Friend,IF You mean the glass insert Don't try it, Secure a loaded replacement tube. Only bad things happen when trying to field replace glassware. 50 years at this business has taught me that this needs to be left to experts.
GOOD LUCK
Pete

easier said than done. It takes tens of thousands of dollars worth of custom-built equipment & specialized training to reload an x-ray tube insert. That is why there are not many reloading operations.

There are some different ways to do it, the most important thing is to remove all the air and humidity from the oil inside. To have new oil is better but you can use the used oil if you keep it in a clean and sealed can meanwhile insert exchange, this must be done in a really clean environment, clean hands and tools.
What brand of insert are you going to change, most of them don't need special tools. And if you don't have a vacuum pump available, you can warm up the oil once it its back in the housing to force it to release the air, etc. and make it expanded to create a vacuum effect when its cooling and seal the housing correctly.

Do you mean the Tube assembly in an x-ray system (CT, Cath, rad, R&F, etc.) or the glass insert of an x-ray tube assembly. If the latter, that is something that normally isn't or can't be done in the field. You would need new gaskets for the tube sections, fresh new dielectric oil, a vacuum system to draw out any air from the tube before sealing (closing) it up for use. If the tube for a system, it depends on the brand and type of system. Which can be as easy as just swapping out the tube assembly to hours of checks and alignments.

Why you want to repair? We can help with new OEM tube with low price. Also we can change inserts for your tube. But you need to send to Russia

What are the problems with the tubes? If it is rotor errors, you need to reload, if arcing, you need to change the oil and maybe wipe down the glass. Open a bad one up and look. You can not break broken!

I repair tubes in the field all the time. I just fixed a Straton Z ct tube in the field. Use new transformer oil that the local electric company uses. Make sure the leave room in the bellows for oil expansion as the tube heats. De- bubbling is the most important part of the job! I let the tube sit for 12 hrs with one end of the tube as the high spot. If the tube has an oil pump (CT tubes), run the pump for the 12 hrs. Remove the bubbles, rotate the tube and heat exchanger in every direction to move the bubbles to the high spot and remove them again. Bubbles will explode the insert!

I have not worked on a Phillip MRC tube, but with that said, this was also my first Straton tube. That tube is still working without any arcs! The physics of an x-ray tube is the same. I doubt they are using any special oil. Not that we should not, the best oil is Clearco silicone transformer oil. You have to make sure that you drain the tube and heat exchanger completely. I have used this oil in an old Picker PQ tube with wonderful results. If the tube is bad, what do you have to loose? Take your time. You can try it in stages. First a straight oil change, transformer or silicone. If not, you will need to open the tube and look for arc traces. Where are you located? Is the tube dead?

Dear Mr. Tantawi, what kind of equipment you want to change the insert, as far as I know MRC inserts are for SKF bearings, not for x ray tube. Regards.

I am not familiar with the Toshiba tube, but with that said, it is an x-ray tube. If you have high voltage oil, it will work. Put the fill port at the highest point. Fill the tube while putting some pressure on the expansion bellows. Fill it to the top and put the plug back in. On the Seimens, I used the quick disconnects as the fill port, put the back conner as the high spot and ran the pump. Turned off the pump and rolled the tube so the bubbles would move to the disconnect. Run the pump for a day (12hrs min). The most important thing is not to rush. I have never used a vacuum pump in years of fixing tubes. As for the dissolved gasses, there will alway be some, even on a new tube. HV oil has already been degassed well. It is 11 months that the Straton Z tube has been working and going on two years for the Picker tube that I changed the stator motor on! I fixed them both on the CT room floor. Make sure anything that touches the new oil is very clean. The AC should be on to keep the humidity in the room low, just normal AC, nothing special. Do not leave the new oil container open to pickup the humidity. Remember, with out the oil, the tube is bad, so if you fix it, you gain, if you don't, no loss, it was already bad. God's speed.

Let you customer that a tube repair will take about 5 days if all goes well. You might want to do regular oil changes to extend tube life.

The Straton tube insert is very strong. The failure occurs in the plastic housing that directs the oil around the insert. I use a dremel tool. Look for the black dots in the plastic. Follow the dot through the plastic with the tool. When you are done, it will look like Swiss cheese. Next you will fiberglass boat resin with a DE-bubbler. Use half the DE-bubbler the mold people use. Mix your resin slowly so bubbles are a minimum. Tape one side of the holes you made and pour the resin into the other side. Many pass for many holes. Mix in small amounts. As with all types of tube repairs, take you time. Next you will need red insulating paint, I used Glyptal. Lightly sand the back of the insert and paint it. Paint the plastic. Remember to change the oil in the heat exchanges as well as in the tube. The tube fixed in September of 2014 is still going at a high volume place, they normally got six months from a tube.

End to end or rotation? CT or X-ray? End to end is set by shims already there, rotation is done by eye. Tube position centering will require when it is reinstalled.
