Heat Induction Bending of High Strength Pipeline Pipe
Heat Induction Bending of High Strength Pipeline Pipe
(OP)
I need to know how to heat induction bend high strength pipeline material and maintain mechanical properties within their original tolerances. Specifically I need the chemistry for the mother pipe, the bending rate and the bending temperatures. Can anyone help me find this information?

If you have an induction bending machine for pipe/tube, all of the parameters you are asking above are pipe size and material specific, and require you to qualify an induction bending procedure. I have visited enough vendors that specialize in this forming method that most have a procedure that has been optimized for pipe size range and material.

we would like to enter this pipeline bending market. we do not have the technical knowledge of what chemistry we should begin with in the mother pipe nor do we know exactly what bend speeds and bend temperatures to operate the bending machine to achieve the after bend mechanical properties. we are not looking to get this information or knowledge for free but, are looking for help or direction in how to gain this knowledge and ability. can you help us with this endeavor? thank you in advance for your time and trouble.

Here is what I would suggest, find a local full service metallurgical test/consulting laboratory. Have them work with you to qualify a bending procedure using pipe material that you intend to qualify. The reason I suggested working with a lab is they should have a staff metallurgist that can provide guidance for testing requirements and interpret results. Yes, there will be a cost, but this cost is necessary and part of doing business to ensure you have a qualified bending procedure. Most likely customers, like myself, will ask to review a procedure and how it was qualified.

You really need to discuss with your steel manufacturer / suppliers

Attached is the download link for ISO 15590-1, you may find ASME-B-16.49 from the other internet download sites.
Additionally the following book, would also be useful:-http://w
Both ASME and ISO documents calls for a bending procedure to be developed and approved by the end user.The procedure has to meet the list of essential variable with are well specified in those documents.
Prior to production bending vendor has to satisfy all the essential variables through successful mock-up or qualification bend.
To start with, a good interaction with the pipe mill would be an excellent point of start.Receiving data on piping materials spec,nominal properties, forming chracteristics, hot/cold, forming process/es,process control,precautions during forming,inspection and Q.A, metallurgical testings, heat treatments etc, would provide good backgound information.
As sugegsted by metengr, you may engage consultants to qualify your bending procedure and achieve required level of consistency.
Thanks.
