    hi all
    I need sum advice on threading a pipe cam connector nipple I have tried to show as many aspects off it the bit I want to thread is 1" OD blanked off with welded end I will have it drilled out to make a open pipe then try and get a thread on it stainless looking to put ball valve on to it
    these were expensive when I got them and have only one so this must be a one shot solution

    One shot Bill......entrust it to an engineering workshop.

    If it is stainless it will need a specific type of die.

    Unless agreed otherwise, they f*** it up they source a new one.

    i agree with pappa john that needs to be set up in a lathe to ensure the thread is central and true so off to a local machine shop

    What you have there is a tri clamp. Do you need to replicate the same again. Try deltastainless.co.uk and nero.co.uk.
    The threaded part looks like 1"BSP it will be an off the shelf part.
    Comercial fuel solutions do some threaded pipe parts.

    Hi Bill they are all of the shelf tri clamp fittings. The one with the end blanked is a hose tail. It then has had the end welded closed. You could also try dixon europe in Preston. Give them a call you will find them very helpful. What thread do you need.

    it's just to put a 1" or 3/4 valve on for the boiler to drain to the collar on the brewery I am building to ingress capacity I have the 50l plant but setting up 150l plant .
    it's getting busy with orders

    If it's 1" OD then it will be 3/4" BSP or possibly M25 (probably fine thread).

    Should be able to run it off in the lathe.
    Do you have a pitch gauge?
    Is it BSP? Unlikely to be metric.
    If we had the threaded bit it wouldn't be difficult to establish dia/pitch.
    Any local machine shop worth its salt should be able to do this.

    Bill I agree with pj, that's an engineering workshop job but cost wise I should go down andymans route first, it may be cheaper.

    Looks like you could thread it 3/4" BSP, then put a 1" to 3/4" BSP reducing bush on it to replicate the threaded end you already have. If you have no luck with Andymans suggestions, I could spin it up on the Myford if you are stuck ?
