Flame spray parameters
Hi all,
I've just started to look at our 6P-II flame spray gun.
First hurdle - How do I convert the metco parameters in their tech bulletin to suit my A3000 system with its NLPM input requirement?

Thanks,
Jim

RE: Flame spray parameters
hi,
That converter is for plamsa not oxy-fuel flame spray. It is very good though and I use it frequently. I'm using oxygen and acetylene through a 6P-II. the specific coating I'm looking at is Metco 308NS with the following book parameters;
Oxygen 35 psi with 43 flow
Acetylene 15 psi with 50 flow.

RE: Flame spray parameters
Hi Jim

Your parameter source should tell you which flow meter the flow settings relate to (GF, 2GF, 3GF) The Metco manuals for these particular flow meters should have flow correction graphs or tables for working out actual SCFH. Then you will need to convert SCFH to NLPM (not forgetting correction for temperature Smile see converting-lpm-to-slpm-t-544.html ) You can use link provided by Ion conversion/arflow.htm to convert from SCFH to NLPM, just enter value in SCFH box and read value in NLPM ignoring other results.

If you have no joy with the flow meter manuals, I will try and dig up some info.

RE: Flame spray parameters
Thanks for that Gordon, Very helpful as always.
The specs are for the 2GF flow meters with the standard pressures which means its a straight forward SCFH to NLPM converstion. For the powder above I get 18.8 and 21.9 NLPM for the oxy and acetylene respectfully. I'll give it go when I get a minute...


They do like to make it difficult though don't they!! Smile

Jim,

1 lb of apples has the same weight as 453,6 g of cheese although they have different taste.

Hi Ion

Quote:1 lb of apples has the same weight as 453,6 g of cheese although they have different taste.

Cryptic Happy0193 agreed, but this only helps with Jim's final part of the conversion - SCFH to NLPM.

Probably what is not clear

Quote:Oxygen 35 psi with 43 flow
Acetylene 15 psi with 50 flow.

is that these flows are not SCFH but Metco Flowmeter Readings (2GF) which only means something to a Metco 12E, 5P or 6P etc. using old Metco parameter settings Sad Problem is converting these first.

RE: Flame spray parameters
Haha,
Thought I was on the wrong forum then, been brewing up some lbs of apples to make cider - Very easy as it happends and not too bad eitherSmile
As Gordon rightly pointed out I ment the Metco FMR units, or as I have been informed by Metco the "banana" unit! I found we don't even that the right nozzle for this powder but I think I know how to come at them now.

RE: Flame spray parameters
Hi Jim,

How's your process development going?
As i have just acquired an 6PII-A gun with 6C controller.

If you are using Acetylene-Oxygen set-up, there shd readily available data on start up parameter, esp on 308NS.
Hope all are well with you. Have you accept the coating metallurgical requirement?
Hope you can share with me if there is any challenge on this process.
As for mine, so far so good, still in testing phase before putting into operation.

All the best.

Regards,

RE: Flame spray parameters
Hi all,

I am new to this forum. I would appreciate if anyone could provide me the table or formula to convert 2GF (from the Sulzer Metco Tech Bulletin) to 6C (our existing system).

Thanks and Regards,

Hi kc77

Sign0016 to the Surface Engineering Forum.

Ashamed0002 thought 6C automatic control unit used same flow meter tubes as 2GF. Would not surprise me if I'm wrong though as I've not much experience or memory with these units.

Number of options:
  1. Check to see if information is not already included in your manuals for the equipment
  2. Ask Sulzer Metco for information
  3. A few of our members I think have this equipment, so hopefully they can advise

Failing the above, post back calibration info on actual flow tubes (e.g. SCFH nitrogen @ 50psig & 70 F), may be printed on side of tube. We should then be able to work something out even if it is the long way round Happy0193

RE: Flame spray parameters
Hi Gordon,

Thanks for the advise. However, as for the 3 options you advised me on, I have the following answers.

1. Check to see if information is not already included in your manuals for the equipment
The manuals have been misplaced by predecessor and hence this is out of question.

2. Ask Sulzer Metco for information
My local Sulzer Metco rep don't have the information.

3. A few of our members I think have this equipment, so hopefully they can advise
This is my last hope. So I would appreciate if anyone could help me on this before we have to go the long route.

Thanks and Regards,
kc77

RE: Flame spray parameters
Metco provides applicable technical bulletins that can help you to improve your workflow. One of the Bulletins relevant to your A3000 system is NLPM Input Requirements, which outlines the various parameters that need input when using NLPM.
To convert these metco parameters into a format that will work with your A3000, open this Bulletin in Metaco's Tech Navigator and look for the "Conversion" tab. On this tab, you will find a list of conversion tables that allow you to adjust the values as necessary. Select the table appropriate for your needs and enter the required information into its corresponding cells. Note: Ensure all values are entered correctly, or problems may occur during data entry or processing.
