Due to a design constraint I will be using a Angular Contact Bearing to calculate the thrust load using a load cell. The test setup is horizontal. Is there any method to determine the loss of thrust load when using a angular contact bearing to measure the thrust load. Please let me know if you...
Hi,
I am trying to find a API specification that is available or a API specification that is likely to provide the testing requirement for a downhole linear pump. Please let me know if you need more information.

Hi All,
I have a question regarding click type torque wrench. Our assembly shop utilises a click type torque wrench Which has a removal head. Beacuse of a design constraint we had to design a head. The head was longer than the standard heads. Does it affect the torque applied. We are supposed...
Hi,
I am trying to find the most commonly used Quality specification for O-Rings relating to the oil industry. We supply downhole pressure containing equipments and work to API 5CT specification. Hoever i dont belive there is a specification for o-rings on that. But i did come across...
I have a query regarding heat affected zone due to TIG welding. A 1.38" OD tube with a wall of 0.085" wall is TIG welded. There is a wire of 16AWG with the insulator running under the wall. I am trying to find out if the Heat from TIG welding will have a consequence on wire being snapped. Is...
Hi,
Machinery's Handbook gives a formula for calculating the torque which is not relating to the length. I believe this assumes that there is minimum length of thread engagement available, which is calculated from the same machinery's handbook. I have a situation where i dont have the minimum...
Hi,
I have a threaded connection which has a direct tensile load to break the thread is 12,000 lbf. I am trying to find the torque that can supply this load to the thread to break it. The thread is 0.4375-20UNF.
The load on thread and the torque load is perpendicular as you are aware of. can...
Hi All,
I am working on a quality procedure for radiography (cast protectors). I have very less knowledge of radiography in relation to the oil industry. can i ask you what is standard that the oil industry use in terms of radiography and is there good online material that you can suggest for a...
Hi,
We are designing a electronic housing for a high pressure completion. As for the qualification purpose, we are trying to test its integrity to collapse. Does anybody know of a test facility which does collapse pressure testing (ie in a tank) at 125 deg c. in Aberdeen, UK

Hi,
I have from API quoted a test requirement of 20J on the transverse direction on a 10mm x 10mm specimen for a V Notch impact test. The material supplier has done the test on the longitudinal direction and has obtained a value of 75J. Is there any means of converting this value to transverse...
Hi,
I am to draft drawings for parts which has a male and female threads. These parts are required to be orientated using the threads, I am not aware of dimesioning threads with a tolerance to the orientation. The tolerance however is + or - 4.5 degree and both the threads are to start from 12...
Hi,
I have recently come to know that when you are gauging a BS thread onto a ANSI gauge the gauge is showing as failed on NOGO but the BS gauge is fine. I did through browsing came to know that there were difference between these threads but i could not know what these differences are. can you...
I am looking for a Carbon steel plate that is rated to -40 degree. I did come across BS-4360 that has a material 40DD which is rated to -30 degree. Can you recommend a carbon steel that is similar to this but rated to -40 degree C. Can you recommend a british standard as above or an american...
Hi,
I work in the oil industry. We are developing new products which requires mating of new pressure connections.I have been told Aircraft industry uses good and new types of mechanical connections. Some of the type of connecting that we use are threading, flanges and welding. I did find...
Hi,
I have a circular bore on a rectangular surface. I am going to align the circular bore and bolt like flange. I am not aware of any industry standards relating to rectangular flanges. As this pressure housing is going to see pressure from outside, i was going to stick to some industry...
Is there any standard or regulation for the kind of pressure testing liquid (oil) that can be used in the oil industry. As i believe sometimes using oils with a higher flash point can be hazardous to be personal on rig site.

Hi
I am recommending drift mandrel sizes for Premium Connection. At the moment i cannot find much detail on API 5CT detailing on drift mandrel tolerances on OD.
Is there any other API standard that recommends tolerance or did i miss it while going through the 5CT standard.
Can you advice...
Hi
I am trying ot find the temperature derating factor of the below materials
1. AISI 4140 (YTS 80K PSI)
