Hello, I have seen several old posts from 'JohnRBaker (Mechanical)' using 'grip program' to export point data (x,y,z) from NX native file in the form of .dat file thread561-379920 (see attached example). I'm wondering if any of you could please help me modifying the code to export the point...

Thank-you metengr for your input. It clarifies a few things for me. However from the manufacturer of barstock and incomming quality (for machined products) points of view, what is the difference b/w making barstocks to either standard... are they both not hot or cold rolled products?

I was wondering if I could change Change A479 with A276 for pressure application (for SS316L material)? I have been told that A479 is suited for B&PV application and A276 for structural application. Could some one shed light on this topic? Regards, bssem

I am looking for industry accepted tolerances for various manufacturing processes (metals and plastic processing). Are there any industry norms to control these tolerances? The manufacturing processes I am specifically interested are: Investment Casting Pressure die casting Deep drawn metal...

Thank-you metengr, WOW.. does it mean that we could use barstock per SA 479 when we specify SA 182 on our flanges? bssem

Can bar stock material (per ASME sec. II - say SS316L per ASME A 479) be used to make flanges in pressure vessels per ASME B&PV std.? I have notes in ANSI B16.5 that only Forgings / Castings & Plate Stock is Permitted. Pl. Comment. Thank-you in advance for your suggestions. bssem

SA-249/SA-249M Welded Austenitic Steel Boiler, Superheater, Heat Exchanger, and Condenser Tubes SB-691 Iron-Nickel-Chromium-Molybdenum Alloys (UNS N08366 and UNS N08367) Rod, Bar, and Wire Per your question, you are therefore comparing Tubes with Rod/ Bar/ Wires. The spec. for AL6XN Tubes is...

For manufacture of a custom flange for pressure application I was looking for European equivalence to SS316L plate stock (per ASME A 240). My major concern for the equivalency is chemical composition. Can someone suggest me a European equivalent to SS316L plate stock (per ASME A 240)...

For my process condition (various aggressive chemicals @ -25 deg C / -15 deg F) I have been advised by our marketing dept. to select Perfluoro-elastomer (FFKM) - Kalrez / Equiv. grade suited for the low temperature service (-25 deg C / -15 deg F). 1) Can anyone suggest me a FFKM compound that...

Thank-you All for your feedback. BillPSU you are correct with your assumption that we are doing a circular weld around circumference of the part. The dimension of the bore is 0.339 with tolarence of +/- 0.8 thousandth of an inch. As you have said the welding is dependant on many variables, will...

I need to TIG weld two machined (cylindrical) SS316L parts. Both parts have a identical central bore which has to be perfectly alligned after welding. I have considered using various centering features and clamping options but was unable to get the allignment of the central bore after welding...

Thank-you All, I have 2 questions I would like to have guidance on: 1) Can anyone pl. suggest and work done on the condensation through a polymeric barrier (say virgin PTFE) by means of Permeation of process fluid (at steam) at elevated pressure and temperature. I am specifically looking for the...

Can anyone pl. suggest and work done on the condensation through a polymeric barrier by means of Permeation of process fluid (at steam) at elevated pressure and temperature. I am specifically looking for the approach to measure and estimate. cheers, bssem

Thank-you ALL for your invaluable contributions cheers, bssem

Thanks TVP, Could you post the other mcguire thread numbers so I can catch-up with you?

We are OEM suppliers of instrumentation. There has been a debate on the effect of surface finish on the corrosion resistance of a given material (SS 316L) in given corrosive environment (acids or high chlorides). Can someone pl. guide me if any such studies have been done to prove that - an as...
