Have you seen this on a Borde?

I dug out my Borde Stoves and wanted to compare each to the other and noticed only 1 gas what looks like a date stamp?? Has anyone else seen this? I can barely make the letters out. But the numbers look like 1057. It’s stamped in the tube kinda like reverse Braille looking text.
All text is this!

“EN 1057 WIELAND”

 

I’m digging out a magnifying glass to get a better look

 

Hi, the EN 1057 is the European Technical Standard for copper and copper alloy pipes of high standard

In 1996 the latest specification for copper tubes, EN 1057, was adopted across Europe. In the UK it was published as BS EN 1057:1996, “Copper and copper alloys - Seamless, round copper tubes for water and gas in sanitary and heating applications”. It replaced the previously familiar standard BS 2871 Part 1: 1971, “Copper and Copper Alloys - Tubes - Copper tubes for water, gas and sanitation”. In 2006, EN 1057 was further revised to support the essential requirements of the EU Construction Products Directive (CPD) 89/106/EEC and the EU Pressure Equipment Directive (PED) 97/23/EC.

The Manufacturer of the tubing appears to be WIELAND:

Looks like it was put on by the manufacturer of the tubing, I think it is a quality specification

Best regards,

Wim

PS., Edit; looks like George beat me to it with proper info! Thanks George @kerophile

 

Hi, I note from the website of Wieland that they state:

“Our copper tube is processed to meet the product specifications and our customers' requirements. Straight tube and coils are produced.”

So Wieland would seem to be capable of producing the coil of the Borde stove, not just provide the tubing.

Best Regards,
Kerophile.

 

@kerophile @Wim awesome. Some good info. I always wondered how Tgey made such perfect coils and makes sense to just have the tubing manufacturer do that part for them.
Well thanks to everyone. I was just wondering if mine was a clone or real deal.

 

Here’s the one with the tube markings. It’s never been fired. The other isn’t old faithful. Well used but never abused and needle is intact and has never been overtightened by myself. As much as I love my Primus 41 and 199 etc I love my Borde most. It has never let me down and is just fun to use. Don’t get me wrong I love all my stoves but there’s something cool about a Borde. I hope one day to find a Sigg set that was made for the Borde. I want a shirt Borde someday. Maybe a skinny one also and another with the burner on top of the tank. I’d trade pretty much any stove I have for those three Borde and a Sigg setto Match them! Well if they are unused that is. Haha. I can dream and wish right? It’s Father’s Day! Happy fathers day to all the dads on this forum! I wish you all the best today!

 

The last picture above is the adjusting tools I have. Top two I made the bottom is original came with my Borde. Very top is titanium. Middle is stainless steel and bottom original is unknown to me?

 

Nice start. I only have one.

@hikerduane
Thanks. You only have1 but lots of others that I don’t have any of yet. Haha. I bet most are a lot more rare and cost more than what little I have too. Which Bordedi you have? Like mine or the skinny or short type? Or the one I really want where the burners on top the tank?

 

With those markings on the tube, it might have been rebuilt in the recent years.

As to making coils like that, you fill the tube with sand, salt, or a low temp alloy like Wood's metal, and make it like you would a coil spring. Then empty out the sand, salt, or melt out the Wood's metal, and Bob's your uncle!

That trick works great for making very tight bends in fuel and brake lines, made me a buck or two here, since nobody else here has figured out the trick to doing this!

@Murph I’ve done thesand thing a few times making alcohol stoves. Works well

 

@AngryDaddyBird , the salt trick comes into play when you work with Pyrex glass tubing - dissolve it out in boiling water.

Murph

 

@Murph Never tried that but now I know about it. Never had to use pure tubing though.

 

and a reasonable piece of (metal wire) coat-hanger will work fine, too...

 

@yetlet
I have not tried a coat hanger but have used brass rods, stainless rods and titanium rods to make the adjusting tool. I’m sure almost any metal wire would work. I used an aluminum tent peg in the past when I forgot or misplaced my Borde flame adjuster.

 

I made my adjuster from an old bicycle spoke!

 

Same here. A friend gave me a titanium bike spoke.

 

Mine's not that posh...

 

somehow I knew kerophile would have the answer right off the bat.
