guidelines on manufacturing high pressure flanges
(OP)
we are in the process of buying a 3 axis milling machine with hopes of making flanges for the oil and gas industry example;6 inch 600#,my question is,what sort of legal paperwork is going to be required if we sell these? Also who is responsible for MTR's?





RE: guidelines on manufacturing high pressure flanges
You will need to buy all of the applicable specs, read them and understand them.
In many cases they will refer to raw material specs and testing specs. Buy those also and read them too.
Some flanges can be machined from plate, some cannot.
The traceability starts with how your quality system tells you to write your PO, what material and documentation is required.
In some cases you will use the chemistry and properties from the raw material MTR. In other cases you will have the RM MTR, a secondary product chemistry, a heat treat certificate, destructive mechanical testing, and then you can generate an MTR.

Once you "think" you understand the specifications, Order a few from the manufacturers already making them, see the documentation shipped with each flange.
