Could anyone explain why this tolerance value is applied to the pipe wall thickness or diameter? Does it apply to cast pipe, as well? Thank you.

I am also interested in Y value for ferritic cast iron pipe according to B31.1 and B31.3, latest version. Anyone, please with an answer!

I am looking for formulas and recommendations for design of a Vibratory Bowl Feeder. Please indicate any literature on topic. Thank you very much.

Thank you all. Good info and advice.

The part is a ring and deformation is simply upsetting the ring to about half of its height. It's the ring test for lubricants.

I have small parts made from 12L14 cold drawn with hardness about 90HRB. What can I do to soften the material which will be deformed to a lower height. Would heat treatment be influenced by the lead from the material? Thanks a lot for your help.

I am looking for special threads used for quick opening of jars, bottles, etc. I am interested in standards and specifications, and also in calculations of forces, friction, etc, for different materials with such threads. Thanks for any ideas.

I was not clear enough. I am interested in compression test for metal forming operation. The test was developed by Avitzur and continued by Male and Cockcroft. Thx for info and sorry for confusion.

I am interested in more info, especially the formulas to draw the curves for friction coefficient. Thank you very much for your reply. sgc

For more countries look at: http://rru.worldbank.org/DoingBusiness/FAQ.aspx The study is for sale but under "Comparative Data" it is possible to get some info.
