View Full Version : Invented hydraulic pipe benders for 1 3/8 - 15/8

15-12-2016, 11:42 PM
Hi my name is Steven I'm a refrigeration engineer with my dad ran own business for 10 plus years . We've made a hydraulic pipe bender that can bend 1.3/8 and 1.5/8 pipe with ease and the tool is small and easy to use . Also hoping we can bend 2.1/8 pipe to just on with that . I'm thinking of patenting the idea would just like some feedback if any one has used hydraulic pipe benders or think there's a market for the tool because don't think it would cost to much to make. Any input would be appreciated thanks

There are so many hydraulic pipe benders out there already, what makes yours suitable for a patent application I wonder.

Can you send me link to them so I can see what there like because I haven't seen a great deal of them

Mines a lot different to them and it's for copper there steal as it says on the info not suitable for copper pipe and the former sizes are not same as for copper pipe plus my benders don't push up with ram in middle as it would kink the pipe because we tried that u have to use guide with it and it doesn't even ripple the pipe . All ready spoke to my friend at Hrp refrigeration suppliers and he thinks it would do really well as there's no hydraulic pipe bender that they sell that can bend 1.3/8 1,5/8 and 2.1/8

Sounds promising, good luck with it.

thanks appreciate it hope I can get it all sorted hopefully see if get some good feedback . We've bent 6m of 1.5/8 pipe with sets 90 , 45 all in it and no need for brazing saves loads time and looks so much better. thanks again ��

Registration as patent take a long time and a lot of money.
Maybe you want to check with big tool company to buy it from you.
Chinese will copy it in no time. You will not be able to protect a patent around the world, very expensive.

Could the tool company just copy the idea if I don't protect it some way just don't no what the best way to go bout it really never done ote like this before thanks for your msg

Quite a limited choice for refrigeration pipe benders as the larger sizes seems you are stuck with the Hilmor style on the big yellow frame. That costs about 800 so if you can compete with that then I guess there would be some sort of market, don't think you can even hire them out.
Some VRF systems get up to the 1 1/8"+ so would be handy there, especially outdoors from my point of view.
Patents and the like I know nothing about except it costs a lot. Might be worth looking into licensing the design to a manufacturer instead like gets suggested on Dragons Den. Maybe Peter Jones might invest, his old man was an AC guy.

Good luck!

Hello Steven

It's a small world, I know you and your dad, (I used to work with him).

Good quality pipe benders in that size would be usefull and I'm sure
if your dad is involved in the design, it will do the job.

To patent it, it has to have somthing that is unique, like the way the
hydrolics fit the formers or the way the pump works, otherwise it
will be almost impossible to protect.

There are benders for water pipes, be carefull they are different.

You have a few options, one is to protect it and produce it yourself
or another option is to licence it to somebody like Jayvac or Rothenberger
and let them pay you every time one is sold?

Pete at Polar Pumps has experience of designing a product and taking it
to market, he pops in here quite often. Maybe he could offer you some advice.

Anyway all the best and tell your dad I said Hi,
I'll have to pop round with a few cans of Guinness over Christmas.

Hi rob what's ur last name so I can tel him . I've just told him but he said ask for his last name haha and he would never pass down a guinness . that's rate nice thing to say He has put lot effort and attempts with them . That's really good to no shall I ring polar pumps and ask for him or have u got the guys number . A like the options uve said least give me abit more of a idea on what to do next . He made them years ago but we never got round to taking it further and now I want to give it ago and see if we can do something with it , you never no until Uve tried . Hope u have nice xmas to it is a small world crazy .

Hi rob just realised it was u can you send me ur number so I can get in touch please u still work for Hrp

Hey u no never no my girlfriend said I should go on dragons den ha Cheers mate yeh I no them Hilmor ones they were really hard to use and that's why we made these hydraulic ones we've used them loads on nearly every crop store Installation and there small ish so good for transportation . Think il go down the licensing root just need to make few phone calls to see what todo really appreciate your comments I made this thread to get some feedback of other refrigeration engineers and now starting to think it could work regards Steve

I did industrial and commercial refrigeration pipe fitting for 8 years.
We had a ratchet bender for the big sizes.

I don't think a hydraulic bender would be as quick.
