    Default Need New Tubing Vendor

    Anyone have a reliable distributor for some .625" x .188" wall DOM 4130n Tube. The ID of .247 to .253 is critical. Customer doesnt wanna pay for gun drilling and reaming. Our current distributor cant produce the tolerances.

    don't have a source for you, but to get the best info, you need to specify what quantity you buy. (obviously you arn't talking mill run amounts) who are you using as a distributor currently, and who have you tried? why are you specing DOM instead of seamless in that?

    If there's a Kilsby Tube Supply out there in the Aland Islands, I have always had good luck with them. They had an outside sales lady who was super sharp.

    But +/- .003 on the bore, good luck with that.

    Not sure if they have that size, but my only local supplier for DOM is Metal Supermarkets in Richmond Virginia.

    Looks like that is a rare size/wall:

    Yeah im actually in Pennsylvania. dont know why it showed canada. Yeah we have called over 20 different places and all but one said no about the .249 id. I dont understand how anyone can claim milspec on something they can provide. especially when youre paying an extra $6 a foot for that tolerance.

    Im guessing were gonna have to tell the customer the cost is going to increase because we have to get the material gun drilled.

    At one point though it wasnt a rare size. Its aircraft grade seamless tube. But about 10 years ago that ID spec sort of went out the window and nobody was able to provide it any longer. So our final customer is rather cheap and doesnt wanna pay for the gun drilling operation. but the part that goes inside the tube needs no slop.
    So hence why the ID is super critical. I just figured id ask if anyone had a supplier they knew of that could handle this request.

    Seems to be several gun drilling shops in the NW Pa area.
    The local hi-pressure companies sell "pipe" that is simply barstock gundrilled.

    Was talking to one machinist, they sold "3-090 pipe" which is 3" o.d. barstock
    with an .090 hole thru it.

    IIRC 3' lengths.

    Yeah this jobs been a pain in our ass for 30 years. For 20 years we had no problem getting the spec. But now since most of these tubing mills are offshore. And they just dont have the quality.

    Yeah were gonna have to call the customer once McKnight gets back to us on this bad batch of tube. To start getting stuff gun drilled.

    The photo is what we have to make 330 of for april. And 10,000 by the end of 2022.
    America needs to start getting on their game and make this tubing within the +/- .002 tolerance again.

    Have you talked to SSAB? They introduced Docol R8 to replace 4130N, maybe they'd be more interested. They sell direct, not through distributors. Docol R8 Tube - Racing just changed forever - SSAB

    Cost comparison to 4130n? Were going to need initially 209 feet. But over 11,000 feet for the total order.

    I haven't bought any yet myself, but my friends who use it say the cost is comparable at small quantities (100-200 feet)

    Have you tried Wicks Aircraft by chance? They have pointed me in the right direction several times, even when they did not stock a particular tube.

    Did you try Superior Tube? They would have been able to supply what you need back when, don't know about now, and don't know about minimum orders or sales only through distributors. My dad was an engineer there from about 1963-2012, and I worked there a couple of summers, plus tagging around after my dad at other times.

    I find it sad that since all this material is made offshore now there is no consistency. One batch might be in tolerance and one batch later jts .030" over
