Code requirement
Code requirement
(OP)
I have used A269 Gr 316L seamless tube with 0.89 mm thickness to build a sensor for ultrasonic flowmeter.
As per A269, only Flare test & Hardness test is applicable under mechanical test.
But customer is asking for tensile test for tube material. I have consumed all the tube for production & i have no samples to do the test.
The sensors will be used in a piping(Flowmeter body)The design code is ASME B 31.3.
Can anybody specify where in ASME B 31.3, this tensile requirement is specified.

RE: Code requirement
I tried that option,but mill also don't have the samples of that heat. they have no records of tensile values as well.
Mill has rejected my request as tensile requirement was not specified at the time of ordering of material.
So can i straight away reject the request of customer, as the code is also not referring tensile requirement?
RE: Code requirement
Instead of rejecting the customers request, go back to the customer and inquire as to why they want tensile test results. Explain the situation using the fact that B31.3 does not specifically require tensile testing if the material is supplied under ASTM specification.
