Mill test pressure
Mill test pressure
(OP)
I would like to know what exactly means mill test pressure, is the pressure at the factory before a piece of pipe leaves the manufacturing plant or is it a design pressure...?
Thank you
Thank you

Pardon my ignorance but if I should require pipe for a certain design pressure, should I go for a pipe of about the same mill test pressure? A pipe with mill test pressure of about 3.5 times my design pressure?
How does mill test pressure guide me in evaluating the suitability of the material [pipe, say] for my requirement?

this specification clearly defines the hydrotest pressure.
This pressure test must be conducted by the pipe manufacturer, or another code permitted material certifying
bodies.( PG-11 in section I permits boiler manufacturer making certification, also section VIII Div1. etc..)

This is regardless of mill pressure test in mill shop.
So we can not consider the mill pressure test instead of field pressure test which is requirement of Code.
