Great video. A lot of information spoke about. Mr Lawton knows a lot about his pipes. Well done both
Great demonstration and information thank you to Lawton and Peter well done guys 👍🏼🙂♥️
I keep my formers clean and also thinly coat them with a little silicone grease. Smooth ripple free bends.
Hi Lawton tubes & PB - Many years ago I decided to invest in the purchase of a Rems Curvo electric pipe bender - primarily for bending stainless tubing which it does with great ease and perfect bends - I also hoped to use the machine for bending standard British plumbing copper tube 22mm to 35mm - however I was very disappointed to find that the copper tube rippled badly using the Rems machine. Only after many phone calls to Rems did I eventually manage to get an answer as to why this was happening - it turned out that the machine was designed for the European copper standard - this is now table Y in Britain which as Lawton tubes have clearly explained is a thicker walled tube but with the same hardness (half hard). Great informative video Lawton.
Really useful video as I'm only now starting in the trade. once again, nice one PB and thanks Lawton tubes.
Great film well done pb and Mr Lawton, I love Lawton copper products. Lawton copper is king, Thank you 👍👍👍
Very interesting. Nice seeing a video of some use for a change.
In days of old when it was either galvanised iron or lead pipe then came copper pipe and we all believed the copper-to-iron fitting was the best fitting ever invented.
Copper pipe came in, Blue band Yellow band, and Red band, Blue band being the thickest wall.
Yes I was an apprentice to Noah.

So it begs the question, why don’t we use the 1mm wall thickness tube in the U.K. as standard and drop the 0.7mm
30% more expensive 😩😩😩🔥🔥the quote
@@paul_my_plumbs_uk mo money, mo money!
Because 0.7 tube bends very well if used in the correct type of bender. Why overengineer any more than we already do just so we can use foreign pipe benders?
And, as others have said, cost. In Italy, they use thin hard copper for the straights and soft copper for the bends. But due to cost, they rarely use copper at all. Our old UK tube was thicker, back in the day when we didn't have central heating and only really used it for hot and cold water pipes. If the UK market kept using the same quantity of tube, but switched to thicker wall, would current copper supplies even cope with demand? Now that's a question...
Been 20yrs since we used Copper in America for residential. Everything is PEX now. Nice to see copper being used .
42 years in the HVAC industry and I am surprised to hear you talking about plumbers doing work with a mechanical bender.
So in UK it’s very much 70 / 30 in copper, we are one of Europe’s largest users of copper in plumbing I’m pleased to say 👍 Plastic has its place mainly in underfloor heating where it’s key not to have any joints or fittings.
Sadly with most plastics it all ends up in landfill when finished with unlike copper which can be 100% recycled time after time. Sustainably is much becoming a BIG in construction so copper in States will be seen a lot more for sure 👍
@@LawtonTubes that’s a good observation, but PEX pipe is left installed for much longer than copper, so it’s not a simple comparison.
Really in Florida we use copper everyday your must not be in the field bro
Because most heating systems in UK don’t run at very high pressures so making 0.7mm more than suitable for the job so why pay 30% more for a tube that’s not necessary.
Fascinating
Aye Mr Lawton knows his shit mate 👍
When I was learning I was told it's all in technique and he also proved to me why, he showed me how he could purposely ripple copper and it's all in the technique of bending. Hard to explain but it's basically to do with one fixed point and one moving point, not moving them together like scissors? I dunno something like that
It's all in using the right pipe. It all may look the same but it's not. You have to be a pipeologist.
Love a bit of table Y we use it for condensate lines and solar when brazing
I've had the odd ripple, and I put it down to the benders need a little cleaning.
Sometimes it ripples due to pulling the bend too fast.
Have my dads record benders over 45years old still spot on
When a tradie can't get anything level they make them a plumber.
Still using mine after 30 years.
And finally we get the Answer we get sold shit pipe in the uk . Thanks pb for answering my all time question 👍👍👍👍👍👍👍👍👍👍 I have bought loads of bloody benders trying to stop it
Alternately, benders not designed for UK pipe standard. The gas pressure is minimal, 1/3 PSI (2 PSI in some new residential builds). Copper tube 15mm dia x 0.7 wall has a bursting pressure of 58 bar ; over 840 PSI, so a colossal factor of safety. For comparison, plastic carbonated drink bottles contain pressures of 30 to 50 PSI, and fail at over 150 PSI.
Your shit is a plumber's bread and butter.
I use a BenditNow bender (designed for UK table X tube, not the Bahco shown that was apparently designed for table Y), greased the roller bearings when new, clean and wax the guides every few months, and I don't have rippling, well, once every few months just before I rewax my bender lol. Usually use Wednesbury or Yorkshire tube, both from UK...
Will I have any problems using a 15mm pipe with a few little ripples in a cold water pipe?
What benders are those that are being used?
I’ve had Bahco bender and for that reason got rid of it. Monument master bender is the way forward
Pb there making it look effortless with 15mm unit that bloke
I have found over the years that if your pipe guide is not fully engaged in the pipe bender, your pipe will ripple regardless.
Wall thickness on the fittings look thicker than the pipe wall ..?
I had a set of screwfix pipe benders that i used for many years . They were great but started rippling. I figured they were worn out so i bought some new hilmor benders that day, which also rippled the same pipe. I figured it was the pipe at fault. I often work with a mate. He has rothenberger benders. He pulls a bend no ripples, i pull a bend in the same pipe with the same benders and it ripples. So im guessing its me and my technique some how? 🤷♂️
Try cleaning the guides and formers, grease the 'bearing' of the rollers on your bender and a light bit of furniture polish on the guides and formers. I put beeswax polish on my guides and formers once every few months and it seems to prevent rippling.
Modern Hilmor benders are very poor compared with the old Hilmors, by the way.
Bending too fast. Slow down.
Interesting
"Would a standard elbow fit on this?" he asked, not realizing that using elbows make the entire bending issues irrelevant.
Dodgey Copper !! Plenty around 🤣
The water pressure in Europe is higher than the UK and seem to use pressure reducers at the mains in coming?🤔
I've had a pair of bahco 15mm benders for over 12 years very rarely does it ripple just use it properly
Having recently worked on my old ½" copper pipes, I was amazed how much thicker the walls were compared to modern 15mm. On bending the 15mm I found every second bend ended up slightly rippled, even using a new pipe bender & the same tubing. Basically modern stuff is c*** compared to the past.
The old red line copper pipe couldn't be bent . Table Y could be used underground if I remember correctly.
My new hillmor bender creases 22mm I blame the copper thickness and did my old bender
It's the benders, they are very bad quality. They have lower tooling tolerances since they moved to production to China. Buy a 2nd hand bender or a bend it now. Want to 180 15mm bender, get a 2nd hand record solo. I got one for £15 never rippled a bend.
🤘😎🤘
well interesting ,, so a bit of pipe is not just a bit of pipe ,,,,
We commonly bent 35, 42 & 54mm copper tube with a Ratchet Bender in the 80 & 90’s.
Though maybe 90degree bends in these sizes are not common, kicks & offsets are still required.
I’ve a 15mm Bacho Bender & it bends without ripples. Anyone want to buy it, make me an offer👍👍
Definitely would be interested tbh, drop me a message and we'll chat, I'd prefer to collect though
£5000😂😂😂😜😜😜
@@killerbean9911 We’ll chat??!! Mate let’s talk Turkey, or should I say it’s as rare as Hen’s teeth.
Make me an offer son👍👍 Though if I’m honest, it’s no better than the monument one, which it too has its limitations.
@@paul_my_plumbs_uk Not enough son!!
@@TheDickPuller 😂😂😂👊🏾👊🏾
But in the real world how much is rippling really an issue?
Looks bad and induces turbulence in the flow.
You're only supposed to bend the bloody pipe!
En mi opinión está bien pero cuando doblas se estira i sea delgasa la pared del tubo y más rápido liquea eso es bueno para la electricidad porque nada más yeba cables en miopinion
Table Y tube wall is 43% thicker than Table X, not 30% thicker.
it never used too
There is some one at fault it happens very regular
Logo looks too familiar
“Who knew?”
The information is out there, so why would anyone *not* know?! I’m certain the UK has the laziest and most stupid plumbers in the world.
Europe use 14mm or 16mm pipe not 15mm
no, its still 15mm just thickers walls
@@marzocchi92 no, it's 19/32" Metric is a lie!
Looks like I need a new bender then , my old rothenberg ripples most time
