takes a maximum of 1mm of space between the steel rod and the tube). It is therefore recommended to use a steel rod 13 mm in diameter to improve the performance of the reactor (improvement of the Venturi effect and the thermochemical effect).

I could have 12mm rod but I drop

otherwise I saw the plans of the suitable reactor, they use a 14mm rod for a 15/21 tube, so I will try with the two rod diameters, 13 and 14.

after precise measurement of the internal diameter.
I report to the caliper (at 50 th)
from 16 m / m
it is a seamless stainless steel tube
but on the 1st post I read 50 m / m
now much more ....
1 m; 2m; 3m ...... ????
my bar at 1480 m / m
but:
it will be necessary to thread each end and in stainless steel it is hassle
why not take a simple non-galvanized tube?
believe in my experience, you will gain!
other than that i guess you need 500 m / m
and I'm ready to give it away for free, but how do I get it to you?
I am in southern Alsace .....

good evening pilot68

A tube with a diameter of 16mm is perfect to go with my 14mm rod, I will have 1mm of space between the rod and the tube, I can't ask for better.

In fact I said that I needed more length because I have 3m of 14mm rod and I count G + pantoning the diesel vehicles of my family, so I am interested in the maximum possible length even if I have to pay you for the tube.

why not take a simple non-galvanized tube?
believe in my experience, you will gain!

If I choose a steel tube, will I have rust problems? To tap I count on the tapping material for steel tube of my grandfather, plumber.

For shipping, I think that 1m pieces packed in a box and sent by colissimo by post should not be a problem and should not be too expensive (5-10 euros). It will just have on the packaging that there is room to stick the colissimo label. For the fees, I can send you a check or make a bank transfer, as desired.

the stainless steel tube is non-magnetic, is it suitable for a pantone? I guess you have to be sure.
I am ready to yield up to 1 meter long,
but for shipping I prefer to cut it into several pieces
which will allow me to better affix an address
being naturally confident I will send you these pieces and
you will reimburse me the shipping costs + 1 euro symbolic

Hello

concerning the non-magnetic stainless steel tube, I do not have sufficient knowledge, I will know it after experimentation
I do not have a precise answer, because I saw assemblies having outputs with a steel tube and a stainless steel tube?, the plans of the Apte reactor are also all in stainless steel so I will try this solution

the length suits me, if I stick to the plan of the reactor available on the site, a reactor measures between 230mm and 300mm without the ends, cut it into 3 pieces, one of 300mm and two of 350mm for transport, is it's possible ?

a big thank you for the price, don't hesitate, if one day you need a stainless steel rod, it will be with pleasure.

I leave you my coordinates by mp
