Bend radius for 2507 super duplex tubing

I am looking for information on the minimum bending requirements for 2507 super duplex tubing.

I was told that AMSE B31.3 section 332.4.2 states that super duplex tubing must have a 10x D bend radius to prevent the fiber elongation from exceeding 5%; I do not have a copy but have been told that it does not states super duplex tubing. The actual section states that is a requirement for tubing that requires impact testing. I am not familiar with whether or not super duplex tubing requires impact testing. Can any one familiar with ASME B31.3 know if it applies to super duplex tube or have any information on minimum bending requirements on super duplex tubing?

Thanks in anticipation

Are you talking about instrumentation tubing, usually, these tubing are not classified as piping.

Google tells me that "Steel bend shoes are required to bend SAF 2507 super duplex tubing with a Swagelok bench top tube bender."

I also found a copy of ASME B31.3 here

GPSVN,

Thanks for the information on swagelok and the link to ASME B31.3.

I have checked to see if it is piping or tube that we are speaking about and it is piping.

Thanks again

Will you please elaborate on the piping specification, design and operating pressure/temp, service, etc...

I also found a copy of ASME B31.3 here ... according to gpsvn.
