Increasing strength, reducing fatigue failure, torque transmission, better handling. Longer tong space which allows more connection recuts and Reducing wear rate on tube OD through protection by the center wear pad. Drill Collar also same.
Hi I will inform you soon, Rig Tec mobile application is under process, in that application have an option for attending live class through video streeming. Once I uploaded in play store , I will inform you through my channel. Thanks for your comment
when setting up the wall,,,, the buggy should be over the 4,5 hole if you have the buggy at the end of the STANDARD you have the END effect distorting the Mag field
If you are using the air jack or any kind of jack for calibration, END effects will not affect the MAG. Because the pipe holder is situated at the end of Standard pipe .Buggy sensors are approximate 5-6 away from the end of Standard pipe. Two arm roller is attached before the Buggy sensors. So end effects will not affect the wall calibration But residual mag will affect both calibration.
Simple way is, if the Tubing is brand new you can get from the markings. The is used or no markings, you can get from manufacturer certificates. Because in tubing lots of copied connections are in the industry .
You are right and this dimensions not for QC . These dimensions helps the people who worked in drilling industry to easily identify the connection. They are not using the micro meters or vernier caliper for taking dimensions. In rigs they are using OD caliper and scale for taking dimensions. OD caliper have certain limitations, these limitations I explained in my videos. So I always says the approximate values. If you are using the OD caliper you can get the values what I said in my videos. In my videos I also recommend the OD caliper and scale. Thanks for your comment.
I = 1200xOd / no of turns of coil This equation no have any traceability. 2 to 3.5 A you can use for DP. The procedure is defined only the reference kick height. If you apply high mag current , the graph will show the high kicks from small pitting, cut , and gouges. If you apply minimum current the graph will fine. The mag current is dependent on your pipe condition, if the pipe is in worst body condition and you are giving the high mag current, the unwanted kicks with large hight will show in the graph. So the ensure or prove up the unwanted or noise kicks from defects/cracks.

@@Venkateshyadav_1 you need a taper gauge with contact points of .144. Most numbered connections are 2 inch TPF and 4 TPI. Find a fully formed threads on the start of the connection. Place your taper gauge, zero it out and count 4 threads backwards on pins. For pins your taper ranges from .167-.169 For boxes you start in the back and move up 4 threads. And your pitch diameter ranges from like .164-.166 Note it’s good practice to check the taper in multiple spots to ensure your machine is cutting consistently
BSR (Bending Strength Ratio): On bottomhole assembly connections, the ratio of the box section modulus to the pin section modulus. BSR applies only to connections on drill collars and other stiff-bodied components that are run in the BHA. It does not apply to HWDP connections, except the one immediately above the drill collars, or to the connections of any components that are not normally run in the BHA.

@@rigtec123 ok entendido. Un favor seria amable de explicar en el próximo video hacerca del tayper. Cual es el tayper de cada conexión o como medirlo. Para saber como calibrar mi conocimetro dependiendo de la conexión.
