Hi,
i have a question with regards to a well being pumped off. what exactly does it mean other than the fluid level is below the nipple. What kind of stresses migh this impose on the traveling unit of a rod insert pump, specifically the traveling valve.
Hi,
I’m looking at welding a 1.5" d barstock of nitronic 50. The material is Austenetic 209 SS. I’ve decided on a welding rod of 309L SS. From doing a carbon equivalency calculation it looks like this material should be preheated between 400 and 700F (calc from ASM #6 welding book). Post heat...
For some odd reason over the last week, ive had trouble mounting samples. I use a little bit of epoxy on the face and then fill the back end with bakelite. the hydraulic fluid ran out the othr week but i fixed that problem and the jack works fine now. i did get a new order of bakelite in in the...
I am looking for more information with regards to Rockwell 15N. I know it is a superficial testing method, and that it uses a diamond tip. From the rockwell machine i have it suggests that a different indentor is needed. Does anybody have more information regarding this testing method. Thanks.
So i have a bizzare question/ problem with some 316 stainless steel. I have two parts that connect together, than came from the same heat number. the larger part is corroded and is also harder (33HRC compared to its counterpart at 12 HRC) The smaller part however has become magnetized. The area...
Hi all,
I have an Material Test Report for a material that has a Y.S of 30000 psi @ .2% offset. Heres the question, the spec the previous guy wrote say 35000 psi @ 1% offset. Is there a conversion for this to compare apples to apples.
So Im fairly new here, and have a question with regards to why some inconel is magnetic and some others are not. Im assuming right now that it has to relate to the elements in the material. Inconel 600 series a Ni-Cr is magnetic, where a 718 series is Ni-Fe is non-magnetic.Thanks in advance.
