    Aluminium 4045 mechanical properties

    Sorry Swall, I expected this to be a reasonably straight-forward request but I am grateful of your reply. To CoryPad, I'm fully aware of the requirements for Tensile Testing, however we are faced with 7 tons of Clad sheet without any testing being done prior to the cladding. Stangely enough...

    Aluminium 4045 mechanical properties

    Thanks for the info so far. To give you an insight as to why I need the tensile strength of 4045; I working on a unit that has 4045/3003/4045 clad plate involved. In order to qualify the plate for use in a CatIV pressure vessel I need to do Tensile tests on the Pre-Braze material and I need...

    ASME, Plate & Bar Heat Exchanger

    Thanks for all the help so far, I've managed to grab a few contacts from your suggestions. Unfortunately I do have to insist on the ASME Quals it would be awkward for me to explain why at this moment but if I could have avoided it I would have done.

    Non-Metallic Baffles

    I've built small Oil cooler stacks with Acetal baffles with no problems. I've also used Nylon 66 for tubeplates for a hydraulic oil cooler, with the tube glued into the plate. But you do need to check compatibilty and temperature limits with most non-metallic materials.

    Compatibility between N-Hexane & Aluminium

    I need to prove, from an acreditted source that Aluminium in 5454, 3003, and 4045 Alloys are compatible to use with N-Hexane in both Gas and Liquid states. Can anyone give me any pointers where to start looking?

    Has anyone ever used electric water pump?

    I've used EMP on a couple of projects with no complaints even after some severe test work. Nice flexible unit does what is says on the can.

    heating fuel lines with 12 volts

    We build a small Heat Exchanger with a number of variations that is used to heat Vegetable oil or reclaimed veg oil using the hot water from the vehicle coolant hoses. One of our customers has a neat control system that only allows veg oil into the fuel system when it is hot enough and also...

    scraped surface heat exchanger, application

    From my (25 year ago) recollections, both chocolate and toffee would benefit from this type of exchanger. I used to work for a large Confectionary company in the United Kingdom, whilst doing my apprenticship one of the regular chores was stripping and rebuilding the scraped surface exchangers...

    Internal countersinking.

    We have a production job to drill multiple holes in a closed box section component. I need to countersink the inside of the box section to remove any burrs etc caused by the drilling operation. We have tried the conventional manual internal deburrers. I am sure that I have seen a gadget that...

    Air/air vs Water/air intercooling.

    The fins look too small to me to be that efficient and the route for the air flow looks a bit to tortuous to be "Pressure drop" thrifty. Take a look at Titan-lite.com Extremely accurate, with the benefit of filling the hole unlike the cylindrical units from Laminova.

    We use Flowdrill, with a fair amount of descussion and further experimentation we have reduced speeds quite considerably, it's worth trying. Have you tried rivnuts?
