We have some in-service pipelines we will have to determine mechanical properties.
In the past, I have sent cut pipe cylinders of abandoned pipes to the lab for mechanical testing and obtained the results I needed.
Can anyone recommend a tool that can provide information on Yield strength and...
Hi,
My question is regarding steel pipe fittings. I understand there are various wall thicknesses available for line pipes.
1) My question now is are the wall thickness for the butt weld fittings (elbows, tees, reducers etc.) limited to light weight, std., x-heavy etc.

Hi,
What is the minimum test pressure requirement and duration(for transmission pipe) in class 3 location if gas is the test medium? This is for pre-installation test of short pipe.
Thanks
Hello All,
Does anyone know of any pressure testing requirement or code for pipeline elbows. I am talking of gas pipelines - Transmission and High pressure distribution pipelines.
For instance, what is required when pretested pipes are installed with elbows? Thanks
Hello All,
I'm reviewing a work order for already installed line and I came across "Full encirclement saddle."
My question is: Is this a pressure containing component? I know that it may have a vent hole, but I want to know if a full encirclement saddle is pressure containing or non-pressure...
I have short stopp fitting described as below. Is the information enough for me to determine the ANSI rating, max. test pressure and design pressure respectively? If yes, kindly explain more. Thank you
